set_crash_delay

Set the delay after arming before crash detection activates. Accepts integer values from 0 to 500 milliseconds.

Instructions

Set crash_delay: Delay after arm before crash detection is armed. [UINT16, 0–500, default: 0 (per profile)]

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
valueYesValue for crash_delay (UINT16, 0–500)
Behavior2/5

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

With no annotations, the description carries full burden. It discloses the value range and default, but fails to mention behavioral traits like persistence, reboot requirements, or side effects on crash detection behavior. This is insufficient for a write operation.

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, consisting of a single sentence that front-loads the action and key details. No extraneous words or repetition.

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?

For a simple parameter setter, the description provides the essential purpose, type, range, and default. However, it lacks behavioral context such as whether the setting persists, requires a restart, or interacts with other parameters. Given the schema covers the parameter, completeness is moderate.

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

Parameters3/5

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

Schema coverage is 100%, providing a baseline of 3. The description adds the default value and 'per profile' context, which is not in the schema. However, the schema already describes the parameter adequately, so the extra value is marginal.

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' and the resource 'crash_delay', defines it as a delay after arm before crash detection is armed, and specifies the type, range, and default. It effectively distinguishes from the sibling get_crash_delay tool.

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 usage guidance is provided. The description does not indicate when to use this tool versus alternatives, nor does it mention prerequisites or contexts such as arming states or profile selection.

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