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

The description adds context the annotations do not carry: the operation costs Rank Tracker credits at the current scan price, is only charged after approval, and returns an approval link. This reconciles well with destructiveHint=true and non-idempotent (a billable, user-gated action), and no contradiction exists. Only missing piece is what happens if approval is declined or stale.

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 sentence plus a clarifying parenthetical; the action and the human-approval requirement are front-loaded, and every clause (cost, exclusion, return value) carries information an agent needs.

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 annotations covering the safety profile and no output schema, the description supplies exactly the missing pieces: cost model, approval gating, and return value. Only the profile_id semantics is left implicit, which is minor for a one-parameter tool.

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 single parameter profile_id has 0% schema description coverage, and the description never mentions it or says which business profile the scan applies to. The field name is largely self-explanatory (a UUID for a profile, with list_business_profiles available), so the gap is tolerable but unaddressed.

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: request user approval for a Citation Management scan of the business's directory listings. The parenthetical exclusion ('does not create or submit listings') sharpens the scope, though it doesn't explicitly name the sibling list_citation_scans or the other request_* tools it precedes.

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' makes the human-in-the-loop precondition explicit, and the credit-charge note tells the agent this is a billable step to be used deliberately rather than speculatively. No explicit when-not-to-use condition or named alternative is given, so it falls just short of a 5.

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