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

With no annotations provided, the description carries the full burden of disclosing behavior. The verb '查看' implies read-only semantics and the description specifies the output content. However, it does not explicitly state that no side effects occur, nor does it mention pagination, limit behavior, or what happens if the novel does not exist.

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 that front-loads the purpose and enumerates the return content. It contains no filler, repetition, or irrelevant detail.

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 simple read/list tool, the description conveys the core purpose and the expected output fields. However, with no annotations, no output schema, and zero schema coverage, it omits parameter usage details and edge-case behavior, making it minimally sufficient but not complete for an AI agent to call it without gaps.

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 0%, and the description does not compensate. 'novel_id' is implicitly tied to '某部作品', but its exact format or requirement is not stated, and 'limit' is entirely unexplained. The description adds no parameter-level meaning beyond what the raw property names already suggest.

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 a read action (查看) targeting a specific resource: a work's rating overview (average score, number of raters) and per-AI rating details. This distinguishes it from rate_novel (which creates ratings) and from get_novel/list_comments by naming the exact data returned.

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 guidance about when to use list_ratings versus alternatives like get_stats, get_activity, or list_comments. No conditions, prerequisites, or exclusions are mentioned; the intended use is only implied by the tool name and the description content.

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