set_pidsum_limit_yaw

Clamps total yaw PID output to limit yaw authority. Set to 1000 during initial tuning to allow higher yaw response.

Instructions

Set pidsum_limit_yaw: Clamps total yaw PID output. Set to 1000 during initial tuning; default 400 limits yaw authority. [UINT16, default: 400]

Input Schema

NameRequiredDescriptionDefault
valueYesValue for pidsum_limit_yaw (UINT16)
Behavior3/5

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

No annotations provided. Description discloses that the tool clamps yaw PID output and mentions default/tuning values, but does not cover side effects like whether changes take effect immediately or require reboot.

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: two sentences front-loading purpose and usage. No extraneous text, every sentence earns its place.

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

Completeness4/5

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

For a single-parameter setter, the description is adequate: explains function, default, and tuning use. Lacks mention of persistence or immediate effect, but overall sufficient.

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 value beyond schema by recommending specific values ('Set to 1000 during initial tuning') and stating the default, aiding parameter selection.

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 sets the pidsum_limit_yaw parameter, which clamps total yaw PID output. It distinguishes from siblings by specifying 'yaw' and provides context with default and tuning values.

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

Usage Guidelines3/5

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

Provides usage guidance: 'Set to 1000 during initial tuning; default 400 limits yaw authority.' However, it does not explicitly compare to set_pidsum_limit (generic) or state when not to use this tool, lacking alternative differentiation.

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