Server Quality Checklist

92%
Profile completionA complete profile improves this server's visibility in search results.
  • Latest release: v0.8.7

  • Disambiguation3/5

    Many tools have distinct purposes, but there is significant overlap in domains like financial reports (multiple tools for reports, snapshots, statements), candlesticks (three different candlestick tools), and DCA plans (nine tools). The detailed descriptions help but the sheer volume of closely related tools creates potential for misselection.

    Naming Consistency3/5

    Tool names use a mix of bare nouns (e.g., 'watchlist', 'news'), compound nouns ('broker_holding'), and verb-noun pairs ('create_watchlist_group', 'cancel_order'). There is no uniform pattern, and some tools are variants like 'candlesticks', 'history_candlesticks_by_date', and 'history_candlesticks_by_offset' which are inconsistent in structure.

    Tool Count2/5

    With 150 tools, the server is extremely large, covering trading, market data, financials, news, community, screener, and more. While comprehensive, this count is too high for efficient agent navigation and likely should be split into multiple specialized MCP servers. The typical MCP server has around 10-20 tools.

    Completeness4/5

    The tool surface covers a wide range of broker/investment operations: orders, account, market data, options, IPOs, DCA, financial reports, news, screener, and more. Minor gaps exist, such as lacking tools to initiate transfers, modify account settings, or handle margin lending, but overall it is highly comprehensive for a trading platform.

  • Average 3.9/5 across 135 of 150 tools scored. Lowest: 2.8/5.

How to sync the server with GitHub?

Servers are automatically synced at least once per day, but you can also sync manually at any time to instantly update the server profile.

To manually sync the server, click the "Sync Server" button in the MCP server admin interface.

How is the quality score calculated?

The overall quality score combines two components: Tool Definition Quality (70%) and Server Coherence (30%).

Tool Definition Quality measures how well each tool describes itself to AI agents. Every tool is scored 1–5 across six dimensions: Purpose Clarity (25%), Usage Guidelines (20%), Behavioral Transparency (20%), Parameter Semantics (15%), Conciseness & Structure (10%), and Contextual Completeness (10%). The server-level definition quality score is calculated as 60% mean TDQS + 40% minimum TDQS, so a single poorly described tool pulls the score down.

Server Coherence evaluates how well the tools work together as a set, scoring four dimensions equally: Disambiguation (can agents tell tools apart?), Naming Consistency, Tool Count Appropriateness, and Completeness (are there gaps in the tool surface?).

Tiers are derived from the overall score: A (≥3.5), B (≥3.0), C (≥2.0), D (≥1.0), F (<1.0). B and above is considered passing.

Tool Scores

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description adds no behavioral context beyond the annotations (readOnlyHint, idempotentHint, etc.). It does not mention potential side effects, rate limits, or output format, so transparency is minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, direct sentence that immediately states the action and subject. It is concise, front-loaded, and contains no superfluous words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness1/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is extremely minimal and does not explain what the market temperature time series represents, what units are used, or what the expected output looks like. With no output schema, this lack of context leaves the user with insufficient information to fully understand the tool's results.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters1/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The tool description does not add any meaning to the parameters beyond the schema's own descriptions. Each parameter (start, end, market) already has a brief explanation in the schema, and the description offers no additional clarification or constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'historical market temperature time series', which accurately conveys the tool's purpose. It distinguishes from sibling tools like history_candlesticks or market_status by naming the specific data type.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines1/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description only states what it does, not when it should be chosen over other history or temperature-related tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations (readOnlyHint, idempotentHint, destructiveHint) clearly indicate it is a safe read operation. The description adds no further behavioral context, but the annotations shoulder the burden, so a neutral score is appropriate.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words. While it is concise, it could benefit from more detail without becoming verbose, so it earns a 4 for being efficiently minimal.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is too minimal for a tool that likely returns complex statistics. Even though an output schema exists, the description should hint at the nature of 'statistics' (e.g., returns metrics like cost basis, returns, etc.) to help the agent judge usefulness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema provides 100% coverage with a detailed description for the 'symbol' parameter. The tool description adds no additional meaning beyond what the schema already states, so baseline 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose3/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description says 'Get DCA investment statistics,' which states a verb and resource, but it is vague given the numerous sibling DCA tools (dca_list, dca_history, dca_check, etc.). It does not specify what 'statistics' means or how it differs from other DCA endpoints.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. There is no mention of context, prerequisites, or exclusions, leaving the agent to guess the appropriate use case.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations declare readOnlyHint false, indicating a write operation, but the description adds no further behavioral context (e.g., that it places a live order, side effects, or confirmation requirements). It does not contradict annotations but provides no extra transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single short sentence, which is concise, but for a tool with 24 parameters and high complexity, the brevity feels under-specified. It does not front-load key guiding information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite having an output schema, the description is far too minimal for a complex trading operation. It lacks usage context, behavioral details, and any explanation of how to construct a valid request, making it inadequate for proper tool invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so all 24 parameters are documented in the input schema. The description adds no additional parameter semantic, so the baseline of 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (submit) and resource (grid trading order), distinguishing it from generic order submission. It is specific enough to convey the core purpose, though it does not elaborate on the mechanics of a grid order.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description offers no guidance on when to use this tool versus alternatives like submit_order or grid_replace. It lacks context on prerequisites, scenarios, or exclusions, leaving the agent without decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, covering safety and idempotency. The description does not add behavioral context beyond this, such as data freshness, rate limits, or potential side effects, which would add value.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is short but uses abbreviations (fo_, fr_, yoy, cmp) that may be unclear. It front-loads the action but lacks structure. It is not overly verbose but could be better organized.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of an output schema and 100% parameter coverage, the description adequately conveys the tool's purpose. However, it omits any mention of prerequisites, error conditions, or usage constraints, which would be helpful for a complete picture.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the input schema already documents all parameters well. The description adds some context by explaining output field semantics (e.g., fo_revenue shows actual vs forecast), but does not improve understanding of the parameters beyond what the schema provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it retrieves a financial report snapshot and lists specific fields (report_desc, fo_revenue, etc.) and report types (qf/saf/af). However, it does not differentiate from sibling tools like financial_report, financial_report_latest, or financial_statement, which likely overlap in functionality.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, nor does it mention any prerequisites or limitations. The agent receives no context about when not to use it or what distinguishes it from similar tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint as false, indicating a safe, idempotent operation. The description adds no further behavioral context beyond what the annotations provide, such as data coverage or rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise with two sentences, but the second sentence listing period values could be omitted since it's already in the schema. The structure front-loads the purpose, which is good.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has no output schema, and the description does not mention the return format (e.g., OHLCV data). While the name implies candlestick data, for completeness, a brief note on the response structure would help. The parameters are fully described in the schema, and annotations cover behavioral traits.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so each parameter is already documented. The description only adds a redundant listing of period values ('1m/5m/...'), which is also present in the schema. No additional meaning beyond the schema is provided.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'historical candlestick data by date range', but it does not differentiate from the sibling tool 'history_candlesticks_by_offset' which also retrieves historical candlestick data but by offset rather than date range. The title reinforces the purpose.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives like 'history_candlesticks_by_offset' or when not to use it. The description lacks context such as prerequisites or typical scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description only says 'Show' and adds no additional behavioral context such as data freshness, possible delays, or reliance on market data. Minimal value beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words. It is appropriately front-loaded and concise for a simple read operation.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite having an output schema and annotations, the description is too terse for a tool in a large family of IPO-related siblings. It does not indicate what constitutes 'detail' (e.g., pricing, dates, shares) or contrast with similar tools, leaving the agent unsure of its precise scope.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the baseline is 3. The description does not add meaning beyond the schema; it merely restates that the tool shows detail 'for a symbol', which is already captured in the parameter descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Show' and the resource 'IPO detail for a symbol'. However, it does not differentiate from sibling tools like 'ipo_calendar' or 'ipo_listed', which are also IPO-related. The name 'ipo_detail' suggests a detailed view, but this is not explicitly confirmed.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as 'ipo_calendar' for listing or 'ipo_subscriptions' for subscription data. The description lacks context about prerequisites or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate this is a write operation (readOnlyHint=false) with destructive potential (destructiveHint=true). The description adds no additional behavioral disclosure, such as that orders are submitted asynchronously, may be rejected, or that certain parameter combinations are invalid. This is insufficient given the tool's financial impact.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise at one sentence, but it is too terse for a tool with 13 parameters and significant complexity. While front-loaded, it sacrifices valuable context that could be provided in a few more sentences. It earns its place but could be more informative without verbosity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the rich input schema (100% coverage) and the presence of an output schema, the description's burden is reduced. However, it omits critical context like the fact that submission depends on account status, market hours, and order type validity. The description is minimally adequate but not complete for a complex trading action.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    All 13 parameters have full descriptions in the input schema (100% coverage), so the description does not need to elaborate on them. The description 'buy/sell order' confirms the side parameter but adds no extra meaning beyond the schema. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Submit a buy/sell order' clearly identifies the verb (submit) and resource (order), and it specifies the two possible sides (buy/sell). This distinguishes it from sibling tools like cancel_order and replace_order. However, it could be more specific about the context (e.g., securities trading) and omit 'buy/sell' redundantly with the schema's side parameter.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives like cancel_order, replace_order, or order_detail. There is no mention of prerequisites, market hours, or conditions under which submission might fail. Without such context, agents may misuse it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already flag this as non-readOnly and non-destructive. The description adds no further behavioral context, such as whether creation is instantaneous, if it requires confirmation, or if duplicate plans are allowed. It repeats schema info without enriching the agent's understanding of side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very short (two sentences) and avoids unnecessary words. However, it could be better structured (e.g., bullet points) for clarity. It earns a high score for conciseness but loses a point for lack of organization.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 6 parameters, no output schema, and many DCA-related sibling tools, the description is too sparse. It fails to explain what a DCA plan entails (e.g., recurring investments, how funds are sourced), what the response contains, or any constraints like minimum amounts. This inadequacy forces the agent to rely on trial and error.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so baseline is 3. The description restates frequency options and day parameters but adds no meaning beyond what the schema already provides. It does not explain 'amount' semantics (e.g., currency, decimal precision) or 'allow_margin' implications.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Create) and resource (DCA recurring investment plan). The name 'dca_create' reinforces this purpose. Among sibling tools like dca_list, dca_update, dca_stop, this is distinctly the creation tool, providing clear differentiation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives. It does not mention prerequisites, such as having a funded account, or that an existing plan might need updating via dca_update instead. There's no mention of when not to create a plan.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare the tool as readOnly, idempotent, and non-destructive. The description adds that it returns a 'distribution' of PE/PB/PS values, which is behavioral context beyond annotations, but does not disclose the format (e.g., histogram, percentiles) or any time scope.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, which is concise but may be overly terse. It states the core purpose without elaboration, which is acceptable but leaves room for ambiguity about the nature of the 'distribution'.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    An output schema exists, so the description does not need to detail return values. However, the tool deals with valuation distributions and could benefit from additional context (e.g., whether it returns historical or current data, or how industries are defined). Given moderate complexity and good schema coverage, it is minimally adequate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The single parameter 'symbol' is fully described in the schema (100% coverage) with an example. The description adds no additional semantic meaning, so a baseline 3 is appropriate given the schema already handles it.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves 'industry PE/PB/PS valuation distribution', specifying the exact valuation metrics. However, it does not differentiate from siblings like 'industry_valuation' (likely summary stats) or 'industry_rank', leaving the agent to infer the distinction from the term 'distribution'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as 'industry_valuation' or 'industry_peers'. There is no mention of prerequisites, limitations, or context-specific scenarios, leaving the agent without decision support.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate read-only, idempotent, non-destructive. Description adds output structure but the confusing US account statement may mislead about actual behavior, reducing transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Relatively concise with main purpose front-loaded. However, the confusing statement about US accounts wastes space and reduces clarity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Explains output structure and symbol filtering, but lacks explanation of differentiation from 'today_executions'. The US account parameter ambiguity leaves gaps in understanding.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline 3. Description adds meaning for 'symbol' (filter) but says US account parameters should be used via a separate endpoint, contradicting their presence in the schema and creating confusion.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states 'Get orders placed today' and lists return fields, distinguishing from siblings like 'today_executions' and 'history_orders'. However, the US accounts part introduces ambiguity about whether to use this tool or a separate endpoint.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Implies use for today's orders but does not explicitly state when not to use or mention alternatives. The confusing guidance on US accounts further detracts from clear usage direction.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, destructiveHint=false, which convey safety and idempotency. The description adds no further behavioral context (e.g., rate limits, data freshness, or side effects), but with annotations present, a score of 3 is appropriate.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with no wasted words. It is concise but perhaps overly terse; however, it earns its place by stating the core action.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has an output schema and rich annotations, so the description's job is reduced. It adequately states what the tool does but lacks context about the returned data structure. Overall sufficient but not enhanced beyond minimal.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a clear description for the required symbol parameter. The description 'for a symbol' adds no new meaning beyond the schema, so baseline 3 is correct.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states 'Get capital distribution for a symbol' with a specific verb and resource. It distinguishes from siblings like capital_flow and dividend, though it does not elaborate on what 'capital distribution' entails.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives like capital_flow or dividend. Context signals list many sibling tools, but the description lacks any comparative or contextual usage hints.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description adds minimal behavioral context. It does not disclose any additional traits such as response size, rate limits, or data freshness.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no waste. However, it could be slightly expanded to include context about the output or differentiation from siblings without losing conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has only one parameter and an output schema, the description adequately states the purpose. It could be more complete by mentioning that it provides detailed data versus the summary from the sibling 'dividend' tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The single parameter 'symbol' is fully described in the schema (100% coverage), and the description adds no additional meaning beyond the schema's definition. Baseline of 3 is appropriate since schema already covers the parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses the verb 'Get' and specifies 'detailed dividend distribution scheme,' clearly indicating the tool retrieves detailed dividend data. While it is distinct from the sibling 'dividend' (likely a list or summary), the description does not explicitly differentiate it from other dividend-related tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives such as 'dividend' or 'capital_distribution.' There is no mention of prerequisites, context, or excluded scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive, and the description is consistent with these. However, it adds no additional behavioral context such as data scope, pagination, or response characteristics beyond the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    One short sentence that immediately states the tool's purpose with no filler or redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a single-parameter, read-only tool with output schema and strong annotations, the description is minimally sufficient. It could be more specific about what counts as 'events and announcements,' but the output schema covers return details.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The single required parameter 'symbol' is fully documented in the schema with an example ('700.HK'), so the description adds no additional parameter-level meaning. Baseline 3 is appropriate given 100% schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description uses specific verb 'Get' and identifies resource 'investor relations events and announcements,' making the tool's function clear. It does not explicitly distinguish it from sibling tools like news or filings, but the resource name is sufficiently specific.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as news, filings, or corp_action. The description simply states what it does without context or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true, and destructiveHint=false. The description repeats 'Get' which aligns with read-only behavior, but adds no additional behavioral context beyond what annotations provide.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is very concise at one sentence with no wasted words. It is front-loaded with the verb and resource, making it easy to parse.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is minimally sufficient given the single parameter and existence of an output schema. However, it does not explain what a margin ratio is or what the output contains, which could be helpful for an AI agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% coverage, with the 'symbol' parameter fully described. The description adds no extra meaning to the parameter beyond what the schema already provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and resource 'margin ratio for a symbol', making the tool's purpose unambiguous. However, it does not explicitly differentiate from sibling tools like 'quote' that might also provide margin-related information.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. No context on prerequisites, limitations, or comparison with sibling tools is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate read-only, idempotent, and non-destructive behavior. The description adds context about data source (HKEX CCASS) and market restriction (HK stocks only), which is useful but does not elaborate on the 'detail list' nature or pagination. It provides some value beyond annotations but is not comprehensive.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence (15 words) with no extraneous information. It front-loads the key action 'Get full broker holding detail list' and efficiently conveys constraints.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple input (1 param, no enums) and presence of an output schema, the description is adequate but lacks differentiation from sibling tools. It does not explain what makes this 'detail' versus other broker holding tools, which is a gap for an agent deciding between them.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and the parameter 'symbol' has a clear description. The tool description does not add any additional meaning beyond stating it is 'for a symbol', which is already covered by the schema. Baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it gets a 'full broker holding detail list for a symbol', with specific constraints (HK stocks only, sourced from HKEX CCASS). This distinguishes it from sibling tools like 'broker_holding' and 'broker_holding_daily' by implying a more detailed list, but does not explicitly differentiate.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus its siblings (e.g., 'broker_holding' or 'broker_holding_daily'). There is no mention of prerequisites, limitations, or context for use.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool is simple with one fully documented parameter, annotations covering safety, and an output schema present. However, the description lacks usage guidance and does not differentiate from closely related sibling tools, leaving minor gaps in contextual completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema already provides a full description of the 'symbol' parameter with an example ('700.HK'), and the description does not add any additional parameter semantics. With 100% schema coverage, the description adds no extra value here.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states a specific verb ('Get') and resource ('company executive and board member information'), clearly indicating the tool's function. However, it does not distinguish this from sibling tools like 'participants' or 'shareholder', which might also provide related corporate information.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (1 required parameter, output schema exists), the description is adequate but does not fully address usage context or distinguish from similar tools. An output schema covers return values, so completeness is acceptable but not outstanding.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and the schema description for 'symbol' already specifies it is a security symbol with example '700.HK'. The description adds no additional semantic meaning beyond what is in the schema, so baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get the latest financial report summary for a security', using a specific verb (Get) and resource (latest financial report summary). It distinguishes from siblings like 'financial_report' and 'financial_report_snapshot' via 'latest' and 'summary', though not explicitly.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare read-only and safe behavior. The description adds temporal granularity (monthly) and output type (distribution), but does not disclose data freshness, limits, or other behavioral traits beyond what annotations provide.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single, efficient sentence with no filler. It is front-loaded with the key action and resource.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity, an output schema exists, and annotations are present, the description is minimally adequate. However, it lacks differentiation from related sibling tools and could benefit from more context about what 'distribution' means.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% for the single parameter, which already has a clear description. The tool description adds no additional meaning for the parameter beyond the schema.

