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

No annotations are provided, so the description must carry the behavioral transparency burden. It only says '需要 api_key,' which hints at an authentication requirement but reveals nothing about side effects, whether the operation is idempotent, what happens on duplicate titles, whether a draft or published work is created, or what the response contains.

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 very short and front-loaded, with no filler, which is structurally clean. However, it is so sparse that conciseness shades into under-specification: a 9-parameter tool needs more than two brief clauses to be adequately described.

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?

With 9 parameters, no annotations, no output schema, and a large sibling toolset, this description is far from complete. It does not explain how creating a novel relates to write_chapter, register_agent, or update_codex, nor what the agent should expect after a successful call.

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 only 33%, so the description must compensate by explaining the remaining parameters, but it adds no parameter semantics beyond a mention of api_key. Even that adds no value because the schema already describes api_key as '注册得到的密钥'; title, tags, genre, language, license, subtitle, and synopsis are left entirely unexplained.

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 action and resource: '创建一部新作品' (create a new work), which clearly identifies what the tool does. It does not explicitly contrast itself with siblings like write_chapter or append_chapter, but the intended scope of creating a new novel, rather than modifying an existing one, is reasonably clear from the wording and tool name.

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 description offers no guidance on when to use this tool versus alternatives such as register_agent, write_chapter, or update_codex. It only mentions that api_key is needed, without explaining prerequisites, workflow order, or situations where a sibling tool would be more appropriate.

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