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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only states that the tool is the first question; it does not disclose whether invoking it initializes or resets state, whether it has side effects, or what the returned question looks like.

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 sentence that is immediately clear and contains no filler. It front-loads the core purpose in minimal space.

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 no-parameter start tool this is near-adequate, but because there is no output schema and no annotations, an agent still lacks details on the return format and the expected next step after the first question. The sibling names hint at a flow, but the description itself does not complete the picture.

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 tool has zero parameters and the schema is fully covered, so the description does not need to add parameter meaning. This meets the zero-parameter 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 identifies the tool as the first question of the Towing capacity checker decision guide, making its role as the entry point clear. It does not explicitly differentiate it from siblings like checker_answer or checker_tree, but 'first question' conveys enough to avoid confusion.

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?

Use at the start of the checker is implied by 'first question,' but there is no explicit guidance about when to choose this tool over checker_answer or checker_tree, nor any mention of prerequisites or exclusions. The usage context is implied rather than stated.

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