With annotations providing a strong safety profile, a score of 3 is appropriate.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at 4 words, front-loading the purpose. Every word is earned, and there is no redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the low complexity (1 required parameter, rich annotations, and the existence of an output schema), the description is minimally adequate. However, it lacks context about what the 'summary' entails or how it differs from related tools. Completeness could be improved.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% for the single parameter 'symbol', which already has a clear description. The tool description adds no further meaning beyond what the schema provides, so the baseline of 3 is maintained.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Get institution rating summary' clearly states the action (get) and resource (institution rating summary). It implicitly distinguishes from sibling tools like 'institution_rating_detail' and 'institution_rating_history' through the word 'summary', but does not explicitly differentiate.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the agent knows this is a safe read-only operation. The description adds minimal behavioral context beyond the resource type ('institutional shareholders'). No mention of output structure or pagination, but the safety profile is covered by annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no wasted words. It conveys the essential purpose without redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is minimal but acceptable given the tool's simplicity (one parameter, output schema present). However, it could provide more context about the output (e.g., data fields) or usage hints, especially compared to siblings.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 100% schema description coverage, the input schema already documents the single parameter 'symbol' with an example. The description merely restates 'for a symbol', adding no new semantic value beyond what the schema provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get institutional shareholders for a symbol', providing a specific verb and resource. However, it does not explicitly differentiate from sibling tools like 'shareholder_detail' or 'fund_holder', which may also retrieve shareholder data for a symbol.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description offers no guidance on when to use this tool versus alternatives such as 'shareholder_top' or 'institutional_views'. Given the large set of sibling tools, this omission makes it harder for the agent to select the correct tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description mentions 'correlated news reasons', which adds some behavioral detail beyond the readOnly annotation. However, it does not disclose pagination behavior (e.g., that next_params is used for paging), or any limitations or edge cases (e.g., how the standard deviation is computed, whether the list is sorted by default). Given the annotations already establish safety, the description adds modest but not comprehensive behavioral insight.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise (two sentences) and front-loads the core purpose. The second sentence listing parameters is somewhat redundant but not overly verbose. It is well-structured but could have been slightly more compact by omitting the redundant parameter details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description provides the key context (unusual price movement threshold) and notes the inclusion of news reasons, but it does not explain the output structure or mention the use of pagination. Given the schema is rich and output schema exists, the missing usage guidance and pagination explanation leave some gaps, but it is not severely incomplete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The description redundantly repeats the schema descriptions for 'markets' and 'sort' but omits any extra meaning for 'date', 'limit', and 'next_params'. It fails to clarify parameter interactions or defaults beyond what the schema already provides. Since the schema coverage is 100%, the description adds minimal semantic value.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's function: retrieving stocks with price fluctuations exceeding the 20-trading-day standard deviation, and also mentions that correlated news reasons are included. This is specific and distinct from typical list endpoints, making the purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide any guidance on when to use this tool compared to other market data tools, such as 'quotes', 'candlesticks', or 'rank_list'. It lacks context about scenarios (e.g., 'use this to identify unusual movers for news analysis') or prerequisites, leaving the agent to infer applicability.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior, which cover primary safety traits. The description adds that it returns daily valuation rank, but does not disclose error handling, data availability, or output structure. With annotations handling the main behavioral context, this is adequate but not enhanced.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise with two sentences: one stating purpose and metrics, the other specifying date format. No superfluous words. While efficient, it could be more structured (e.g., bullets) for quicker parsing.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description should hint at the response structure (e.g., date, rank, industry). It only mentions metrics but not the format or frequency. For a data retrieval tool with rich context from annotations and siblings, this is a notable gap.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with all parameters described. The description restates the date format 'yyyymmdd' already in the schema, adding minimal value. It does not explain the meaning of the rank output or parameter interactions. Baseline score of 3 applies due to high schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves daily valuation rank (PE/PB/PS/dividend yield industry percentile) for a security over a date range. The verb 'Get' and specific metrics provide clarity, but it does not explicitly differentiate from sibling valuation tools like 'valuation_history' or 'industry_valuation'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for obtaining valuation rank percentile data over a date range, and specifies date format (yyyymmdd). However, it lacks explicit guidance on when to use this tool versus alternatives such as 'valuation_history' for actual values or 'industry_valuation' for aggregate industry metrics.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already provide readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds that the tool gets OHLCV data but does not disclose additional behavioral traits like response format, rate limits, or data source behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Extremely concise and front-loaded. Two sentences: first gives function and defaults, second lists period and trade_sessions options. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Adequate but incomplete. The description provides basics but does not explain response structure, data ordering, or how to interpret results. Lacks details that would be needed given the absence of an output schema and presence of sibling tools.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so baseline is 3. The description adds value by summarizing defaults and enumerating allowed values for period and trade_sessions, providing a quick reference beyond the schema's descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves candlestick data (OHLCV) and lists default parameter values. However, it does not differentiate this tool from sibling candlestick tools like history_candlesticks_by_date or history_candlesticks_by_offset.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description lacks any guidance on when to use this tool vs alternatives. No context on when to choose candlesticks over other tools that provide price data, such as intraday or history_candlesticks_by_date.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, so the safety profile is clear. The description adds little beyond the parameter values; it does not disclose additional behavior like data volume, output structure, or potential errors. For a read-only tool with rich annotations, this is marginally acceptable.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that lists the main action and enumerates parameter values. No redundant words, and it is front-loaded with the core purpose. Every piece earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has an output schema and rich annotations, the description adequately covers the necessary information: what reports are retrieved and the parameter options. It could be improved by mentioning that it returns full financial statements for the specified period, but it is mostly complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for all three parameters. The description repeats the parameter values (kind, report_type) but adds no new meaning beyond the schema. Baseline score of 3 is appropriate since the schema already carries the semantic load.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves financial reports and lists specific kinds (IS, BS, CF, ALL) and report types. This gives a clear verb+resource pairing. However, it does not explicitly differentiate this tool from siblings like financial_report_snapshot or financial_report_key_metrics, which reduces clarity for distinguishing usage.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. Given the presence of sibling tools focusing on key metrics, snapshots, or latest reports, the agent receives no context to decide which to invoke. No 'when not to use' or alternative suggestions are given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The tool has strong annotations (readOnlyHint, openWorldHint, idempotentHint, destructiveHint false) that disclose its safety and idempotency. The description adds no behavioral details beyond what annotations provide, such as data freshness or rate limits, but also does not contradict them. So a score of 3 is appropriate.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise—one sentence front-loaded with the core action. It is efficient but could include a bit more context without becoming verbose. There is no wasted text.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has an output schema (not shown), so the description does not need to explain return values. However, the description could provide more context about the data's temporal scope (e.g., current forecast vs. historical) or data source, which is missing. For a simple tool, it is barely adequate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema has 100% coverage for its single parameter 'symbol', already containing a description. The tool description does not add any extra semantic meaning or usage tips beyond what the schema provides, so it meets the baseline of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb 'Get' and clearly states the resource 'EPS forecast and analyst estimate history', distinguishing it from sibling tools like 'consensus' which cover broader estimates. The purpose is immediately clear.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as when to use 'consensus' for different analyst data. No prerequisites or exclusions are mentioned, leaving the agent to infer usage context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, covering safety. The description adds no extra behavioral context (e.g., what the calendar specifically shows). It does not contradict annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no unnecessary words. It front-loads the purpose clearly.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of an output schema, the description does not need to explain return values. However, it lacks details on the calendar's scope (e.g., dates, events), making it minimally complete for a tool in a complex domain.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    There are zero parameters, so the input schema is fully covered (100% schema description coverage). The description adds no param info, but none is needed. Baseline 4 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Show the IPO calendar' clearly states the verb (show) and resource (IPO calendar). However, it does not differentiate from sibling IPO tools like ipo_detail, ipo_listed, etc., which could be confused with this tool.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives. The description does not mention any prerequisites or context where this tool is preferred.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds no behavioral context beyond the basic read operation, but it does not contradict the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single clear sentence with no wasted words. It is appropriately sized for a simple read-only lookup tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's low complexity, one well-documented parameter, strong annotations, and an output schema, the description is nearly complete. It could be slightly improved by noting the source of order IDs or distinguishing from IPO order details, but it is sufficient for basic invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% and the single order_id parameter is already described as coming from today's orders or order history. The description adds no additional parameter meaning beyond what the schema provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's function: retrieving detailed information about a specific order. It is distinct from list-oriented tools like today_orders and history_orders, though it does not explicitly differentiate itself from ipo_order_detail or other order-related tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It does not mention that the order_id must come from today's orders or order history, nor does it contrast with sibling tools like today_orders, history_orders, or ipo_order_detail.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description is consistent with these annotations but adds no extra behavioral context such as error handling, response limitations, or auth requirements. With annotations present, this is adequate but not enriching.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no filler. Every word contributes to understanding the tool's purpose and key parameter.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read-only lookup tool with one required parameter, an output schema, and strong annotations, the description is largely sufficient. It lacks any note about behavior for invalid/missing topic IDs or explicit relationship with sibling topic tools, but these are minor gaps given the tool's simplicity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, and the only parameter topic_id is self-explanatory. The description's 'by topic_id' reinforces the parameter's role but adds no additional semantics, format constraints, or edge-case context beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the operation: 'Get discussion topic detail by topic_id.' It names a specific verb and resource, making the purpose obvious. However, it does not explicitly differentiate from sibling tools like 'topic' or 'topic_replies', so it falls short of a 5.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    There is no guidance on when to use this tool versus alternatives such as 'topic_search', 'topic_replies', or 'topic'. The description only states what the tool does without providing context, prerequisites, or alternative tool references.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds a few example event types but provides no extra behavioral context such as result scope, response size, or whether historical events are included.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no filler or redundancy. Every word contributes to conveying the tool's core function.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the low complexity (one required parameter), strong annotations, and presence of an output schema, the description is sufficiently complete for an agent to understand and invoke the tool. No return-value clarification is needed because the output schema exists.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The single parameter 'symbol' is fully described in the schema with an example ('700.HK'). Schema description coverage is 100%, so the description does not need to add much. It adds no additional parameter semantics beyond what the schema already provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly identifies the tool's purpose: 'Get corporate actions' with concrete examples ('splits, buybacks, name changes'). This is a specific verb + resource, but it does not explicitly distinguish itself from closely related sibling tools like dividend or capital_distribution.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is given on when to use this tool versus alternatives such as dividend, capital_distribution, or other corporate-event tools. The intended use is only implied by the tool name and one-line description.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false. The description adds no extra behavioral context, such as pagination behavior, rate limits, or data freshness. It minimally repeats the 'get' operation already implied by annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence with no wasted words. However, it could include brief contextual detail without becoming verbose, hence not a 5.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool is simple (fetch by plan_id) with full schema coverage and an output schema (not shown). The description is adequate for a read-only, idempotent retrieval. It lacks mention of pagination defaults but schema covers that.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so parameters are fully documented in the schema. The description only mentions plan_id, missing page and limit. It adds no meaning beyond what the schema provides, meeting the baseline of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'execution history records', and the scope 'by plan_id'. It effectively distinguishes from sibling DCA tools like dca_list (which lists plans) and dca_stats (statistics), making the tool's purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for retrieving history by plan_id but provides no explicit guidance on when to use this versus alternatives like dca_list or dca_stats. No when-not-to-use conditions or prerequisites are stated.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, destructiveHint=false, so the safety profile is clear. The description adds no additional behavioral context (e.g., data freshness, pagination, rate limits). It is acceptable but does not go beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Description is two lines, front-loaded with the main action, and every sentence is informative. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given that there is an output schema (not shown) and annotations cover safety, the description provides enough context for typical use. It could mention that the output is a financial statement object, but the purpose is clear. Siblings exist but their distinction is implied through parameters.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, but the description adds value by explaining the shortcut abbreviations for kind (IS/BS/CF/ALL) and report periods (af, saf, qf, q1/q2/q3) in a compact manner, which is not fully present in schema descriptions. This helps agents understand allowed values quickly.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the verb 'Get', the resource 'financial statements (income statement, balance sheet, or cash flow)', and scope 'for a security'. It lists statement types and report periods. However, it does not explicitly distinguish among siblings like financial_report, cash_flow, etc., though the specificity of kind and report parameters helps.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs. alternatives. No when/when-not or alternative tool mentions. The description assumes the agent knows when to pick this over other financial statement tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, so behavioral safety is well-covered. The description adds the period list but does not add new behavioral context such as rate limits, data staleness, or what happens on invalid offset. It neither contradicts nor significantly extends annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise (two sentences) and front-loaded with the key action and resource. The period list is useful but the description could be slightly more structured. It earns its space with no filler, but it is minimal.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given 7 parameters (6 required) and no output schema, the description lacks critical context: it does not explain how 'offset' works, how the reference time interacts with 'forward' parameter, or what the returned candlestick format looks like. The tool is moderately complex, and the description does not adequately compensate for missing output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, meaning each parameter already has a description. The description only repeats the period choices and does not add meaning beyond the schema, such as how to construct the reference time or what 'offset' implies numerically. Baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and the resource ('historical candlestick data by offset from a reference time'). It distinguishes from the sibling 'history_candlesticks_by_date' by specifying the offset mechanism, and it lists valid period values, leaving no ambiguity about what the tool does.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies use when you need data relative to a reference time, but it does not explicitly state when to use this versus alternatives like 'history_candlesticks_by_date' or 'candlesticks'. No guidance on prerequisites, limitations, or when not to use it is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, so the description adds return structure details (items array with counter_id, name, chg, lists[]). It does not disclose any additional behavioral traits such as ordering, pagination, or rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise (a few sentences) and front-loaded with the core purpose. However, it uses untranslated Chinese terms (e.g., 领涨, 单级) which may reduce clarity for non-Chinese-speaking agents. Still, it efficiently conveys key information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The complexity is moderate with 4 string parameters and no output schema. The description includes the return items structure but omits explanations of the fields (e.g., 'chg', 'lists[]'). It also does not clarify '单级' vs '多层' sorting behavior. Adequate but with gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, providing baseline 3. The description adds value by explaining indicator numeric codes as Chinese descriptive labels and clarifying sort_type values (单级/多层). It also specifies default behavior for limit ('returns all'), which goes beyond schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it returns an industry ranking list by market and indicator, with specific indicator values described. It also mentions related tool industry_peers, but does not clearly differentiate from other industry-related sibling tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage by specifying market, indicator, and sort type, but provides no explicit guidance on when to use this tool vs. alternatives like industry_peers or industry_valuation. The mention of passing counter_id to industry_peers hints at a follow-up, but no when-not-to-use criteria.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare the tool as read-only, idempotent, and non-destructive. The description adds no further behavioral context, but the bar is lower due to annotation coverage.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that front-loads the key action and object, with no unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    While the output schema likely details the return values, the description does not explain what 'valuation comparison' entails (e.g., metrics like P/E, P/B). It is adequate but could be more informative.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a clear parameter description. The description does not add any additional meaning beyond the schema, so baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb 'Get' and identifies the resource 'industry valuation comparison for peers', clearly distinguishing it from sibling tools like 'valuation' or 'industry_rank'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as 'valuation_comparison' or 'industry_valuation_dist', leaving the agent to infer the appropriate context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and destructiveHint=false, so the description's statement 'Get daily historical option stats' is consistent. It adds the return fields but no further behavioral details (e.g., data range, rate limits). For a tool with rich annotations, this is adequate but not enhanced.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that clearly states the purpose and lists the return fields. Every word is meaningful and there is no redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description includes the return structure (items with fields), which is helpful given no output schema. However, it omits details like how far back data goes, default date range, or any usage constraints beyond the schema's note about US stocks only. Adequate but not fully comprehensive.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for both parameters ('symbol' and 'count'). The description does not add extra meaning beyond the schema, so baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get', the resource 'daily historical option stats', and the scope 'for a US stock'. It lists the returned fields, making the tool's purpose unmistakable. This distinguishes it from siblings like 'option_volume' or 'option_quote'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives. There are many sibling tools (e.g., 'option_volume', 'option_chain_info_by_date') but no comparison or exclusion criteria provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate read-only, idempotent, non-destructive. Description adds output format but no further behavioral details (e.g., rate limits, auth). Consistent with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, front-loaded with verb, no fluff. Each sentence adds value: action/resource and output structure.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Defines output structure partially compensating for missing output schema. Does not mention default period or count behavior, but otherwise adequate for a simple data retrieval tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema covers 100% of parameters with descriptions. Tool description adds no additional parameter semantics beyond what schema provides. Baseline score of 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states it gets A/H share premium historical K-line data and defines the output structure. Distinguishes from sibling 'ah_premium_intraday' by specifying historical vs. likely intraday.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives like ah_premium_intraday. Lacks context on prerequisites or typical use cases.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds no behavioral context beyond what annotations provide, so it neither enhances nor contradicts them.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, clear sentence with no unnecessary words. It is front-loaded with the main action and resource.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity and the presence of annotations and output schema, the description is mostly adequate. It could mention the output format or edge cases, but it is sufficient for a straightforward check tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a clear description for the single parameter. The tool description does not add extra meaning beyond the schema, so baseline score applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool checks symbol support for DCA recurring investment. It uses a specific verb 'check' and resource 'symbols', and distinguishes it from sibling DCA tools like dca_create, dca_list, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus other DCA-related tools (e.g., dca_list, dca_stats). It does not mention prerequisites, alternatives, or context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and destructiveHint false. The description adds only category definitions and no additional behavioral context (e.g., data recency, rate limits, timezone handling), so it adds minimal value beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise: two short sentences. The first sentence states the core purpose, and the second provides essential category details. No extraneous information; every sentence earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's low complexity, 4 required parameters, and the presence of an output schema and comprehensive annotations, the description is largely complete. It could briefly note that it aggregates across multiple event categories (unlike sibling single-category tools), but this is not required for basic usage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so baseline is 3. The description lists categories but does not add significant meaning beyond the schema's detailed parameter descriptions (e.g., enum values for market). No additional syntax or constraints are provided.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description states 'Get finance calendar events by category and date range' with clear category breakdown. It is specific about the resource and action but does not explicitly differentiate from sibling tools like ipo_calendar or dividend, which serve similar purposes for single categories.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage with category and date range but provides no guidance on when to use this tool versus sibling tools like macrodata or ipo_calendar. No when-not-to-use or alternative recommendations are given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations provide readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, but the description adds no further behavioral details such as data freshness, pagination, or definition of 'holding'. With rich annotations, the description adds minimal value.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with clear verb-first structure. No extraneous words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple nature (1 param, rich annotations, output schema exists), the description is largely complete. Could mention that it returns a list of fund/ETF identifiers, but not necessary with output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The only parameter (symbol) is fully described in the input schema with an example. The tool description adds no additional meaning, so baseline score applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states that the tool retrieves funds and ETFs holding a given symbol. The verb 'Get' and specific resource 'funds and ETFs that hold a given symbol' make the purpose unambiguous and distinct from sibling tools like 'fund_positions'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for finding holders of a symbol but does not explicitly state when to use this tool vs alternatives like 'fund_positions' or provide context about limitations or prerequisites.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare destructiveHint=true and idempotentHint=true, so the risk profile is known. The description adds no extra behavioral context (e.g., what happens to the order, whether it is reversible) beyond restating the action of cancellation. It does not contradict annotations but also does not enrich them.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, compact sentence that immediately states the action and required input. Every word is necessary, with no filler or repetition.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple one-parameter tool, the description, schema, and annotations together provide sufficient context. The description could mention side effects (e.g., immediate termination, cannot be resumed), but the idempotent and destructive hints already cover risk behavior, making the tool adequately specified.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with order_id described as 'Grid order ID.' The description only repeats 'by order_id' without adding syntax, format, or additional meaning. Baseline of 3 is appropriate because the schema fully documents the parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('Cancel') and resource ('grid order') with the identifier ('by order_id'). It clearly distinguishes from sibling tools like 'cancel_order' (for regular orders) and 'grid_suspend' (pause), making the tool's purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no explicit guidance on when to use this tool versus alternatives (e.g., 'use for grid orders, not regular orders'). Usage is only implied by the tool name and context of sibling names, but the description itself does not clarify conditions or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations include destructiveHint=true, idempotentHint=true, and openWorldHint=true. The description does not contradict these, and it adds value by stating that the operation overwrites the entire existing rule, which is critical behavioral detail not fully captured by annotations. No contradictions found.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise, two sentences, and front-loads the core purpose and key behavior (overwrites entire rule). No fluff, every word adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite lacking an output schema, the description is adequate for a mutation tool with a clear effect (replacing a rule). It does not explain return values or side effects (e.g., whether old rule is deleted), but the key behavior is covered. For a complex tool with 23 parameters, it could benefit from noting that all fields are optional except order_id and how omitted fields are treated.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters2/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% for all 23 parameters, so the description does not add much beyond the schema. However, it does note that it accepts the same fields as grid_submit, which helps an agent understand parameter reuse. But it does not compensate for the low description coverage on parameter usage specifics (e.g., which fields are required for a valid replacement).

