Server Quality Checklist

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

Latest release: v0.7.1
Disambiguation3/5
Many tools have overlapping purposes (multiple scanners, multiple analysis tools), but detailed descriptions help differentiate them. Some tools like 'bollinger_scan' and 'rating_filter' serve distinct niches, but the high count makes it easy for an agent to pick the wrong one.
Naming Consistency2/5
Naming conventions are inconsistent: some use verb_noun (e.g., 'bollinger_scan'), others use noun_verb (e.g., 'volume_breakout_scanner'), and some are descriptive phrases (e.g., 'stock_options_unusual_activity'). No uniform pattern is followed.
Tool Count2/5
With 37 tools, the server feels overloaded. Many tools serve similar purposes (e.g., multiple scanners, multiple backtest variants), and the scope could be consolidated into a more focused set.
Completeness4/5
The tool set covers a wide range: scanning, detailed analysis, backtesting, market overview, news sentiment, and options. Missing areas like trade execution or portfolio management are likely out of scope, so the coverage is strong for its domain.
Average 3.8/5 across 37 of 37 tools scored. Lowest: 2.6/5.

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

Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It lacks details on side effects, authentication needs, or return behavior. The description merely parameterizes the analysis without disclosing any 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.
Conciseness3/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description uses a structured docstring format with parameter list, which aids readability. However, it is slightly verbose for the content delivered, and the 'Args' block could be integrated into a more concise narrative.
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 five parameters and no output schema, the description should clarify return format and tool behavior. It does not explain what 'analysis' produces (e.g., list of patterns, scores). The minimal parameter descriptions leave gaps in understanding full functionality.
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?
With 0% schema description coverage, the description must add meaning. It provides brief explanations for each parameter (e.g., min_size_increase is a percentage), but these are minimal and do not clarify how parameters affect pattern detection. For instance, what constitutes a pattern_length of 2 vs 4?
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 performs 'Advanced candle pattern analysis using multi-timeframe data', specifying the task and resource. However, it could be more precise about what patterns are detected, keeping it from a perfect score.
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 siblings like 'consecutive_candles_scan' or 'bollinger_scan'. The description only lists parameters without context on appropriate use cases.
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?
No annotations are provided, so the description must disclose behaviors. It only says 'analysis' without indicating read-only status, data requirements, side effects, or any limitations. For a tool performing analysis, this is insufficient.
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 brief, but it lacks structure beyond a one-line purpose and an argument list. It could be more organized, but it is not verbose. The conciseness comes at the cost of completeness.
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 or annotations, the description should cover return values, interpretation, and constraints. It does not explain what 'volume confirmation analysis' entails or what the output looks like, leaving the agent without crucial context.
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's Args block merely restates parameter names with examples, adding no meaning beyond the schema. With 0% schema description coverage, it fails to explain allowed values, formats, or constraints (e.g., symbol format, valid timeframes).
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 it performs 'Detailed volume confirmation analysis for a specific coin', which clearly identifies the verb (analysis) and resource (coin). However, it does not differentiate from sibling tools like 'volume_breakout_scanner' or 'smart_volume_scanner', which may also involve volume 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 on when to use this tool versus alternatives. It does not mention prerequisites, typical use cases, or when not to use it. The description is purely functional.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Behavior1/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations exist, and the description fails to disclose behavioral traits such as read-only nature, data freshness, error conditions, or performance implications for large 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 a short sentence plus an Args section. It is front-loaded and efficiently structured, though the Args section adds minimal formatting.
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 3 parameters, no output schema, and no annotations, the description omits return format, data freshness, and error handling. It is adequate for basic use but incomplete for nuanced scenarios.
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?
Despite 0% schema coverage, the description lists valid values for index and timeframe, and explains limit meaning (number of stocks, max 100). This adds beyond the schema's defaults but does not clarify what 'full indicators' entails.
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 the action 'analyse' and resource 'EGX index', specifying output as 'constituent performance with full indicators'. This clearly differentiates from sibling EGX tools like egx_market_overview or egx_sector_scan, though 'full indicators' is vague.
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. Among many EGX-related siblings, no comparator or exclusion criteria are provided.
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?
With no annotations, the description must disclose behavioral traits. It mentions 'licensed Marketaux entity sentiment' but does not cover data freshness, rate limits, error behavior, or whether it is read-only. This leaves significant gaps.
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 with a clear one-line summary followed by parameter explanations in a structured Args block. Every sentence adds value, though it could be more compact.
