check_root_status

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

No annotations are present, so the description carries full responsibility for behavioral disclosure. It mentions 'multiple indicators' but does not disclose whether the check is read-only, requires special permissions, affects device state, or has any limitations. For a detection tool, this is insufficient operational transparency.

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 concise and front-loaded with the core purpose. The first sentence is somewhat redundant with the tool name, but the second sentence and the Args line provide useful detail without excess. Overall, it is appropriately sized and easy to parse.

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 tool's low complexity (one optional parameter) and the presence of an output schema, the description is largely complete. It explains what the tool checks and what the parameter means. It does not describe prerequisites like device connectivity or interpretation, but these are not critical for such a simple tool with structured output.

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 0% description coverage, but the description compensates with an explicit Args section: 'device_id: Optional device serial number.' This adds meaningful semantic detail beyond the schema's bare 'Device Id' title and default null, clarifying that the parameter expects a serial number and is optional.

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 function: 'Comprehensive root/jailbreak detection' and 'Checks multiple indicators of device rooting.' This uses a specific verb ('checks') and resource ('device rooting'), and it distinguishes the tool from siblings like extract_with_root (which performs an action using root) and other diagnostic tools.

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 is provided on when to use this tool versus alternatives. The description only states what the tool does, not the conditions under which it should be invoked, nor any prerequisites or exclusions. There is no mention of related tools or specific scenarios (e.g., before extract_with_root).

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