browser_navigate

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

There are no annotations, so the description carries the full transparency burden, but it only says 'navigate to a URL' without disclosing wait behavior, error handling, or page load completion. It also does not mention whether sessionId affects the operation.

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 a single concise sentence with no redundant words. It is front-loaded with the action and directly states the target.

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 browser navigation tool with no output schema, this description is incomplete: it does not explain what happens after navigation (e.g., whether it waits for the page to load, returns success, or errors). It also does not clarify the role of sessionId, and there are related sibling tools that imply additional context.

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 input schema already describes both parameters with 100% coverage, so the description adds little beyond the schema. It mentions 'URL' but does not clarify the purpose or usage of sessionId beyond the schema's short description.

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 tool's function with the specific verb 'Navigate' and resource 'URL in the browser', making it unmistakable. It is not a tautology and distinguishes from sibling tools that handle history or other browser actions.

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 like browser_go_back or browser_wait_for_navigation. The description does not mention exclusions or conditions, leaving the agent to infer usage from the name alone.

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