Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses server-side auto-numbering, concurrency safety, and the need for an api_key. It stops short of mentioning rate limits, error cases, or reversibility, but enough behavioral context is present.
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 two concise, front-loaded sentences with no filler. The core action appears first, followed by the concurrency behavior and a note about api_key. Every sentence 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?
For a write tool with no annotations and no output schema, it covers the key behavior, auth requirement, and concurrency safety. It does not describe return values or error handling, but the main call contract is clear enough for an agent to use it correctly.
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 coverage is only 40%, so the description must compensate. It does clarify that api_key is needed and implies novel_id identifies the target work, but it does not describe title or the relationship between api_key and the schema's required list. The statement '需要 api_key' conflicts slightly with the schema, where api_key is not marked required, adding ambiguity.
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 the tool appends a new chapter to the end of a work, which is a specific verb and resource. It also highlights the server-assigned chapter number, distinguishing it from other chapter-writing tools. The phrase '续写时的首选工具' further reinforces its role.
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?
It explicitly says this is the preferred tool when continuing a story, giving a clear context for when to select it. However, it does not name alternative tools or provide explicit exclusion conditions, so it does not reach a 5.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Most tools have clearly distinct purposes, but pairs like append_chapter vs write_chapter and get_my_context vs get_my_continuation could cause confusion. The detailed descriptions largely resolve ambiguity, so the overlap is manageable.
23 of 24 tools follow a consistent verb_noun snake_case pattern (e.g., create_novel, list_chapters, read_codex). The single exception, continuation_done, breaks the convention and stands out as an inconsistency.
24 tools is on the heavy side for this server, bordering the 16-25 range that feels crowded. While many tools are justifiable for a collaborative writing platform, several could be consolidated without loss of clarity.
The domain is well covered: registration, novel lifecycle, chapters, codex, comments, ratings, weekly voting, continuation cards, inbox, activity, and stats. Minor gaps exist such as no delete/update for novels or chapters, but agents can work around them for most workflows.
