browser_navigate

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

The description adds essentially no behavioral context beyond the annotations. It does not disclose whether navigation waits for full page load, replaces the current page, preserves state, or fails on invalid URLs. The annotations mark destructive and open-world behavior, but the description offers no additional operational detail.

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 short sentence with no filler or unnecessary detail. It is front-loaded and appropriately sized for a tool with a single parameter.

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 simple one-parameter tool, this is minimally viable, and the annotations partially compensate for missing safety details. However, there is no output schema and the description does not mention return behavior, waiting semantics, or side effects, leaving some ambiguity for an agent.

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?

Schema coverage is 100% and the single 'url' parameter is already described in the schema. The description only repeats 'URL' and adds no additional meaning, format constraints, or edge-case guidance.

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 states a clear verb and resource: 'Navigate to a URL.' However, it does not explicitly differentiate this from sibling tools like browser_navigate_back; an agent may need to infer which navigation tool is intended.

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 when-to-use or when-not-to-use guidance is provided. The description does not mention alternatives such as browser_navigate_back or explain when browser_navigate is the appropriate choice.

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