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

Annotations already flag destructiveHint=true and openWorldHint=true, but the description adds the crucial specifics behind that flag: the reply is publicly visible, and an empty reply deletes the existing one. That is real added context beyond the structured hints, though it says nothing about permissions or whether the review must exist first.

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?

Three compact clauses, front-loaded with the publish/replace action, then visibility, then the deletion rule, then the safety caution. No filler and no redundancy.

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 destructive mutation with no output schema, the description covers the action, its public consequence, the removal behavior, and a confirmation nudge — enough to call it correctly. It would be a 5 with an explicit tie-break against reply_to_review.

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 all four parameters are already documented, including the empty-string removal semantics and the idempotency contract. The description repeats the empty-reply behavior rather than adding anything new, so the baseline of 3 is 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?

States a specific verb+resource: publishes or replaces the business reply to an appointment review, and notes it appears under the review on the public booking page. This distinguishes it from list_booking_reviews and set_booking_review_hidden, but it never disambiguates from the near-identically named sibling reply_to_review, which is the most likely confusion.

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 a useful caveat for public-facing output ("confirm the wording with the user first"), which is genuine when-to-use guidance. However, there is no explicit statement of when to choose this over reply_to_review or the other booking-review tools, so an agent must infer the boundary from the name alone.

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