get_vehicle

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

No annotations are provided, so the description must carry the full burden. While 'Get' implies a read-only operation, the description lacks details about error behavior (e.g., invalid ID), authentication requirements, or what specific 'detailed information' is returned.

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 description is a single, efficient sentence with no filler. It immediately communicates the core purpose and required parameter without unnecessary words.

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 retrieval tool with one parameter and no output schema, the description is minimally adequate. However, given the lack of annotations and output schema, it should ideally mention error cases (e.g., vehicle not found) or the nature of the returned details.

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?

With 100% schema coverage, the input parameter 'id' is already well-documented as 'The vehicle ID'. The description mentions 'by its ID' which aligns with the parameter usage but doesn't add significant semantic value beyond what the schema already provides, warranting the baseline score.

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 clearly states the operation (Get), resource (vehicle), scope (single), and retrieval method (by ID). The phrase 'single vehicle' effectively distinguishes this from the sibling 'list_vehicles' tool, though it doesn't explicitly name that alternative.

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?

While 'by its ID' implies you need a specific identifier, there is no explicit guidance on when to use this versus 'list_vehicles' for searching, or what to do if the ID is unknown. No prerequisites or error conditions are mentioned.

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