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 explain return values and any limitations. It does not describe the sentiment format (e.g., score range) or how analysis is performed. This is incomplete for an intelligent 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 description coverage is 0%, so the description adds basic meaning for each parameter: symbol examples, category options, and limit as max articles. This is helpful but minimal; no format constraints or validation rules 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 clearly states the tool provides 'news sentiment for stocks and crypto', which is a specific verb and resource. It is distinct from siblings like 'financial_news' which likely provides raw news, but it 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 on when to use this tool versus alternatives. It does not describe prerequisites, use cases, or exclusions, leaving the agent to infer usage from 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?
No annotations are provided, so the description must disclose behavioral traits. It only states the tool 'identifies' data without mentioning read-only nature, permissions, or side effects. Minimal disclosure.
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 a clear opening sentence and an organized list of parameters. Every sentence adds value without redundancy.
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, yet the description fails to describe the return format (e.g., whether output lists sectors with scores). For a scanning tool, this gap reduces 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?
The description adds meaningful details for each parameter, including acceptable ranges and defaults (e.g., timeframe options like 5m, 15m). This goes beyond the schema's titles and defaults, providing clear value.
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 is a sector rotation scanner for EGX that identifies hot/cold sectors and top picks, providing a specific verb and resource. However, it does not differentiate from sibling tools like 'egx_sector_scan'.
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 'egx_sector_scan' or 'egx_stock_screener'. The description lacks contextual cues for selection.
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?
No annotations are provided, so the description must fully convey behavioral traits. It states 'comprehensive overview' but omits that the operation is read-only, does not describe the response structure, and lacks any mention of rate limits, permissions, or potential 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 extremely concise: one sentence for purpose followed by a brief parameter list. No fluff or redundant information. The structure is clean 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?
The description adequately defines the two parameters but lacks any mention of the output format or the specific data returned by the 'comprehensive overview'. Without an output schema, the agent cannot infer what to expect from the tool's response. Additional context about scope (e.g., does it cover all EGX listed stocks?) 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?
The description adds significant meaning beyond the schema by listing allowed values for 'timeframe' (5m, 15m, 1h, 4h, 1D, 1W, 1M), specifying defaults (1D for stocks), and noting the maximum for 'limit' (20). This compensates well for the schema's 0% description coverage, though explicit enum formatting would be clearer.
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 target resource ('Egyptian Exchange (EGX) market') and the action ('Get a comprehensive overview'). However, it does not specify what facets of the market are included (e.g., indices, sectors, top stocks), which would help differentiate it from siblings like 'egx_index_analysis' or 'egx_sector_scan'.
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 over alternatives. With many sibling tools focused on EGX (egx_index_analysis, egx_sector_scan, egx_stock_screener) and general market overviews (futures_market_overview), users receive no context about the appropriate selection criteria.
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?
With no annotations, the description must disclose behavioral traits. It mentions that results are limited to 50 per sector and that leaving sector empty shows all sectors, but it lacks details on data source, freshness, error handling, or side effects, leaving significant gaps.
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 and well-structured: a single-sentence purpose followed by a clear 'Args:' section with each parameter explained. 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 absence of annotations and output schema, the description covers parameter details and basic purpose. However, it lacks information about the output format, sorting, or how results relate to the sibling 'egx_sector_scanner', leaving some contextual 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?
All three parameters are explained in the description with examples and constraints (e.g., sector names, timeframe values, limit max). Since the schema had no descriptions (0% coverage), the description effectively compensates by adding meaning 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 that the tool scans EGX stocks by sector and lists sectors if none specified. However, it does not differentiate from the similarly named sibling 'egx_sector_scanner', leaving the agent unsure which to use.
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 only hints at usage by noting that leaving sector empty lists sectors, but it provides no explicit guidance on when to use this tool vs alternatives, nor 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.
Behavior2/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description must carry the burden. It mentions 'real-time' but does not elaborate on frequency, restrictions, rate limits, or any other behavioral characteristics.
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 and front-loaded with the main purpose. Every sentence is meaningful, with 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?
For a simple one-parameter tool with no output schema, the description covers the core purpose and parameter examples. It lacks mention of output format or error handling, but is reasonably 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 0% (no description in schema). The description compensates well by providing concrete examples for different asset types (e.g., AAPL, BTC-USD, ^GSPC, THYAO.IS), clarifying the symbol format.
