playwright_cli_goto

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

With no annotations, the description carries the full burden of behavioral disclosure. It only states the action (navigate to a URL) and omits critical details such as whether the current page is replaced, how errors are handled, whether the tool waits for page load, or how session and timeout parameters affect behavior. The description is too minimal to be considered transparent.

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, well-structured sentence with the main verb 'Navigate' front-loaded. It contains no unnecessary words and is easy to parse. While it is very brief, the conciseness dimension rewards efficient use of language, and the sentence is appropriately sized for the limited information it conveys.

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?

Despite having an output schema, which may document return values, the description is incomplete for a tool with four parameters and no annotations. It fails to explain the role of optional parameters, the need for an active session, or how the tool fits into a broader workflow. The description alone does not provide enough context for an agent to invoke the tool 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 description coverage is 0%, so the description must compensate. It only mentions 'public URL', which loosely corresponds to the url parameter, but it provides no additional meaning for the other three parameters (session, max_chars, timeout_seconds). It does not explain their purpose, defaults, or how they influence the operation.

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 the specific verb 'Navigate' and identifies the resource as 'the current Playwright CLI page', clearly indicating it changes the URL of an existing page. This distinguishes it from sibling tools like playwright_cli_open (which likely opens a new page) and playwright_cli_snapshot (which captures state), though it does not explicitly mention these alternatives.

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 on when to use this tool versus alternatives. The description does not mention prerequisites (e.g., an already-open page) or exclude scenarios where other tools like playwright_cli_open would be more appropriate. The phrase 'current page' implies an existing session but does not explicitly state this or provide any usage direction.

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