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

With no annotations provided, the description carries the burden; it reveals the action (add) and the optional folder behavior. However, it does not disclose potential side effects, duplicate handling, or failure behavior, leaving some uncertainty for a mutation tool.

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 entire description is one concise Chinese sentence that front-loads the purpose ('将网页或微信文章 URL 添加到知识库') followed by the key exception ('添加到根目录时省略 folder_id'), with zero redundancy.

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 tool with 3 parameters and no output schema, the description covers the core operation, the input limits, and the folder_id semantics. It would benefit from mentioning return behavior or error conditions, but it is sufficient for basic usage.

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?

The schema already documents all 3 parameters with full descriptions (100% coverage), so the baseline is 3. The description adds value by clarifying when to omit folder_id, which is not explicit in the schema alone, earning a 4.

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 'Add web page or WeChat article URLs to the knowledge base' and specifies the 1-10 URL range, making the tool's purpose distinct from sibling read/search tools and the file upload tool.

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 states when to use the tool (importing URLs) and provides a concrete conditional rule: omit folder_id when adding to the root directory. While it doesn't explicitly name alternatives, the purpose and constraints effectively guide selection.

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