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

Annotations already declare destructiveHint=true, readOnlyHint=false, and idempotentHint=false. The description's 'Permanently... There is no undo' reinforces the destructive profile but adds little that the flags don't already convey, and says nothing about auth needs or effects on related data.

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, with the destructive nature front-loaded in the first clause. Nothing is wasted and the critical warning comes first.

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 simple two-parameter destructive operation, the description plus annotations plus a fully documented schema cover what an agent needs. The only shortfall is no explicit tie-breaker against the plural delete_responses sibling.

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% with only two required params, and the schema explains provenance for each (list_projects/create_project, list_responses). The description adds no parameter meaning, so the baseline of 3 applies.

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 ('delete one response') with the word 'Permanently' signaling irreversibility. It does not explicitly distinguish itself from the sibling delete_responses, though 'one response' hints at singular vs bulk scope.

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?

No guidance on when to choose this over delete_responses (the bulk sibling) or get_response/update alternatives. The only routing signal is the implicit singular 'one response', which is left for the agent to infer.

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