# Five Whys Root Cause Analysis

> Evidence-based root cause diagnosis using a branching five-whys investigation. Produces a likelihood-ranked list of candidate root causes — diagnosis only, never a fix. Use ONLY when the user explicitly asks to diagnose a problem or find a root cause, with phrases like "find the root cause", "diagnose this", "do a five whys check", "root cause analysis", "why is this happening", or "run a five whys". Do NOT trigger on generic mentions of errors, bugs, or fix requests.