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool replaces an existing grid order's rule by order_id, and that it overwrites the entire rule. However, it does not explicitly differentiate from sibling tools like grid_submit, grid_cancel, or grid_update, though the phrase 'overwrites the entire rule' hints at a key distinction.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for replacing an existing grid order, but it does not explicitly state when to use this over grid_submit (e.g., for modifications) or when not to use it. No alternatives or exclusions are mentioned, so guidance is only implied.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, covering safety and idempotency. The description adds that the tool returns historical data including target prices, which aligns with annotations. No contradictions; the added behavioral context is minimal but sufficient with the existing annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that directly states the tool's function without any redundant or extraneous information. It is front-loaded and efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's low complexity (one parameter, output schema present, strong annotations), the description is sufficiently complete. It could optionally mention time range limitations or result size, but that is not essential due to the output schema coverage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with one parameter ('symbol') fully described. The description does not add any additional meaning beyond the schema, such as format constraints or examples. Baseline score of 3 is appropriate as the schema already carries the informational load.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb 'Get' and clearly states the resource: 'detailed historical institution ratings and target price history'. This distinguishes it from sibling tools like 'institution_rating' (likely simpler) and 'institution_rating_history' (possibly less detailed), making the purpose unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide any guidance on when to use this tool versus alternatives such as 'institution_rating' or 'institution_rating_history'. There are no exclusions, prerequisites, or contextual hints for an AI agent to decide between them.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and destructiveHint=false, confirming it is a safe read operation. The description adds 'Paginated', which is a behavioral trait not covered by annotations. However, other aspects like error handling or rate limits are not disclosed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise, consisting of two short sentences that immediately convey the core functionality. Every word is necessary, and the structure is front-loaded without any fluff.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of annotations, a full input schema, and an output schema, the description is mostly complete. It explains the tool's purpose and pagination, but could be slightly more explicit about the ranking order or what constitutes 'in the same industry'.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with clear descriptions for all three parameters (page, size, symbol). The description does not add any additional meaning or constraints beyond what the schema provides, aligning with the baseline of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'get' and the resource 'peers ranked by institution analyst ratings in the same industry'. It distinguishes itself from sibling tools like 'industry_peers' and 'institution_rating' by combining both concepts, and mentions pagination.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide any guidance on when to use this tool versus alternatives such as 'industry_peers' or 'institution_rating'. No exclusions or context for selection are given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate read-only, idempotent, safe behavior. The description adds context about real-time data and return fields, but no additional behavioral traits like data freshness or limitations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, efficiently structured with key information front-loaded. Every word contributes value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one parameter, no output schema), the description adequately explains what it returns. Could mention time zone or data source, but sufficient for a straightforward stat retrieval.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a single fully described parameter. The description does not add meaning beyond the schema; baseline 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it provides real-time option call/put volume stats for a US stock, listing specific return fields. It distinguishes from sibling tools like option_quote and option_chain but does not explicitly differentiate from option_volume_daily.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for retrieving option volume data but offers no guidance on when to use this tool over alternatives like option_volume_daily or related chain tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds no new behavioral context (e.g., rate limits, auth requirements, or side effects) but does not contradict the annotations. It is consistent but minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, direct sentence that front-loads the verb and immediately conveys the purpose. There is no fluff or redundancy; every word contributes to understanding.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read-only tool with one optional parameter and a rich set of annotations, the description, schema, and output schema collectively provide sufficient information. The description lacks explicit criteria for 'popularity' but the overall context for a straightforward integer parameter tool is complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has one parameter, 'count', with a clear description and default value. Schema description coverage is 100%, so the tool description adds nothing beyond what the schema already provides. The baseline of 3 applies as the description does not need to compensate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get') and the resource ('popular/trending community sharelists'), distinguishing it from other sharelist tools like sharelist_list or sharelist_detail by specifying 'community' and 'popular/trending'. This provides a specific purpose with a clear differentiation from siblings.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool vs. alternatives. The description does not mention related tools or context (e.g., 'for your own lists, use sharelist_list'), leaving the agent to infer usage. There is no exclusion or alternative reference.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. The description adds the max 1000 constraint but otherwise does not significantly expand on behavior beyond what annotations provide.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with purpose, constraints, and return structure front-loaded. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description enumerates return fields (price, volume, timestamp, trade_type, direction), providing necessary context. However, it omits explanations of field semantics or edge cases.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for both parameters. The tool description does not add new semantic information about the parameters beyond the schema. Baseline of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves recent trades for a symbol, specifying the maximum count (1000) and the returned fields. It distinguishes from many sibling trading data tools by focusing on raw recent trades.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives like trade_stats or history_executions. The description provides no context for selection among many similar data retrieval tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, destructiveHint=false, so the description adds minimal behavioral context. It says 'detailed' but does not elaborate on data frequency, pagination, or other behavioral traits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no extraneous words. Every word contributes to clarity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite having an output schema, the description could hint at the types of valuation metrics included. However, given the schema and annotations, it is adequately complete for selection.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, meaning the schema fully documents the single parameter 'symbol'. The description adds no extra meaning beyond what the schema provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('Get') and resource ('valuation history time series'), clearly distinguishing it from siblings like 'valuation' (snapshot) and 'valuation_comparison' (comparison).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives like 'valuation' or 'valuation_history'. The description lacks usage context or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare idempotentHint=true and destructiveHint=false, so the description need not repeat that. The description adds that the tool enables a price alert, which is consistent. It does not provide extra behavioral details beyond what annotations cover, but does not contradict them.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise: two sentences with no extraneous information. It front-loads the core action and then provides a useful pointer. Every sentence adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with one parameter and an output schema (context indicates has output schema), the description covers the essential purpose and input sourcing. It does not mention prerequisites like whether the alert must exist or be disabled, but given annotations (idempotent, not destructive) and the tool's simplicity, it is sufficiently complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% for the single parameter alert_id. The description adds meaning beyond the schema's 'Alert indicator id' by stating that the alert_id is numeric and how to obtain it via alert_list. This helps the agent understand the parameter's nature and source.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Enable') and the resource ('a price alert by alert_id'). It provides a specific verb and resource. However, it does not explicitly differentiate from siblings like alert_disable, though the action itself distinguishes it. The mention of alert_list helps contextualize the input.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description gives a clear prerequisite: 'Use alert_list to find the numeric alert_id.' This is helpful but lacks guidance on when to use this tool versus alternatives like alert_disable or when not to use it (e.g., if alert is already enabled). No explicit when/why is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare the tool as read-only, idempotent, and non-destructive. The description adds meaningful behavioral context by warning that responses for US accounts querying .US symbols will not match the output schema, which is valuable for an agent to anticipate.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise and front-loaded. The first sentence states the core purpose, and the second sentence adds a valuable edge-case warning without unnecessary wording.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read-only tool with one well-documented parameter and an output schema, the description covers the main function and the notable exception. No significant gaps remain given the structured annotations and schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema covers the single parameter 'symbol' with a description and example, so the description need not add much. The description does not provide additional parameter semantics beyond what the schema already offers, which is acceptable at the baseline.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the function as 'Get company overview' with a specific verb and resource. However, it does not explicitly differentiate this tool from sibling tools like static_info or quote, aside from the implied subject matter.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives. It only mentions a special case for US accounts querying .US symbols, but does not clarify broader scenarios or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true. The description adds that data is minute-by-minute and explains trade session options, but does not disclose any additional traits like data limits or return format.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two efficient sentences: the first states the core purpose, the second explains the key parameter. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    No output schema exists, yet the description does not explain the return structure (e.g., fields like price, volume, timestamp). For a data retrieval tool, this is a gap. Adequate but not complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with both parameters described. The description reiterates the trade_sessions parameter, adding minimal context (default vs all). Baseline 3 since schema does the heavy lifting.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool gets intraday minute-by-minute price/volume data, with a specific verb ('Get') and resource. It distinguishes from siblings like candlesticks or quote by specifying granularity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explains the trade_sessions parameter and its options, but does not explicitly state when to use this tool vs alternatives (e.g., candlesticks for different intervals). No guidance on exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is clear. The description adds the market scope (HK+US) and the 'recently listed' aspect, but no further behavioral traits like pagination or ordering are disclosed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single, front-loaded sentence that conveys all essential information without extraneous words. Every part is earned.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple list tool with two parameters and an output schema, the description adequately covers the purpose and scope. No further details are necessary given the supporting structured data.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with clear descriptions for page and size parameters. The description adds no additional parameter information, so the baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool lists recently listed IPO stocks, specifying markets (HK+US), which distinguishes it from siblings like ipo_calendar (upcoming) and ipo_detail (individual IPOs).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives such as ipo_calendar or ipo_detail. The description implies usage for recent listings but lacks explicit when-not or comparison context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior2/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and destructiveHint=false, indicating safe read operations. The description adds minimal behavioral context beyond repeating parameter defaults. It does not disclose potential constraints or side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, well-structured sentence that lists the core purpose and all parameters efficiently. No extraneous words; it is front-loaded and easy to parse.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (4 parameters, output schema exists), the description covers the essential information. However, it lacks explicit mention of pagination behavior or result set characteristics, which could be beneficial for an agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the schema already documents all parameters. The description adds value by explicitly stating default values for page (1) and count (50) and specifying the default category 'Overnight', enhancing clarity beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves a security list for a market, with explicit supported markets (US, HK, CN, SG) and parameter details. It is specific and distinguishes from siblings as no other sibling tool offers the same functionality.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide guidance on when to use this tool versus alternatives, nor does it mention any exclusions or prerequisites. It only describes what it does, leaving the agent to infer context from sibling names.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate readOnlyHint=false, idempotentHint=false, and destructiveHint=false. The description adds minimal extra context beyond noting it's a 'community' sharelist. It doesn't disclose potential side effects, authentication requirements, or other behavioral nuances, but given the annotations cover the basic safety profile, the description's additional value is limited.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, concise sentence that directly states the tool's function without redundancy. Every word earns its place, and it is appropriately front-loaded with the core action.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple creation tool with an output schema present and full parameter coverage, the description is sufficient. It lacks detailed examples or edge cases, but given the simplicity and available structured metadata, it does not need more. The absence of any mention of the return value is fine because the output schema exists.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema covers 100% of parameters with descriptions, so the baseline is 3. The description adds a brief mention of 'name and optional description,' which aligns with the schema. However, it does not mention the defaulting behavior for description, which is in the schema but not in the description. This is a minor gap, justifying a 4 rather than 5.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (create) and the resource (community sharelist), making the tool's purpose unambiguous. However, it does not explicitly differentiate from sibling tools like sharelist_add or sharelist_delete, although the name strongly implies creation. Slight deduction for missing explicit sibling distinction.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies when to use this tool (when creating a new sharelist) but provides no explicit guidance on when not to use it or mention alternatives. Given the sibling set includes sharelist_delete, sharelist_add, etc., the usage context is obvious from the name but not articulated in the description.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, covering safety. The description adds value by noting that US accounts receive an extra 'us_asset_overview' field, which is a behavioral trait. However, it does not elaborate on other aspects like rate limits or authentication, keeping the score at 3.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at two sentences, with the core purpose in the first sentence and a key detail in the second. Every word earns its place, and it is front-loaded, earning a top score.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read-only tool with no parameters and an existing output schema, the description covers the main functionality and a special case (US accounts). It does not mention limitations like market-specific availability, but overall it is adequate and complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has zero parameters, so schema description coverage is 100% and no parameter explanation is needed. Per guidelines, a baseline of 4 applies for zero parameters, and the description does not detract from this.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it retrieves current stock positions across all channels, using the verb 'Get' and specifying the resource. While it distinguishes from sibling tools like 'short_positions' implicitly, it does not explicitly differentiate or contrast, preventing a score of 5.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for obtaining stock positions but provides no explicit guidance on when to use this tool versus alternatives like 'short_positions' or 'fund_positions'. There are no when-not or exclusion criteria, resulting in a score of 3.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnly and idempotent. The description adds that the server auto-selects industry peers and that comparison_symbols is pending backend support. This provides useful behavioral context beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two short, front-loaded sentences with no wasted words. Efficiently communicates the core idea.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness2/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description is incomplete: it only describes Mode A, ignoring Mode B with comparison_symbols. Given the tool has a pending parameter and two modes, the description should cover both for completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, providing baseline 3. The description adds meaning by explaining that passing only symbol triggers auto-selection of peers, and notes pending support for comparison_symbols. This clarifies parameter behavior beyond schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Stock valuation comparison' and specifies Mode A behavior (single symbol returns stock + peers). However, it omits Mode B involving comparison_symbols, which reduces clarity about full functionality.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description gives minimal guidance on when to use this tool versus siblings like valuation or industry_valuation. It hints at two modes but doesn't explicitly state when to pass only symbol vs. comparison_symbols.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare read-only, idempotent, non-destructive behavior. The description adds value by listing the exact fields returned (symbol, name, last_done, etc.), which is not in the structured annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences: one for purpose, one for return fields. No wasted words, front-loaded with key action.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description does not mention pagination, limits, or behavior when no results found. However, with high schema coverage and clear return fields, it is minimally adequate but could be more complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the schema already documents all parameters. The description does not add additional meaning beyond the schema, so baseline 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool returns a filtered warrant list for a given underlying symbol, with specific return fields listed. This distinguishes it from siblings like warrant_issuers or warrant_quote.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool versus alternatives (e.g., option_chain tools or warrant_issuers). The description only states what it does, not when it's appropriate.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the description adds no extra behavioral context. It does not contradict the annotations, but it also does not elaborate on traits like empty list behavior or rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no extraneous information. It is front-loaded and efficiently conveys the tool's function.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool is simple with no parameters and an output schema present. The description is sufficient for basic understanding, though it could mention that the output is a list of alert objects. Given the output schema, this is a minor gap.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The tool has zero parameters, and schema coverage is 100%. Per guidelines, baseline is 4. The description adds no parameter details, which is acceptable given no parameters exist.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'all configured price alerts', making the tool's purpose unambiguous. It differentiates from sibling tools like alert_add and alert_delete.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides no guidance on when to use this tool versus alternatives, such as when to list versus add or delete alerts. No context about appropriate situations or exclusions is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare safety and idempotency. Description adds context about data source and daily frequency, but does not disclose additional behavioral traits like rate limits or pagination. Baseline 3 since annotations cover core safety profile.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, front-loaded with action and scope. No superfluous words. Efficient and clear.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given output schema exists to document return values, and annotations cover safety, the description is adequate. It specifies source and scope, though date range or history depth is missing. Still fairly complete for a data retrieval tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so both parameters are already documented. Description restates purpose but does not add new meaning beyond schema (e.g., format or constraints). Baseline 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states it retrieves daily holding history for a specific broker and symbol, with explicit scope (HK stocks) and data source (HKEX CCASS). Distinguishes from siblings like broker_holding and broker_holding_detail.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Implied usage for HK stocks only, but no explicit guidance on when to use this tool vs. alternatives (e.g., broker_holding, broker_holding_detail). No when-not or exclusion criteria provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. The description adds historical context but no additional behavioral traits beyond what annotations cover.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 8 words, front-loaded with key information, and contains no superfluous content.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the low complexity, 3 parameters, and presence of output schema and annotations, the description is adequate but lacks differentiation from sibling tools like 'business_segments'.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for all parameters. The description mentions 'period' and 'category' which map to 'report' and 'cate', but adds no extra meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'get' and the resource 'historical business segment revenue trends', and specifies grouping 'by period and category'. It effectively distinguishes from the sibling 'business_segments' which implies current data.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit when-to-use or when-not-to-use guidance is provided. The description implies historical context, but does not mention alternatives or exclusions relative to sibling tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description goes beyond the annotations by disclosing the exact success return ('plain text "order cancelled"') and error conditions (already filled/cancelled). This is extremely valuable for the agent to anticipate outcomes and is not present in the structured annotations. A 5 would require even more context, like rate limits or prerequisites, but this is already very transparent.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a model of conciseness: two sentences that cover purpose, success output, and error conditions without an unnecessary word. Every phrase earns its place, and it's easily scannable by an agent.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with one parameter and no output schema, the description covers the essential contract: what it does, what it returns on success, and when it fails. It could potentially mention the behavior for a non-existent order ID, but given the sibling set (submit_order, replace_order) and the annotations (idempotent, destructive), this is complete enough for an agent to operate correctly.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema already documents the 'order_id' parameter with 100% coverage, including a helpful description. The tool's description doesn't add any parameter-specific information, but per the rubric, baseline 3 is acceptable since the schema covers it. No extra semantic value is added, so a 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's function: 'Cancel an open order by order_id.' This is a specific verb+resource combination that leaves no ambiguity. While it's obvious within the order-management context, it doesn't explicitly differentiate itself from siblings like 'replace_order' or 'submit_order', hence a 4 rather than a 5.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The phrase 'open order' indicates when to use it, and the error message specifies that it fails for filled/cancelled orders, implying these are cases to avoid. However, it doesn't explicitly state alternatives or provide structured when-to-use/not-to-use guidance. The usage context is inferred but clear enough for a 3.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Beyond annotations (readOnly, idempotent), the description discloses a critical behavioral trait: the response may not match the output schema for US accounts querying .US symbols, adding valuable context for the agent.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences with no wasted words: the first states the core function, the second addresses a critical edge case. Front-loaded and efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description covers purpose, response shape inconsistency, and references the output schema. It lacks elaboration on what 'consensus estimates' includes (e.g., metrics, timeframes), but the output schema likely fills that gap.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The single parameter 'symbol' is fully described in the schema. The description adds no new meaning about the parameter itself, but it does tie symbol usage to response shape, which is a behavioral nuance rather than semantic expansion.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it retrieves financial consensus estimates for upcoming periods. However, it does not distinguish from similar sibling tools like forecast_eps or institutional_views, so it lacks explicit differentiation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for fetching consensus estimates but provides no guidance on when to use this tool versus alternatives. It notes a response shape difference for US accounts with .US symbols but does not suggest exclusions or preferred scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate readOnly, idempotent, and non-destructive behavior. The description adds the limit of 10 price levels, which is valuable beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that is concise, front-loaded, and contains no superfluous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple input schema and existence of an output schema, the description is mostly complete, though it could clarify that depth includes bid/ask levels for completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema describes the sole parameter 'symbol' with examples, achieving 100% coverage. The tool description adds no extra parameter information, so baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves 'order book depth for a symbol' with a limit of 10 price levels, which is specific and distinguishes it from siblings like quote or candlesticks.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as quote or market_temperature; the description only explains what it does.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, destructiveHint, idempotentHint, and openWorldHint. The description adds the output structure and specific currencies, which is helpful but does not provide additional behavioral details such as update frequency or rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise, two sentences, front-loaded with the key action. Every sentence adds value, specifying the output structure and example currencies with no wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple, parameterless tool, the description adequately covers the purpose and output. It mentions the output format and sample currencies, which is sufficient. It could list all currencies for completeness, but the given level is satisfactory.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With zero parameters and 100% schema coverage, the description does not need to add parameter semantics. It correctly omits param details but does not provide extra information beyond the schema, meeting the baseline for high schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves exchange rates for all supported currencies, listing specific currencies and the output format. It is distinguishable from sibling tools, none of which directly cover exchange rates.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when exchange rates are needed, but provides no explicit guidance on when to use this tool versus alternatives or when not to use it. Given the tool's simplicity, the lack of alternatives is acceptable but still missing explicit context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already provide readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, covering safety and behavior. The description adds no extra context beyond the name, but does not contradict annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single, concise sentence with no wasted words. It is appropriately sized for a simple read-only tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of an output schema and comprehensive annotations, the description is minimally complete. It could be enriched with more detail about what fund positions include, but is sufficient for a straightforward retrieval tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    No parameters exist (0 params, 100% schema coverage). The description does not need to explain parameters. Baseline for zero params is 4.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves current fund positions. It uses a specific verb ('Get') and resource ('current fund positions'), distinguishing it from sibling tools that handle different data types.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives. The description does not mention exclusions, prerequisites, or context for its use.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Given the annotations already declare readOnlyHint and openWorldHint, the description adds useful behavioral context by listing response contents (price, quantity, executed price/qty, trigger time) and pagination support. This goes beyond the annotations without contradicting them. No destructive or mutation behavior is implied, matching the read-only annotation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences long and immediately states the purpose. It is front-loaded, specific, and contains no filler. Each clause conveys useful information: the resource, response fields, and pagination.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Considering the presence of an output schema, read-only annotations, and only three simple parameters, the description provides adequate context for agent invocation. It clearly identifies the one required parameter context and the nature of the returned data. Additional nuance about alternative tools or default behaviors is available via the existing schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so order_id, page, and limit are already documented with defaults and purpose. The description reinforces that order_id is the grid order to fetch and that page/limit are supported, but it does not add new parameter-level detail beyond the schema. This matches the baseline for full schema coverage.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description identifies the resource as 'trigger history for one grid order' and specifies that it contains child order details like price, quantity, executed price/qty, and trigger time. This scope clearly distinguishes it from list-level grid tools such as grid_list or grid_detail. It lacks an explicit verb but the intended action is unambiguous.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies when to use this tool: when needing the triggered child orders for a specific grid order. It also mentions pagination via page/limit. However, it does not explicitly state alternatives or when not to use it, relying instead on the general context among grid-related siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and not destructive. The description adds no extra behavioral context (e.g., no mention of authentication, rate limits, or output structure). It does not contradict annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence of 13 words, immediately conveying the tool's purpose and primary input. Every word is essential, with no fluff or redundancy.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple retrieval tool with one parameter, annotations covering safety, and an existing output schema, the description is sufficiently complete. It could optionally note that the order_id must come from ipo_orders, but this is not required for correct usage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and the description of 'order_id' as 'IPO order ID' mirrors the schema property description. No additional meaning, format, or examples are provided beyond what the schema already gives. Baseline 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Show detailed information'), the resource ('a specific IPO order'), and the identifier ('by order_id'). It distinguishes from sibling tools like ipo_orders (which lists orders) and order_detail (for regular orders) through the specific mention of IPO orders.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when you have an order_id for an IPO order, but lacks explicit guidance on when to use this tool over alternatives (e.g., ipo_orders for listing, order_detail for non-IPO orders). No when-not-to-use or prerequisites are stated.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, destructiveHint. Description adds market scope and stage, but does not disclose any additional behavioral traits like pagination or output limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, front-loaded with the verb 'List', no unnecessary words. Efficient and to the point.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Low complexity tool with no parameters and presence of output schema. Description covers purpose and scope but could mention output format or return details for completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Input schema has zero parameters, so schema coverage is 100%. No parameters to explain, so baseline 4 is appropriate. Description does not need to add parameter info.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states verb 'List', resource 'IPO stocks', and specifies stage ('subscription/pre-filing') and markets ('HK+US'). Distinguishes from sibling tools like ipo_calendar, ipo_detail, ipo_listed.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool over alternatives. Does not mention exclusions or provide context for selection among sibling IPO tools.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate read-only, open-world, idempotent, and non-destructive behavior. The description adds the return structure but does not provide additional behavioral context such as pagination or rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence plus a compact return type snippet, front-loading the action and providing essential information with no extraneous text.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read-only tool with one parameter, the description covers the purpose and return format adequately. It could mention if there are any limits on the number of articles, but the schema annotations handle safety and idempotency.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema fully describes the single parameter 'symbol' with an example. The description does not add further semantics beyond what is in the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves latest news articles for a symbol, and lists the exact return structure (items array with fields). This distinguishes it from sibling 'news_search' which likely searches news by keyword.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides a clear use case (news for a symbol) but does not explicitly advise when to use this tool over alternatives like 'news_search' or other data-fetching tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds value by specifying the exact return fields, which annotations do not cover. However, no additional behavioral traits (e.g., rate limits, caching) are disclosed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with structured list of return fields. Extremely concise with no redundancy, front-loading the core action.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read tool with one parameter, the combination of schema, annotations, and description is nearly complete. Missing details like timestamp format are minor; otherwise sufficient for selection and invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% (parameter 'symbols' is fully described with examples). The description does not add parameter information beyond the schema; it only describes output. Baseline score of 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description states 'Get latest price quotes' with a specific verb and resource, and lists exact return fields per symbol. This clearly distinguishes it from siblings like candlesticks or intraday which provide different time frames or data granularity.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance on when to use this tool vs alternatives (e.g., 'now' for a single snapshot, 'intraday' for intraday data). The description only states what it does, not when to prefer it.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description discloses the return message and the order status requirement. Annotations already provide destructiveHint and idempotentHint. This adds some context beyond annotations, but does not cover failure cases or side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences, front-loaded with the action and resource. Every sentence serves a purpose with no extraneous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a mutation tool with no output schema, the description covers the action, parameters, return value, and a constraint. It is fairly complete, though missing error handling details.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with each parameter described. The description groups parameters (quantity, price, etc.) but does not add meaning beyond what the schema already provides. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool modifies open orders and lists specific parameters (quantity, price, trigger_price, trailing params). It implicitly distinguishes from siblings like cancel_order and submit_order by stating 'modify' and restricting to open/pending orders.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides context by noting that only open/pending orders can be modified, but does not explicitly state when to use this tool versus canceling and resubmitting. It offers implied guidance without direct exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows it is a safe read. The description adds the accepted market values and the chaining contract, but since an output schema exists, the lack of return-shape detail is acceptable. Still, no extra behavioral traits (e.g., result limits) are disclosed.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Three terse sentences with zero filler: one for the core purpose, one for the parameter format with default, and one for the next step. Every sentence earns its place and the structure front-loads the most important information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a single-parameter, read-only listing tool with an output schema, the description covers the purpose, the market parameter, and the crucial follow-up chaining to screener_search and screener_strategy that a consumer would need to build a full workflow.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    With 100% schema description coverage for the single optional market parameter, the baseline is 3. The description restates the same market format and default as the schema, so it adds little beyond what structured data already provides at the parameter level.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    "List platform-preset screener strategies" uses a specific verb (list) with a well-scoped resource (platform-preset strategies). The qualifier "platform-preset" explicitly differentiates this from the sibling screener_user_strategies, and the chaining note distances it from screener_search and screener_strategy.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Useful downstream context is given (pass id to screener_search strategy_id to run, or screener_strategy to inspect filters), which implies what to do with the output. However, it never explicitly states when to use this vs. alternatives such as screener_user_strategies — the contrast is only implied by the word "platform-preset."

