android_uiautomator_toggle_checkbox

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

No annotations are provided, so the description carries full burden. While 'toggle' implies a state change (mutating the checkbox), the description doesn't disclose behavioral traits like whether this requires specific permissions, what happens if the element isn't found, if it waits for UI stability, or what the expected outcome is. It's minimally descriptive for a mutation operation.

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, efficient sentence with zero wasted words. It's appropriately sized for a simple tool and front-loads the core functionality immediately.

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 mutation tool with no annotations and no output schema, the description is insufficient. It doesn't explain what 'toggle' means in practice (e.g., checks if unchecked, unchecks if checked), error conditions, or return values. Given the complexity of UI automation and lack of structured data, more context is needed.

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 description coverage is 100%, so the schema already documents both parameters (resourceId and deviceSerial) adequately. The description doesn't add any meaningful parameter semantics beyond what's in the schema, such as format examples or constraints, meeting the baseline for high schema coverage.

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 ('toggle') and target ('checkbox element by resource ID'), providing a specific verb+resource combination. However, it doesn't distinguish this tool from similar sibling tools like android_uiautomator_click or android_uiautomator_double_click that might also interact with UI elements.

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. There's no mention of prerequisites (e.g., needing an active Android session), when not to use it, or how it differs from other UI interaction tools in the sibling list.

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