Server Quality Checklist

Profile completionA complete profile improves this server's visibility in search results.

Latest release: v0.1.0
Disambiguation4/5
Most tools have clear, distinct purposes, e.g., get_ai_performance vs get_ai_performance_reports. However, some overlap exists: get_financials and get_bctc_summary both provide financial ratios, and get_ta_narrative includes technical signals overlapping with get_technical_signals. Playbook tools are numerous but differentiated by domain.
Naming Consistency4/5
The vast majority follow a consistent 'get_<noun>' pattern (e.g., get_ai_performance, get_market_snapshot). Two tools, screen_stocks and search_stocks, break the pattern by using verbs without 'get', but they are clearly distinct actions. No mixing of naming conventions (camelCase, snake_case) is observed.
Tool Count3/5
At 35 tools, the server is on the high end of the acceptable range. The domain (Vietnamese stock market intelligence) is broad, justifying many tools, but it feels slightly overloaded with 13 playbook tools that could potentially be consolidated. Still, it remains navigable.
Completeness4/5
The tool set covers a wide range of investment data: performance, financial statements, technical signals, sentiment, macro, insider trading, foreign flow, sector rotation, screening, and playbooks for various scenarios. Minor gaps may exist (e.g., explicit dividend data, portfolio management actions), but the surface is largely complete for a read-only data server.
Average 3.6/5 across 35 of 35 tools scored. Lowest: 2.9/5.

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

Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, destructive, idempotent hints. Description adds that it searches Vietnamese stocks and filters by sector, but no additional behavioral traits (e.g., case sensitivity, pagination). With good annotation coverage, 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.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two sentences; the first clearly states purpose, but the second is a redundant Vietnamese translation that adds no value for an English-speaking agent. Could be more concise by removing the duplicate.
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?
Description does not mention the 'limit' parameter, output format, or how it differs from similar tools like 'screen_stocks'. With no output schema, the agent lacks crucial information about 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?
All three parameters have descriptions in the input schema (100% coverage). The description mentions search by ticker/name and sector filter, reinforcing schema but adding no new details beyond the examples already present in 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?
Description clearly states it searches Vietnamese stocks by ticker or company name with optional sector filter. However, it does not differentiate from the sibling tool 'screen_stocks', which likely has similar 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?
No guidance on when to use this tool vs alternatives like 'screen_stocks' or other get_* tools. The description lacks context on prerequisites or limitations.
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 behavior. The description adds no additional behavioral context (e.g., pagination, result format). It meets the minimum but does not enhance 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is brief (two sentences) and front-loaded with the primary purpose. The inclusion of a Vietnamese translation is somewhat redundant but does not significantly harm conciseness.
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 lacks details about return values (no output schema) and does not elaborate on the scope or depth of the checklists. Given the number of sibling tools, more context is needed for effective 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 description coverage is 100%, and the description does not provide any extra meaning for parameters beyond what is in the schema. Baseline score 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 tool provides pre-investment due diligence checklists for Vietnamese stocks, which is a specific verb+resource. While it distinguishes from siblings by being checklist-specific, it does not explicitly contrast with alternatives.
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 the many sibling tools (e.g., get_financials, get_market_snapshot). The description does not mention prerequisites or appropriate contexts.
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 readOnly, non-destructive, and idempotent behavior, so the description does not need to cover these. It adds the context of 'personal wealth building' but no additional behavioral details (e.g., data freshness, pagination). With good annotation coverage, a baseline 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 concise with two sentences (English and Vietnamese) and no fluff. It's front-loaded with the key purpose. However, it could be slightly restructured to improve clarity for an agent, but overall it's efficient.
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 the large number of siblings (30+), the description lacks differentiation. It doesn't explain what a 'playbook' is or what the return format looks like. With no output schema, more behavioral context is needed. Complexity is low, but completeness is inadequate for effective tool 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 description coverage is 100%, so the input schema fully documents both parameters. The description hints at filtering by category via 'allocation by age/risk' but doesn't explicitly explain the 'category' parameter. Thus, it adds no significant value beyond the schema, warranting a baseline 3.
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 personal wealth building playbooks, covering savings and allocation by age/risk. It distinguishes from siblings like 'get_fund_playbooks' or 'get_commodity_playbooks' by focusing on general personal wealth. However, it could be more specific about what constitutes a wealth playbook.
