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

Annotations already declare a safe, idempotent read with no side effects, and the description adds the concrete payload an agent receives (fields plus the `say` summary). No auth or cost caveats, but with annotations covering the safety profile and no output schema, disclosing return contents is meaningful added 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?

Two compact sentences, front-loaded with the resource and then the fields. Slightly wasteful since the opening clause repeats the title verbatim, but otherwise tight with no filler.

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 parameterless read tool whose annotations cover safety and which has no output schema, the description is nearly complete: it lists return fields and flags the `say` summary. Missing only an explicit statement that no arguments are needed and how it differs from adjacent profile readers.

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 per the baseline this scores 4. There is nothing for the description to disambiguate beyond confirming it is a parameter-free retrieval.

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 specific resource (the person's profile, CV and saved answers) and enumerates the data it covers: name, contact details, links, CV text, titles, skills, years, standard answers and introduction openness. Clear verb+resource, though it does not explicitly distinguish itself from near-siblings like get_about_me or get_my_account.

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?

Usage is only implied: an agent can infer this reads the user's profile data, but there is no explicit when-to-use, when-not, or routing to alternatives such as get_about_me or get_my_account. The content enumeration implies scope but does not guide selection.

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