chrome_navigate

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

With no annotations, the description should compensate by disclosing behavioral traits. It fails to mention what happens when no URL is provided, whether it navigates the current tab or opens a new one, or any error conditions.

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, but it sacrifices necessary details for brevity. It is front-loaded with the verb, which is good, but could be improved by adding key usage information.

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 navigation tool with no parameters and no output schema, the description should explain how the navigation target is specified and what the effect is (e.g., new tab vs. current tab). It lacks this essential context.

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; the description does not explain how the URL is determined (e.g., from context or an implicit input). This is a gap for a tool that presumably requires a URL to function.

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) and resource (Google Chrome to a URL), making the tool's purpose understandable. However, it does not specify how the URL is provided given the empty input schema, which slightly reduces clarity.

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?

No guidance on when to use this tool versus alternatives like safari_navigate or chrome_go_back. The agent is left without context to choose appropriately among sibling tools.

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