# Chaos Engineering Runner Skill

## Overview

Runs chaos engineering experiments using Chaos Monkey, Litmus, or Gremlin including failure injection scenarios, blast radius control, and experiment analysis.

## Capabilities

- Run Chaos Monkey experiments
- Litmus chaos execution
- Gremlin integration
- Failure injection scenarios
- Blast radius control
- Steady state validation
- Experiment rollback
- Results analysis

## Target Processes

- resilience-patterns

## Usage Example

```javascript
{
  kind: 'skill',
  skill: {
    name: 'chaos-runner',
    context: {
      experiment: {
        name: 'pod-failure-test',
        type: 'pod-kill',
        target: {
          namespace: 'production',
          labelSelector: { app: 'api-service' },
          percentage: 50
        },
        duration: '5m'
      },
      framework: 'litmus',
      steadyState: {
        probes: [{ type: 'http', endpoint: '/health' }],
        assertions: [{ metric: 'error_rate', operator: '<', value: 0.01 }]
      },
      options: {
        dryRun: false,
        autoRollback: true
      }
    }
  }
