+description: Systematic debugging: reproduce, isolate, form hypotheses, instrument, fix, and add regression tests. Use when troubleshooting errors, failing tests, or unexpected behavior.

+# Debug Skill
+
+## When to use this skill
+- runtime errors, flaky tests, wrong outputs
+- “it used to work” regressions
+- performance or timeout problems (initial triage)
+
+## Debug workflow (do not skip steps)
+1. **Reproduce**
+   - Capture exact error, inputs, environment, command.
+2. **Minimize**
+   - Reduce to smallest repro (one file, one function, smallest dataset).
+3. **Hypotheses (2–5)**
+   - Rank by likelihood.
+4. **Instrument**
+   - Add temporary logging/assertions or use existing diagnostics.
+5. **Fix**
+   - Smallest change that removes root cause.
+6. **Prevent**
+   - Add regression test or permanent guard/validation.
+7. **Verify**
+   - Run the failing case + relevant suites.
