set_i_yaw

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

The description only states the function and provides a hint on type and default ('[UINT8, default: 80]'). There is no disclosure of side effects (e.g., persistence, need to save/reboot, validation beyond schema bounds). With no annotations, the description fails to inform about behavioral traits.

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 very concise (one line) and includes essential info (type and default). It could be improved by adding behavioral notes, but for a simple setter, it is efficient with no redundancy.

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?

Given the tool's simplicity and the schema's coverage, the description is minimally adequate. However, it lacks information on persistence, save/reboot requirements, and the relationship to other PID settings. For a tuning parameter, this context would be helpful.

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 input schema covers 100% of the parameter with a description, but the description adds the default value (80), which is not in the schema. This additional info aids the agent in choosing appropriate values, making the description valuable beyond schema alone.

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 'Set i_yaw: Yaw I gain' clearly states the action and the resource (i_yaw, which is the yaw axis integral gain). However, it does not differentiate this from other set_* tools for PID gains (e.g., set_i_pitch) beyond the parameter name, so purpose clarity is good but not exceptional.

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?

No guidance is provided on when to use this tool versus alternatives like get_i_yaw or other set_* tools. The description lacks any context for usage, leaving the agent without direction on selecting this tool over similar ones.

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