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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety behavior is fully covered structurally. The description adds value only by enumerating the returned fields (type, project, date, result, agency, inspector, notes), which partially compensates for the absence of an output schema, but nothing is said about missing-record behavior or response shape.

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 no filler, and the key qualifier ('One inspection') is front-loaded. It is terse to the point of being a fragment, but nothing is wasted.

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 trivial single-record read with full annotation coverage and a 100%-documented parameter, the listing of returned fields is the main useful addition since there is no output schema. However, an agent still cannot tell from the description how the call behaves for a non-existent ID or whether related records are expanded.

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, and the schema already explains where to obtain inspection_id. The description adds no additional meaning about the identifier format or constraints, 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?

The phrase "One inspection" implies retrieval of a single record, which distinguishes it from list_inspections, but there is no verb and no explicit statement that this fetches an inspection by ID. The remaining text is a field inventory rather than a statement of purpose.

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?

The description offers no guidance on when to use this tool versus list_inspections or any other sibling, and no prerequisites or error conditions are mentioned. The only routing hint ('inspection_id from list_inspections') lives in the schema, not the description.

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