get_subcategory

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only says 'Get details', which implies a read-only operation but does not explicitly state side effects, error handling, or what 'details' includes. The output schema exists but the description adds no behavioral context beyond the tool's name.

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 a single short sentence with no unnecessary words, which is appropriately concise and front-loaded. It could be slightly more informative without becoming verbose, but as written it is efficient.

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?

For a simple get-by-ID tool with one required parameter and an output schema, the description is minimally sufficient. It does not mention error conditions or any usage prerequisites, but the tool's simplicity partially compensates. However, additional context about what details are returned or how the ID should be formatted would make it more complete.

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?

The schema has 0% description coverage for the single parameter, and the description does not compensate. It never mentions 'subcategory_id' or explains what it should be. The parameter name itself is reasonably self-explanatory, but the description adds zero value over the schema, failing to offset the lack of schema descriptions.

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 states a specific action ('get') on a specific resource ('details for a specific subcategory'), which is clear and distinct from sibling tools like list_subcategories (which lists all) or get_category (which fetches a category). It doesn't explicitly differentiate from these alternatives, but the resource name makes the purpose 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?

There is no guidance on when to use this tool versus alternatives. The description only says 'get details' with no mention of prerequisites, when not to use it, or any context that would help an agent choose between this and list_subcategories or get_category. The agent is left to infer that this is for a single known subcategory ID.

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