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 a real-time price quote from Yahoo Finance for stocks, crypto, ETFs, or indices. The verb is implicit but the resource and action 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 guidance on when to use this tool versus alternatives like stock_prices or coin_analysis. The description lacks context for selection among many sibling 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?
With no annotations, the description bears full burden for behavioral disclosure. It fails to explain what a 'full trade plan' entails (e.g., entry, exit, risk parameters), whether it requires internet access, or any side effects. Minimal behavioral detail is provided.
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, starting with the main purpose in one line, followed by a clean list of arguments. No unnecessary words, and the structure is easy to scan.
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 adequately covers the parameters, but lacks information about the output (what a trade plan contains) and any usage context (e.g., prerequisites, limitations). Given the absence of an output schema, the description should ideally describe the return format.
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 0%, so the description compensates well by explicitly listing valid timeframe values (5m, 15m, 1h, etc.) and providing example symbols for the symbol parameter. This adds significant meaning beyond the bare 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 generates a full trade plan for a specific EGX stock, using a specific verb and resource. It distinguishes from sibling tools like egx_index_analysis or egx_market_overview, which cover broader scopes.
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 scenarios where it is appropriate or inappropriate, nor does it reference sibling tools for 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?
With no annotations, the description carries the full burden. It discloses parameter details including defaults and a specific constraint for certain strategies, but does not mention the return format, error behavior, or whether the operation is read-only. The phrase 'institutional-grade metrics' is vague and lacks specifics, 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.
Conciseness4/5
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is well-structured with an Args section and bullet-like parameter list. It is concise but includes necessary details. Minor reduction for not being even more succinct, e.g., removing redundant 'Args:' header.
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 9 parameters and no output schema, the description covers all inputs adequately but fails to explain the output (return values, metrics). For a complex tool, this is a significant gap. The inclusion of parameter defaults and strategy-specific notes helps, but missing output details reduces completeness.
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 description adds substantial meaning beyond the input schema, which has 0% coverage. It provides example values for symbol (e.g., AAPL, BTC-USD), lists all strategy options with enum-like clarity, and explains defaults for numeric parameters. This fully compensates for the schema's lack of 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's purpose: backtesting a trading strategy on historical data with institutional-grade metrics. It provides a verb (Backtest) and specific resource (trading strategy + historical data). While it distinguishes from sibling tools like compare_strategies by focusing on single strategy backtesting, it does not explicitly differentiate from walk_forward_backtest_strategy, leaving some 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?
The description lacks explicit guidance on when to use this tool versus alternatives. It only provides a constraint note for rsi_pullback and triple_ema strategies needing period >= '1y'. No mention of when not to use it, prerequisites, or comparison with sibling tools like compare_strategies or walk_forward_backtest_strategy.
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?
No annotations provided, so description carries full burden. It mentions 'Powered by Yahoo Finance' indicating data source. However, it does not disclose refresh rate, data freshness, or any limitations. Scope is defined but behavioral traits are 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?
Two sentences: one functional description and one source attribution. No wasted 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 zero parameters and no output schema, the description adequately explains what the tool returns (major indices, crypto, FX, ETFs). It is sufficient for an agent to understand the tool's product, though more details on specific items would enhance 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?
No parameters exist, and schema coverage is 100% (trivially). Baseline 4 is appropriate since description adds no extra param info 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?
Description clearly states it provides a global market overview covering major indices, top crypto, FX rates, and key ETFs. It is specific about the resource but could be more action-oriented (e.g., 'Retrieve'). Distinguishes from siblings like bitcoin_market_pulse or futures_category_snapshot by being a broad snapshot.
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. Among many sibling market tools, the description lacks context for selection.
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?
No annotations are present, so the description must carry full behavioral disclosure. It only says 'analysis' without indicating whether it is read-only, what output to expect, or any side effects. This is insufficient for understanding the tool's behavior.
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-loads the core purpose. However, the 'Args:' section is somewhat mechanical and could be integrated more naturally. Overall, it is efficient with 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?
The description adequately explains the three input parameters but does not describe the output or the nature of the retracement analysis (e.g., levels, percentages). Given no output schema, more detail on return values 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?
The input schema provides 0% description coverage. The description compensates by listing allowed values and defaults for 'lookback' and 'timeframe' (e.g., '1M', '3M', '52W', 'ALL' and '5m', '15m', '1h', etc.). The 'symbol' parameter is described simply as 'EGX stock symbol,' which is basic but adds some context.
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 performs 'Fibonacci retracement analysis for EGX stocks,' specifying the analysis type and market. It distinguishes well from sibling tools, none of which duplicate this function.
