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

With no annotations, the description carries the behavioral disclosure burden. It accurately conveys that the tool exposes the entire guide structure rather than a single step, but it does not describe output format, size, or whether any stateful interaction is involved. This is acceptable for a simple read-only data dump but not richly transparent.

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 well-structured sentence that front-loads the key content ('Every question, option and verdict') and ends with the intended use case. No filler or redundant restatement of the title is present.

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 static-tree tool with no output schema, the description sufficiently communicates the content and intent. It could be slightly stronger by clarifying that it is a pure lookup with no dependencies, but nothing essential is missing for an agent to understand what it will receive.

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 has zero parameters, so there is nothing to document. The description adds value by explaining what the returned whole-tree content covers, matching the baseline of 4 for parameterless tools.

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 that the tool provides every question, option, and verdict in the Employer change checker guide, positioning it as a complete decision tree. It implicitly distinguishes itself from interactive siblings like checker_start and checker_answer, though it lacks an explicit verb such as 'returns' or 'lists'.

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 the tool is for obtaining the full decision tree in one call. However, it does not explicitly say when to choose this over checker_start, checker_answer, or the enquiry tools, nor does it mention exclusions.

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