Error Handling Patterns
When to Use This Skill
Error handling is about when and how your automation responds to problems.
| Pattern | When to Use | Strategy |
|---|---|---|
| Fail Fast | Invalid input, missing config | Stop immediately, report clearly |
| Prerequisite Checks | Complex preconditions | Validate all upfront before work |
| Graceful Degradation | Fallbacks exist | Degrade to safer state, continue |
Implementation
See the full implementation guide in the source documentation.

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.
