List fleet vehicles

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

The description explicitly states READ-ONLY, required scope basics:read, and zero-indexed pagination, adding significant behavioral context beyond the annotations which only hint at read-only and destructive intent.

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 two sentences long, front-loads the purpose, and includes essential context like pagination and scope without any wasted 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 read-only list tool with 2 optional parameters and no output schema, the description covers purpose, optional filter, pagination, required scope, and read-only nature. No important information 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?

The input schema already has high coverage (100%) with descriptions for both parameters. The description adds no new parameter-specific information beyond what's in the schema, so it meets but does not exceed the baseline.

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 tool lists fleet vehicles, with an optional filter by person. This differentiates it from sibling tools like list_people or list_assets.

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 implies usage for retrieving fleet vehicles and mentions optional person filtering, but does not provide explicit guidance on when to use this tool over alternatives or when not to use it.

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