browser_navigate

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only restates the core action and tab default but does not disclose whether navigation waits for page load, updates history, can fail on invalid URLs, or how to confirm completion. This is thin for a page-changing 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?

The description is a single, front-loaded sentence with no filler. It is efficient and readable, though it sacrifices behavioral context for brevity, so it does not warrant a 5.

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?

With no output schema or annotations, the description should explain post-conditions such as page-load waiting, navigation success/failure, and whether to pair with browser_wait_for. It provides none of this, leaving an agent under-informed for a core browser action.

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 coverage is 100% and all parameters already have meaningful descriptions, including tabId's active-tab fallback and agentId's routing behavior. The description adds no parameter-specific detail beyond the schema, so the baseline score of 3 is appropriate.

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 states a specific verb (Navigate), a resource (URL), and a scope (specified tab or active tab). This clearly distinguishes it from sibling navigation tools like browser_navigate_back, browser_navigate_forward, and browser_reload, which operate differently.

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 explicit guidance is given about when to use this tool versus alternatives. It does not mention that browser_navigate_back/forward are for history navigation, or when active-tab navigation is insufficient. The agent must infer usage from the name and schema.

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