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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered by structured data. The description adds only workflow positioning and says nothing about what the generated outline looks like, how many sections it returns, or how project_id or design_type change the output — minimal value beyond annotations.

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?

It is short, but the text is a run of unpunctuated fragments ('生成论文提纲 用户先要提纲/目录/章节结构，再写正文 章节提纲') with a redundant trailing '章节提纲'. It is front-loaded with the core purpose, yet the fragmentary phrasing costs clarity for no compensating gain.

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 three-parameter generation tool with no output schema, the description should explain what an outline contains and how the optional parameters affect it. Instead it repeats outline synonyms, leaving the agent to infer output shape and the role of project_id and design_type.

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%, so all three parameters (title, project_id, design_type) are already documented in the schema. The description adds no additional meaning about how project_id scopes the request or how design_type influences the outline structure, so the baseline of 3 applies.

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 conveys that it produces a paper outline (提纲/目录/章节结构), which is a specific resource, but it largely restates the name and title rather than stating a distinct verb+scope. It does not differentiate this tool from close siblings such as act_writing_one_click or act_write_chapter, which also produce written structure for a paper.

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 '用户先要提纲/目录/章节结构，再写正文' implies sequencing: use this before drafting body text. That is implied usage guidance rather than an explicit when-to-use/when-not-to-use statement, and no alternative tool is named for cases where a full draft is wanted instead of an outline.

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