puppeteer_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 fails to mention whether the tool waits for page load, handles redirects, or what happens on network errors. The simple statement 'Navigate to a URL' lacks essential behavioral context.

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 extremely concise at 4 words, which is appropriate for a simple tool. However, it lacks helpful structure and could be improved with a sentence that front-loads the most critical information (e.g., 'Navigates the page to the given URL, waiting for the full page load.').

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?

Given the tool's moderate complexity (navigation involves waiting, loading states, and possible errors), the description is incomplete. It does not address return values, error behavior, or side effects. With no output schema or annotations, the description should cover these aspects but fails to do so.

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 input schema has 0% description coverage, so the description must add meaning. While 'Navigate to a URL' implies the 'url' parameter is the destination, it does not specify required format (e.g., must include protocol), maximum length, or allowed schemes. The description adds little beyond the parameter name itself.

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 'Navigate to a URL' clearly states the action (navigate) and the resource (URL). While it doesn't explicitly differentiate from sibling tools like puppeteer_click or puppeteer_fill, the sibling names are distinct enough that confusion is unlikely.

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, such as prerequisites (e.g., page must be open) or exclusions (e.g., do not use for file:// URLs). Users must infer usage from the tool name alone.

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