set_ibat_lpf_period

Adjust the low-pass filter period for the current reading to smooth the OSD current display. Higher values reduce fluctuations.

Instructions

Set ibat_lpf_period: LPF period for the displayed current reading. Higher = smoother OSD current display. [UINT8, default: 10]

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
valueYesValue for ibat_lpf_period (UINT8)
Behavior2/5

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 that the tool sets a parameter but omits behavioral traits such as persistence, side effects, or whether it requires a reboot. The type and default are given but not behavioral details.

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—one sentence with a colon separator plus a note on effect and default. Every word earns its place. No fluff.

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 the simplicity of a single parameter setter and no output schema, the description covers the essential aspects (purpose, effect, type, default). However, it lacks guidance on usage context and potential side effects, which would improve completeness.

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?

Schema coverage is 100%, but the description adds significant meaning: it explains that the parameter is the LPF period for displayed current, its effect on OSD smoothness, and its type and default. This goes beyond the schema's minimal description.

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 the tool's purpose: it sets the LPF period for the displayed current reading. The effect ('Higher = smoother OSD current display') is explained. It is differentiated from sibling tools like get_ibat_lpf_period.

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 explicit guidance on when to use this tool versus alternatives. The description does not mention when to increase or decrease the value, nor does it reference any prerequisites or related settings. The default value hint is provided but not the usage context.

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