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 for technical analysis of EGX stocks but provides no explicit guidance on when to use it versus other analysis tools or alternatives. No exclusions or prerequisites are mentioned.
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?
No annotations are provided, so the description carries the full burden. It mentions 'Real-time' and 'licensed' but does not disclose behavioral traits like read-only nature, rate limits, pagination, or data freshness. The description lacks detail on what happens if no news is found or if the source is unavailable.
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 purpose. The Args section is clearly formatted inline. While concise, it could be slightly more structured (e.g., bullet points), but it serves its purpose without unnecessary 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?
With 3 parameters and no output schema, the description covers the parameters adequately but lacks details on return format (e.g., what fields each news item contains), pagination, or error handling. Given the tool's simplicity, it is minimally viable but has clear 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 0%, so the description must provide meaning. It explains each parameter: symbol ('Optional symbol filter... None = all news'), category ('News category...'), limit ('Max number of news items'). This adds significant context beyond the schema's type and default values.
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 'Real-time financial news via Marketaux (licensed).' It specifies the resource (financial news), verb (implied get), and source. Among many sibling tools focused on technical analysis or market data, this is the only news tool, making its purpose distinct.
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 parameters and their defaults, providing context for usage (e.g., filter by symbol, category, limit). However, it gives no explicit guidance on when to use this tool versus alternatives or when not to use it. The context of sibling tools being mainly technical analysis implies but does not specify 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?
With no annotations provided, the description carries the full burden of behavioral disclosure. It states the tool returns OHLCV quotes, implying a read-only operation, but does not discuss potential side effects, authentication needs, or rate limits. The description is adequate but lacks depth.
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 a clear first sentence defining the purpose, followed by Args and Returns sections. It is concise but could be slightly tighter (e.g., the example symbols list, while helpful, adds length). Overall, it earns its brevity.
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, returns OHLCV quotes), the description covers purpose, parameters, and return type without needing an output schema. It lacks details on pagination or limits, but for a snapshot tool this is acceptable.
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 0%, so the description must compensate. It enumerates valid categories (equity_index, energy, etc.) and provides example symbols, adding significant meaning beyond the schema's minimal 'string' type. However, it does not specify the default value or format expectations beyond examples.
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 that the tool quotes all major front-month contracts in a specific futures category, with the verb 'quote' and resource 'futures category snapshot'. It provides a clear list of categories and example symbols. However, it does not explicitly differentiate from sibling tools like 'futures_market_overview' or 'futures_watchlist', which could have similar 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 implies usage when needing OHLCV quotes for a category of futures, but it lacks explicit guidance on when to use this tool versus alternatives. No exclusions or preferred contexts are mentioned, leaving the agent to infer usage from the tool's name and description 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?
No annotations are provided, so the description carries full burden. It discloses return type (list[dict]) and error envelope on total failure, and mentions inheritance from inner call. However, it does not state whether the tool is read-only or destructive, nor any rate limits or auth requirements.
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 structured as a docstring with clear Args and Returns sections, making it easy to parse. The first sentence is concise, but the full docstring is somewhat verbose. It could be more compact without losing 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?
Given 5 optional parameters and an output schema (not shown), the description covers parameters and the return value structure, including error cases. It does not explain the contents of the returned list[dict] (likely covered by output schema), but missing usage context relative to sibling scanners.
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 description coverage is 0%, so the description must compensate. It provides clear explanations for all 5 parameters, including types, defaults, and allowed values (e.g., rsi_range options 'oversold', 'overbought', 'neutral', 'any'). It also adds constraints like limit max 30, which is not 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?
The description clearly states it's a combination scanner of volume and technical analysis (RSI). It specifies the verb 'scanner' and the resource, but doesn't explicitly use a verb like 'scan' and doesn't differentiate from siblings such as volume_breakout_scanner or bollinger_scan.
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. Siblings like volume_breakout_scanner likely serve a similar purpose without RSI filtering, but the description does not help the agent choose.
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?
No annotations are provided, and the description does not disclose behavioral traits beyond basic function. It does not mention read-only nature, rate limits, data freshness, or any side effects. For a production tool, this is a significant gap.
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 purpose sentence and a bulleted parameter list. It is front-loaded and contains no wasted words, making it easy to scan.
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 adequately covers parameters but lacks output description (e.g., what the results look like) and usage context among many similar sibling tools. Given no output schema, more detail on return values 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?
