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

Annotations already declare destructiveHint=true, idempotentHint=false and openWorldHint=false, so the safety profile is known. The description adds real value with the lifecycle/actor constraints, but it doesn't say what withdrawing does to the record (deleted vs. cancelled), whether it is reversible, or what happens on a rejected withdrawal.

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?

A single front-loaded sentence with no filler; the actor restriction is placed where it is most useful, at the end as a scoping qualifier.

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 destructive mutation with no output schema, the description supplies the two things an agent most needs: who may call it and under which state conditions. Missing is post-condition behavior (what state the entity ends in) and error semantics when the precondition fails.

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 coverage is 100% and the single parameter is fully documented as a UUID. The description adds only a small semantic nuance — the same ID may refer to either a quote request or an open intent — which is useful but not beyond baseline.

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?

Uses a specific verb ('Withdraw') against two named resource states (a quote request before quoting, an open intent during its bid window), and the '(buyer-only)' qualifier separates it from seller-side siblings like services_reject_quote and services_submit_quote.

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?

The preconditions are explicit and actionable: only before the seller has quoted, or while an intent's bid window is still running, and only for buyers. It stops short of naming the adjacent alternative tools (e.g. services_reject_quote, purchase_cancel_intent) or stating what to do if the window has closed, so it is strong but not exhaustive.

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