navigate_to_page

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

There are no annotations, so the description carries the full burden of behavioral disclosure. It only states the basic navigation action and omits crucial details like whether the browser must be pre-initialized, whether the page load waits for completion, what happens on failure, or any side effects. The waitForSelector parameter is not mentioned in the description, leaving the agent unaware of optional 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?

The description is a single, concise sentence of six words. It is front-loaded and free of redundancy, with every word contributing to the core meaning. No unnecessary fluff or repetition.

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 2-parameter tool with no output schema and no annotations, the description is too sparse to provide complete context. It does not explain the expected return value, the relationship to other browser lifecycle tools, or the effect of the optional waitForSelector. The agent is left to infer these details from the schema and sibling names, which is insufficient for a complex scraping workflow.

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% — both 'url' and 'waitForSelector' have clear descriptions in the schema. The tool description adds no additional semantic value beyond the schema, which already documents the parameters adequately. Therefore, the baseline score of 3 is 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?

The description 'Navigate browser to a specific URL' uses a specific verb (navigate), resource (browser), and target (URL), clearly distinguishing this tool from siblings like initialize_browser, take_screenshot, and close_browser. It precisely communicates the core action without ambiguity.

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 no guidance on when to use this tool versus alternatives, prerequisites such as initializing the browser first, or conditions that might require waiting for a selector. The usage is only implied by the tool's name and basic action, offering no explicit context or exclusions.

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