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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety and determinism profile is fully covered by structured data. The description adds only that retrieval is by ID, which is already implied by the single required parameter; it discloses nothing about errors on missing IDs or result scope.

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 short sentence with the key information front-loaded and no padding. It is efficient, though it is so terse that it omits potentially useful context rather than being wasteful.

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 read tool whose annotations cover the safety profile, the definition is close to sufficient, but with no output schema and only 'detailed information' as a return-value hint, the agent gets no sense of what fields an answer contains or how it relates to its parent response.

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% and there is only one parameter ('id', uuid), so the schema fully documents the input. The description restates the ID lookup without adding format, constraint, or scoping semantics beyond what the schema provides.

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?

The description states a specific verb and resource ('Get ... a specific form response answer by its ID'), which is unambiguous. However, it does not distinguish this tool from siblings like get_form_response (the parent response) or list_form_response_answers, so an agent must infer the boundary itself.

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 guidance on when to use this tool versus get_form_response or list_form_response_answers, nor any prerequisite or context. The only hint is the implicit 'by its ID', which the agent must extrapolate.

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