pm_get_user

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

With no annotations, the description must describe behavior. It only states the HTTP method and endpoint, omitting details like error handling, authentication requirements, or what happens if the user does not exist.

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 terse but lacks essential details. Conciseness is not achieved at the expense of informativeness; the description is under-specified.

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 does not explain the return structure or behavior. It fails to provide enough context for an agent to use the tool confidently.

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 must compensate. It mentions {user_id} in the endpoint but provides no explanation of the parameters, especially x_user_id, beyond what the schema already shows.

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 specifies the HTTP method 'GET' and the resource pattern '/users/{user_id}', clearly indicating it fetches a single user by ID. This distinguishes it from sibling tools like pm_list_users and pm_get_user_label.

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?

No usage context is provided. The description does not indicate when to use this tool versus alternatives like pm_list_users for fetching multiple users or pm_get_user for fetching by other criteria.

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