navigate

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

With no annotations, the description carries the burden of disclosing behavior. It explains that by default it waits for readyState==='complete', and that wait=False returns immediately after Page.navigate is sent. This is meaningful transparency, though it doesn't mention error handling, timeout behavior, or side effects.

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 short and front-loaded with an example. However, the inclusion of 'loaded' alongside 'wait' creates ambiguity and slightly undermines clarity. Still, it is efficient overall.

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 tool has 4 parameters and no output schema, so the description should explain return values and edge cases. It covers the core waiting behavior but omits return type, timeout behavior, and the role of the tab parameter. This is a noticeable gap for a navigation tool.

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 0%, so the description must compensate. It explains the 'wait' parameter semantics (wait=False immediate return) and provides a URL example, but does not describe 'tab' or 'timeout' parameters. The mention of 'loaded' adds confusion and is not in the schema.

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 navigates to a URL, with a specific example and explanation of default wait behavior. It distinguishes itself by detailing the waiting semantics, though it doesn't explicitly differentiate from sibling navigation tools like new_tab or http_get.

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 implied: you call navigate to go to a URL. The wait parameter behavior gives context on when to use default vs immediate return, but there is no explicit guidance on when to prefer this over alternatives or any exclusions.

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