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

Annotations already declare readOnly, idempotent, non-destructive and openWorld, so the safety profile is covered. The description adds that these are 'Proposed and booked' interviews and that a summary lands in a `say` field, which is modest extra context, but it doesn't clarify return shape or pagination since no output schema exists.

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?

It is short and front-loads the resource, but the fragments 'Proposed and booked, with the candidate' and the bare `say` reference are telegraphic rather than efficient, leaving the agent to guess at meaning.

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 simple zero-param read tool with full annotation coverage, the description is nearly adequate, but the opaque `say` reference and lack of any output-shape hint leave a meaningful gap given no output schema is provided.

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, which is the baseline-4 case. There is nothing for the description to disambiguate at the parameter level.

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 title/first fragment 'The employer's interviews' identifies the resource and implicitly the employer-side scope, which loosely distinguishes it from the sibling list_interviews (candidate-side). However there is no verb ('list') and no statement of what the tool does, so the purpose is only vaguely conveyed.

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 when-to-use guidance and no mention of the closely-related sibling list_interviews or get_hiring_overview. The agent must infer the employer-vs-candidate distinction entirely on its own.

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