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 vs. alternatives. The description implies it's for personal wealth, but doesn't mention when not to use it or provide comparisons to siblings like 'get_bank_rate_playbooks' or 'get_macro_playbooks'. Agent must infer usage from the name alone.
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 details beyond the general topic; it does not disclose rate limits, authentication needs, or the fact that it returns playbooks. With annotations present, a score of 3 is appropriate as it neither adds nor contradicts.
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 with two lines, front-loading English then Vietnamese. No unnecessary words, but the Vietnamese is redundant. It could be slightly improved by stating it returns playbooks, but overall it is efficiently short.
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 no output schema, the description does not explain what a playbook is or the return format. However, the tool is simple (two optional params, low complexity), so the description is minimally adequate. It would benefit from mentioning the structure of returned playbooks.
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 'category' and 'limit' having descriptive comments. The description does not elaborate on these parameters or add meaning beyond the schema. Baseline is 3 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 handles money flow analysis (foreign, institutional, retail) and includes a Vietnamese translation for context. It distinguishes from siblings like 'get_foreign_flow' by focusing on playbooks, though it could be more explicit that it returns playbooks rather than performing analysis.
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 'get_foreign_flow' or other playbook tools. There is no mention of prerequisites, exclusions, or scenarios 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 show readOnlyHint and idempotentHint, so the description adds modest value by mentioning 'by market cycle' and 'outperforming VN sectors'. However, it does not detail return format, pagination, or other behavioral traits 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is very short and front-loaded, with only two sentences. The Vietnamese translation is slightly redundant but does not significantly harm conciseness.
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 (2 parameters, read-only), the description is adequate but does not explain what a playbook is or what the output contains. For a user unfamiliar with 'playbooks', more context would be needed.
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 already documents both parameters. The description does not add any additional meaning or context to the parameters beyond what is in the input 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 tool identifies outperforming VN sectors based on market cycle, using a specific verb-resource combination. It distinguishes from sibling playbook tools by focusing on sector rotation and market cycles, but the Vietnamese translation adds redundancy.
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 other playbook tools or under what conditions. The description lacks any when-to-use or when-not-to-use instructions.
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, destructiveHint, and idempotentHint, so the description does not need to cover safety. It adds the list of signal types (RSI, MACD, etc.), which is useful behavioral context beyond annotations. However, it does not disclose whether signals are for the latest data or historical, or if any rate limits or data freshness considerations apply. With annotations present, this is acceptable but not exceptional.
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 gets to the point immediately. The first sentence lists the key signals. The second sentence repeats in Vietnamese, which is redundant for English-speaking agents but not harmful. The structure is front-loaded with the most important 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?
Given the lack of an output schema, the description should ideally explain what the returned data looks like. It lists the signals but does not describe format (e.g., object with fields) or if it returns a single object or array. The parameter 'days' suggests a time range, but no mention of whether it returns one signal per day or aggregated. Contextually, it is adequate for a simple tool but leaves gaps.
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 describes both parameters (symbol and days) with 100% coverage. The description does not add any additional semantics or constraints beyond what the schema provides (e.g., no hint about ticker format or default days). Since schema coverage is high, the description does not need to compensate, but it also does not enhance 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?
The description clearly states it returns technical analysis signals including RSI, MACD, Bollinger Bands, buy/sell votes, and confidence score. It specifies the resource (technical signals) and verb (get), making its purpose clear. However, it does not differentiate from sibling tools such as get_price_history or get_financials, which are conceptually distinct but not contrasted 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?
The description provides no guidance on when to use this tool versus other technical or fundamental analysis tools. It does not mention any prerequisites, recommended context (e.g., 'use when you need overbought/oversold indicators'), or mention that it is for historical signals rather than real-time. This lack of usage direction forces the agent to rely solely on tool naming.
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 and idempotentHint=true, so the safe, idempotent nature is covered. The description adds no behavioral context beyond that, such as whether results are cached, pagination behavior, or any special authentication requirements.
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 short, consisting of two phrases. It is front-loaded with the English content but includes a Vietnamese translation that adds no functional value for an AI agent. It could be more structured or richer within the same length.
