Browser Navigate

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

With no annotations, the description carries full responsibility for behavioral disclosure. It only states the action without revealing side effects, such as whether the page is loaded asynchronously, whether navigation is awaited, or what happens to the session state. This is inadequate for a tool that changes the browser state.

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 short, but this is under-specification rather than conciseness. It front-loads the action but omits critical guidance, making the brevity detrimental to usability.

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 navigation tool with two parameters and no output schema, a minimal description could suffice if it mentioned expected behavior or constraints. However, the bare sentence leaves the agent uncertain about what constitutes a successful navigation or any failure modes, so it is incomplete.

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%, meaning the schema does not describe the parameters. The description also fails to clarify what 'session page' means or what format the URL should take, leaving both parameters under-specified and forcing the agent to guess.

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) and the resource (session page) with a target URL. However, it does not differentiate from sibling navigation tools like browser_go_back, which also involves navigation, so the purpose is clear but not distinguished.

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. The agent is given no context about prerequisites, restrictions, or cases where another navigation tool would be more appropriate.

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