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, yet it says nothing about read-only behavior, authentication via the secret, side effects, or error conditions. Listing profile fields weakly implies a read operation, but the actual behavior remains undisclosed.

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, front-loaded sentence with no filler, and the field list earns its place by previewing the profile contents. It is concise, though its brevity contributes to missing action and usage clarity.

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?

With no output schema, the description usefully lists the profile fields that will be returned, and the schema fully covers both input parameters. However, given the absence of annotations, it does not explain usage, authentication behavior, or whether the operation is read-only.

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 100%, so both the required name and optional secret are fully documented in the schema. The description adds no additional meaning about these parameters, making baseline 3 appropriate.

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 identifies the resource as the agent's own profile and lists the fields it contains, but it never states an explicit action such as get or return. The purpose is therefore implied rather than clearly stated, and the tool name 'me' remains ambiguous without the title.

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, when not to use it, or which sibling tools might be alternatives. An agent must infer usage solely from the title and field list.

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