set_yaw_rc_rate

Set the yaw rate at stick center to control mid-stick yaw responsiveness for Betaflight flight controllers.

Instructions

Set yaw_rc_rate: Yaw rate at stick center. [UINT8, default: 7]

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
valueYesValue for yaw_rc_rate (UINT8)
Behavior2/5

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

No annotations are provided, so the description must fully convey behavior. It only mentions the type (UINT8) and default value, but does not disclose side effects, persistence, or whether this affects the running configuration or saved settings.

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

Conciseness5/5

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

Extremely concise, single sentence with all essential information front-loaded. No wasted words.

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 single-parameter setter, the description is adequate. However, it could explain the concept of 'yaw rate at stick center' and how it relates to overall yaw responsiveness, especially for users unfamiliar with flight controller tuning.

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

Parameters4/5

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

Schema coverage is 100%, but the description adds the default value and the context 'at stick center', which provides meaningful additional information beyond the schema's basic description of the parameter.

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 verb ('Set'), the resource ('yaw_rc_rate'), and the specific meaning ('Yaw rate at stick center'). It distinguishes from sibling tools like set_yaw_srate and set_yaw_rate_limit by focusing on stick center rate.

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 like set_yaw_srate or set_yaw_rate_limit. No prerequisites or conditions for use are mentioned.

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