chrome_navigate

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

No annotations exist, so the description must fully disclose behavior. It only states the action but omits critical details: does it open a new tab, replace current page, load fully before returning? No disclosure of side effects or requirements.

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 is concise and front-loaded with the key verb and object. However, it is too brief and could benefit from additional structure, such as stating prerequisites or return behavior.

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 no parameters, no output schema, and no annotations, the description does not cover essential context: what happens after navigation, return value, error states, or prerequisites. Incomplete for an agent to use confidently.

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?

The input schema has zero parameters, yet the description mentions a URL, which is inconsistent. The description adds context not in the schema (a URL is needed), but the schema omission undermines clarity. Baseline for 0 params is 4, but reduced due to contradiction.

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 action (navigates), target (Google Chrome), and object (URL), but does not differentiate from sibling tools like safari_navigate or web_navigate. It is specific to Chrome, which helps.

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 gives no guidance on when to use this tool vs. alternatives (e.g., web_navigate, safari_navigate) or any prerequisites (e.g., Chrome must be open). No exclusions or context provided.

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