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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds useful behavioral context by enumerating the tool's expected outputs: verdict, present and missing parts, rewrite in the rep's voice, and one coaching line. It does not explain what a 'verdict' is, but it goes beyond the annotations meaningfully.

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?

One tight sentence with a colon-separated list of outputs. It is front-loaded, scannable, and contains no filler or repetition.

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 single-string input with no output schema, the description covers both the input and the output dimensions. However, it leaves the meaning of 'verdict' vague and provides no context about when to invoke this tool relative to similar siblings, so an agent still has some ambiguity.

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 0%, so the description must carry parameter meaning. It clarifies that the 'ask' input is the salesperson's statement when offering an appointment, which adds meaning beyond the bare string type. However, it does not specify expected format, length, or whether verbatim text is required.

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 uses the specific verb 'Reviews' and names the resource ('what a salesperson said when offering an appointment'), then lists concrete outputs: verdict, present/missing parts, rewrite, and coaching line. It is clear, but it does not explicitly distinguish this tool from the sibling check_appointment_ask, which likely overlaps.

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 guidance on when to use review_appointment_ask versus check_appointment_ask or rewrite_follow_up_text. The description only states what the tool does, with no conditions, exclusions, or alternatives to help an agent select among siblings.

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