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

Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety profile is covered. The description adds genuine value beyond that by naming the interview states returned (booked, invited, proposed with offered times) and pointing to the human-readable summary in the `say` field, which the annotations do not provide. It stops short of describing ordering, pagination, or scope limits.

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 short and front-loaded, but its opening sentence is a verbatim restatement of the title and consumes space without adding information. The second sentence carries the useful content, and the parenthetical on offered times could have been folded in more tightly.

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 zero parameters, no output schema, and annotations already covering the read-only safety profile, the description is only partially obligated to explain return values. However, it names only one output field (`say`) and leaves the rest of the response shape, ordering, and scope unstated, so it is adequate but not complete.

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 no parameters, so the schema has nothing to document and the baseline is a 4. The description correctly does not waste space on nonexistent inputs.

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 first sentence, "The person's interviews," simply restates the name and title rather than stating a verb+resource like "list." The enumeration of statuses (booked, invited, proposed) does add real meaning and hints at the job-seeker side versus the sibling list_hiring_interviews, which is enough to place the tool without reading its schema, but the core purpose is only implied.

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 versus alternatives such as list_hiring_interviews, answer_interview, or schedule_interview. The reader must infer from the name alone that this is the read side of interview management.

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