Get a Chinese inspection report

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

Annotations already declare readOnlyHint and openWorldHint, so safety is covered. The description usefully discloses report contents (accident, flood, fire, EV battery), but says nothing about source coverage, latency, or empty-result behavior.

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 front-loaded sentence with no filler. It is efficient, though extremely terse given the two-parameter surface.

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 report fetch with no output schema, describing report contents partially compensates. But missing usage guidance and unexplained 'id' semantics leave real gaps for a two-parameter tool.

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 coverage is only 50%: the 'source' enum is documented in the schema, but 'id' is bare and the description does not explain that id is the car identifier or clarify when the source hint matters. The description adds essentially no parameter meaning.

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?

States a specific resource (inspection report) scoped to 'one Chinese car' and enumerates the report contents. It distinguishes itself from get_chinese_car by the 'inspection' framing, though it never names that sibling explicitly.

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 explicit when-to-use instruction or alternative routing. Usage is only implied by the name and the 'one Chinese car' scope, leaving the agent to infer that this is the deep-check counterpart to get_chinese_car.

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