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

Annotations flag destructiveHint=true, but the description materially changes how an agent should act on that by disclosing the effect is deferred and gated on human approval, and that an approval link is returned. It does not cover retry/idempotency behavior (idempotentHint=false) or whether the pending request expires, which would have completed the picture.

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 sentences, zero filler, with the approval-gating constraint front-loaded right after the action statement. Nothing to trim.

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 one-parameter tool with no output schema, the description conveys the essential mechanics: what it does, that it returns a link, and that no state changes yet. The remaining gap is the handoff — where review_id comes from and that get_request_status is how the approval outcome is observed.

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% for the single parameter, and the description says nothing about review_id — not its expected UUID format, not that it comes from list_reviews, not whether it identifies a reply or its parent review. The one parameter an agent must supply is left entirely to the bare schema.

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-and-resource pair: request approval to delete the business's reply to a Google review. This is clearly separable from request_review_reply (drafting/publishing) and request_delete_post, and it names the exact artifact being deleted.

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?

'Ask the user to approve deleting...' plus 'nothing changes until approved' establishes the approval-flow context in which this tool belongs. It stops short of routing explicitly to siblings like request_review_reply (to modify instead) or get_request_status (to check the outcome), so an agent must infer those.

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