get_d_pitch

Retrieve the pitch D gain value, which is the base derivative term active in smooth flight and boosted on fast maneuvers.

Instructions

Get d_pitch: Base D — active in smooth flight. Boosted toward d_max_pitch on fast moves. [UINT8, default: 34]

Behavior2/5

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

With no annotations, the description must disclose behavioral traits. It implies a read operation but does not mention side effects, authorization needs, rate limits, or any mutability. The type and default hint at configurability but lack explicit transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is one sentence plus a parenthetical note, making it concise and front-loaded. However, technical jargon like 'UINT8' and 'd_max_pitch' may reduce clarity for less domain-expert agents.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no parameters or output schema, the description provides adequate context (value type, default, behavior context of smooth vs fast flight). However, it does not explain what 'd_pitch' fundamentally represents, which could limit understanding for agents unfamiliar with PID terminology.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The tool has no parameters, so the baseline is 4. The description adds value by specifying the returned value's type (UINT8) and default (34), which helps the agent interpret the output. No further parameter information is needed.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool retrieves the 'd_pitch' value, specifies it's a base D active in smooth flight and boosted on fast moves, and provides the data type and default. This distinguishes it from sibling tools by naming the pitch axis, though it assumes domain knowledge about what 'D' represents in PID control.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given on when to use this tool versus alternative get_d_* tools (e.g., get_d_roll, get_d_yaw). There is no explanation of context or prerequisites, leaving the agent to infer usage from the name alone.

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