browser_navigate

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

No annotations provided, so description must describe behaviors. It does not mention whether it waits for page load, handles errors (e.g., invalid URL), or any side effects on the active tab. The description is minimal.

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 one sentence with a clear imperative. It is appropriately front-loaded but could be slightly more detailed without becoming verbose.

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 and an output schema existing, the description does not explain return values (e.g., page title) or post-navigation state. For a straightforward navigation, it minimally suffices but leaves gaps.

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 schema has 0% description coverage; the description merely restates 'The URL to navigate to.' for the url parameter, adding no additional meaning or constraints (e.g., format, protocol, relative vs absolute).

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 the active tab to a URL.' It distinguishes from sibling tools like browser_switch_tab (which switches tabs without navigation) and browser_execute_js (which runs JavaScript).

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 guidelines on when to use this tool versus alternatives like browser_batch or browser_scan. No mention of prerequisites (e.g., page must be interactive) or when not to use it.

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