With 0% schema description coverage, the description fully explains all 4 parameters: timeframe options, min_score range, index_filter values, and limit max. This adds substantial meaning beyond the schema, though could include data types or examples.
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 is a stock ranking engine for EGX that finds strong stocks with actionable setups. This distinguishes it from similar sibling tools like 'stock_screener' by specifying the EGX market and using the term 'ranking engine'.
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 EGX stock screening but does not explicitly state when to use this tool versus alternatives like 'stock_screener' or 'egx_index_analysis'. 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.
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so the description carries the full burden. It describes parameters but doesn't mention side effects, rate limits, or data freshness. For a read-only scan, this is adequate but could be improved.
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-line purpose followed by a clean bullet list of parameters. Every sentence adds value, no fluff. 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?
No output schema, but the return behavior (list of matching coins) is implied. The description could specify ordering or result details, but for a simple scanner it is reasonably 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 description coverage is 0%, but the description lists all 6 parameters with concise explanations (e.g., 'pattern_type: bullish (growing candles) or bearish (shrinking candles)'), adding meaning beyond the schema's titles and defaults.
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 'Scan for coins with consecutive growing/shrinking candles pattern,' providing a specific verb (scan), resource (coins), and pattern type. This differentiates it from sibling tools like 'advanced_candle_pattern' or 'bollinger_scan'.
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 gives parameter details but does not provide guidance on when to use this tool vs. alternatives. With many sibling scanners, explicit context for selection is lacking.
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?
No annotations provided, so description carries full burden. It discloses return format (Dict with total_available and list of contracts with OHLCV + % change) but does not mention whether the operation is read-only, rate limits, or side effects. Adequate but not thorough.
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?
Reasonably concise, with clear Args/Returns structure. The parameter enumeration is a bit lengthy but appropriate for clarity. No superfluous sentences.
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 covers return structure and parameter details. However, it does not address how this tool fits among many siblings, slightly reducing completeness.
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 description coverage is 0%, yet the description fully explains all four parameters: category with enumerated values, exchanges with regional mapping, limit with default, volume_min with meaning. This provides rich semantics beyond the bare 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 states 'Top futures contracts sorted by trading volume', clearly specifying the verb (list/sort) and resource (futures contracts). It distinguishes from siblings like futures_category_snapshot by focusing on volume-based ranking.
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 such as futures_top_movers or futures_watchlist. The description only lists parameters, leaving the agent to infer 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?
With no annotations provided, the description adequately discloses the return type ('list[dict]' or an error envelope) and the filtering behavior. However, it does not mention any side effects, rate limits, permissions, or whether the operation is read-only, which are important for safe invocation.
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 front-loaded with the purpose and uses a clear structured format (Args section) for parameters. It is reasonably concise, though the parameter list could be slightly more compact without losing 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?
Given the output schema existence and the tool's straightforward nature, the description covers the essential aspects: purpose, parameters, return type, and error handling. It could improve by specifying that it targets cryptocurrency markets, but the exchange examples imply this context.
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?
Despite 0% schema description coverage, the Args section thoroughly explains all four parameters: exchange (with example values), timeframe (list of options), rating (with rating scale), and limit (max 50). It adds substantial meaning beyond the schema's defaults and types.
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 'Filter coins by Bollinger Band rating,' which is a specific verb-resource pair. It clearly differentiates from siblings like 'bollinger_scan' by focusing on rating-based filtering rather than pattern scanning.
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 'bollinger_scan' or 'coin_analysis.' It lacks explicit context about prerequisites or ideal use cases, leaving the agent to infer usage from parameter details alone.

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 complexity (9 parameters, no annotations, no output schema), the description covers inputs well but omits any description of the output. An agent selecting this tool needs to know what it returns (e.g., metrics, fold results) to decide if it suits the task. This gap reduces completeness.
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 description provides thorough explanations for all 9 parameters, including allowed values (e.g., strategy enum, period formats), defaults, and recommendations. Since the input schema has 0% description coverage, the description fully compensates by adding essential meaning beyond property titles.

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 core function: 'Walk-forward backtest to detect overfitting — validates strategy on unseen data.' This is a specific verb-resource pair. However, it does not explicitly differentiate from sibling backtest tools like backtest_strategy, leaving the agent to infer when to choose this over alternatives.
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 lists two strategies (rsi_pullback, triple_ema) that are NOT supported in this tool and directs users to 'use run_backtest with period='2y'' instead. This provides clear when-not-to-use guidance. However, it lacks a general statement about when to prefer walk-forward over a standard backtest.
