Overview
chaos-engineer is an open-source testing skill for Claude Code and compatible agents, published by Jeffallan. Its author describes it as: “Designs chaos experiments, creates failure injection frameworks, and facilitates game day exercises for distributed systems — producing runbooks, experiment manifests, rollback procedures, and post-mortem templates. U…”. The project has 11k stars on GitHub and is available under the MIT license. Add it to your setup with `/plugin marketplace add Jeffallan/claude-skills`.
What chaos-engineer does
- Designing and executing chaos experiments - Implementing failure injection frameworks (Chaos Monkey, Litmus, etc.) - Planning and conducting game day exercises - Building blast radius controls and safety mechanisms - Setting up continuous chaos testing in CI/CD - Improving system resilience based on experiment findings
What’s inside
The SKILL.md for chaos-engineer is organised into these sections:
- When to Use This Skill
- Core Workflow
- Reference Guide
- Safety Checklist
- Output Templates
- Concrete Example: Pod Failure Experiment (Litmus Chaos)
- Step 1 — Define steady state and apply the experiment
- Step 2 — Create and apply a Litmus ChaosEngine manifest
- Step 3 — Monitor during the experiment
- Step 4 — Rollback / abort if steady state is violated
- Concrete Example: Network Latency with toxiproxy
- Concrete Example: Chaos Monkey (Spinnaker / standalone)
