+## 🎓 Self-Improvement
+
+After completing complex tasks, evaluate if extractable knowledge emerged:
+
+**Log to `.learnings/` when:**
+- Non-obvious solution discovered through investigation
+- Workaround for unexpected behavior found
+- Project-specific pattern learned
+- Error required debugging to resolve
+- User corrected you ("Actually...", "No, that's wrong...")
+- Better approach discovered for a recurring task
+
+**Format:** Use the self-improvement skill format (see `skills/self-improving-agent/SKILL.md`)
+
+**High-value learnings:** If recurring or broadly applicable → promote to TOOLS.md, AGENTS.md, or extract as a new skill.
+
+**Don't overthink it:** Quick fix for a typo? Skip it. Spent 10 minutes debugging a cron config? Log it.
