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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is fully covered. The description adds that it returns 'detailed information' for a single answer, but says nothing about permissions, missing-ID behavior, or completeness of the payload.

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 short, front-loaded sentence with no filler. It is efficient, though the phrasing is generic enough that it could be tightened or enriched without growing.

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 single-ID read with complete schema coverage and annotations covering safety, no output schema is required to describe returns. The definition is essentially sufficient; only cross-references to the list/parent siblings are missing.

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 a single required parameter with 100% schema description coverage ('Form response answer ID' with a UUID pattern), so the schema fully carries parameter meaning. The description's 'by its ID' merely echoes the schema, so the baseline 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?

Names a specific verb (get) and resource (a specific form response answer) scoped by ID, which cleanly separates it from the plural sibling list_form_response_answers and from the parent get_form_response. It does not explicitly name those siblings, so it falls short of a 5.

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?

There is no statement of when to use this rather than list_form_response_answers (to enumerate answers for a response) or get_form_response (to fetch the parent response). Usage is only implied by the get-by-ID naming convention, which is weak given the very large get/list/delete sibling set.

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