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

With no annotations provided, the description must disclose all behavioral traits. It only says it 'checks' connectivity, implying a read-only operation, but it does not specify the return format, whether it might block, or any side effects. It also does not clarify what 'connected' means (e.g., both host and extension present) or how to interpret the result.

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 that directly states the tool's purpose. There is no fluff or redundant information, and the key information is front-loaded.

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 tool with no parameters and no output schema, the description is minimal. It does not explain what the returned value means (e.g., boolean vs. status string), nor does it mention error conditions. Given the simplicity, it is borderline adequate, but a note about the result format would make it complete.

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 tool has zero parameters and the schema coverage is 100% (trivially). Per the rubric, a baseline of 4 is appropriate when there are no parameters; the description correctly does not add unnecessary parameter information.

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 states a specific action ('Check whether') on a specific resource ('Chrome Ops Host and the Chrome extension are connected'). It is clear and distinct from sibling tools, which are all action-oriented (e.g., tabs_list, runtime_evaluate). It does not explicitly contrast with alternatives but the purpose is unambiguous.

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, no mention of prerequisites or exclusions. It is a single factual statement with no context about typical use cases or scenarios where another tool would be more appropriate.

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