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?
No output schema exists, so the description should inform what the tool returns. It mentions topics (war impact, oil price, defense stocks) but does not describe the structure of the response (e.g., list of playbooks with titles, summaries, dates). It lacks completeness for a 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% and parameter descriptions in the schema are adequate ('Filter by playbook category/tag', 'Max results to return (default: 10)'). The tool description adds no additional parameter semantics, but because schema coverage is high, baseline score is 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 provides geopolitical risk playbooks specifically covering war impact, oil price, and defense stocks. This is a specific verb-resource combination that distinguishes it from sibling playbook tools that cover other domains like commodities or macro.
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 geopolitical risk playbooks are needed, but does not provide explicit guidance on when to use this tool versus alternatives like get_commodity_playbooks or get_macro_playbooks. No exclusions 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?
Annotations already declare readOnlyHint=true and destructiveHint=false. The description adds the context of 'insider trading transactions' but does not disclose additional behavioral traits like pagination or data freshness 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?
Two short sentences, front-loaded in English, zero waste. Efficient and clear.
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?
For a simple data retrieval tool with 2 parameters, rich annotations, and no output schema, the description is adequate but could benefit from indicating typical return fields (e.g., transaction date, volume) to 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% with descriptions for both 'symbol' and 'days'. The description does not add extra meaning to the parameters beyond what the schema already provides, resulting in baseline score.
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 returns insider trading transactions (buy/sell) by executives and major shareholders. It is distinct from sibling tools like get_whale_activity, but does not explicitly differentiate itself.
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 get_whale_activity or get_news_sentiment. The description lacks usage 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 provide readOnlyHint=true, destructiveHint=false, idempotentHint=true. The description adds only the scope (Vietnamese stocks) but no additional behavioral traits such as rate limits, data update frequency, or behavior when 'days' exceeds 365. With annotations carrying the safety profile, the description contributes little.
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: one sentence in English and one in Vietnamese, both front-loaded with the essential purpose. 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?
The description implies the return format (OHLCV) which partially compensates for the missing output schema. However, it omits details like data source, maximum date range (though schema specifies max 365 days), or handling of missing data. Still, it provides adequate context for a simple history tool.
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% with both 'symbol' and 'days' described clearly in the schema. The description does not add any parameter-specific meaning beyond what the schema already provides (e.g., format of symbol, what 'days' counts). Baseline is 3 due to high coverage, but lack of added value drops the score.
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 'OHLCV price history for individual Vietnamese stocks,' specifying the verb (get implied), resource (price history), and scope (individual Vietnamese stocks). This differentiates it from siblings like 'get_index_history' (index-level) and 'get_realtime_quote' (realtime vs historical).
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 scenarios where other tools like 'get_index_history' or 'get_realtime_quote' might be more appropriate, nor provides any when-not-to-use advice.
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 and idempotent. The description adds content details (monthly, per-stock breakdown) but does not disclose other behavioral traits like auth requirements or output 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?
The description is extremely concise: two short sentences (English and Vietnamese) that front-load the core action without unnecessary detail.
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, safety annotations), the description provides sufficient context for basic usage. However, it could clarify the relationship with 'get_ai_performance'.
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 tool description implies the 'month' parameter but adds no additional semantic value beyond the schema's explanation.
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 'detailed monthly AI performance reports with per-stock breakdown', specifying verb and resource. However, it does not differentiate from the sibling tool 'get_ai_performance', which could cause ambiguity.
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 vs alternatives like 'get_ai_performance' or other report tools. The description lacks context for usage decisions.
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, indicating a safe, idempotent read operation. The description adds no behavioral context beyond the topic (e.g., no mention of data freshness, pagination, or authorization). With annotations carrying the burden, 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 short (two sentences) and front-loaded with the English purpose. The Vietnamese translation is redundant but not detrimental. It is concise and to the point, though a single clear sentence would be more efficient.
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 parameter set (2 optional, no required) and lack of output schema, the description is adequate but lacks detail about what the playbooks contain, filtering options, or result format. Annotations cover safety. Could be improved by mentioning typical category values or that results are a list of strings/objects.
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 documented (category filter, limit). The description does not add meaning beyond the schema—it only provides domain context. Per guidelines, baseline is 3 when schema coverage is high.
