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 idempotency profile is fully covered structurally. The description adds no further behavioral context such as permission requirements or what happens for a non-existent/inaccessible ID, so it earns only baseline credit.

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 efficient sentence with the resource and the selector front-loaded and no filler. It is appropriately sized for a one-parameter lookup tool, though it is too terse to be exemplary.

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 read-only getter with full annotation coverage and a single well-documented parameter, the description is broadly sufficient. It is slightly thin in that there is no output schema and 'detailed information' leaves the returned shape unspecified, but nothing critical to invocation is 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 parameter with 100% schema description coverage, including format and UUID pattern, so the schema fully documents it. The description only restates 'by its ID' and adds no semantics beyond what the schema already conveys, which is the baseline case.

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 gives a specific verb (Get) and resource (form response) and scopes it to a single record identified by ID, which separates it from list_form_responses. It does not, however, name or contrast itself with the closely named sibling get_form_response_answer (which retrieves answers rather than the response record 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?

Use case is implied: fetch one response when you already have its ID. There is no explicit statement of when to prefer this over list_form_responses or get_form_response_answer, and no prerequisites or exclusions are given.

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