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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It implies a read/check operation through '自检' and '扫描', but never states whether the tool mutates anything, what it returns, whether it requires specific permissions, or what the D-01~D-07 scan actually does to the work/chapter.

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 dense sentence with no filler and front-loads the core concept of '红线自检'. However, the extreme compression relies on unexplained domain jargon, making it under-specified rather than elegantly concise.

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?

There is no output schema, no annotations, and no explanation of return values, D-code interpretations, or expected audit result. For a tool that operates on a specific work_id and chapter_no, an agent lacks enough information to know whether the audit passed, what the D-01~D-07 findings mean, or what action to take next.

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?

Schema description coverage is 100%: both work_id and chapter_no have meaningful Chinese descriptions. The tool description adds no parameter-specific meaning beyond the general audit context, so the baseline of 3 is appropriate because the schema already documents the parameters adequately.

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 states a specific operation: a red-line audit that re-checks BVT dual gates and scans for defects D-01–D-07. However, it relies on unexplained jargon ('BVT', '病灶', 'D-01~D-07') and does not clearly say what the tool does to the supplied work_id and chapter_no, making it only minimally distinguishable from sibling audit-like tools.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives. An agent is not told when to choose redline_audit over rhythm_check or other siblings, and must infer the intended context from the cryptic description.

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