playwright__browser_navigate

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

Annotations already mark the tool as not read-only, open-world, and destructive, so the safety profile is externally provided. The description itself adds no behavioral detail beyond the basic action, such as page-load waiting, current-page state changes, or side effects, but it is not misleading and does not contradict the annotations.

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 compact phrase with the key verb and object front-loaded. Every token is functional, and there is no excessive prose or redundant elaboration.

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 tool with one required parameter and existing annotations, the invocation requirements are straightforward. However, the description omits context about what happens after navigation, whether the tool waits for the page to load, and how it relates to navigate_back, so an agent must infer this behavior from the tool name and siblings.

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% because the only parameter, 'url', is documented in the schema. The description merely repeats 'URL' and does not add meaning such as accepted URI formats, http/https requirements, or whether relative and absolute URLs are supported, so the baseline of 3 applies.

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 uses a specific verb ('Navigate') and a clear resource ('a URL'), so the core operation is unambiguous. However, it does not explicitly distinguish itself from the sibling playwright__browser_navigate_back or other navigation-related tools, so it misses the differentiation that would earn a 5.

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?

There is no guidance about when to prefer this tool over playwright__browser_navigate_back, playwright__browser_wait_for, or other siblings. The only usage signal is implied by the name and the phrase 'Navigate to a URL', with no exclusions or prerequisites stated.

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