Tool Scores

• set_alertD
  1.3/5.0
  Behavior1/5

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

  The behavioral transparency section is detailed but directly contradicts the tool's name and likely intent. It states the tool is read-only and idempotent, whereas 'set_alert' implies a write operation. This contradiction undermines trust.

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

  Conciseness2/5

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

  The description is lengthy with verbose behavioral details, but the core purpose is unclear. The 'Args' section duplicates the schema without adding value. Not front-loaded; key contradictions appear early.

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

  Completeness1/5

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

  Given the output schema exists (not shown), the description still fails to explain what the tool does with the alert. It claims to be an analysis tool, but naming suggests alert creation. Incomplete and contradictory.

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

  Parameters1/5

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

  The 'Args' section merely repeats parameter names and default values without adding meaningful context. With 0% schema description coverage, the description fails to explain how the parameters relate to setting an alert or what valid inputs are.

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

  Purpose1/5

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

  The name 'set_alert' implies creating or modifying an alert, but the description claims the tool is read-only and produces analysis output without modifying any systems. This contradiction severely misleads the agent about the tool's core purpose.

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

  Usage Guidelines2/5

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

  The description includes 'When to use' and 'When NOT to use' sections, but the guidance is generic and does not differentiate this tool from siblings like 'get_alerts' or 'track_mention'. It suggests using for structured analysis, which doesn't align with the name 'set_alert'.

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

• add_competitorC
  2.5/5.0
  Behavior3/5

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

  The description details behavior: read-only, stateless, idempotent, rate limits, error handling, and data privacy. This adds value beyond the missing annotations. However, the fundamental behavioral claim (read-only) contradicts the tool's name and implied action ('add'), creating confusion and reducing trust.

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

  Conciseness3/5

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

  The description is structured with clear headings (Behavior, When to use, Args, etc.) but is verbose and repetitive. For instance, behavioral details appear in both the 'Behavior' section and the 'Behavioral Transparency' section. A more concise version would improve clarity.

  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?

  Although the description covers behavioral aspects thoroughly, it fails to resolve the core contradiction between the tool name ('add') and its declared read-only behavior. With no output schema and four parameters, the tool's complete expected behavior remains ambiguous, especially regarding what 'add' means in a read-only 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 lists parameters with generic phrases like 'The name to analyze or process' without adding specific context, constraints, or examples beyond the schema. Schema coverage is 0%, so the description does not compensate effectively; it merely repeats the param names.

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

  Purpose2/5

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

  The tool name 'add_competitor' suggests creating or adding a competitor record, but the description claims it is read-only and stateless, performing analysis instead. The purpose is unclear and contradictory, making it hard for an agent to understand what the tool actually does.

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

  Usage Guidelines3/5

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

  The description provides when to use (structured analysis) and when not to use (real-time decision-making without review). However, it does not differentiate from sibling tools like 'analyze_sentiment_trend' or 'get_competitor_info', nor does it explain why this tool is preferred over alternatives. The guidance is present but generic.

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

• update_pricingC
  2.8/5.0
  Behavior3/5

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

  The description extensively details side effects, authentication, rate limits, error handling, and idempotency, compensating for missing annotations. However, the contradiction between the name and read-only behavior reduces trust.

  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 well-structured with headings but repeats information (e.g., behavioral transparency details appear twice). Could be more concise.

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

  Completeness2/5

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

  Despite the presence of an output schema, the description does not describe the return value structure or content. It also fails to address the contradiction between the tool name and described behavior.

  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?

  Each parameter is listed with a generic description (e.g., 'The competitor name to analyze or process'), which adds meaning beyond the schema field names but lacks specificity about expected values or constraints.

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

  Purpose2/5

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

  The tool name 'update_pricing' suggests modifying pricing data, but the description states it is read-only and stateless, performing analysis without modifying external systems. This contradiction undermines clarity.

