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

Beyond the annotations, it clarifies that ACCEPT only signals willingness to discuss details and explicitly disclaims contractual commitment ('接受并非签约或承诺收益'). It also explains WITHDRAW as withdrawing a pending request. Some side-effect detail remains implicit, but the added context is meaningful.

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 compact and front-loaded: it states the invocation condition first, then maps each action to its meaning, and ends with an important non-contract disclaimer. Every sentence adds necessary value with no filler.

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 simple two-parameter mutation tool, the description covers all action semantics, role conditions, and a non-obvious consequence. The main gap is that it does not explicitly state that id refers to the cooperation request or describe what state the request moves to after each action.

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?

With 0% schema description coverage, the description carries the burden for parameters. It fully explains the action enum semantics and role applicability, but the id parameter is only implicitly the cooperation request id and is not explicitly documented.

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 names the resource (合作请求) and defines each action (ACCEPT/DECLINE/WITHDRAW) with actor-specific meaning. It is specific enough to understand what the tool does, but it does not explicitly distinguish this tool from similarly named siblings such as respond_cooperation_proposal or respond_collaboration_invite.

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 gates usage on an explicit user decision ('用户明确决定后调用') and assigns actions to the correct party: recipient ACCEPT/DECLINE, initiator WITHDRAW. It provides clear invocation context but does not mention exclusions or alternative tools.

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