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description does not contradict the read-only and idempotent annotations. It adds context about auto-running saved strategies, but does not disclose additional side effects or error conditions beyond what annotations already cover.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness3/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is structured with a clear opening and mode explanations, but it repeats much of the schema's parameter details, making it somewhat verbose. It could be more concise by referencing the schema directly.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's complexity with two modes, the description covers the necessary usage scenarios and cross-references. The presence of an output schema means detailed return values are not needed. It is sufficiently complete for practical use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema descriptions for all parameters are already detailed, covering market modes, condition keys, and technical indicator formats. The tool description largely duplicates this information without adding new semantic meaning.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Screen stocks' and distinguishes two modes (A and B), making its purpose specific. It references related tools for strategies and indicators, reinforcing its role as a screening tool.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    It explicitly mentions Mode A for strategy-based screening and Mode B for direct filter conditions. It points to screener_recommend_strategies for strategy IDs and screener_indicators for technical indicator schema, providing clear guidance on when to use this tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds no further behavioral details (e.g., error responses, permissions) which is acceptable given the annotations are robust, but it does not disclose anything beyond them.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    A single, clear sentence that conveys the operation without fluff. Every word earns its place; perfectly sized for a simple tool.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With an output schema present ara and complete annotations, the description is sufficient. It covers the single required parameter and the action. Slight deduction: no mention of the source 'community' aspect being important for disambiguation, but overall complete for a simple retrieval tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a single parameter 'id' described as 'Sharelist ID'. The description repeats this without adding new meaning—no format, type hints, or constraints beyond schema. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb 'Get' with the resource 'community sharelist detail' and parameter 'by id', clearly distinguishing it from sibling tools like sharelist_create or sharelist_delete. It precisely states what the tool does.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for retrieving a specific sharelist but provides no explicit when-to-use or when-not-to-use guidance. No alternatives are mentioned, though the action is so specific that context is reasonably clear from the name and siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, fully covering the behavioral safety profile. The description adds the cross-tool link to 'statement_export' and the notion of statement types, but does not significantly expand on behavior beyond what annotations provide. No contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise at two sentences with no redundant words. The first sentence states the core purpose, and the second sentence provides a crucial usage hint. Every sentence earns its place, making it highly efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description covers the main purpose and connects to a sibling tool, which is important context. It does not detail the output format, but an output schema exists (not shown here but mentioned in context signals). Minor omission: it does not explicitly mention that the returned statements have an 'id' field for export, though it is implied. Overall, sufficient for a simple read-only listing tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, with all three parameters clearly described in the schema (limit, start_date, statement_type). The description only restates the statement_type values ('daily' and 'monthly') without adding new meaning or formatting details. Therefore, it provides no additional value beyond the schema, resulting in a baseline score of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'List available account statements (daily/monthly)' with a specific verb ('List') and resource ('account statements'). It also distinguishes itself from the closely related sibling 'statement_export' by noting that the id obtained here can be used for download, thus differentiating their purposes.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description gives a clear follow-up action ('Use the id with statement_export to download'), implying that listing is a precursor to downloading. However, it does not explicitly state when to use this tool versus other similar listing tools, nor does it mention when not to use it or provide other alternatives. The guidance is implicit and minimal.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate read-only, non-destructive behavior. The description adds value by specifying the return structure (items array with fields), which goes beyond annotations. No contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no wasted words. It is front-loaded with the main action and immediately specifies the return format.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one parameter, no output schema), the description is adequate. It specifies the input and output fields, though it omits details like pagination or limits, which are not critical for this straightforward tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The only parameter 'symbol' is fully described in the schema (100% coverage). The description does not add further meaning, so the baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get discussion topics for a symbol' with a specific verb and resource, and lists the returned fields. It distinguishes itself from sibling tools like topic_create, topic_detail, and topic_replies.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No guidance is provided on when to use this tool versus alternatives such as topic_detail or topic_replies. The description lacks context on when it is appropriate or not.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and destructiveHint=false, so the description does not need to repeat safety. It adds minimal behavioral context (return fields) but lacks details on pagination or ordering. No contradiction with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with no wasted words. Front-loaded purpose followed by return details. Efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple search tool with annotations indicating safety and idempotency, the description covers the essentials (keyword search, return fields). However, it lacks details on result ordering and pagination beyond the limit parameter, which could be useful.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, with both 'keyword' and 'limit' described. The description adds no additional parameter meaning beyond citing return fields. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Search community topics/posts by keyword' with a specific verb and resource. It distinguishes from sibling tools like 'topic_detail' and 'topic_replies' by focusing on keyword search, and mentions return fields (id, author, time, excerpt).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies use for keyword search but provides no explicit guidance on when to use this tool versus alternatives such as 'topic_detail' or 'topic_replies'. No exclusions or context are given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, making the safety profile clear. The description adds no new behavioral context beyond what annotations provide, and does not contradict them. Score 3 is appropriate as description adds minimal value.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence, front-loaded with the action and scope. Every word is necessary; no redundancy or elaboration. Perfectly concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Despite simplicity, the tool is straightforward (3 required params, no nested objects) and annotation coverage is strong. Output schema exists to document return values. The description is sufficient for an agent to invoke correctly, though it could hint at the return format (e.g., list of dates).

