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

With no annotations provided, the description must carry the behavioral transparency burden. It does convey that the tool exposes the complete set of questions, options, and verdicts, which implies a read-oriented, full-content response. It does not mention output format, potential size, or whether this is a static representation versus an interactive guide.

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, efficiently worded sentence. It front-loads the content scope and immediately adds the end-to-end reasoning purpose. Every phrase earns its place with no redundancy or filler.

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 zero-parameter tool with no output schema, the description reasonably covers what the tool is and what it returns. It could be more complete by noting how the tree should be used alongside checker_answer and checker_start, or by describing the response format, but it is sufficient for basic selection and invocation.

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 are zero parameters, so the schema coverage is effectively complete. The description correctly focuses on the returned content rather than parameter details, which are unnecessary here. The baseline for no-parameter tools 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 description clearly states what content the tool provides: every question, option, and verdict of the Towing capacity checker guide. This identifies a specific resource and distinguishes it as the whole tree, though it lacks an explicit verb like 'return' or 'retrieve' and does not name sibling tools.

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 phrase 'for reasoning end to end' implies when this tool should be used: when the agent needs the full decision structure rather than a single step. However, it does not explicitly exclude alternatives like checker_answer or checker_start, nor explain how the tree relates to them.

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