set_p_roll

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

No annotations provided, so description carries full burden. Mentions UINT8 range and default, but does not disclose persistence, whether changes take effect immediately, or require re-arming. Lacks details on side effects.

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?

Very concise: three short sentences covering purpose, effect, and type/default. Front-loaded with key information, no wasted words.

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 single-parameter tool with no output schema, the description is fairly complete. It explains what the parameter does and the consequence of extreme values. Lacks only behavioral details like immediate vs persistent effect.

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% with a basic description of 'value'. The tool description adds domain context 'Roll P gain' and the effect of high values, improving understanding beyond schema.

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?

Clearly states 'Set p_roll: Roll P gain. Reacts to angle error.' This is a specific verb-resource pair that distinguishes from sibling tools like set_p_pitch and set_p_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?

Hints at consequence of too-high value ('fast oscillations on sharp moves') but does not explicitly state when to use or when not to use this tool vs alternatives. No guidance on prerequisites or typical scenarios.

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