Systematic Debugging

Evidence-based investigation -> root cause -> verified fix.

Steps

1. Load the outfitter:maintain-tasks skill for stage tracking
2. Collect evidence (reproduce, gather symptoms)
3. Isolate variables (narrow scope)
4. Formulate and test hypotheses
5. Implement fix with failing test first
6. Verify fix resolves the issue

For formal incident investigation requiring RCA documentation, use find-root-causes skill instead (it loads this skill and adds formal RCA methodology).