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 retrieves playbooks related to Vietnam business dynasties (family-owned conglomerates). The description uses specific terms ('gia tộc kinh doanh') and differentiates from sibling tools like get_bank_rate_playbooks or get_bds_playbooks, which focus on other categories.
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 the many sibling playbook tools (e.g., get_bank_rate_playbooks, get_macro_playbooks). There is no mention of prerequisites, context, or exclusions, leaving the agent to infer usage solely from the name.
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 list of opinion components, but no further behavioral details (e.g., data freshness, error handling).
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?
Two short sentences, but one is a duplicate translation. Front-loaded with useful information, yet could be more concise by removing the Vietnamese line.
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?
For a simple one-parameter tool with good annotations, the description covers the purpose but lacks detail on the output format or any special behavior. Could be more complete about what the returned opinion looks like.
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 parameter description. Description does not add any additional semantics beyond indicating the ticker symbol, 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?
Description clearly states the tool retrieves an AI-synthesized opinion on a stock, listing specific components (moat, ESG, insider signal, analyst consensus). It distinguishes itself from sibling tools like get_ai_performance or get_financials, which cover different aspects.
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, or any prerequisites or exclusions. The description only states what it does, not when to invoke 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?
Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true. The description adds no additional behavioral context (e.g., return characteristics, rate limits). It is consistent but not enriched.
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?
Description is short—two sentences (English then Vietnamese). It is front-loaded with the key concept. The Vietnamese may be redundant for English-only agents but does not add significant clutter.
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 simplicity (2 optional params, no output schema), the description minimally explains the tool's purpose. It does not describe the return format or what a 'playbook' entails, which could be helpful for new agents.
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?
Input schema has 100% coverage for both parameters (category, limit) with descriptions. The tool description does not add any additional meaning or examples beyond what the schema already 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?
Name and description clearly indicate the tool retrieves playbooks related to trading psychology, behavioral finance, and fear/greed management. It is well differentiated from sibling playbook tools (e.g., get_macro_playbooks) by the 'psychology' category.
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. With many sibling playbook tools, explicit usage context or exclusion conditions are missing.
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 and destructiveHint=false, indicating safe, read-only behavior. The description adds no extra behavioral details (e.g., rate limits, auth needs, scope of results). With annotations covering safety, description is adequate but not enriched.
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: two short sentences, no fluff. Front-loaded with the core purpose. Every word earns its place. Ideal for quick agent parsing.
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 screening tool with 2 parameters and full schema coverage, the description is fairly complete. It mentions the number of strategies and examples. Missing output format but no output schema exists; agent can infer typical stock screening results. Adequate but could hint at output structure.
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?
Input schema has 100% description coverage for both parameters ('strategy' and 'min_score'). The description does not add new meaning beyond the schema; it merely mentions '13 strategies' but without listing them. Baseline 3 is appropriate since schema already handles parameter semantics.
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 tool screens stocks using 13 strategies ('Buffett, Graham, Piotroski...'). The verb 'screening' and resource 'stocks' are explicit. However, it does not differentiate from sibling tools like 'search_stocks' or 'get_stock_info', which could cause confusion.
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. The description only states what it does, not when it is appropriate or when to avoid it. Missing explicit when-to-use/when-not-to-use 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 and idempotentHint, so the tool's safe, non-destructive behavior is known. The description adds no further behavioral traits beyond the 'Vietnamese stock' context. It does not mention rate limits, authentication needs, or what happens if the symbol is invalid.
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: one English sentence followed by a Vietnamese translation. Every word is meaningful and front-loaded with the key ratios. No redundant or extraneous content.
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 parameter, no output schema), the description covers the main purpose and lists example outputs. However, it does not specify the number of years returned, whether data is trailing or fiscal year, or any time range flexibility. With no output schema, additional detail on return structure would improve 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 coverage is 100% for the single parameter 'symbol', which is already described as 'Stock ticker'. The description adds the context that it applies to Vietnamese stocks, providing marginal semantic value. However, it does not elaborate on format or special characters beyond what the schema states.
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 provides annual financial ratios (ROE, ROA, margins, P/E, P/B) specifically for Vietnamese stocks. It uses a specific verb-resource combination and lists example ratios, distinguishing it from sibling tools like get_stock_info or get_price_history.
