navigate_to_url

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

No annotations are provided, so the description is the sole source of behavioral insight. It only mentions navigation without disclosing side effects, authentication needs, or irreversible actions. This is insufficient for an agent to fully understand the tool's impact.

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 sentence that conveys the core purpose and a critical usage warning. It is concise without unnecessary information, earning its place through clarity and brevity.

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?

Given the legacy status and the clear alternative, the description is adequate for an agent to decide not to use it. However, it omits any description of return values or what happens after navigation (e.g., page load state). For a complete understanding, more detail would be beneficial.

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%, and the input schema already describes each parameter adequately (e.g., session_id, url, wait_until, timeout). The description does not add any new semantic meaning beyond what the schema provides, so it meets the baseline but adds no extra value.

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's action: navigating to a URL in an existing browser session. It also distinguishes itself from the sibling tool navigate_and_scrape by marking itself as legacy and recommending the alternative, which helps the agent understand its role.

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 explicitly advises to use navigate_and_scrape instead, providing clear guidance on when not to use this tool. However, it does not elaborate on specific scenarios where this tool might still be preferred (e.g., when you already have a session and want minimal overhead).

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