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

Annotations already provide idempotentHint=true and destructiveHint=false, and the description does not contradict them. The description adds a return envelope format ({success, data, message, error_code?}) and action semantics, but it does not disclose side effects such as launching a GUI application, blocking on QR code scanning, or requiring the IDE to be installed/running. With annotations covering safety, a 3 is appropriate.

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 exactly two sentences: the first states the overall purpose, the second lists actions and the return format. There is no filler, repetition, or unnecessary detail. The structure is front-loaded and every sentence earns its place.

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?

This is a multi-action tool with 10 parameters, and the description does not map parameters to specific actions (e.g., open requires project_path, login uses qr_format/result_output). It also omits prerequisites and likely failure modes. The one-line JSON envelope covers the output shape, but for a lifecycle manager of this complexity, the description is incomplete.

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 tool description only adds semantic meaning to the action enum by explaining what each action does. It says nothing about project_path, port, qr_format, qr_output, cdp_port, or result_output, which are all documented in the schema but not compensated for at the description level. Given schema_description_coverage is 0%, the description should carry more weight for parameters but does not.

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 identifies the tool as WeChat Developer Tools IDE lifecycle management and enumerates six specific actions (open, login, is_login, close, quit, status) with brief semantic labels for each, such as '打开IDE/项目' and '扫码登录'. This makes it easy to distinguish from sibling tools like wechat_build or wechat_inspector, which target different aspects of the WeChat toolchain.

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 no explicit guidance on when to use this tool versus siblings. It does not mention alternatives, exclusions, prerequisites, or conditions such as 'use wechat_build for compilation' or 'use wechat_inspector for debugging'. The action list implies capability but does not help an agent decide between lifecycle management and other tool categories.

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