profile

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

No annotations are provided, so the description carries the full behavioral burden. It does not state whether this is a read-only, authenticated, or self-only operation, what 'full' includes, or whether any privacy scoping applies.

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?

A single short, front-loaded sentence with no filler. However, the extreme brevity leaves ambiguity (whose profile) rather than resolving it, so it is efficient but under-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?

There is no output schema and no annotations, so the description must explain what the tool returns and for whom. Given the zero-param signature and the adjacent 'me' tool, the near-total absence of detail leaves the agent unable to call it 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?

The tool takes zero parameters, so there is no schema surface for the description to document. The baseline for a parameterless tool is 4; the description introduces no param confusion.

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+resource ('Show ... profile'), but 'a user's' is ambiguous when the tool takes zero parameters to identify which user. It also does not distinguish itself from the sibling 'me', which likely returns the caller's own profile.

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 when-to-use guidance is given. With a sibling named 'me' and no parameters, the agent cannot infer whether 'profile' is for the current user or another user, nor when to prefer it over 'me'.

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