  3.1/5.0
  Behavior2/5

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

  With no annotations provided, the description carries full burden but only states what the tool does, not how it behaves. It doesn't disclose whether this is a read-only operation, if it requires authentication, rate limits, error conditions, or what happens if the language isn't supported. The description adds minimal behavioral context beyond the basic function.

  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 wasted words. It's appropriately sized for a simple tool and front-loads the core functionality without unnecessary elaboration.

  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 has an output schema (which handles return values), no annotations, and simple parameters, the description covers the basic purpose adequately. However, for a tool with 0% schema description coverage and no annotations, it should provide more parameter guidance and behavioral context to be truly complete.

  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 schema description coverage is 0%, so the description must compensate. It mentions 'for the specified language' which maps to the single 'language' parameter, providing some semantic meaning. However, it doesn't specify format constraints, valid values, or examples for the language parameter, leaving significant gaps.

  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') and resource ('application best practices') with specific format ('Markdown format') and scoping ('for the specified language'). It doesn't explicitly differentiate from sibling tools like get_style_guide or list_templates, but the purpose is unambiguous.

  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 get_style_guide or list_templates. It mentions the language parameter but doesn't explain prerequisites, limitations, or appropriate contexts for usage.

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

  3.2/5.0
  Behavior2/5

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

  No annotations are provided, so the description carries the full burden. It mentions the output format ('Markdown format') but doesn't disclose behavioral traits such as whether this is a read-only operation, potential rate limits, authentication needs, or error handling. For a tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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

  Conciseness5/5

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

  The description is a single, efficient sentence that front-loads key information (action, resource, format, scope) with zero waste. Every word earns its place, making it appropriately sized for the tool's simplicity.

  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 low complexity (one parameter) and the presence of an output schema, the description is reasonably complete. It covers the purpose and output format, though it lacks behavioral details and usage guidance. With annotations absent, it could do more, but the output schema mitigates some gaps.

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

  Parameters3/5

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

  Schema description coverage is 0%, with one parameter ('language') undocumented in the schema. The description adds minimal semantics by implying the parameter specifies the language for guidelines, but it doesn't clarify allowed values, examples, or constraints. Baseline is 3 due to low coverage, but the description only partially compensates.

  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') and resource ('coding style guidelines'), specifying the format ('Markdown format') and scope ('for the specified language'). It distinguishes from sibling tools like 'get_best_practices' by focusing on style guidelines rather than broader practices, though it doesn't explicitly contrast them.

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

  Usage Guidelines2/5

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

  No guidance is provided on when to use this tool versus alternatives like 'get_best_practices' or 'list_templates'. The description implies usage for language-specific style guidelines but lacks explicit context, prerequisites, or exclusions, leaving the agent to infer appropriate scenarios.

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

• list_templatesB
  3.3/5.0
  Behavior2/5

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

  No annotations are provided, so the description carries the full burden. It states the tool lists templates grouped by type and language, which is basic behavioral info, but lacks details on permissions, rate limits, pagination, or response format. For a tool with no annotations, this is a significant gap in transparency about how it behaves beyond the core action.

  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 clearly states the purpose without any wasted words. It's front-loaded with the core action and includes essential details (grouping by type and language). Every part of the sentence earns its place, 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.

  Completeness4/5

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

  Given the tool's low complexity (0 parameters, no annotations, but has an output schema), the description is reasonably complete. It specifies what is listed and how it's grouped. With an output schema present, the description doesn't need to explain return values, so it covers the basics adequately, though it could benefit from more behavioral context.

  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 0 parameters with 100% schema description coverage, so the schema fully documents the lack of inputs. The description adds no parameter info, which is appropriate here. Baseline for 0 parameters is 4, as it doesn't need to compensate for any gaps, and the description doesn't mislead about inputs.

  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 verb ('List') and resource ('templates'), specifying grouping by type and language. It distinguishes from siblings like 'get_best_practices' and 'get_style_guide' by focusing on templates rather than other content types. However, it doesn't explicitly mention what distinguishes it from potential template-related siblings (none listed here), so it's not a perfect 5.

  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 prerequisites, context for use, or compare to sibling tools like 'get_best_practices' or 'get_style_guide'. Usage is implied by the action of listing templates, but no explicit when/when-not instructions are given.

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