+- ✅ Exit detection and signals
+- ✅ Response analysis pipeline
+- ✅ Circuit breaker pattern
+- ✅ Loop execution workflows
+- ✅ Edge cases and error conditions
+
+### Missing (~30% to reach 90%+)

+2. **tmux Integration Tests** - Test monitoring infrastructure
+3. **CLI Parsing Tests** - Validate argument handling
+
+### Medium Priority (Week 5)
+4. **Log Rotation** - Prevent log file bloat
+5. **Config File Support** - Enable customization
+
+### Low Priority (Week 6)
+6. **Metrics/Notifications/Backup** - Nice-to-have features
+7. **E2E Tests** - Final validation
+
+### Documentation
+8. **CI/CD Setup** - Automate testing
+9. **Testing Guide** - Onboard contributors
