browse_navigate

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

No annotations are provided, so the description must fully disclose behavioral traits. It mentions the return values (final_url/title/site) but fails to explain side effects, waiting behavior, error handling, or state changes. The wait_until parameter is not described, leaving significant behavioral ambiguity.

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 brief (one sentence), which is concise but at the expense of missing critical information. It is not front-loaded with the most essential details; rather, it is under-specified. Conciseness should not sacrifice necessary clarity.

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 has 3 parameters (one required), no parameter descriptions, and no usage guidance, the description is incomplete. While an output schema exists (reducing need to detail return values), the description fails to cover the input semantics, behavior, or context, making it insufficient for reliable agent use.

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 description coverage is 0%, yet the tool description does not explain any of the three parameters (url, session_id, wait_until). The description only mentions the return fields, adding no semantic value to the input schema. With low coverage, the description should compensate but fails to do so.

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 URL) and the resource (URL), which distinguishes it from the sibling tool browse_click. However, it could be more specific about the context (e.g., browser navigation) and does not elaborate on the return value details beyond listing three fields.

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 browse_click, nor does it specify prerequisites or situationally appropriate use. It is a bare functional statement without comparative context.

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