get_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 burden. It implies a read-only operation ('Get') but does not explicitly state that it returns the current value without side effects. The type, range, and default info add some behavioral context, but it could be more explicit about return behavior.

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 extremely concise—one sentence with no superfluous information. It efficiently conveys tool purpose, value semantics, and constraints.

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?

Despite no parameters or output schema, the description covers the essential aspects: purpose, value type, range, and default. It could be improved by linking to calibration flow or mentioning that this is a read-only query for a specific trim setting.

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 schema has no parameters, so coverage is 100%. The description adds meaningful context about the parameter data type (INT16), valid range (-300 to 300), and default (0), which goes beyond the empty schema and helps the agent understand the value semantics.

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 it gets the accelerometer roll trim for level calibration, explicitly naming the resource (roll trim) and distinguishing from sibling 'get_acc_trim_pitch'. The inclusion of data type, range, and default value provides complete 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?

The description does not provide guidance on when to use this tool versus alternatives such as 'set_acc_trim_roll' or 'calibrate_accelerometer'. No conditions or exclusions are mentioned, leaving the agent to infer usage context.

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