collection_groups_v1_patch

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

With no annotations, the description must disclose behavioral traits. It mentions OAuth token requirements and references a guide resource, but it does not explain the side effects of a PATCH operation, whether it partially updates or replaces, what data it returns, or any error handling. The pointer to itad://guide/calling shifts responsibility and does not satisfy transparency for a mutation tool.

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 concise, using a single line with essential elements: endpoint, purpose, required body, OAuth requirement, and a guide reference. It is front-loaded and avoids unnecessary verbiage, though the guide reference could be seen as a detour.

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 PATCH tool with no annotations, no output schema, and shallow parameter descriptions, the description is insufficient. It does not explain return values, body structure, or the meaning of 'Categories.' The reference to an external guide is not a substitute for self-contained context.

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 description coverage is 100%, but the parameter descriptions are generic (e.g., '请求体（此接口必填）'). The description only repeats that body is required and mentions OAuth token fallback, which is already in the schema. It does not add meaning about the body's structure or expected fields for updating categories.

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 HTTP method and purpose: '[PATCH] /collection/groups/v1 - Update Categories.' This provides a specific verb (Update) and resource (Categories), distinguishing it from sibling operations like POST or DELETE on the same endpoint. However, the meaning of 'Categories' is not elaborated, leaving some ambiguity about what exactly is being updated.

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 gives prerequisites (required body, OAuth token) but provides no guidance on when to use this tool versus alternatives. It does not mention any exclusions or scenarios where another sibling tool (e.g., collection_groups_v1_post or collection_groups_v1_put) would be more appropriate.

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