Chaos Engineering Design experiments that surface real weaknesses in production systems — without becoming outages. Most "chaos engineering" attempts skip steady-state measurement, define no abort criteria, and have no blast-radius bound. This skill enforces the discipline that makes chaos experiments safe and useful. When to use - Planning a chaos experiment (what to break, where, when, how to abort) - Calculating blast radius before running the experiment - Reviewing an existing experiment plan for safety - Choosing a chaos tool (Chaos Toolkit / Chaos Mesh / Litmus / Gremlin / AWS FIS) - Wr…
