set_use_unsynced_pwm

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explains the effect (unsynchronized PWM) and specifies the data type (UINT8) and default (OFF). While it doesn't detail side effects or permissions, it adds meaningful context beyond the raw schema.

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 extremely concise, consisting of a single sentence that front-loads the purpose. Every phrase is informative and there is no redundant or unnecessary wording.

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 with one parameter and no output schema, the description provides adequate context: the action, the effect, primary use case, data type, and default. It could be improved by specifying the range of acceptable values, but overall it is sufficiently complete.

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 schema description coverage is 100%, so baseline is 3. The tool's description adds context that the parameter is for unsynchronized PWM with a default of OFF, but it does not clarify valid values beyond the type. This adds some meaning but not substantial new parameter semantics.

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 the action 'Set use_unsynced_pwm' and explains it sends motor PWM unsynchronized to the PID loop, primarily for brushed motors. This distinguishes it from other setter tools by specifying its unique function and target use case.

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 notes 'Primarily for brushed motors,' giving a clear context for when to use this tool. However, it does not explicitly state when not to use it or provide alternatives among the many sibling setter tools.

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