Navigate

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states 'navigates' without mentioning what happens after navigation, whether it waits for page load, handles errors, or modifies the current page state in a way an agent should know about.

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 succinctly communicates the core action and the only parameter, making it appropriately sized for a one-parameter tool.

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 single-parameter tool, the description is mostly adequate for invoking the tool. However, with no output schema and no annotations, it leaves the expected return value or post-navigation behavior unspecified, which is a gap in completeness.

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 the one parameter comprehensively with a description for 'url.' The tool description adds no meaningful parameter semantics beyond what the schema provides, so it stays at the baseline for high schema coverage.

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 clear action and resource: 'Navigates to a specific URL.' It is specific enough to convey the tool's function, though it does not explicitly distinguish itself from sibling tools like getPageContent or click beyond the core navigation verb.

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 usage is implied: use this tool when you want to navigate to a URL. However, it does not provide explicit guidance on when not to use it, mention prerequisites, or contrast it with alternative tools such as click or fillForm.

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