browserbase_stagehand_navigate

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

No annotations provided, so description carries the behavioral burden. It discloses the action (navigate to URL) and adds reliability guidance. However, it doesn't specify loading behavior, timeouts, or error handling, which are minor for a basic navigation tool.

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 sentences with no redundancy. First sentence states the purpose, second gives usage guidelines. Efficient and well-structured.

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 one parameter and no output schema, the description is complete. It covers purpose, usage, and an edge case (unreliable URLs). Minor omission: does not state that navigation changes the current browser context for subsequent actions, but that's implicit.

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 schema already covers 100% of parameters with a description. The description adds value by warning about URL reliability and suggesting a fallback URL, which provides context beyond the schema.

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 a URL in the browser.' It distinguishes this tool from siblings like screenshot, extract, act, etc., which have different purposes.

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 advises when to use the tool (with URLs that are stable and up-to-date) and provides a fallback strategy (use google.com as starting point), effectively guiding the agent's decision.

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