browser_navigate

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

No annotations are provided, so the description carries full burden. It does not disclose any behavioral traits such as page load behavior, potential side effects, or error handling. The agent is left unaware of what happens after navigation (e.g., waiting for load, security implications).

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 concise: one sentence plus a reference to browser_docs. It is front-loaded with the main action ('Navigate to a URL'). It could be shorter but is efficient.

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 one-parameter tool with no output schema, the description is minimal. It lacks context about navigation behavior (e.g., loading, success/failure indication) and does not leverage the reference to browser_docs effectively within the description itself. More detail is needed for an agent to use it confidently.

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 100% as the url parameter has a clear description. However, the tool description adds no extra meaning beyond what the schema already provides. Baseline is 3, and no additional value is contributed.

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 verb 'Navigate' and the resource 'a URL in the browser'. While it is straightforward and distinguishes from many siblings (e.g., click, type), it relies on a reference to browser_docs for more detail. The purpose is clear but not exceptionally specific.

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 browser_reload, browser_go_back, or browser_new_page. It only directs to browser_docs for more info, which is insufficient for an agent to understand appropriate usage context.

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