Interactive Root Cause Analysis enforcer. Guides you through the 7-step RCA protocol: Reproduce, Locate, Hypothesis, Failing Test, Fix, Verify Live, Document. Use when debugging a bug, investigating a failure, or when something unexpected happened. This skill gates each step — it won't let you skip to a fix without stating a hypothesis first. Triggers on: 'something is broken', 'debug this', 'why is this failing', 'RCA', 'root cause', or /hk-rca.