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?
No annotations provided, so description carries full burden. It explains it is a read operation returning a list of futures with OHLCV data, and details parameter defaults like volume_min filtering illiquid contracts. No contradictions, but could mention any auth requirements.
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?
Very concise: one-line summary, Args list with each parameter on one line, and Returns line. Front-loaded with 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?
Given no annotations or output schema, the description explains return type (list with % change and OHLCV) and all parameters with defaults. Missing details like specific return fields or today's data scope, but sufficient for agent use.

Parameters5/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema has 0% description coverage, but the description provides clear explanations for all parameters: direction (gainers/losers), exchanges (us/global), limit (max results), volume_min (minimum volume filter with default 10). Adds meaning 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 it returns 'Futures contracts with the biggest percentage moves today,' specifying the verb (get) and resource (futures top movers). It implicitly distinguishes from stock-focused siblings like top_gainers and top_losers by focusing on futures.
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 (e.g., futures_category_snapshot or futures_market_overview). The description implies usage for top movers but lacks 'when not to use' or explicit comparisons.
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?
No annotations are provided, so the description carries full burden. It does not disclose behavioral traits such as whether the tool is read-only, requires authentication, has rate limits, or any side effects. It only states what it returns, lacking transparency about system interactions.
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 sections (Args, Returns) and an example. It is longer than necessary but each sentence adds value. Minor redundancy: "Detailed analysis with all indicators and metrics" could be more specific.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given 3 parameters, no output schema, and a large sibling set, the description covers all essential aspects: purpose, parameters, usage guidelines, and error behavior. Missing details on return structure or pagination, but adequate for basic usage.
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 0%, yet the description adds comprehensive meaning to all parameters: explains symbol format (crypto vs stock examples), exchange list with error handling hint, timeframe options. This greatly enriches the bare 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 provides detailed analysis for a specific asset on an exchange and timeframe. It distinguishes itself from siblings like multi_timeframe_analysis and combined_analysis, making the purpose unmistakable.

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 only titles and default value, providing no descriptions. The description extensively compensates with detailed explanations for both parameters: symbol (bare ticker, no exchange prefix, with examples across crypto and stocks) and exchange (lists valid values). This far exceeds the schema's minimal information.
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?

Completeness5/5
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
With no output schema, the description thoroughly explains the return format (pre_market, regular, post_market with fields and nullable states) and contextual fields (previous_close, currency, exchange, market_state). It covers edge cases (regular session null, weekends/holidays) and the meaning of each computed percentage change. This is complete for a single-parameter 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 0% description coverage, but the parameter description in the tool description adds significant meaning: 'symbol: US stock symbol — AAPL, NVDA, TSLA, SPY, ^GSPC, etc.' This clarifies acceptable values. However, it could specify whether case matters or include additional format details, which prevents a perfect 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?
The description clearly states the tool provides 'Real-time pre-market and after-hours prices for a US stock symbol.' It specifies the verb (get real-time prices) and resource (extended hours data). The purpose is distinct from siblings like stock_prices (regular hours) and yahoo_price, as it explicitly focuses on pre-market and after-hours sessions.
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 says 'Use this when the user asks about a stock outside the regular 9:30am-4pm ET session' and gives concrete examples: earnings reactions, overnight news, 'what is X doing in after-hours?', 'how did Y open in pre-market?'. It also clarifies when not to use (regular hours). This provides clear guidance for an AI agent.
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?
Despite no annotations, the description fully discloses the tool's behavior: it returns underlying price/change, requested expiry, available expiries, counts, and detailed options data. It also covers error handling for invalid expiry dates.
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 well-structured with a concise introductory paragraph followed by clear Args and Returns sections. Every sentence adds value without redundancy.
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?
The description is complete for the tool's complexity: it covers input constraints, output shape (including nested objects), and edge cases (no expiry, invalid expiry). No additional information is needed for correct usage.
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 descriptions (0% coverage), but the description adds rich meaning: symbol is described as a US stock symbol with examples, and expiry is explained as an optional ISO date that must match Yahoo's available expiries, including error behavior.
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 it returns the full options chain (calls + puts) for a US stock symbol and one expiry. It differentiates from siblings by focusing on the complete chain for a given expiry, and even clarifies behavior when no expiry is provided.
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 provides clear usage examples ('what's the options chain for X?', 'show me AAPL puts expiring next Friday', etc.) and explains the fallback behavior when no expiry is given. It implicitly contrasts with siblings like unusual activity tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
