pm_get_user_label

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

No annotations are provided, and the description only states the HTTP method. It discloses no behavioral traits such as idempotency, authentication requirements, or what the response contains. The description fails to add any behavioral context.

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 short (7 words) but at the cost of clarity and informativeness. It is under-specified rather than concise, offering no structure or front-loaded key information.

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?

Despite having an output schema, the description fails to explain the tool's purpose or behavior. It is completely inadequate for an agent to understand what the tool does or when to invoke it.

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?

With 0% schema description coverage, the description must explain the parameters but does not. It provides no meaning for 'label_id' or 'x_user_id', leaving the schema's bare structure unexplained.

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 'GET /user-labels/{label_id}.' merely restates the HTTP method and path, not clearly stating that the tool retrieves a user label by ID. It is a tautology of the tool's name and provides no meaningful purpose beyond the endpoint.

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 no guidance on when to use this tool versus sibling tools like pm_get_tag or pm_list_user_labels. It lacks any context for selection or exclusion.

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