  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 includes explicit 'When to use' and 'When NOT to use' sections, providing clear guidance on appropriate contexts (structured analysis) and exclusions (real-time decisions).

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

• get_alertsC
  2.9/5.0
  Behavior5/5

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

  With no annotations provided, the description carries full burden and covers side effects (read-only), authentication, rate limits, error handling, idempotency, and data privacy. This is thorough and transparent, compensating for the missing annotations.

  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 lengthy and includes repetitive sections (e.g., behavioral transparency repeats side effects and rate limits from earlier). It could be more concise and front-loaded with the core purpose.

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

  Completeness2/5

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

  Despite having an output schema, the description fails to explain what 'active alerts' are or how the output is structured. The generic analysis framing leaves significant gaps in understanding the tool's actual 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?

  The only parameter 'api_key' is described as 'The api key to analyze or process', which is vague and does not clarify its role in getting alerts. Schema coverage is 0%, and the description adds minimal value, leading to confusion about its purpose.

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

  Purpose2/5

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

  The description starts with 'Get active alerts' but then describes a tool for 'structured analysis or classification of inputs against established frameworks or standards'. This is a mismatch and confuses what the tool actually does. It does not clearly distinguish from siblings like 'set_alert'.

  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 explicitly states when to use ('structured analysis or classification') and when not ('real-time production decision-making without human review'). However, the guidance is generic and not specific to alerts, so it provides limited actionable context.

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

• analyze_sentiment_trendB
  3.4/5.0
  Behavior5/5

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

  With no annotations provided, the description carries the full burden and delivers comprehensive detail: read-only, stateless, idempotent, authentication requirements, rate limits (free 10/day), error handling, and data privacy. The 'Behavioral Transparency' section is thorough and leaves no ambiguity about side effects or safety.

  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 clear sections (Behavior, When to use, Args, Behavioral Transparency) and front-loads the purpose. However, there is redundancy between the 'Behavior' and 'Behavioral Transparency' sections that could be merged for 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 output schema exists, the description does not need to detail return values. It covers authentication, rate limits, errors, and idempotency. However, it lacks specificity about what 'sentiment trends' analysis actually produces (e.g., scores, time series) and the 'When to use' section is too generic to fully contextualize the tool's role among siblings.

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

  Parameters2/5

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

  Schema description coverage is 0%, so the description must add meaning beyond parameter names. The 'Args' section only restates the names with generic phrases ('The competitor name to analyze or process') and adds no further semantics like format, constraints, or behavior. This fails to compensate for the missing schema descriptions.

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

  Purpose3/5

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

  The description starts with 'Analyze sentiment trends' which gives a clear verb and resource, but then becomes generic ('structured analysis or classification of inputs against established frameworks or standards'). It does not explicitly differentiate from sibling tools like get_mentions or get_competitor_comparison, leaving the specific purpose somewhat vague.

  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 includes explicit 'When to use' and 'When NOT to use' sections, but the advice is generic ('structured analysis or classification') and does not reference sibling tools or provide specific context for when to choose this tool over alternatives. The exclusion ('not for real-time production decision-making') is helpful but still lacks comparative guidance.

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

• get_competitor_infoA
  3.5/5.0
  Behavior5/5

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

  With no annotations provided, the description fully discloses read-only, stateless, idempotent nature, authentication requirements, rate limits, error handling, and data privacy. This is comprehensive and exceeds typical transparency.

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

  Conciseness3/5

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

  Well-structured with clear sections, but overly verbose—e.g., repeating 'No authentication required for basic usage' in two places. Front-loads purpose well, but could be shorter.

  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?

  Output schema exists but description doesn't hint at what competitor info includes (e.g., name, metrics). Behavioral transparency is thorough, but missing specifics about the tool's domain (competitor analysis) and return format.

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

  Parameters2/5

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

  Schema description coverage is 0%, so the description should compensate. The 'Args' section lists param names with generic descriptions ('The competitor id to analyze or process') that add little meaning beyond the schema. Missing details like default behavior for api_key or valid values.

