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

With no annotations provided, the description carries the full burden of behavioral disclosure. The description mentions 'manually add endpoint information' which implies a write/mutation operation, but doesn't disclose any behavioral traits: it doesn't mention whether this requires authentication, what permissions are needed, whether the operation is idempotent, what happens on success/failure, or any rate limits. The description provides only the basic action without behavioral context.

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 in Chinese that's appropriately concise. It's front-loaded with the core instruction and doesn't contain unnecessary information. While it could potentially benefit from more detail, what's present is efficiently stated without waste.

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 1 parameter, no annotations, and no output schema, the description is incomplete. It mentions the context (RapidAPI pages) and action (adding endpoint information) but doesn't explain what format the endpoint information should be in, what the tool returns, or provide enough context for an AI agent to understand when and how to use this tool effectively. The description leaves significant gaps given the tool's complexity and lack of supporting structured data.

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 has 1 parameter with 100% description coverage ('参数' meaning 'parameter'), but the schema description is minimal. The tool description doesn't add any parameter-specific information beyond what the schema provides - it doesn't explain what the 'param' parameter should contain, how it relates to adding endpoint information, or provide examples. With high schema coverage, the baseline is 3, and the description doesn't enhance parameter understanding.

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 '请根据 RapidAPI 页面手动添加端点信息' translates to 'Please manually add endpoint information based on the RapidAPI page.' This is vague about what the tool actually does - it mentions adding endpoint information but doesn't specify what action is performed (create, update, register, etc.) or what resource is affected. While it's not a tautology with the name 'api_endpoint', it lacks a clear verb+resource specification.

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 provides minimal guidance: it suggests using the tool when working with RapidAPI pages to add endpoint information. However, it doesn't specify when to use this tool versus alternatives (though there are no sibling tools), what prerequisites might be needed, or any specific contexts where this tool is appropriate versus other approaches. It offers only implied usage context without explicit guidance.

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