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the input schema fully documents all three parameters. The description merely repeats 'market: HK/US/CN/SG' which is already in the schema. No additional semantics or usage details are provided.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'trading days', and specifies the scope as markets (HK/US/CN/SG) and a date range. This uniquely identifies the tool among siblings like trading_session or market_status.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies when to use (to get trading days) but does not provide explicit guidance on when not to use or alternatives. No exclusion or comparison with siblings like trading_session is given.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, destructiveHint=false, etc. Description adds the returned fields but not behavioral details like pagination or side effects.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence with verb upfront, followed by field list. No wasted words; front-loads purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a read-only list tool with two simple parameters and no output schema, description covers what it returns. Missing a note on pagination behavior, but otherwise adequate.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so parameters are already well-documented. Description adds no extra meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states the verb 'list' and resource 'withdrawal history' for the current account, distinguishing it from sibling tools like 'deposits' which list deposits.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit when-to-use or when-not-to-use guidance. The description implies it's for viewing withdrawal history, but offers no alternatives or exclusions compared to other list tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate a write operation (readOnlyHint=false) and not destructive (destructiveHint=false). The description adds that it returns the created alert object, but lacks details on side effects like whether duplicate alerts are allowed or if there are rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Three short sentences, each carrying essential information. No fluff or repetition. The structure is clear: purpose, then parameter options, then return value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    While the description covers basic usage, it lacks information about required parameter formats (e.g., price string format), potential errors, or prerequisites (e.g., symbol must exist). For a 4-parameter tool with no output schema, more context would be beneficial.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, but the description adds value by explaining possible values for 'condition' and 'frequency' with examples (e.g., 'once (trigger once then disable)'). This goes beyond the schema's property descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states the tool adds a price alert, with specific verb 'Add' and resource 'price alert'. The description lists condition and frequency options, distinguishing it from sibling tools like alert_delete, alert_list, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Describes the condition and frequency options, which helps the agent know how to configure the alert. However, it does not explicitly state when to use this tool versus alternatives or when not to use it (e.g., if alerts already exist for the symbol).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations confirm read-only and idempotent behavior; description adds return field details. However, schema includes parameters (us_page, us_limit) labeled for another tool without clarification.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences front-load purpose and then detail return format and required parameters. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Lists return fields but no output schema. Does not address optional parameters or differentiate from sibling 'history_orders' which might be confused with this executions tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema descriptions cover 100% of parameters but contain misleading text for us_page/us_limit. Description adds meaning for required params (RFC3339) but not for optional ones.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states 'Get historical trade executions between dates' and lists return fields. Distinguishes from 'today_executions' sibling by specifying date range.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Describes the function for historical date ranges but does not explicitly exclude or compare to alternatives like 'history_orders' or 'today_executions'.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so safety profile is clear. The description adds 'current' but no further behavioral traits beyond what annotations provide.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence, no wasted words, front-loaded with purpose. Ideal conciseness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given zero parameters, rich annotations, and presence of output schema, the description is complete for this simple tool.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    No parameters exist; schema coverage is 100%. Per rubric, baseline for 0 params is 4. Description adds no parameter detail but none is needed.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool returns current market trading status for all markets, using a specific verb and resource, and distinguishes it from siblings like quote or candlesticks.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines2/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, idempotentHint, openWorldHint, and non-destructive behavior, so the safety profile is well covered. The description adds the temporal 'current' qualifier and market scope, but does not disclose additional behavioral details such as return semantics or potential edge cases. No contradiction with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no filler. Every word carries meaning: the action, the resource, and the allowed market values.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read-only tool with one fully documented parameter, rich annotations, and an output schema, the description is sufficiently complete. It states the tool's purpose and scope, and no critical information is missing for invoking it.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% for the single parameter, so the baseline is 3. The description simply restates the market codes ('HK/US/CN/SG') without adding examples, value constraints, or deeper meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('Get') and resource ('current market sentiment temperature'), and enumerates the supported markets (HK/US/CN/SG). It clearly differentiates from the sibling 'history_market_temperature' via the word 'current'.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies this tool is for current sentiment readings, but it does not explicitly state when to use it versus alternatives like 'history_market_temperature' or 'market_status'. No exclusions or alternative tool references are provided, so usage guidance remains implicit rather than explicit.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already cover read-only and idempotent behavior. The description adds context on return format but does not disclose additional behavioral traits beyond what annotations provide. With strong annotation coverage, a score of 3 is appropriate.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise: two sentences that front-load the purpose and then detail the return format. Every sentence adds value, and there is no fluff.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one parameter, no output schema), the description fully covers what the tool does and what it returns. No additional context is needed for effective agent use.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema already documents the single parameter 'symbol' with a clear description. Schema description coverage is 100%, so the description adds no further parameter detail beyond the schema, justifying a baseline score of 3.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's action ('get trade statistics') and specifies the output fields (buy/sell/neutral volume distribution) with a clear structure. It differentiates from siblings like 'trades' by focusing on aggregated statistics rather than raw trade data.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for obtaining volume distribution but does not explicitly state when to use this tool versus alternatives like 'trades' or other analytical tools. No when-not or alternative guidance is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior. The description adds critical transparency: for US accounts querying a .US symbol, the response shape differs from the output schema. This detail about output variability goes beyond what annotations provide, aiding correct interpretation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise, consisting of two sentences. The first sentence states the core purpose, and the second provides a crucial behavioral caveat. No superfluous words; information is front-loaded and efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple parameter set and the presence of an output schema, the description adequately covers the special output shape discrepancy. It does not need to explain standard return values. The mention of peer comparison adds context. Completeness is high for a tool of this complexity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a clear description for the 'symbol' parameter. The description adds semantic value by linking the parameter value to a behavioral change: different response shapes for .US symbols. This informs the agent about a conditional effect of the parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves a 'valuation overview with peer comparison', providing a specific verb and resource. It differentiates from siblings like 'valuation_comparison' by noting an output shape quirk for US .US symbols, but does not explicitly contrast with all sister tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for obtaining valuation with peer comparison and warns about a special case for US accounts with .US symbols. However, it does not provide explicit when-to-use or when-not-to-use guidance, nor does it mention alternatives among the many sibling tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnly, idempotent, non-destructive. Description adds return structure and filtering context, enhancing transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two concise sentences covering action, return fields, and filtering. No superfluous words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Description provides sufficient context for a simple tool with one optional parameter. Lists return fields, compensating for lack of output schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and description mostly restates schema. No additional meaning beyond what the schema provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states it retrieves account cash balance and asset summary, lists return fields, and mentions filtering by currency. Distinct from sibling tools like broker_holding or stock_positions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use this tool versus alternatives like broker_holding or cash_flow. Usage is implied but not differentiated.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate destructive and idempotent behavior. The description adds that the tool returns the updated plan, but doesn't disclose additional behavioral traits beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two concise sentences that front-load the purpose and key parameter, then detail modifiable fields and values with no extraneous content.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Complete enough given tool simplicity: describes input fields, return (updated plan), and allowed values. Lacks output schema and error handling but sufficient for an update operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, and the description adds value by specifying allowed values for frequency, day_of_week, and day_of_month, though it omits the allow_margin parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool updates an existing DCA plan by plan_id and lists modifiable fields, distinguishing it from sibling tools like dca_create, dca_stop, etc.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Usage is implied by the name and description (update an existing plan), but no explicit guidance on when to use versus alternatives like dca_pause or dca_stop is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate destructiveHint=true. The description adds valuable context about the purge parameter, explaining side effects. No contradictions with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a two-sentence, front-loaded structure with no extraneous information. Every sentence earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple delete tool with a purge flag and an output schema, the description covers core behavior and the purge option. Minor lack of detail on default behavior (securities when purge=false).

