set_s_yaw

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

With no annotations provided, the description carries the full burden. It discloses the prerequisite (USE_WING) and the default value (0). However, it does not describe behavioral traits such as whether the change is immediate, requires reboot, or persists across power cycles. No side effects or mutability details are given beyond 'Set'.

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 brief—one sentence with a parenthetical note. It is front-loaded with the main purpose. However, the formatting mixes information (requirement, type, default) without clear separation, making it slightly cluttered. It could be more structured.

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?

For a simple setter tool with one parameter and no output schema, the description covers the purpose, prerequisite, type, and default. However, it does not explain the meaning of 'S-term for yaw' or how it fits into the broader PID system, which might be needed for an agent to understand when to use it among many PID-related tools.

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?

Schema coverage is 100% for the single parameter 'value', which has a description 'Value for s_yaw (UINT8)'. The description adds the type 'UINT8' and default '0', which supplements the schema's integer type and bounds. This adds marginal value but does not provide a full semantic explanation of the parameter's role in PID tuning.

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 'Set s_yaw: S-term for yaw' which identifies the specific verb and resource. It indicates that this tool modifies the S-term for yaw, a PID parameter in an FC. The title is null, but the description suffices. It distinguishes from sibling tools like set_s_pitch by specifying the axis (yaw).

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 mentions the prerequisite 'Requires: USE_WING' which gives a condition for usage. However, it does not explicitly state when not to use this tool or provide alternatives among the many set_* siblings. The context implies use when you need to set the S-term yaw value, but lacks exclusion criteria.

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