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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered; the description adds two pieces of information not in structured data: an API-key authentication requirement and the round-open precondition. It still omits what happens to the response after withdrawal (deleted vs. marked withdrawn) and whether it can be re-submitted.

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 short sentences, the action stated first and the constraint second, with no filler. It is tight but arguably too terse for a destructive operation.

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, non-idempotent mutation with no output schema and an undocumented parameter, the description covers the bare minimum (auth + precondition). It leaves open the reversibility, the post-withdrawal state of the listing, and where to obtain listing_id.

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% and the single parameter listing_id is not annotated anywhere. The name is fairly self-explanatory, but the description adds no format, source, or retrieval guidance (e.g., from my_responses or get_listing), so it does not fully compensate for the schema gap.

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 ('withdraw your response') and adds a temporal scope ('while the round is open'). It is clearly the inverse of the sibling 'respond' / 'my_responses', though it does not name them explicitly.

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?

Gives one precondition for use ('while the round is open'), which is real guidance, but says nothing about what to do if the round is closed, whether a response can be withdrawn more than once, or which sibling to use instead.

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