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the schema fully documents both parameters. The description adds no additional meaning beyond what the schema provides, meeting the baseline.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Delete a watchlist group by id (numeric)', specifying the verb and resource. It effectively distinguishes from sibling tools like create_watchlist_group and update_watchlist_group.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies use when deleting a watchlist group but provides no explicit guidance on when to use this tool versus alternatives, or any exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate readOnlyHint=false (mutation), idempotentHint=true (safe to retry), and destructiveHint=false (non-destructive). The description adds the context that the order must be suspended, which is a useful constraint, but does not describe what happens on success or any side effects beyond resuming. With annotations covering the safety profile, this is adequate but minimal.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence with no filler: 'Restart (resume) a suspended grid order by order_id.' It front-loads the action and states the prerequisite, making it highly concise and clear.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (one parameter, no output schema) and the annotations covering behavior, the description is complete enough. It could be improved by explaining what happens on success (e.g., the order resumes trading) or error conditions, but for a basic resume action, it's sufficient.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% and the schema already explains order_id as 'Grid order ID.' The description adds no additional meaning or format guidance beyond that, so it falls at the baseline of 3 since the schema does the heavy lifting.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action: restart (resume) a suspended grid order, specifying the target resource (grid order) and the condition (suspended). This distinguishes it from siblings like grid_suspend and grid_cancel by explicitly naming the resume effect.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies the appropriate use case: when a grid order is suspended. It says 'Restart (resume) a suspended grid order,' which tells the agent it should only be used on suspended orders. However, it does not explicitly mention when not to use it (e.g., for active or cancelled orders) or contrast with alternatives like grid_replace, so it's clear but not exhaustive.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Beyond readOnlyHint and idempotentHint annotations, the description discloses the tree structure and data shown per node (stock count, daily change, YTD change), adding useful behavioral context.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, no fluff; front-loaded with purpose immediately, followed by input and output details.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple single-parameter tool, output schema exists, and annotations provide safety profile, the description is sufficiently complete.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema already describes the symbol parameter, but the description adds the origin (from industry_rank) and an example format, enhancing understanding.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose4/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states it provides a hierarchical sub-sector tree for an industry group. Specific verb+resource, but does not explicitly distinguish from sibling tools like industry_rank or industry_valuation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate it's read-only and idempotent. The description adds that it shows a summary and per-stock breakdown, but does not elaborate on pagination behavior or data freshness, which would be helpful.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise: a single sentence plus a note on period. No unnecessary words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With output schema present and annotations, the description is fairly complete. However, it could mention that results are paginated via page and size parameters, which are only in schema.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% and the description adds no additional meaning beyond the schema. It reiterates the period values but no new information.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, indicating safe, read-only behavior. The description adds value by disclosing the return format (list of fields with types) and pagination mechanism, which are behavioral traits not covered by annotations. This is sufficient transparency.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise: two sentences with no unnecessary words. The first sentence states the purpose, and the second provides essential output and pagination details. It is well-structured and efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool has no output schema, the description compensates by listing the return fields and their types (e.g., publish_at in RFC3339) and explaining pagination cursors. This is comprehensive for a search tool. Minor missing details like error handling could be added, but not required for basic usage.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema covers both parameters (keyword and limit) with descriptions, achieving 100% coverage. The description does not add new information about the parameters; it only describes the output. Thus, baseline score of 3 is appropriate as the schema already provides necessary semantics.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, destructiveHint=false. The description adds context about the response structure: 'Technical indicators include a tech_values field showing available options'. This explains behavior beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences: first clearly states the purpose, second elaborates on a key detail (tech_values structure). No unnecessary words, front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given that output schema exists (stated), the description covers the essential aspects: keys, units, default ranges, and tech_values. Slightly lacking in explaining how defaults are defined or if there are limits, but overall sufficient.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a described optional 'symbol' parameter. The description does not mention the parameter, so it adds no value beyond the schema. Baseline 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool returns 'all available screener indicator keys with units and default value ranges', distinguishing it from sibling tools like screener_search or screener_strategy. The verb 'get' and resource 'indicator keys' are specific.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage when a user needs available screener indicators, but it does not explicitly state when to use this tool versus alternatives (e.g., screener_strategy). No exclusion criteria or comparisons are provided.