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 the tool is used to obtain annual financial ratios for a Vietnamese stock, but it does not explicitly state when to use it versus alternatives such as get_stock_info or get_technical_signals. There is no guidance on when not to use it or any prerequisites.
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. The description adds the specific macroeconomic domains (GDP, CPI, FDI) but does not disclose additional behavioral traits such as pagination 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 very short and front-loaded with the core purpose. The inclusion of a Vietnamese phrase adds minimal value and slightly reduces conciseness for an English-speaking 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 read-only tool with two simple parameters and no output schema, the description is adequate. It states what the tool returns, though it could be more specific about the format or content of the playbooks.
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 (category, limit) having full descriptions. The description implies category may filter by macro topics but does not add explicit meaning beyond the schema.

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 compared to other playbook tools. The description does not mention exclusions or alternatives, leaving the agent to infer based on the topic alone.
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 Vietnam and bank rate context but does not disclose additional behavioral traits such as data freshness, prerequisites, or limitations. With annotations present, the description adds marginal value.
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, with two short sentences front-loaded with relevant information. It avoids fluff, but could include more useful details without significantly increasing length.
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 and the presence of annotations, the description is minimally adequate. However, it lacks details on expected output format, parameter usage hints, and when to select this tool over similar siblings. It leaves gaps for an agent to fill.
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 documented. The description does not add any meaning beyond the schema, such as acceptable values for 'category' or behavior defaults. Baseline is 3, and no extra information is 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 tool retrieves investment playbooks based on bank interest rate scenarios in Vietnam. It uses a specific verb 'get' and resource 'playbooks' with a distinct context, differentiating it from sibling tools like get_bds_playbooks or get_commodity_playbooks.
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 bank interest rate scenarios but provides no explicit guidance on when to use this tool versus alternatives, nor any when-not-to-use conditions. The agent must infer from context, lacking direct recommendations.
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, destructiveHint=false, idempotentHint=true. Description adds behavioral context by specifying computed metrics (ROE, ROA, etc.) and that it supports multiple analysis strategies. No contradiction with annotations. Description enriches transparency 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Description is concise: two English sentences and one Vietnamese translation. Front-loaded with main function. Each sentence adds value. Could be slightly more compact by combining, but 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?
Covers main outputs and strategies, but lacks explanation of how strategies are invoked (parameter only has symbol); no mention of return format or that it may return all strategies. With no output schema, more detail on results would be helpful. 'BCTC' may be ambiguous without full name in English.
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 parameter 'symbol' described as 'Stock ticker, e.g. FPT, VNM, VCB'. Description adds context that it is for Vietnamese stocks, but does not provide additional parameter details beyond schema. Baseline 3 justified.
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 retrieves financial statement analysis for a Vietnamese stock, listing specific metrics (ROE, ROA, debt ratios, Altman Z-score) and strategies (Buffett, Graham, Lynch, O'Neil, Piotroski). Distinct from siblings like 'get_financials' which likely returns raw data, and 'get_stock_info' which is general info. Verb 'Get' and resource 'BCTC analysis' 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 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 siblings such as 'get_financials', 'get_technical_signals', or 'screen_stocks'. Does not state prerequisites, context, or exclusions. An agent cannot determine from description alone when this is the appropriate choice.
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, destructiveHint, and idempotentHint. The description adds no behavioral context beyond the topic (pricing, location, financing), which is about content, not 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?
Two English sentences and one Vietnamese sentence, front-loading purpose. Every sentence is informative without 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?
Given no output schema, the description adequately explains return values (top 10 lists, totals, foreign %). However, it lacks temporal context (e.g., current day vs. historical) and potential edge cases.
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, so baseline is 4. Description adds no parameter info, but none 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 foreign investor net buy/sell flow for HOSE, listing specific components (top 10 net-buy/sell stocks, total value, foreign %). This verb+resource combination is well-defined and distinct 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 on when to use this tool versus alternatives like get_market_snapshot or get_sector_rotation. 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?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. Description adds that the tool covers 'impact' of events, but provides no further behavioral details (e.g., pagination, rate limits). Adequate given 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
Two short sentences (one English, one Vietnamese). Minimal waste, though the Vietnamese may be redundant for English users. Information is front-loaded.
