Betaflight MCP

by bvandevliet

get_dterm_lpf1_static_hz

Retrieve the static cutoff frequency for the D-term low-pass filter 1, applied when dynamic range is disabled. Understand current filter setting for Betaflight tuning.

Instructions

Get dterm_lpf1_static_hz: Static cutoff for D-term LPF1. Used when dterm_lpf1_dyn_min_hz == dterm_lpf1_dyn_max_hz. [INT16, default: 75]

Input Schema

NameRequiredDescriptionDefault

No arguments

Behavior3/5

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

No annotations are provided, and the description does not explicitly state that the tool is read-only or requires no authorization. However, as a getter, it is implied to be safe. The description mentions the data type and default value but lacks behavioral details like side effects or permission requirements.

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

Conciseness5/5

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

The description is extremely concise, using two short sentences to convey the purpose, usage context, and default value. Every piece of information is relevant and no space is wasted.

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

Completeness4/5

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

For a simple getter with no parameters and no output schema, the description covers the purpose and usage condition. It does not describe the return format, but the return is likely a scalar value, which is obvious from the context. Overall, it is fairly complete for a tool of this simplicity.

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 input schema has no parameters, and schema description coverage is 100%. The description does not need to add parameter information. Baseline 4 is appropriate for a zero-parameter tool.

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

Purpose5/5

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

The description clearly states it retrieves the static cutoff frequency for the D-term low-pass filter 1, including the data type and default value. It distinguishes from siblings by specifying the condition when this parameter is used.

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

Usage Guidelines4/5

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

The description provides explicit context on when to use this tool: when `dterm_lpf1_dyn_min_hz == dterm_lpf1_dyn_max_hz`. While it does not list alternatives, the condition helps the agent understand its applicability among many similar getter tools.

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