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

With no annotations, the description must carry the behavioral burden. It conveys that the result is the first question but does not disclose whether calling it resets progress, whether it is purely read-only, or what happens if it is called again after starting. These are material gaps for a decision guide tool.

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 with no filler, and the key phrase 'first question' is front-loaded. It is appropriately short for a zero-parameter tool, though it could have added one usage sentence without becoming bloated.

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 start tool, identifying the returned resource as the first question is minimally adequate, but the lack of an explicit verb, return format, and relationship to checker_answer leaves the agent to infer next steps. No output schema exists to compensate.

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 already describes an empty object, so there is nothing for the description to add. Baseline 4 applies because parameter semantics cannot be improved further.

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 resource as the first question of the Waste carrier, broker and dealer checker decision guide, but it is a noun phrase rather than an explicit action such as 'starts the guide' or 'returns the first question'. It is distinguishable from checker_answer and checker_tree only by the word 'first', which is weak differentiation.

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 guidance is given on when to call this tool versus checker_answer, checker_tree, or the enquiry tools. The word 'first' implies it is the entry point, but the description does not state that subsequent answers should be sent to checker_answer or that it should not be used mid-guide.

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