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 low complexity, no output schema, and sibling tools that likely share a structure, the description provides domain context but omits details on return format or playbook contents. Adequate but 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 description coverage is 100%, so the schema already describes both 'category' and 'limit' parameters. Description does not add any additional meaning beyond the schema, 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?
Description clearly identifies the tool as retrieving political playbooks with a focus on policy events and government personnel changes. This distinguishes it from sibling tools like get_bank_rate_playbooks or get_commodity_playbooks.
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?
Context is clear: use for political alpha. No explicit exclusions or alternatives, but the domain specificity helps an agent decide when to select this tool over others.
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 idempotentHint=true, so the safety profile is clear. The description adds no additional behavioral traits (e.g., rate limits, response size, authentication needs) beyond listing returned data.
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 in English and one in Vietnamese, concisely convey the tool's purpose with no extraneous information. The key features are 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?
With no output schema, the description adequately lists the categories of returned data (profile, price, ratios, moat). However, it does not specify exact fields or structure, which could be improved but is sufficient for agent inference.
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% description coverage for the single parameter 'symbol', and the description does not add further context. Baseline 3 is appropriate as the schema already documents the parameter effectively.
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 company profile, latest price, key financial ratios, and moat score, with the phrase 'all in 1 call' indicating a composite view. This differentiates it from specialized sibling tools like get_financials or get_realtime_quote.
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 a comprehensive stock overview but provides no explicit guidance on when to use this versus alternatives (e.g., get_financials for detailed financials). No 'when not to use' or alternative tool names 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?
Annotations already declare readOnlyHint, destructiveHint, and idempotentHint. The description adds useful context about the data coverage (countries and indicators) without contradicting annotations. It does not detail behavioral traits like filtering defaults or data freshness, but the annotations cover safety and idempotency.
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 short and front-loaded with the key purpose. However, it includes a redundant Vietnamese translation which adds length without value for an English-speaking agent. This slight inefficiency prevents a perfect 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?
Given the simplicity (one optional param, no output schema), the description adequately covers the what (indicators) and where (countries). It lacks details on output format or whether values are current/historical, but for a snapshot tool, this is 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?
With 100% schema coverage, the input schema already describes the single parameter 'category' as 'Filter: vietnam, us, china, commodities.' The description does not add additional semantics beyond listing the indicators. 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 'Vietnam + US + China macro indicators: GDP, CPI, interest rates, FX, gold, oil.' It specifies the resource and scope, distinguishing it from siblings like get_macro_playbooks or get_commodity_playbooks which likely provide analysis rather than raw snapshots.
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 macro data, but provides no explicit guidance on when to use this tool versus alternatives (e.g., get_macro_playbooks, get_commodity_playbooks). No exclusions 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?
Annotations already declare readOnlyHint, destructiveHint, idempotentHint, and openWorldHint. The description adds no additional behavioral traits beyond stating the events covered. 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 extremely concise, with two lines covering both English and Vietnamese. Every word adds value, no filler.
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 two optional parameters and no output schema, the description adequately conveys the purpose and data. It could mention that dividends are a supported event type not in the schema's example, but overall sufficient.
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 covers both parameters with descriptions (100% coverage). The description adds value by listing specific event types like dividends, which are not fully enumerated in the schema's type parameter description.
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 handles corporate events such as personnel changes, shareholder meetings, and dividends. It clearly distinguishes itself from siblings like get_insider_activity or get_market_snapshot by focusing on these specific event types.
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 examples of event types but does not specify when to use this tool versus alternatives. No exclusion criteria or context for filtering by symbol or type beyond what is in the schema.
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 behavior. Description adds real-time with 15min delay, foreign flow, and intraday OHLC option, enriching behavioral context 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?
Two concise English sentences plus a Vietnamese translation, front-loaded with key information, 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 covers main outputs (price, foreign flow, intraday bars) adequately for a simple quote 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% with descriptions matching the description text; no additional parameter meaning is provided beyond what the schema already states.
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 the latest stock price from SSI FastConnect, distinguishing it from historical or market-wide tools among siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?
