set_yaw_control_reversed

Reverses the direction of the yaw stick input on Betaflight flight controllers.

Instructions

Set yaw_control_reversed: Reverses the direction of yaw stick. [INT8, default: OFF]

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
valueYesValue for yaw_control_reversed (INT8)
Behavior2/5

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

No annotations provided. The description does not reveal side effects, safety implications, or behavior beyond the basic reversal. The mention of INT8 contradicts the string type in the schema, adding confusion.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and includes some redundancy ('Set yaw_control_reversed:'). Could be more structured by clarifying the expected value format.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple setter with one parameter, the description is mostly adequate but missing explicit allowed values and handling of the type mismatch.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, but the description adds a type annotation ('INT8') that conflicts with the schema's string type. It does not explain the allowed values (e.g., ON/OFF) or acceptable formats, reducing clarity.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool reverses the yaw stick direction. It distinguishes from sibling tools like set_yaw_deadband and the corresponding get_yaw_control_reversed.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. No context on prerequisites or recommended scenarios.

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