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. It mentions parameters for window resizing and debug mode but fails to describe what the tool actually does behaviorally—e.g., whether it establishes a session, requires authentication, has side effects, or returns any output. This leaves critical operational details unclear.

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 extremely concise—two sentences that directly state the purpose and parameter meanings without any fluff. It is front-loaded with the core action, making it efficient and easy to parse.

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 complexity of initializing a connection (likely involving state changes or setup), no annotations, no output schema, and 0% schema coverage, the description is incomplete. It doesn't explain what happens after initialization, error conditions, or dependencies, leaving significant gaps for the agent to operate effectively.

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%, so the description must compensate. It adds meaningful semantics by explaining that 'resize' controls automatic window adjustment and 'debug' enables debug mode, including their default values. This goes beyond the schema's type information, though it doesn't cover all potential behavioral implications of these parameters.

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 the verb '初始化' (initialize) and the resource '微信连接' (WeChat connection), making the purpose evident. It doesn't explicitly distinguish from siblings like 'wechat_activate' or 'wechat_status', but the action is specific enough to understand its role in setting up a connection.

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?

No guidance is provided on when to use this tool versus alternatives such as 'wechat_activate' or 'wechat_check_activation'. The description lacks context about prerequisites, timing, or exclusions, leaving the agent to infer usage based on the name alone.

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