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

No annotations are provided, so the description must disclose behavioral traits. It does mention OAuth token requirements and the location of a guide, but it does not describe side effects, idempotency, error responses, or the created resource's representation. For a state-changing POST, this is insufficient.

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 brief—three short sentences—and front-loads the endpoint and purpose. It includes necessary auth details and a reference to a guide. No redundant words, though the guide reference could be considered extraneous.

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?

The tool has a required `body` parameter with no type or structure in either the schema or description, and no output schema. The description directs users to an external guide for full instructions, which is helpful but shifts the burden away from the tool definition. As a result, the description is not self-sufficient for an agent to invoke the tool correctly.

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 descriptions cover all parameters (100%), but the critical `body` parameter has no structure beyond 'request body (required)'. The description reinforces that body is mandatory and clarifies that OAuth can be supplied via the `oauthToken` parameter or environment variables, which adds meaning beyond the schema's 'optional' label. However, it does not describe how to construct the body.

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 opens with the HTTP method and endpoint, then the verb-object phrase 'Create new Category'. This clearly identifies the tool's function and distinguishes it from sibling tools like collection_groups_v1_get (read) and collection_groups_v1_delete.

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 states the tool creates a category, but provides no explicit guidance on when to choose it over alternatives (e.g., PATCH for updates). The only contextual clue is the endpoint name, which implies the operation. There is no when-not-to-use guidance or mention of alternative tools.

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