Usage context is implied (real-time vs historical) but no explicit when/when-not or alternative tool names are 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=true, destructiveHint=false, idempotentHint=true. The description adds that it returns a heatmap with avg return, volume, and stock count, but does not disclose update frequency, time range, or whether it's real-time or historical. 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?
Three very short sentences: first defines the output, second states the purpose, third is a Vietnamese translation. No wasted words; front-loaded with key 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 no output schema and no parameters, the description covers the return structure (heatmap with three metrics) and purpose. However, it could be more complete by specifying time range (e.g., daily, current) or frequency. Still adequate for a read-only 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 no parameters (empty), so description coverage is irrelevant. The description adds meaning beyond the schema by describing the output structure (three metrics, identifies hot/cold sectors). The information provided compensates for missing 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 the tool provides a 'sector rotation heatmap' with specific metrics (average daily return, total volume, stock count) and identifies hottest/coldest sectors. It distinguishes from siblings like get_sector_rotation_playbooks and get_market_snapshot.
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 identifying hot/cold sectors but gives no explicit guidance on when to use this vs. alternatives (e.g., get_sector_rotation_playbooks, get_market_snapshot). No exclusions or cautions are 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 provide safety profile (readOnly, idempotent, non-destructive). The description adds value by clarifying it's a daily snapshot that combines all data collectors, which informs the agent about data freshness and scope. 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
3 sentences, front-loaded with purpose. The Vietnamese translation is slightly redundant but does not harm conciseness. Every sentence contributes 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 no output schema, the description sufficiently explains the tool's output by listing the 13 data collectors. It mentions 'daily snapshot' for timing context. Could be improved by hinting at return format, but overall complete for a zero-parameter tool with good annotations.
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 0 parameters with 100% coverage, so baseline is 4. The description adds context about what data is included (the 13 collectors), which helps the agent understand the output without needing parameter details.
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 'Complete daily market intelligence snapshot' and lists all 13 data collectors, distinguishing it from sibling tools that focus on individual aspects like get_macro_snapshot or get_sector_rotation.
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 a broad overview ('single call for comprehensive overview') but does not provide explicit guidance on when to use this vs. individual collectors or alternative snapshots. 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?
Annotations already declare readOnlyHint, destructiveHint, idempotentHint, and openWorldHint. The description adds that results are sorted by volume ratio, which is a useful behavioral detail. No contradictions, and the description adds 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 with two sentences (plus a Vietnamese translation) that front-load the key information. Every word serves a purpose, and there is no 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?
While there is no output schema, the description adequately explains that the tool returns stocks with abnormal volume sorted by volume ratio. It could mention additional output fields, but for a zero-parameter detector, it is sufficiently complete.
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?
The input schema has no parameters, so schema description coverage is 100%. The description correctly communicates that no input is required, and it clarifies the output structure. No additional parameter information 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 identifies the tool as a whale/institutional activity detector, specifying that it lists stocks with abnormal trading volume (>2x the 20-day average) sorted by volume ratio. This meaningfully distinguishes it from siblings like get_market_snapshot or get_foreign_flow.
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 the tool should be used to detect whale activity, but provides no explicit guidance on when to use it versus alternatives, nor any exclusions or prerequisites. Usage is implied but not clearly outlined.
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, destructiveHint=false, idempotentHint=true. The description adds behavioral context by specifying that the data is forward-test (not backtest), which informs the agent about the nature of the metrics. 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?

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 zero parameters and no output schema, the description adequately covers the tool's return value (specific performance metrics) and data type (forward-test). It could mention update frequency or time range, but this is not critical given the sibling tool for reports likely provides more detail.
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 no parameters, so the description carries the full burden of explaining what the tool returns. It lists specific metrics (win rate, average return, Sharpe ratio) and clarifies the data type (forward-test), adding meaning beyond the empty 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 'AI stock pick performance metrics', listing specific metrics (win rate, average return, Sharpe ratio). It distinguishes from the sibling 'get_ai_performance_reports' by implying this is a summary vs. detailed reports, and clarifies it's forward-test data, not backtest.
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 notes 'Forward-test data (not backtest)', guiding agents on when to use this tool for real performance metrics vs. backtest data. However, it does not explicitly mention alternatives like 'get_ai_performance_reports' for more detailed reports, though the context and naming suggest differentiation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
