browser_navigate

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

The description lacks behavioral details, such as whether it waits for page load, replaces the current page, or handles errors. With no annotations provided, the description should cover these basics but does not.

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 (4 words) and front-loaded with purpose. While it is efficient, it is under-specified; however, for its brevity, it earns a high score.

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 simplicity (one parameter, no output schema), the description omits essential context like page load behavior, error handling, and prerequisites. The presence of many sibling tools demands more clarity.

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 single parameter 'url' has a schema description ('URL to navigate to'). Since coverage is 100%, the description adds no extra meaning beyond the schema, meriting the baseline score of 3.

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 'Navigate to a URL' clearly states the action (navigate) and resource (URL). It distinguishes itself from sibling navigation tools like browser_go_back and browser_refresh by indicating it goes to a specific URL.

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 like browser_go_back or browser_go_forward. The description does not mention prerequisites, such as having a browser open or page load considerations.

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