browser_navigate

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

With no annotations provided, the description adequately covers the return values and the wait-for-page-load behavior. However, it omits details about potential redirects, timeouts, error handling, or what happens if the page fails to load, which leaves gaps in 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 very concise, consisting of two short sentences that convey the essential information without any extraneous words or repetition.

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 simplicity of the tool and that an output schema exists (mentioned in context), the description covers the main action and return values. It could be slightly more complete by mentioning error scenarios or page load behavior, but it is largely adequate.

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 only parameter 'url' is self-explanatory from the tool name and input schema. Schema description coverage is 0%, but the description does not add any additional meaning or constraints beyond what is obvious. A baseline of 3 is appropriate as no extra value is provided.

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 action ('navigate to a URL'), the resource ('a URL'), and what is returned ('final URL, page title, and HTTP status code'). It effectively distinguishes from sibling tools like browser_click or browser_go_back by specifying the core navigation function.

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 browser_go_back or browser_go_forward. The description lacks context about prerequisites or conditions that might warrant using this tool over others.

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