get_user

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

No annotations are provided, so the description carries the full burden. It does add useful operational context — the exact endpoint and the required Authorization: Bearer PERSONAL_OAUTH_TOKEN header — but says nothing about rate limits, response shape, or what happens if the token is missing or expired.

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?

Short and front-loaded, with labeled sections that make the endpoint and auth requirements scannable. The opening line and 'Returns current user details' are largely redundant restatements, a minor waste.

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 no-param read tool with no output schema and no annotations, the description supplies endpoint and auth, which is the most important missing piece. It still omits what fields the user object contains and how it differs from get_current_user, leaving the agent under-informed for selection.

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 tool takes zero parameters, so there is nothing for the description to disambiguate and the schema is trivially complete. Baseline for a no-parameter tool.

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?

States a clear verb and resource ('Get authenticated user information') and pins the exact endpoint GET /users/me/. However, it does nothing to separate itself from the sibling get_current_user, which appears to cover the same 'who am I' resource — the agent gets no basis for choosing between them.

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 statement of when to use this tool, when not to, or which sibling to prefer. Given that get_current_user is a near-identical sibling, the absence of routing guidance is a real gap rather than a stylistic one.

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