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

  Purpose3/5

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

  The title 'Get competitor details' is clear, but the description adds 'structured analysis or classification' which muddies the purpose. It doesn't differentiate from siblings like get_competitor_comparison or get_market_share_estimate, making it unclear what specific info is retrieved.

  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?

  Explicit 'When to use' and 'When NOT to use' sections provide good guidance—use for analysis, not for real-time decisions without human review. However, no direct comparison with sibling tools to guide selection.

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

• get_pricing_historyA
  3.5/5.0
  Behavior5/5

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

  With no annotations provided, the description carries full burden and excels. It explicitly states the tool is read-only, stateless, idempotent, safe to retry, and details authentication requirements, rate limits, error handling, data privacy, and lack of side effects. This is comprehensive and leaves no ambiguity.

  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 well-structured with clear sections, but it is overly verbose with redundancy (e.g., 'Behavior' and 'Behavioral Transparency' overlap). The 'When to use' section feels out of place for this tool, and the 'Args' section is unnecessarily wordy for providing tautological descriptions. It could be trimmed without losing value.

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

  Completeness3/5

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

  While behavioral transparency is thorough, parameter semantics are weak, and the 'When to use' guidance is generic and not tool-specific. Given 3 optional parameters with no descriptions, and an output schema that likely documents return values, the description leaves gaps in understanding how to construct inputs. Overall, it meets minimum viability but has clear gaps.

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

  Parameters2/5

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

  Schema description coverage is 0%, so the description must compensate. The 'Args' section lists each parameter (competitor_name, product, api_key) but gives identical generic descriptions ('The ... to analyze or process'), adding no real meaning beyond the parameter name. This is a significant gap, as the agent cannot infer the expected format or 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?

  The tool name 'get_pricing_history' and the first line 'Get competitor pricing history' clearly state the verb and resource. However, the 'When to use' section is generic ('structured analysis or classification') and does not directly tie to pricing history, which slightly dilutes clarity. Nonetheless, the primary purpose is clear enough for an agent to understand what the tool does.

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

  Usage Guidelines3/5

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

  The description includes explicit 'When to use' and 'When NOT to use' sections, which is good. However, the 'When to use' guidance is too generic ('when you need structured analysis or classification') and does not differentiate this tool from siblings like 'get_competitor_comparison' or 'analyze_sentiment_trend'. No alternatives are mentioned, so the guidelines are not fully helpful for selection.

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

• get_competitor_comparisonA
  3.6/5.0
  Behavior5/5

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

  Description includes a dedicated 'Behavioral Transparency' section covering side effects, authentication, rate limits, error handling, idempotency, and data privacy with concrete details (e.g., rate limit headers, idempotency guarantees). This fully compensates for absence of annotations.

  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?

  Well-structured with clear section headers, but contains redundancy between 'Behavior' and 'Behavioral Transparency' sections. Could be shortened without losing key information.

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

  Completeness2/5

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

  Despite detailed behavioral info, the description lacks specifics about output structure (output schema exists but not described) and parameter constraints (e.g., format of competitors). Sibling tools suggest this is a core tool, yet it remains incomplete for effective invocation.

  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 coverage, description must explain parameters. The 'Args' section provides generic one-liners that add little value. Moreover, there is inconsistency: the description mentions authentication via environment variable, yet the schema has an 'api_key' parameter with empty default, causing confusion.

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

  Purpose4/5

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

  The title 'get_competitor_comparison' and first line 'Compare competitors' clearly indicate the tool's core function. However, the additional description about 'structured analysis or classification against frameworks' is somewhat vague and does not fully distinguish from siblings like 'get_competitor_info' or 'analyze_sentiment_trend'.

  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?

  Explicit 'When to use' and 'When NOT to use' sections provide contextual guidance, including a warning about real-time decision-making. However, it lacks direct comparison to sibling tools and does not specify prerequisites like data availability.

