set_use_vbat_alerts

Enable voltage-based OSD and beeper warnings to monitor battery voltage.

Instructions

Set use_vbat_alerts: Enable voltage-based OSD/beeper warnings. [UINT8, default: ON]

Input Schema

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

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

With no annotations, the description carries the full burden. It only notes a type hint '[UINT8, default: ON]' but fails to disclose critical behaviors such as whether the change is immediate, persistent across reboots, or requires a reboot. The type hint also contradicts the schema (string vs UINT8).

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 short and front-loaded, stating purpose directly. However, it could be more structured with separate lines for type and default, and the inconsistency with the schema reduces clarity.

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

Completeness2/5

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

For a simple setter with one parameter and no output schema, the description still lacks completeness. It fails to explain persistence, immediacy, or interaction with related settings (e.g., 'set_use_cbat_alerts'). The type inconsistency further undermines completeness.

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

Parameters2/5

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

Although schema coverage is 100% (parameter has a description), the description adds a default value but contradicts the schema by specifying 'UINT8' while the schema declares a string type. Valid values (e.g., 0/1 or ON/OFF) are not clarified, limiting parameter understanding.

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 verb 'Set', the resource 'use_vbat_alerts', and the purpose 'Enable voltage-based OSD/beeper warnings'. This uniquely identifies the tool's function among siblings like 'set_use_cbat_alerts' and 'get_use_vbat_alerts'.

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?

The description provides no guidance on when to use this tool versus alternatives (e.g., current-based alerts). It does not mention prerequisites, side effects, or context for invocation, leaving the agent without decision support.

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