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

With no annotations provided, the description carries the full burden of behavioral disclosure. It does disclose content coverage and that the tool represents the whole guide tree, but it does not describe return format, traversal mechanics, or any side effects. There is no contradiction, but the behavioral detail is thinner than it could be.

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, compact sentence with no filler. The key information—complete coverage of questions, options, and verdicts—is front-loaded, and every phrase contributes meaning beyond the title.

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 and no annotations, the description gives a reasonable sense of what is included but not exactly what the agent will receive or how this tree relates to the sibling checker tools. It is minimally viable but leaves room for more explicit guidance.

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 no parameters, so there is no parameter information for the description to add. The description therefore cannot be penalized for missing parameter guidance, and the zero-parameter baseline of 4 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 identifies the resource as the complete decision tree for the Food temperature record checker and enumerates its contents ('every question, option and verdict'). It distinguishes itself from stepwise siblings like checker_answer and checker_start by emphasizing end-to-end coverage, though it lacks an explicit verb like 'returns'.

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 should be used when the agent needs the full decision tree rather than a single step. However, it does not explicitly state when not to use it or name alternatives such as checker_start or checker_answer, leaving routing mostly to inference from sibling names.

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