• clear_cacheC
  2.9/5.0
  Behavior2/5

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

  With no annotations provided, the description carries full burden for behavioral disclosure. 'Clear' implies a destructive operation that removes cached data, but the description doesn't specify what 'clear' entails (e.g., complete wipe, selective removal, irreversible action), whether it requires permissions, or what happens after clearing. It lacks details on side effects or operational constraints.

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

  Conciseness5/5

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

  The description is a single, efficient sentence with zero waste. It's front-loaded with the core action and resource, making it easy to parse quickly. No unnecessary words or structural issues detract from 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?

  Given the tool's complexity (a destructive operation with optional targeting) and lack of annotations or output schema, the description is incomplete. It doesn't explain the outcome (e.g., success confirmation, error handling), the scope of clearing (all vs. specific), or behavioral nuances. For a mutation tool with zero annotation coverage, more context is needed to guide safe and effective use.

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

  Parameters3/5

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

  Schema description coverage is 100%, so the schema already documents both parameters (owner and repo) as optional strings for targeting specific repositories. The description doesn't add any parameter semantics beyond what the schema provides, such as explaining when to use these parameters or the effect of omitting them. Baseline 3 is appropriate when schema does the heavy lifting.

  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 'Clear the documentation cache' clearly states the action (clear) and target (documentation cache). It's specific about what resource is affected, though it doesn't differentiate from sibling tools like 'list_cached_repositories' or 'search_documentation' which have different purposes.

  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. There's no mention of prerequisites, when clearing is appropriate, or how this differs from related operations like refreshing or searching documentation. Users must infer usage from the name alone.

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

• get_repository_docsC
  2.9/5.0
  Behavior2/5

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

  With no annotations provided, the description carries full burden for behavioral disclosure but provides minimal information. It mentions 'documentation' but doesn't specify what format is returned (e.g., README, wiki pages, API docs), whether authentication is required, if there are rate limits, or how the 'force_refresh' parameter affects behavior. The description doesn't contradict annotations since none exist, but it fails to provide adequate behavioral context.

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

  Conciseness5/5

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

  The description is a single, clear sentence that efficiently communicates the core purpose without unnecessary words. It's appropriately sized for a simple retrieval tool and front-loads the essential information. Every word earns its place in this concise formulation.

  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?

  For a tool with 3 parameters, no annotations, and no output schema, the description is insufficiently complete. It doesn't explain what 'documentation' means in this context, what format the results take, whether authentication is needed, or how errors are handled. The presence of a 'force_refresh' parameter suggests caching behavior that should be explained but isn't addressed in the description.

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

  Parameters3/5

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

  Schema description coverage is 100%, so the schema already documents all three parameters thoroughly. The description adds no additional parameter semantics beyond what's in the schema - it doesn't explain what 'documentation' encompasses or provide examples of owner/repo values. This meets the baseline expectation when schema coverage is complete.

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

  Purpose4/5

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

  The description clearly states the action ('Get documentation') and resource ('for a specific GitHub repository'), making the purpose immediately understandable. It distinguishes from siblings like 'search_documentation' by focusing on retrieval for a specific repo rather than searching across repos. However, it doesn't explicitly differentiate from 'list_cached_repositories' which might also involve documentation access.

  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 doesn't mention when to choose this over 'search_documentation' for finding docs, or how it relates to 'list_cached_repositories' which might show cached documentation. There's no indication of prerequisites, error conditions, or typical use cases.

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

• search_documentationC
  2.9/5.0
  Behavior2/5

  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 mentions 'cached documentation', implying a read-only operation, but doesn't specify aspects like search scope (e.g., full-text, titles only), performance, rate limits, or error handling. This leaves significant gaps for a search tool.

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

  Conciseness5/5

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

  The description is a single, efficient sentence that directly states the tool's function without unnecessary words. It's front-loaded and wastes no space, making it highly concise and well-structured.

