browser_navigate

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

No annotations are provided, so the description must carry the full burden of behavioral transparency. It labels itself as 'Advanced compatibility tool' but does not disclose specific behaviors such as error handling, authentication requirements, or what happens after navigation. Minimal behavioral context beyond the basic action.

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?

Two concise sentences with no wasted words. The first sentence states the purpose, and the second provides usage guidance. Efficient and front-loaded.

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 three parameters, no output schema, and no annotations, the description covers the essential purpose and provides an important usage hint about an alternative. However, it does not describe what happens after navigation (e.g., page load behavior) which could be relevant for an agent. Sufficient but not exhaustive.

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 67% (2 out of 3 parameters have descriptions). The tool description adds no additional meaning beyond what the schema already provides. Baseline is 3 because schema does the heavy lifting; no extra value added.

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?

Clearly states it navigates to a public URL via cloud browsing. Distinguishes itself by specifying a preferred alternative (sa2_open_target with type=cloud) for simpler agent behavior, which differentiates it from sibling tools like browser_navigate_back or browser_reload.

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?

Explicitly tells when to use an alternative tool: 'Prefer sa2_open_target with type=cloud for simpler agent behavior.' This provides clear guidance on when not to use browser_navigate.

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