Since annotations handle the main traits, a score of 3 is appropriate.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single concise sentence that directly communicates the tool's function. There is no extraneous information or repetition.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple nature of the tool, the existing annotations, and the presence of an output schema, the description adequately conveys the purpose and scope. It could mention that it returns an array of sharelists, but the output schema likely covers that. It is complete enough for agent invocation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The only parameter 'count' is fully described in the schema with its default and purpose. The description adds no additional meaning beyond what the schema provides. With 100% schema coverage, the baseline is 3, and the description does not exceed that.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb 'List' with a defined scope: 'user's own and subscribed community sharelists'. This clearly distinguishes from sibling tools like sharelist_popular, which lists popular sharelists, and sharelist_detail for single list details. The purpose is unambiguous and tailored.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description indicates the function lists personal and subscribed sharelists, implying that for community-wide popular lists, one would use a different tool (e.g., sharelist_popular). However, it does not explicitly mention alternatives or provide explicit when-to-use guidance, but the scope definition itself gives clear context.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations provide destructiveHint=true, idempotentHint=true, which align with the description. The description adds context about returning the upstream API response, but does not detail error handling or partial success behavior.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise with two sentences, no unnecessary words, and efficiently conveys the tool's purpose and requirements.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description sufficiently covers the tool's behavior for a simple removal operation, given the required parameters and annotations. It explains the return value and the task.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Both parameters have descriptive schema, and the description adds 'Provide symbols to remove' which is already covered. With 100% schema coverage, the description does not add significant new meaning.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (Remove securities), the resource (community sharelist by id), the required inputs (symbols), and the return value. It distinguishes from sibling tools like sharelist_add and sharelist_create.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for removing securities from a sharelist but does not provide explicit guidance on when to use this tool versus alternatives, nor does it mention prerequisites or exclusion cases.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate non-readonly and destructive nature; the description adds that it returns the upstream API response on success, providing some behavioral context beyond the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences, concise, and front-loaded with the core action. No extraneous information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple mutation tool with full schema coverage and annotations, the description is largely complete. It could mention the return format, but the 'returns upstream API response' provides sufficient context.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the schema already documents both parameters. The description adds minimal extra meaning (e.g., 'by id' and 'desired new order'). Baseline 3 is appropriate.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds the market parameter scope but does not provide additional behavioral context such as return formats or error behavior. Since annotations are strong, the bar is lower, and the description adds minimal extra value, so a 3 is appropriate.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read-only list tool with one optional parameter, the description is complete. The output schema is present (as per context signals), so return value details are covered. The description provides enough context for the agent to know when and how to invoke it, including the market filter and downstream use of the id.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema covers the single parameter 'market' with 100% description coverage, including allowed values and default. The description repeats this information ("market: US|HK|CN|SG (default: US)") without adding any new semantic meaning, such as format, examples, or interplay with other parameters. Since schema does the heavy lifting, the baseline of 3 applies.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the purpose: "List the current user's saved screener strategies." It specifies the resource (user's saved screener strategies) and the operation (list). It also distinguishes from sibling tools like screener_recommend_strategies (recommended vs. user's own) and screener_strategy (inspect conditions vs. list).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides clear context on when to use the tool: to list the user's saved strategies. It also gives guidance on the workflow: "Pass id to screener_search strategy_id to run, or screener_strategy to inspect conditions." This implies downstream usage, but it does not explicitly state when NOT to use it or contrast with alternatives for listing, so it falls slightly short of a 5.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already provide read-only, non-destructive, idempotent, and open-world hints. Description adds the return structure (groups with id, name, securities) but no additional behavioral traits like pagination or authentication needs.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single sentence that efficiently states purpose and return format. No wasted words.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no parameters, comprehensive annotations, and no output schema, the description fully explains what the tool returns. It lists all fields in the response, making it complete for a simple list operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    No parameters exist; schema coverage is 100%. Baseline for zero parameters is 4. Description does not need to add parameter info, but it does document the return structure.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description explicitly states 'Get all watchlist groups and their securities' with a clear verb and resource. It distinguishes from sibling tools like create_watchlist_group, delete_watchlist_group, and update_watchlist_group by being the read-only list operation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit guidance on when to use vs alternatives. However, the context of sibling tools (mutations for individual groups) implies this is for listing all groups, but no exclusions or alternatives are mentioned.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description adds behavioral context beyond the annotations by specifying the data source (HKEX CCASS participant disclosure) and that it returns 'top' holdings. This complements the readOnlyHint and other annotations without contradiction.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, short sentence that conveys all essential information without extraneous text. It is front-loaded with the main action and resource.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of a full schema, annotations, and output schema, the description adequately covers the tool's scope, data source, and limitation to HK stocks. It is complete for a simple data retrieval tool with good structured metadata.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema covers 100% of parameters with descriptions. The description adds general context (HK stocks) but does not describe the period parameter beyond what the schema already provides. Thus, the description adds little semantics over the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action ('Get'), the resource ('top broker holding data'), and the constraint ('for a symbol (HK stocks only)'). It distinguishes from siblings like broker_holding_daily by specifying 'top' and the source (HKEX CCASS).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explicitly limits usage to HK stocks and identifies the data source, providing clear context. However, it does not explicitly mention when not to use or suggest alternative tools for other markets or full holding details.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, idempotentHint=true, etc. The description adds behavioral details about return format and filter syntax, which is sufficient given the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences, front-loaded with the core action, and includes all necessary details without redundancy. Every sentence adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With no output schema, the description explains return fields and filter options. It lacks pagination details but the schema covers that. Adequate for a simple list tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for all four parameters. The description adds clarity by specifying comma-separated formats and an example for currencies, going beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'List deposit history for the current account', using a specific verb and resource. It lists return fields and distinguishes from siblings like account_balance or withdrawals.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not provide explicit guidance on when to use this tool versus alternatives. It implies usage for listing deposit history but lacks comparisons or exclusions.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate read-only, idempotent, non-destructive behavior. The description adds the region-restriction error behavior (DcRegionRestricted), which is valuable context beyond annotations. No contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two brief sentences front-loading the primary action, with no extraneous information. Every word contributes to understanding the tool's purpose and constraints.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the presence of an output schema (not detailed here), description adequately covers purpose, region restriction, and error condition. It could mention document types or ordering, but is sufficient for a simple retrieval tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with descriptions for both 'symbol' and 'limit'. The description does not add any additional parameter meaning beyond what the schema provides, so it meets the baseline but does not exceed it.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it retrieves regulatory/prospectus documents for US ETFs, using specific verb 'Get' and resource 'regulatory/prospectus documents'. It distinguishes from sibling tools like 'filings' by specifying ETF focus and US-only restriction.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explicitly states 'US accounts only' and warns about region restrictions (errors for HK/CN/SG), providing clear context on when to use. It does not explicitly exclude alternatives, but no direct alternative exists among siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Read-only behavior is consistent with annotations; description adds filter details without introducing side effects or contradictions.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Single, clear sentence covering purpose and key filtering/pagination features without unnecessary verbosity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Sufficient for a list operation; output schema exists so return values need not be described. Could mention pagination behavior, but not essential.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema already includes full parameter descriptions with examples; the description repeats these without adding new meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states it lists grid trading orders, distinguishing it from detail or submission tools like grid_detail and grid_submit.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Implies usage for retrieving lists with filters, but does not explicitly contrast with alternatives; adequate for a straightforward listing operation.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The annotations already provide readOnlyHint: true and openWorldHint: true, so the description is not responsible for communicating read-only semantics. The description adds minimal additional behavioral context, but the annotations fully cover the safety profile. A slight mention of no side effects could be added but is redundant here.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, punchy sentence with zero fluff. It is perfectly sized for a simple fetch operation.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a read-only fetch tool with one parameter, clear schema, and annotations, this description is fully adequate. The context signals (no nested objects, no enums, simple array parameter) simplify the need for elaboration. An output schema exists, so not detailing return values is not a gap.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% with a helpful example ('e.g. ["123", "456"]') in the schema itself. The description's focus on 'their IDs' reinforces the purpose of the sole parameter. Since the schema does all the heavy lifting, the description adds adequate value, meeting the baseline for a single-parameter tool.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description 'Fetch specific grid orders by their IDs' uses a specific verb ('Fetch') and names the resource ('grid orders') plus the scoping mechanism ('by their IDs'). This aligns perfectly with the tool name and clearly belongs to the grid order family of tools, distinguishing it from related siblings like 'grid_list' (which likely fetches all).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for fetching specific grid orders, and the tool's place in the grid family is clear from its name and siblings. However, it does not explicitly state when NOT to use it (e.g., for listing all orders) or name a specific alternative tool, missing an opportunity to fully distinguish from siblings like 'grid_list'.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate a non-read-only, idempotent, non-destructive operation. The description adds the business context of a one-time prerequisite, but doesn't disclose additional side effects, response details, or failure modes. It neither contradicts nor significantly extends the annotations, making a 3 appropriate.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two concise sentences with no redundancy. It front-loads the primary action ('Record...') and adds the prerequisite context in the same sentence, followed by a clear parameter note. Every word earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the tool's simplicity (zero parameters, no output schema), the description covers the core purpose and the usage prerequisite. It doesn't mention return values or error handling, but the annotation set (especially idempotentHint) covers behavioral expectations. A small gap is the lack of what occurs if consent already exists, but the idempotent hint mitigates this. Complete enough for a low-complexity tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The tool has zero parameters, and the description explicitly states 'Takes no parameters,' which is consistent with the empty schema. The baseline for zero-parameter tools is 4, and the description confirms this without adding unnecessary noise.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses the specific verb 'Record' with the resource 'one-time grid strategy risk-disclosure consent' and explicitly states the prerequisite context ('required before submitting grid orders'). This clearly distinguishes it from sibling tools like grid_submit, grid_cancel, and grid_replace, which handle order actions.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    It specifies when to use the tool: 'required before submitting grid orders', which implies using it prior to grid_submit. It also notes the 'one-time' nature, giving a clear usage boundary. However, it doesn't explicitly exclude scenarios like when consent already exists, nor does it name alternatives, so it falls just short of a 5.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, idempotentHint, and destructiveHint=false, so the description does not need to restate safety. It adds value by detailing the return format (strikePrices with call/put fields), which gives the agent a clear picture of what to expect beyond the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence that front-loads the purpose and immediately follows with the return structure. Every part is essential; there is no fluff. It is optimally concise for its complexity.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool is simple with only two parameters fully described in the schema, no output schema, but the description provides the return structure. Given the low complexity and annotations, the description is complete enough for an agent to use correctly. It could benefit from clarifying that the date must be an expiration date (not any date), but the schema's date description implies this.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, so the schema fully documents both parameters (symbol and date). The description does not add new parameter information but indirectly provides context by showing the return structure, which helps understand how parameters map to output. This meets the baseline for fully covered schemas.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's action: 'Get option chain for an expiry date.' It includes the return structure, specifying strikePrices with call/put fields. This is specific and distinguishes it from siblings like option_chain_expiry_date_list (which lists expiry dates) and option_quote (for a single option).

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explicitly says 'for an expiry date,' which implies the appropriate context. While it does not explicitly mention when not to use it or contrast with siblings, the naming and context make it clear that this tool is for obtaining the chain for a specific date, not for listing dates or quoting individual options.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already mark the tool as readOnly, openWorld, idempotent, and non-destructive, ensuring an agent knows it's safe. The description adds key behavioral insight: providing only one of the date parameters returns empty results. This goes beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two concise sentences: first states the main action, second clarifies parameter usage. No filler, front-loaded with purpose, efficient.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a tool with 3 parameters and no output schema, the description covers the purpose, required symbol, and optional date constraints with behavior. It could optionally mention the response nature, but it is adequately complete for its simplicity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema covers 100% of parameters, but the description reinforces the mutual dependency of start and end dates and explicitly states the empty result behavior for incomplete pairs. This adds practical value beyond the schema constraints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves 'detailed profit and loss analysis for a specific symbol,' using a specific verb and resource. It distinguishes from the sibling 'profit_analysis' by emphasizing 'detailed,' indicating a more granular report.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explains how to use the date parameters (both required together) and the consequence of misuse (empty results). However, it does not provide guidance on when to use this tool versus its sibling 'profit_analysis' or any other alternative.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate read-only, idempotent, non-destructive, and open-world hints. The description adds that execution is server-side and returns indicator/plot values as JSON, providing useful behavioral context beyond the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences plus a period list and input example. All information is front-loaded and no filler. Every sentence adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description explains the output is JSON of computed values. It covers main parameters and execution. However, it lacks details on error handling or script syntax, but is adequate for a script-running tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline is 3. The description adds value by explaining the period options (listing them with default) and the input parameter's format with an example, clarifying its relationship to script inputs.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool runs a quant indicator script against historical K-line data, specifying the verb 'run' and resource 'quant indicator script'. It is distinct from sibling tools as none appear to execute user-provided scripts.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description does not explicitly guide when to use this tool versus alternatives. It states the tool runs server-side and returns JSON, but does not mention prerequisites or compare to other indicator-related tools among siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate readOnlyHint=false (write operation) and openWorldHint=true. The description adds that it returns an upstream API response. It does not disclose other behavioral traits like idempotency, potential side effects, or error handling, so it adds minimal value beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is concise with two sentences, front-loading the core purpose. No redundant information. Every sentence adds value.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simple parameters (2 required, no nested objects, no enums) and no output schema, the description is sufficient. It doesn't elaborate on the upstream API response format, but that is acceptable for a straightforward tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has 100% coverage with descriptions for both parameters. The description adds an example of symbols format (e.g., AAPL.US, 700.HK), which provides practical guidance beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the action (add securities), the resource (community sharelist by id), and provides an example of symbols format. It effectively distinguishes from sibling tools like sharelist_remove or sharelist_create.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description instructs the user to provide symbols in a specific format, which is helpful. However, it lacks explicit guidance on when to use this tool versus alternatives (e.g., when not to use it, or prerequisites like sharelist existence).

