fail-fast
✓Use when handling errors. Use when tempted to catch and swallow exceptions. Use when returning default values to hide failures.
Installation
SKILL.md
Don't hide errors with try/catch that returns defaults. Don't let invalid state propagate. Fail at the point of failure, not three layers later with corrupted data.
| Hidden bugs | Errors become "it didn't work" | | Lost context | Stack trace shows catch, not cause | | Corrupted state | Invalid data propagates | | Debugging nightmare | Where did it actually fail? | | Silent data loss | Operations fail but app continues |
"The App Shouldn't Crash" Pressure: "Users will see errors if we throw"
