set_landing_disarm_threshold

Set the accelerometer impact threshold for automatic disarm on landing, enabling GPS Rescue and EZ Landing to detect safe landing and disarm.

Instructions

Set landing_disarm_threshold: Accelerometer impact threshold for auto-disarm on landing (used by GPS Rescue and EZ Landing). 0 = disabled. [UINT8, 0–250, default: 0]

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
valueYesValue for landing_disarm_threshold (UINT8, 0–250)
Behavior2/5

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

No annotations are provided, so the description carries full burden. It discloses the valid range, default, and that 0 disables, but does not mention side effects, persistence, or if a reboot is required. This is minimal behavioral disclosure for a setter tool.

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 a single line with essential information: purpose, context, range, default. No waste, front-loaded with key details.

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?

Given no output schema and a simple single-parameter input, the description covers purpose, range, default, and use context. It does not describe return values, but that is typical for a setter and the completeness is adequate.

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 value by explaining what the parameter controls (impact threshold), indicating 0 disables, and providing units and default. This goes beyond the schema's bare 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 verb 'Set', the resource 'landing_disarm_threshold', and explains its purpose (accelerometer impact threshold for auto-disarm on landing) and context (used by GPS Rescue and EZ Landing). It distinguishes from other set_* tools by specifying the exact parameter.

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

Usage Guidelines3/5

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

The description mentions the parameter is used by GPS Rescue and EZ Landing, giving implicit context, but does not explicitly state when to use this tool vs alternatives or provide conditions/exclusions. The guidance is minimal.

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