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

No annotations are provided, so the description must carry the behavioral disclosure burden. It transparently states the content coverage (all questions, options and verdicts), but it does not explicitly say the operation is read-only, describe the response format, or note any size/pagination characteristics.

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 sentence with no filler, and the key content coverage is stated first before the purpose. Every word contributes meaning.

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 parameterless tool that returns the whole decision tree, the description sufficiently indicates what will be returned (questions, options, verdicts) and why it is useful. It could add the response structure or an explicit alternative, but the absence of parameters and schema makes this a near-complete description.

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 coverage is 100%, so there are no parameter semantics for the description to clarify. The baseline of 4 applies because no parameters exist to document.

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 (the Employment rights checker guide) and the full scope of the content (every question, option and verdict), distinguishing it from step-by-step sibling tools like checker_answer and checker_start. It lacks an explicit action verb such as 'retrieve' or 'return', but the intended purpose is clear.

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?

'For reasoning end to end' gives an explicit use case: call this tool when you need the complete decision tree at once rather than navigating stepwise. It does not name alternative tools or state when not to use it, but the context from the sibling list makes the usage scenario reasonably clear.

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