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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds nothing beyond the annotation set: no note on what the response contains, whether the test id is a UUID, or what happens when the id is unknown (404 vs empty).

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?

The one informative sentence is duplicated verbatim, and the remaining sentence is boilerplate about describe_operation. There is no front-loaded explanation of purpose or return value, so length is wasted rather than earned.

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?

This is a nested-object, zero-coverage, no-output-schema tool, which puts the full explanatory burden on the description. The description covers none of it: not the id semantics, not the query bag, not the return shape or error behavior.

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 0% and both parameters (a nested params.id object and a free-form query object) are undocumented in the schema. The description supplies no clarification at all about the id format, length limits, or what the query object accepts, leaving the agent to guess.

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 repeats the title verbatim: "GET /api/impairment/tests/:id. GET /api/impairment/tests/:id." It conveys the resource path but is a tautological restatement of the name, not an explanation of what the tool returns or how it differs from the sibling list tool get_impairment_tests_2f78a233dea7ff5599ec9f1c.

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 when-to-use or when-not-to-use guidance is given. The only routing signal is the boilerplate pointer to describe_operation for native request schemas, which implies a workflow but never says when this tool rather than the impairment tests list tool should be called.

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