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

With no annotations provided, the description carries the full burden. It does describe what the tool exposes (full decision tree content) and its intended use (end-to-end reasoning), which gives some sense of expected behavior. It does not mention output format, size, or side effects, but for a zero-parameter content retrieval tool this is a reasonable, if minimal, disclosure.

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 tight sentence that clearly states the full scope of the tool. Every word earns its place, and the key idea—whole decision tree—is front-loaded. No redundant or filler content.

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 with no output schema, the description gives enough information for an agent to understand what it will receive and why it might be useful. It could more explicitly say 'returns all questions, options, and verdicts,' but the current wording is sufficient for correct invocation in the context of the sibling checker tools.

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, so parameter documentation is unnecessary. The baseline of 4 applies because there is no parameter burden for the description to carry. The description appropriately focuses on what the tool returns rather than inputs.

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 identifies the resource: every question, option, and verdict of the Licence entitlement checker guide. It also signals scope ('whole decision tree') and purpose ('reasoning end to end'), which distinguishes it from the interactive checker siblings. However, it lacks an explicit verb like 'retrieve' or 'get', so it stops just short of a 5.

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 viewing the complete tree rather than stepping through it interactively. But it does not explicitly state when to choose this tool over checker_start or checker_answer, nor does it mention any exclusions. Usage context is present only by implication.

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