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Description adds value beyond annotations by stating that the tool only works on own lists and returns the upstream API response. Annotations already indicate destructive and idempotent nature, so the description provides additional contextual constraints.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Description is extremely concise (27 words), front-loaded with the action, and contains no unnecessary words. Every sentence earns its place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple one-parameter delete operation with annotations covering destructiveness, the description adequately covers purpose, ownership constraint, and response. It could mention error handling or permissions, but overall is complete enough for an agent.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline is 3. The description does not enrich the parameter meaning beyond 'by id', and the schema already describes 'id' as 'Sharelist ID'. No additional semantic value is added.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description explicitly states the action (delete), the target (community sharelist by id), and includes constraints (own lists only) that distinguish it from sibling tools like sharelist_remove and sharelist_create.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Description provides a clear usage constraint: only own lists can be deleted, subscribed lists cannot. This tells the agent when and when not to use the tool, though it does not explicitly mention alternative tools for other sharelist operations.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare the tool as read-only and safe. The description adds value by detailing the return structure (list of fields) and special routing for certain crypto symbols, which goes beyond what annotations provide. It does not contradict annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is extremely concise, consisting of two sentences. The first sentence states the purpose and return fields, and the second adds a crucial special-case note. Every sentence adds value, and it is front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple read-only tool with one parameter and no output schema, the description is fairly complete. It explains what the tool returns and special behavior for specific symbols. Missing details like error handling for invalid symbols are not critical for the core functionality.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The input schema has one parameter 'symbols' with a clear description. The tool description adds no new semantic information about the parameter beyond stating it takes security symbols. Since schema coverage is 100%, the description meets the baseline.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Get static info for securities.' It lists specific fields returned per symbol and differentiates from siblings by specifying it provides static, non-time-varying data. The mention of special handling for .BKKT and .HAS/.OSL symbols further clarifies the scope.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description gives clear context for using the tool (to retrieve static security info) and includes a when-not case for .BKKT symbols with US accounts. However, it does not explicitly name alternative tools for .BKKT crypto or contrast with siblings like 'company' or 'quote', leaving some ambiguity.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare the tool as read-only, idempotent, and non-destructive. The description adds the return structure (array of executions with fields) and filtering behavior, complementing the annotations without contradiction.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single sentence followed by a list of return fields, conveying all essential information without extraneous text. It is efficient and front-loads the key purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The tool has no required parameters and a simple return type. The description adequately explains the output structure and filtering options. Minor gaps like behavior when no executions exist are not critical but could be added.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Both parameters are fully described in the input schema (100% coverage). The description merely restates the filtering capability ('Pass symbol or order_id to filter'), adding no new semantics beyond what the schema provides.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and the resource 'today's trade executions (fills)', specifying the scope (today). The return fields are listed, distinguishing it from sibling tools like history_executions and today_orders.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides clear context for use (today's executions) and informs filtering by symbol or order_id. However, it does not explicitly mention when not to use or point to alternative siblings like history_executions for other dates, though the name implies the scope.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations indicate non-readonly, non-destructive, open-world; description adds behavioral detail on topic_type and Markdown support, but no side effects or auth info.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences with clear front-loading; every word adds value, no fluff.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves capital inflow/outflow time series data, specifies the return structure (items with timestamp, inflow, outflow, net_flow), and notes it is same-day data. This verb+resource+scope is specific and distinguishes it from similar financial data tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description implies usage for obtaining capital flow data but does not explicitly state when to use versus alternatives like capital_distribution or other financial time series tools. No when-not-to-use or alternative tool guidance is provided.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already indicate non-read-only, non-destructive behavior. Description adds context about optional pre-population, which is useful beyond annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Both parameters are described in the schema with 100% coverage. Description mentions the optional securities parameter but adds no meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Clearly states 'Create a new watchlist group' with verb and resource, and distinguishes from sibling tools like delete_watchlist_group and update_watchlist_group.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Specifies optional use case with securities parameter, providing an example. No explicit when-not-to-use or alternatives, but the context is straightforward for a creation tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, destructiveHint. Description adds behavioral context about response shape variation for US accounts and percent value interpretation, which is not covered by annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences with zero waste. First sentence states core purpose, second adds critical caveat. No redundant information.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Tool has one parameter, good annotations, and an output schema exists (noted in description). The description covers the main behavior and a key exception, sufficient for a simple query tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Input schema has 100% coverage with a single symbol parameter. Description adds semantic nuance by explaining that the response shape depends on the symbol and account type, going beyond the schema's definition.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description states 'Get dividend history for the symbol' with a specific verb and resource. It distinguishes from siblings by noting a special response case for US accounts querying .US symbols.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines3/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    No explicit when-to-use or alternative tools mentioned. The description implies caution for US accounts with .US symbols but does not compare to sibling tools like dividend_detail.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds value by specifying the exact return fields (id, title, type, language, filing_date, url), but does not cover pagination or rate limits.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two sentences, no redundancy. Front-loaded with the core purpose and immediately followed by return format. Every word serves a purpose.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness3/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    The description covers purpose and return format, but lacks details on ordering, date range, or result limits. Given no output schema, more context (e.g., 'Returns up to 20 most recent filings') would improve completeness.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a single 'symbol' parameter. The description provides an example ('700.HK'), adding clarity beyond the schema. Baseline is 3, with the example earning an extra point.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves regulatory filings (8-K, 10-Q, 10-K) for a stock symbol and lists the returned fields. It distinguishes itself from sibling tools like 'news' or 'news_search' by specifying regulatory filings.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    While no explicit when/when-not guidance is given, the purpose is self-evident from the name and description. The tool is clearly for regulatory filings, distinguishing it from news or other data tools.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true and openWorldHint=true. The description goes beyond those by specifying what is returned—rule parameters, status, embedded grid_sub_orders, and grid_order_history—and by documenting cursor-based pagination behavior via history_id and limit. This adds useful behavioral context without contradicting the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two sentences and every clause contributes meaning. It front-loads the core purpose, then lists the included detail types and pagination behavior without redundancy or filler.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With an output schema present, the description does not need to explain return value shapes. It covers the tool's scope, included embedded entities, and pagination mechanism. This is sufficiently complete for a read-only detail-retrieval tool with only three inputs.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so the baseline is 3. The description's mention of 'history_id cursor + limit paging' reinforces the schema's existing parameter descriptions but does not add new semantic details beyond what the schema already provides. No extra parameter meaning is introduced.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb-resource combination: 'Full detail for one grid order,' immediately clarifying this is a single-order retrieval tool. It enumerates distinct contents (rule parameters, status, embedded child orders, lifecycle history), which clearly distinguishes it from siblings like grid_list or grid_trigger_history.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The phrase 'Full detail for one grid order' clearly signals when this tool is appropriate: when a single order's complete details are needed rather than a list or summary. It does not explicitly name alternatives or state when not to use it, but the contrast with list-oriented sibling tools is strongly implied.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The description adds a meaningful behavioral nuance beyond annotations: it applies to a 'running grid order' and clarifies that the operation is a pause, not a termination. The annotations already provide idempotentHint=true and destructiveHint=false, and there is no contradiction. It could mention side effects or status transitions in more detail, but the combination is sufficient for this simple operation.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is two short, front-loaded sentences. The first states the action and target; the second gives the resume path. Every word earns its place and no unnecessary detail is included.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a one-parameter mutation with full schema coverage, idempotent/destructive annotations, and a clear sibling relationship to grid_restart, the description is complete. It tells the agent what the tool does, what input it requires, and how to reverse the action. No output schema is present, but none is needed for such a simple suspend operation.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% for the single parameter order_id, which is documented as 'Grid order ID.' The description merely repeats 'by order_id' without adding format, source, or lifecycle details, so it adds little beyond the schema. A baseline 3 is appropriate because the schema already fully documents the parameter.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description uses a specific verb ('Suspend (pause)') and names the resource ('running grid order by order_id'). It clearly distinguishes this from sibling tools like grid_cancel, grid_restart, and grid_replace by stating the action is a pause, not a cancellation or restart.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description clearly indicates when to use the tool: to suspend a running grid order. It also explicitly mentions the counterpart, 'Resume with grid_restart,' which helps an agent choose between alternatives. It stops short of listing exclusion cases or conditions like 'do not use if order is already paused,' so it is strong but not exhaustive.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    The read-only and open-world hints already signal this is a safe lookup. The description adds helpful behavioral context by detailing what the response includes, such as price-step tables and authorization/channel info, while clarifying that the lookup is symbol-based rather than order-based. No contradiction with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is one dense, front-loaded sentence that communicates purpose, inputs, and output content efficiently. However, it appears truncated mid-sentence ('supported s...'), which slightly reduces polish and completeness.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness4/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the single parameter, full schema coverage, and read-only annotations, the description is mostly sufficient. It conveys the expected output and usage context well; only the truncated ending prevents a perfect score.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema already describes the single required parameter with a concrete example ('700.HK'), so baseline coverage is high. The description's added clarification that the tool takes 'a symbol, not an order_id' adds real semantic value by preventing confusion with order-based endpoints.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description explicitly states the tool provides 'pre-trade grid setup info for a security' and enumerates distinct outputs: security name, last price, board lot sizes, price-step table, and channel/authorization info. The phrase 'takes a symbol, not an order_id' also helps distinguish this tool from order-based grid tools like grid_detail.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The phrase 'pre-trade grid setup info' establishes a clear usage context: use this when setting up a grid trade for a security before submitting an order. The explicit note that it takes a symbol rather than an order_id provides useful direction away from order-specific tools, though it does not name sibling alternatives explicitly.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false, so safety is covered. The description adds useful behavioral context by specifying that exactly one article is retrieved, that the lookup is by ID, and that IDs originate from `news`/`news_search`—value beyond the annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is a single, front-loaded sentence with no filler or redundancy. Every word contributes to identifying the action, resource, and context.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the low complexity (one required parameter), strong annotations, full schema coverage, and presence of an output schema, the description is sufficient. It tells the agent what the tool does, where the input comes from, and how it relates to sibling tools.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100% and the single `id` parameter is already well documented with type, example, and source guidance ('Get IDs from news or news_search'). The description's mention of `(from news/news_search)` adds no new semantic meaning beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description uses a specific verb ('Get') and resource ('one news article's full detail') with a clear access path ('by id'). It naturally distinguishes from siblings like `news` and `news_search` by indicating this is a single-article detail lookup rather than a list/search operation.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description clearly places this tool after `news` or `news_search`, implying it should be used when you already have an article ID and need full details. It provides clear context but does not explicitly state when not to use it or mention alternative detail tools among the siblings.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, openWorldHint=true. The description adds the return format (RFC3339 string) and usage hint, which is useful but not extensive. No contradictions with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description consists of two sentences with no wasted words. It is front-loaded with the key action and format, then provides usage context. Perfectly concise.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given the simplicity (no parameters, no output schema, clear annotations), the description is complete. It explains the return value format and the primary use case, leaving no gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The tool has zero parameters, so schema coverage is 100%. Baseline is 4, and the description does not need to add parameter information. It correctly avoids mentioning parameters.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the verb 'Get' and resource 'current UTC time as an RFC3339 string'. The tool name 'now' and title 'Current Time' align perfectly. It distinguishes from sibling tools which are mostly data retrieval or trading tools, none of which just return the current time.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explicitly says 'Use to determine current date/time before making date-based queries', providing clear guidance on when to use this tool. It does not mention when not to use, but given the simplicity, that is acceptable.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior3/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint=true, idempotentHint=true, etc. Description adds context about parameter pairing and empty results, which is helpful but not extensive.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a simple tool with one parameter and an output schema, the description is complete. It explains what the tool does and how to execute the strategy, and the output schema covers return values.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema description coverage is 100%, and the schema already fully describes the single parameter 'id'. The description does not add extra parameter info, so baseline 3 is correct.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool's purpose: 'Inspect a screener strategy's filter conditions before running it.' It uses specific verbs and resources, and distinguishes it from the sibling tool 'screener_search' which executes the strategy.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description explicitly tells when to use this tool (inspect before running) and provides an alternative: 'Use screener_search strategy_id to execute the strategy.' This clearly differentiates usage scenarios.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare the operation as read-only, idempotent, and non-destructive. The description adds useful behavioral context beyond annotations: the result is limited to Top 20 holders, spans reporting periods, and outputs an object_id usable with shareholder_detail. No contradiction with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Two short sentences deliver the core purpose and the key drill-down workflow. No filler or redundancy exists, and the most important information is front-loaded.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    For a single-parameter, output-schema-backed read-only tool, the description is sufficient: it defines scope, data categories, reporting-period behavior, and the related drill-down path. The presence of an output schema and strong annotations further reduces the need for extra explanatory text.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    The schema fully documents the single 'symbol' parameter with an example, so the description does not need to repeat that. The mention of 'object_id' is not a schema parameter but is useful context about the returned data, and it adds a small amount of semantic value beyond the schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description starts with a specific action and resource: 'Get Top 20 major shareholders', with clear categories (institutions, individuals, insiders) and reporting-period coverage. It distinguishes itself from the sibling 'shareholder_detail' by framing the top-level view and pointing to the drill-down tool.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description clearly implies when to use this tool: to retrieve the top-20 shareholder list across reporting periods. It also provides composability guidance by referencing 'object_id with shareholder_detail' for deeper holder history, although it does not exhaustively compare against every sibling tool.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already provide readOnlyHint, idempotentHint, and others. The description adds that the tool returns a pre-signed URL, which is a key behavioral detail. No contradictions with annotations; the description enhances transparency about the output format.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters3/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100% with a single parameter 'file_key' that has a detailed description and example. The tool description does not add additional meaning beyond what the schema provides, so the baseline score of 3 is appropriate.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, so baseline 3. Description adds valuable context by providing examples for key, explaining market inference logic, and noting default size. This goes beyond the schema descriptions.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    Description clearly states it gets a ranked stock list by leaderboard tab key. It distinguishes from sibling 'rank_categories' (which provides category keys) and other list tools, and explains the key parameter's source.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly explains how to obtain the key from rank_categories second_tags[].key and gives examples. Also clarifies market inference and default size. Could be improved by explicitly stating when to use this versus rank_categories.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior4/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Description aligns with annotations (not read-only, destructive). Adds context on specific modifications (add/remove/replace), which implies potential destructive behavior. No contradictions with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given only one parameter, no output schema, and clear annotations, the description is complete: it explains the output format and how to use the result with a sibling tool.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters4/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema has 100% coverage with a clear description for the only parameter 'symbol'. The description reinforces with an example ('AAPL.US'), adding value beyond schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states the tool retrieves option chain expiry dates for a symbol, indicates output format as 'yyyy-mm-dd' strings, and distinguishes from sibling tool 'option_chain_info_by_date' by noting they are used together.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines5/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Explicitly tells when to use this tool (to get expiry dates) and directs to 'option_chain_info_by_date' for strikes and Greeks, providing a clear workflow and alternative.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false. The description adds behavioral details beyond annotations: market inference logic, data sources (FINRA bi-weekly, HKEX daily), and per-market differences (US-only avg_daily_vol, days_to_cover; HK-only balance). There is no contradiction.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness4/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    The description is well-structured with front-loaded purpose and clear field breakdowns. It is somewhat verbose but every sentence adds value (sources, per-market details, count range). Could be slightly tighter but highly effective.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    Given no output schema, the description thoroughly explains the output fields for both markets, including sources and count constraints. It covers all necessary context for an agent to correctly invoke and interpret the tool, leaving no significant gaps.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters5/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, and the description adds significant meaning: 'count' default 20, 'symbol' market inference from suffix. It also explains the returned data structure fields (timestamp, short_shares, rate, close) with per-market additions, compensating for the lack of an output schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states 'Get short interest history (open short positions) for HK or US stocks' with explicit differentiation from siblings like 'short_margin' and 'short_trades'. It specifies the resource (short interest history) and the action (get), distinguishing it from other short-related tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    The description provides usage context such as 'Market inferred from symbol suffix' and 'count: 1–100 (default 20)'. While it does not explicitly state when to use vs. alternatives, the sibling context and description imply this is for open short positions history, which is sufficiently clear for agents.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

  • Behavior5/5

    Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

    Adds important behavioral details beyond annotations: excludes today, lists exact return fields, and describes pagination via a separate endpoint. No contradictions with annotations.

    Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

    Conciseness5/5

    Is the description appropriately sized, front-loaded, and free of redundancy?

    Three front-loaded sentences with no waste. Purpose, return shape, and pagination details each earn their place.

    Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

    Completeness5/5

    Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

    With 5 params and no output schema, the description fully covers return fields, required parameters, and US-specific pagination. No gaps given the tool's complexity.

    Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

    Parameters5/5

    Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

    Schema coverage is 100%, but description adds significant meaning: explains RFC3339 format, clarifies us_page/us_limit pagination behavior (separate endpoint, default size), and states US-only restriction not in schema.

    Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

    Purpose5/5

    Does the description clearly state what the tool does and how it differs from similar tools?

    The description clearly states it gets historical orders between dates, excludes today, and lists return fields. It implicitly distinguishes from 'today_orders' and other order-related tools.

    Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

    Usage Guidelines4/5

    Does the description explain when to use this tool, when not to, or what alternatives exist?

    Specifies US accounts only and explains pagination behavior. Provides clear context for when to use (historical period) but does not explicitly compare to sibling tools like 'today_orders'.

    Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