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

• track_mentionA
  3.7/5.0
  Behavior5/5

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

  With no annotations provided, the description carries full responsibility and excels: it details side effects, authentication, rate limits, error handling, idempotency, and data privacy. This is comprehensive and helpful.

  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 well-structured but contains redundancy (e.g., overlapping 'Behavior' and 'Behavioral Transparency' sections). It could be shorter without losing key information.

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

  Completeness3/5

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

  Covers behavioral aspects well but lacks parameter semantics and sibling differentiation. Given 5 parameters and an output schema, the description is somewhat complete but missing critical parameter guidance.

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

  Parameters2/5

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

  Schema description coverage is 0%, so the description must compensate. It lists each parameter with a generic label (e.g., 'The competitor name to analyze or process') that adds almost no meaning beyond the parameter name. No formats, constraints, or examples are given.

  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 'Track a competitor mention' and provides structured analysis. However, it does not differentiate from sibling tools like 'get_mentions' or 'analyze_sentiment_trend', which may 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 Guidelines4/5

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

  Explicit 'When to use' and 'When NOT to use' sections are present. It advises using for structured analysis and cautions against real-time use without human review, but lacks specific comparisons to siblings.

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

• get_mentionsA
  3.9/5.0
  Behavior5/5

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

  With no annotations provided, the description fully discloses behavioral traits: read-only, stateless, idempotent, rate limits, authentication requirements, error handling, and data privacy. This level of detail is exemplary and adds significant 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?

  Well-structured with clear sections (Behavior, When to use, Args, Behavioral Transparency). However, the Args section is repetitive (all parameters described identically) and could be more concise. Overall, front-loaded with key info.

  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?

  Covers purpose, behavior, usage guidance, parameters (despite weak descriptions), and behavioral transparency. With 4 parameters and an output schema, the description provides adequate context for most use cases, though parameter details could be richer.

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

  Parameters2/5

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

  Schema description coverage is 0%, so the description must compensate. The 'Args' section provides generic descriptions (e.g., 'The competitor name to analyze or process') that add minimal meaning beyond the parameter names. No details on valid values, formats, or constraints.

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

  Purpose4/5

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

  Description clearly states 'Get mentions for competitor' with a specific verb and resource. While not explicitly differentiating from siblings like get_competitor_info or get_competitor_comparison, the purpose is direct and unambiguous.

  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?

  Includes 'When to use' and 'When NOT to use' sections, providing context for when the tool is appropriate (structured analysis/classification) and cautioning against real-time decision-making without human review. However, the use cases could be more tailored to 'mentions' rather than generic analysis.

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

• get_market_share_estimateA
  4.1/5.0
  Behavior5/5

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

  With no annotations provided, the description carries full burden and excels: it declares read-only, stateless, idempotent behavior, specifies rate limits (free/pro), authentication details, error handling, and data privacy. This is comprehensive and beyond minimal.

  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 well-structured with sections but contains significant repetition (e.g., read-only behavior stated in 'Behavior', 'Args', and 'Behavioral Transparency'). Could be pruned to be more concise.

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

  Completeness4/5

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

  For a simple two-parameter tool with an output schema, the description covers behavior, errors, and privacy well. However, it lacks details on the output structure and parameter specifics, leaving minor gaps.

  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 schema description coverage is 0%, so the description must compensate, but the 'Args' section only repeats parameter names with vague phrases like 'to analyze or process'. It does not explain valid values, formats, or examples, leaving parameters poorly defined.

  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 'Estimate market share' as the core function, with a specific verb ('estimate') and resource ('market share'). It differentiates from siblings like 'get_competitor_comparison' by focusing on market share estimation.

  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 includes explicit 'When to use' and 'When NOT to use' sections, advising structured analysis and caution against real-time decisions without human review. However, it does not name alternative sibling tools for similar tasks.

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