api_search_category

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 only mentions 'browse/search' but does not state that the tool is read-only, any required permissions, or the nature of the results (e.g., returns a list of API names, pagination details). The behavioral traits are insufficiently described.

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

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

The description is extremely concise at two sentences, front-loading the core purpose and providing a clarifying example. Every word is necessary and no extraneous content exists.

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 the presence of sibling tools and the lack of an output schema, the description is adequate but not complete. It fails to hint at the return format (e.g., list of API names) or assure read-only behavior. With only two parameters, it covers the basics but leaves gaps in expected output.

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

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

Schema description coverage is 100%, so the baseline is 3. The description adds no extra meaning beyond the schema; it only restates that categories are hierarchical. No parameter details are elaborated upon.

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

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

The description clearly states the purpose: 'Browse/search Windows APIs by category.' The example of hierarchical categories (e.g., 'Data Access and Storage/Local File Systems/File Management') adds specificity and distinguishes this tool from siblings like api_lookup (which likely searches by API name). The verb-resource pair is explicit and unambiguous.

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

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

The description implies usage when searching by category, but it does not provide explicit guidance on when to use this tool versus alternatives (e.g., api_lookup for name-based lookup) or when not to use it. No context about prerequisites or limitations is given.

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