set_acc_trim_roll

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

No annotations are provided, so the description carries the full burden. It indicates a mutation ('Set') but does not disclose side effects, prerequisites (e.g., arming state), or whether the change is persistent. The range and default are helpful but insufficient for full 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 a single sentence with essential additional details in brackets. It is concise and front-loaded, but the structure could be improved by separating the range info into a bullet or clearer format.

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 simple one-parameter setter with no output schema, the description adequately explains purpose and range. However, it does not mention the corresponding getter (get_acc_trim_roll) or how this fits into the calibration workflow, which could be useful context given the large sibling list.

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 coverage is 100% and the description repeats the type, range, and default already in the schema property description. It adds no new meaning beyond what the schema provides, so baseline 3 applies.

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 verb 'Set', the resource 'acc_trim_roll', and its purpose 'roll trim for level calibration'. This distinguishes it from siblings like set_acc_trim_pitch (pitch trim) and get_acc_trim_roll (read).

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 context (level calibration) but does not explicitly state when to use this tool versus alternatives like calibrate_accelerometer or set_acc_trim_pitch. No exclusions or when-not-to-use guidance is given.

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