Quick Reference

| Scenario | Pattern | Reasoning | | ---------- | --------- | ----------- | | Missing required config | Fail Fast | Can't continue safely | | Invalid user input | Fail Fast | User error, report immediately | | Complex deployment requirements | Prerequisite Checks | Validate tools, access, state | | API timeout | Graceful Degradation | Retry or use backup | | Service unavailable | Graceful Degradation | Fall back to alternatives |

Fail fast when you can't recover. Degrade gracefully when you can.
