project_bind

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

Annotations are not provided, so the description carries the full burden of behavioral disclosure. The description mentions it does not change member permissions, which is a positive behavioral constraint. However, it doesn't disclose side effects like what binding actually does to the project state, whether it's reversible, or what the response looks like. The mutation is implied by 'bind' but not detailed.

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, compact sentence in Chinese that is front-loaded with the verb and resource, and includes an important constraint. It is appropriately concise for the tool's apparent simplicity. No redundant or irrelevant information is present.

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?

Given the tool has only 2 parametersamen and no output schema, the description is somewhat minimal but covers the essential action. However, the lack of behavioral detail (e.g., is it idempotent? what errors occur?) and the absence of any guidance on the directory parameter make it slightly incomplete for an agent to call confidently without external knowledge.

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 0%, and the description provides no parameter-level information. The parameter names 'project_id' and 'directory' are self-explanatory in the schema, but the description does not explain what 'directory' refers to (e.g., local filesystem path vs. project-relative path) or whether project_id is a UUID or some other identifier. With 0% coverage, the description should compensate, which it fails to do.

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 states a specific verb ('绑定' meaning bind) and resource ('已加入的项目' meaning joined projects), and clarifies that it does not change member permissions. This distinguishes it from project_init, which likely creates a project, and from memory tools. However, it doesn't explicitly state the purpose of binding (e.g., to make the project available for memory operations), but the core action is clear.

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 implies that the tool is used for projects the user has already joined, which is a usage condition. It doesn't explicitly state when not to use it or name alternatives. It also doesn't mention prerequisites like having the project ID or directory path. Given the sibling list includes project_init, a brief note on when to use init vs bind would improve this dimension.

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