puppeteer_navigate

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

No annotations are provided, so the description bears full responsibility for disclosing behavioral traits. It only notes session behavior and the fact that it gets page content/title, but lacks details on timeouts, error handling, navigation failure behavior, or what happens with redirects. This is insufficient for a navigation tool.

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: two sentences with no redundant information. Every word serves a clear purpose, making it easy to parse quickly.

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 lack of annotations and no output schema, the description should provide more context about the return value, error scenarios, prerequisites (e.g., must have a browser session), and constraints. It only covers session management and basic purpose, leaving significant gaps for an agent to use it reliably.

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%, so the baseline is 3. The description adds minimal extra value beyond the schema: it reiterates the sessionId behavior. It does not explain the waitUntil parameter or url format beyond what the schema already provides, so no bonus points.

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 tool's purpose: 'Navigate to a URL and get the page content/title.' This identifies the action (navigate) and the resource (URL) distinctly, and it differentiates from sibling tools like puppeteer_click or puppeteer_screenshot, which have different purposes.

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 guidance on session reuse: 'If sessionId provided, uses existing session. Otherwise creates a temporary session.' This helps the agent decide when to pass a session ID. However, it does not explicitly mention when to use this tool versus alternatives (e.g., using get_page_content without navigation), though the context is largely implicit.

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