wechat_navigate

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

Annotations already carry idempotent/non-destructive flags, and the description adds the navigation-and-wait behavior plus the exact JSON return contract. It does not detail side effects like page-state changes or failure cases, but for an idempotent navigation tool the disclosure is adequate.

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?

Three front-loaded sentences convey action, applicability, prerequisite, and return shape with no redundant filler. The structure is easy to scan.

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 parameter-rich CDP tool, the definition covers the prerequisite, use cases, and return contract while annotations cover safety/idempotency. It is missing only explicit disambiguation from siblings and error/failure behavior, which are not critical given the output schema and schema-level parameter docs.

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 prose only refers abstractly to '指定页面' and '指定时间' and does not document parameters itself. However, the nested schema fully describes page_path with a query-parameter example, timeout/wait_ms ranges, and clear_logs/check_data behavior, so an agent can still invoke the tool correctly without relying on the description.

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?

States a precise action—'跳转到指定页面' plus CDP log capture—and binds it to concrete use cases (onLoad/onShow lifecycle checks, page error verification). This is specific enough to tell wechat_navigate apart from siblings like wechat_screenshot or wechat_inspector.

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?

Explicitly gives the prerequisite call to wechat_automator with cdp_enabled=true and names the intended scenarios. It does not state when to prefer a different tool or define exclusions, so it stops short of a 5.

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