Tool Scores

• polyrank_get_trader_skillA
  3.5/5.0
  Behavior3/5

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

  Annotations declare readOnlyHint=true and openWorldHint=true. The description adds that some fields are gated behind a paid tier, which is useful behavioral context. However, it lacks details on error handling, authentication, or rate limits.

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

  Conciseness5/5

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

  Two sentences, front-loaded with the main purpose, and no redundant information. Efficient and well-structured.

  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 lists many output metrics but does not specify the response structure (e.g., JSON fields) or how gated fields behave for free vs paid users. Without an output schema, more detail would improve completeness.

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

  Parameters3/5

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

  Schema coverage is 100% and the schema already documents the 'address' parameter with its format. The description does not add additional meaning or examples beyond the schema.

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

  Purpose5/5

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

  The description clearly states it returns a single wallet's skill profile, listing specific metrics (composite rank, P&L, win-rate, etc.), and distinguishes from sibling tools that focus on leaderboards or market consensus.

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

  Usage Guidelines2/5

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

  No explicit guidance on when to use this tool versus alternatives like get_trader_calibration or get_leaderboard. The description does not provide decision context or when not to use it.

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

• polyrank_get_trader_by_tidA
  3.7/5.0
  Behavior3/5

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

  Annotations already declare readOnlyHint=true and openWorldHint=true, and the description adds context about returning a masked skill teaser and the limitation of not providing full identity without signing in. It does not cover error cases or behavior for invalid tids, but is consistent with annotations.

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

  Conciseness5/5

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

  The description is extremely concise with three sentences covering purpose, source of tid, return type, and limitation. Every sentence adds value, and the most important information is front-loaded. No unnecessary words or repetition.

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

  Completeness4/5

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

  Given the tool's simplicity (one parameter, no output schema) and the presence of related sibling tools, the description provides adequate context: what it does, input source, return type, and a key limitation. It could mention error handling or tid validity but overall is sufficient for an agent to use it correctly.

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

  Parameters4/5

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

  The schema already describes the 'tid' parameter as an opaque trader id from a masked row (100% coverage). The description adds value by specifying where the tid originates (leaderboard, pulse, movers, top-ROI rows), which helps agents understand the context of the parameter beyond the schema.

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

  Purpose4/5

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

  The description clearly states the tool looks up a trader by an opaque masked id (tid), specifying the source surfaces (leaderboard, pulse, movers, top-ROI rows). It explicitly distinguishes from wallet lookup and mentions the return type (masked skill teaser), making the purpose clear and specific.

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

  Usage Guidelines3/5

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

  The description explains when to use the tool (when you have a tid from masked rows) and when not (full identity resolution requires signing in). However, it does not explicitly name alternative tools like get_trader_calibration or get_trader_skill for other use cases, leaving some ambiguity.

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

• polyrank_get_top_roi_tradesA
  3.9/5.0
  Behavior4/5

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

  Annotations declare readOnlyHint=true and openWorldHint=true. The description adds context that only resolved, won positions are included, with a real cost floor, and identities are masked. This provides useful behavioral detail beyond what annotations offer, with no contradiction.

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

  Conciseness5/5

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

  The description is two sentences, front-loaded with the core purpose and key details. Every sentence adds value without unnecessary words.

  Completeness3/5

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

  Given 5 parameters, 2 enums, and no output schema, the description covers the core concept and one optional filter but omits return format details, explanation of sort keys, and limit behavior. It is adequate but not fully comprehensive.

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

  Parameters3/5

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

  Schema coverage is 100%, so baseline is 3. The description mentions the category filter but does not add extra meaning for parameters like sort, dir, limit, or since_days. It provides minimal additional value over the schema.

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

  Purpose5/5

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

  The description clearly states the tool returns the biggest return-on-cost resolved Polymarket bets (won positions with a real cost floor), acting as a hall-of-fame of single trades by ROI multiple. This specific verb+resource combination distinguishes it from siblings like leaderboard or pulse.

  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 mentions optional category filtering and identity masking but does not explicitly state when to use this tool versus alternatives like polyrank_get_leaderboard or polyrank_get_trader_skill. Usage context is implied but not elaborated.

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

• polyrank_get_moversA
  4/5.0
  Behavior3/5

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

  Annotations already declare readOnlyHint and openWorldHint, so the description adds limited behavioral detail beyond confirming it returns top movers. No contradictions.

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

  Conciseness5/5

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

  Two concise sentences covering purpose and core parameters without extraneous detail. Efficient and easy to parse.

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

  Completeness4/5

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

  For a read-only tool with full schema coverage and no output schema, the description adequately explains return format (top climbers and fallers) and constraints (preset, lookback). Minor omission: does not specify that limit controls rows per direction, but schema covers that.

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

  Parameters3/5

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

  Schema coverage is 100%, so parameters are well-documented. The description mentions 'ranking preset' and 'lookback window' but adds no additional meaning beyond the schema definitions.

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

  Purpose5/5

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

  The description clearly states the tool returns traders whose skill rank moved (climbers and fallers), specifying 'leaderboard momentum' and differentiating from sibling tools that show static ranks or specific trader skills.

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

  Usage Guidelines4/5

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

  The description implies usage for momentum analysis ('climbed or fell the most recently') but does not explicitly mention when not to use or list alternatives. The context of sibling tools helps narrow usage.

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

• polyrank_get_trader_calibrationA
  4/5.0
  Behavior4/5

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

  Annotations already declare readOnlyHint and openWorldHint. Description adds meaningful behavioral context: explains calibration as skill signal and specifies return data (bins + total resolved count). No contradictions.

  Parameters3/5

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

  Schema coverage is 100% with one parameter well-described. Description adds no additional parameter semantics beyond the schema's definition of address format.

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

  Purpose5/5

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

  Clearly states it returns a 10-bin reliability diagram for a wallet's calibration, distinguishing it from siblings like polyrank_get_trader_skill which likely provides a single skill score. Verb 'get trader calibration' and resource are specific.

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

  Usage Guidelines3/5

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

  No explicit guidance on when to use this tool versus alternatives like polyrank_get_trader_skill. Usage is implied by context (calibration vs. overall skill), but no when-not or alternative mentions.

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

• polyrank_get_market_consensusA
  4.1/5.0
  Behavior3/5

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

  The description adds moderate context beyond the annotations (e.g., 'differentiated signal', specific data fields). However, annotations already declare readOnlyHint and openWorldHint, so the behavioral burden is partially lifted. No contradictions.

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