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

Annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the safety profile is covered. The description adds one genuinely useful trait beyond that: exported CSV files retain their own copy until deleted separately, which tells the agent deletion is not global. It says nothing about permissions or reversibility ('for good' only implies permanence).

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?

Three short sentences with the action and its permanence front-loaded, then the caveat. The trailing 'Free.' is a bare fragment whose meaning (no cost? free-tier feature?) is unclear and slightly weakens an otherwise tight statement.

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 tool with strong annotations and no output schema, the core is present, but the description leaves out how to locate a valid response_id and whether the deletion affects aggregate form stats or summaries. Those omissions matter for an irreversible operation.

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?

There is one required parameter, response_id, with 0% schema description coverage, and the description only implies it selects 'one response' — it does not say how to obtain the id or that it is the 32-36 character response identifier. Adequate but the schema gap is not compensated.

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 ('Delete') and a precisely scoped resource ('one response'), which separates it from bulk or form-level deletion like forms_delete. It does not explicitly name a sibling, but the scope is unambiguous.

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 two concrete triggering scenarios — a person requesting erasure and spam removal — which is real when-to-use guidance rather than generic filler. It stops short of naming an alternative (e.g. forms_list_responses to find the id) or stating when not to use it.

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