Navigate to URL

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

Annotations only declare readOnlyHint=false and openWorldHint=true; the description earns credit by disclosing return values and, crucially, that console and network logs are reset — a destructive side effect the annotations don't convey. It stops short of tying that to get_console_errors/get_network_requests or noting error/timeout 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?

Three short sentences, action first, then return values, then side effect — no filler and everything front-loaded.

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, the description usefully names the returned status code, final URL, and title, and flags the log reset. It omits failure modes (invalid URL, timeout behavior) and whether the page state is otherwise preserved, but an agent has enough to call it correctly.

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%, including the enum and the networkidle hang warning, so the schema already carries parameter meaning. The description adds nothing about url, timeout, or waitUntil, making the baseline 3 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?

States a specific verb and resource ("Navigate the active browser page to a URL") and adds what the call returns plus a notable side effect. No sibling competes for navigation, so the lack of explicit sibling differentiation costs nothing.

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?

Usage is only implied: the phrase "active browser page" hints a page must already exist, but the description never says when to prefer this over wait_for or get_page_snapshot, nor what to do if navigation fails. No exclusions or prerequisites are stated.

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