navigate

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

With no annotations provided, the description gives no information about side effects, waiting behavior, error handling, or what happens to the current page state. The phrase 'Navigate to a URL' is too shallow to convey the actual runtime behavior.

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, clear sentence with no unnecessary words. It is well-structured for a simple action.

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?

The description is minimal and does not mention whether navigation waits for full page load, whether it returns a status, or how errors (e.g., invalid URL) are handled. While the tool is simple, the lack of these details makes it incomplete for an agent to fully anticipate outcomes.

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 'url' parameter has no description in the schema or in the tool description. With 0% schema coverage, the description adds no meaning to what constitutes a valid URL or how it is interpreted (e.g., absolute vs relative).

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) and the target (browser page or mobile app) along with the input (URL). It is specific and easily understood without ambiguity.

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 on when to use this tool versus alternatives like click_element or get_content. The purpose implies navigation, but the description does not provide any contextual cues or decision heuristics for when this tool is the appropriate choice.

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