List Users By Id Favorites

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. 'Get' implies a read-only operation, which is useful, but the description does not disclose whether authentication or special permissions are required, how results are ordered, or whether pagination exists. The output schema covers return structure, but other behavioral details are absent.

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 clear sentence with no wasted words. It front-loads the core action and resource, making it easy to scan. However, the extreme brevity leaves out context that would be valuable, so it is efficient but not fully informative.

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 description is minimally complete given the output schema, but the absence of annotations and the 0% schema coverage leave important gaps. An agent is not told whether the ID is a user ID, whether this is different from the current user's favorites, or what role 'accept-language' plays. A few additional words about scope and usage would make a meaningful difference.

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 0%, so the description needed to explain the parameters. It implies the 'id' parameter identifies a user, but it does not explicitly state that, nor does it mention the optional 'accept-language' parameter or how it affects the response. The description adds minimal meaning beyond the schema field names.

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 identifies the resource ('user's favorited recipes') and a read verb ('Get'). The tool's name and required 'id' parameter further clarify that this is a per-user favorites list, though the description itself doesn't explicitly distinguish it from related favorites endpoints.

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. Sibling tools like 'list_users_self_favorites' and 'list_users_by_id_ratings' exist, but the description does not explain that this endpoint is for a specific user by ID rather than the current user, nor does it mention any conditions for choosing it.

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