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 disclose the content scope: every question, option, and verdict in the guide. However, it does not describe output format, size, pagination, or whether the data is a static snapshot, which leaves some behavioral uncertainty for a tool that likely returns a large complete tree.

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. It front-loads the resource and scope, then states the intended reasoning use. Every word earns its place.

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?

The description names the content scope and the intended use case, which is adequate for a parameterless retrieval tool. However, with no output schema and no explicit mention of how the returned tree is structured or how this tool relates to checker_start and checker_answer in the larger flow, an agent may not fully know what to expect.

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 description coverage is 100%, so the description has no parameter semantics to add. The empty schema is self-explanatory, and the description appropriately focuses on the tool's content rather than parameters.

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 ('Smoke control checker guide') and the full scope ('every question, option and verdict'), making the tool's purpose reasonably clear. The title reinforces that it exposes the whole decision tree. However, it lacks an explicit action verb like 'returns' or 'loads', so the behavior must be inferred from 'for reasoning end to end.'

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 this tool should be used when the agent needs the entire decision tree rather than stepping through it, contrasting with siblings like checker_start and checker_answer. But the description does not explicitly state when to prefer this over those alternatives, so usage guidance remains implicit.

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