set_d_max_roll

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

No annotations are provided, so the description carries the full burden. It discloses the parameter type (UINT8), default (40), and constraint (≥ d_roll). However, it does not specify side effects, persistence, or validation behavior on constraint violation. For a simple parameter setter, this is adequate but not exhaustive.

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: two sentences with no wasted words. It front-loads the action ('Set d_max_roll') then provides the explanation and constraints efficiently.

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 (one required parameter, no output schema), the description covers purpose, type, default, and a key constraint. It does not mention error handling if the constraint is violated, but overall it is sufficiently complete for a parameter-setting tool.

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% but the description adds significant meaning: explains the parameter as a dynamic damping ceiling for fast moves, specifies the default value (40), and imposes a constraint (≥ d_roll). This goes beyond the schema's generic 'Value for d_max_roll (UINT8)'.

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 explicitly states 'Set d_max_roll' (verb+resource) and explains it as 'Dynamic damping ceiling — D value used during fast moves.' This clearly distinguishes it from siblings like set_d_roll (regular damping) and set_d_max_pitch/yaw (different axes) by specifying the dynamic context.

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 indicates when to use this tool: 'during fast moves' and provides a crucial constraint 'Must be ≥ d_roll'. While it does not explicitly state when not to use or mention alternatives, the purpose is clear enough for an AI agent to select it appropriately among similar set commands.

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