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

With no annotations provided, the description carries full burden for behavioral disclosure. It states the action ('navigate to URL') but lacks details on what happens during navigation (e.g., page load waits, error handling for invalid URLs, or whether it follows redirects). For a tool with potential side effects (like changing browser state), this is insufficient transparency.

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 ('导航到指定URL')—a single phrase that directly states the tool's function without any wasted words. It's front-loaded with the core action, making it efficient for quick understanding.

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's moderate complexity (navigation with potential side effects), no annotations, and an output schema present (which might describe return values), the description is minimally complete. It states what the tool does but lacks behavioral details and usage context. The output schema might help, but the description itself is inadequate for full understanding.

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 description adds minimal meaning beyond the input schema, which has 0% description coverage but clearly defines a single required 'url' parameter of type string. The description implies the parameter is a URL to navigate to, but doesn't specify format (e.g., must include protocol like 'http://') or constraints. With one parameter and low schema coverage, this meets the baseline but doesn't compensate fully.

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 '导航到指定URL' (Navigate to specified URL) clearly states the verb (navigate) and resource (URL), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'new_tab' or 'connect_browser' which might have overlapping navigation functions, preventing a perfect score.

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 guidance on when to use this tool versus alternatives like 'new_tab' for opening new tabs or 'connect_browser' for browser setup. There's no mention of prerequisites (e.g., requires an active browser session) or exclusions (e.g., not for internal page navigation), leaving usage context unclear.

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