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

  Completeness2/5

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

  Given the complexity of a search operation with no annotations and no output schema, the description is incomplete. It lacks details on behavioral traits (e.g., search behavior, caching implications) and output expectations, which are crucial for effective tool use in this context.

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

  Parameters3/5

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

  The input schema has 100% description coverage, clearly documenting the three required parameters. The description adds no additional meaning beyond the schema (e.g., it doesn't explain how 'query' is processed or what 'owner' and 'repo' refer to), so it meets the baseline but doesn't enhance understanding.

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

  Purpose4/5

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

  The description clearly states the action ('Search within cached documentation') and the resource ('for a repository'), making the purpose understandable. However, it doesn't explicitly differentiate from sibling tools like 'search_repository' or 'get_repository_docs', which likely have overlapping domains, so it misses the highest 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?

  The description provides no guidance on when to use this tool versus alternatives like 'search_repository' or 'get_repository_docs'. It mentions 'cached documentation' but doesn't clarify prerequisites (e.g., if docs must be pre-cached) or exclusions, leaving usage context vague.

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

• search_repositoryC
  2.9/5.0
  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 for behavioral disclosure. While 'Search' implies a read operation, the description doesn't disclose whether this requires authentication, has rate limits, what the return format looks like, whether it searches live data or cached repositories, or any other behavioral traits. For a search tool with zero annotation coverage, this is inadequate.

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

  Conciseness5/5

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

  The description is a single, efficient sentence that communicates the core purpose without unnecessary words. It's appropriately sized for a simple search tool and front-loads the essential 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?

  For a search tool with no annotations and no output schema, the description is insufficiently complete. It doesn't explain what 'Google CodeWiki' is, what kind of results to expect, whether this searches across all GitHub or a specific subset, or how results are returned. The lack of output schema means the description should compensate by explaining return values, which it doesn't do.

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

  Parameters3/5

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

  Schema description coverage is 100%, with the single parameter 'query' already documented in the schema as 'Search query for repository name or owner/repo format'. The description doesn't add any additional semantic context about parameter usage beyond what the schema provides, so the baseline score of 3 is appropriate.

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

  Purpose4/5

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

  The description clearly states the action ('Search for') and resource ('a GitHub repository on Google CodeWiki'), providing a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'search_documentation' or 'list_cached_repositories' - it's unclear if this searches across all repositories or only cached ones, or how it differs from documentation search.

  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 about when to use this tool versus alternatives. With sibling tools like 'search_documentation', 'list_cached_repositories', and 'get_repository_docs', the description offers no context about when this repository search is appropriate versus those other search/list operations.

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

• list_cached_repositoriesB
  3.2/5.0
  Behavior2/5

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

  With no annotations provided, the description carries full burden for behavioral disclosure. It states what the tool does but reveals nothing about permissions needed, rate limits, response format, pagination, or whether the operation is idempotent. For a tool with zero annotation coverage, this is insufficient behavioral context.

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

  Conciseness5/5

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

  The description is a single, efficient sentence that communicates the core purpose without any wasted words. It's appropriately sized for a simple list operation and front-loads the essential information immediately.

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

  Completeness3/5

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

  For a zero-parameter tool with no output schema, the description provides the minimum viable information about what the tool does. However, it lacks important context about the response format, caching behavior implications, and how this differs from sibling search tools, leaving gaps in overall 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 tool has zero parameters with 100% schema description coverage, so no parameter documentation is needed. The description appropriately doesn't discuss parameters, earning a baseline score of 4 for correctly handling this parameterless scenario.

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

  Purpose4/5

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

  The description clearly states the action ('List') and target resource ('repositories currently cached'), making the purpose immediately understandable. It doesn't distinguish from sibling tools like 'get_repository_docs' or 'search_repository', but the verb+resource combination is specific enough for basic understanding.

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

  Usage Guidelines2/5

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

  The description provides no guidance on when to use this tool versus alternatives like 'search_repository' or 'get_repository_docs'. There's no mention of prerequisites, timing considerations, or comparison with sibling tools, leaving the agent to infer usage context independently.

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