Efficiency Patterns

When to Use This Skill

Efficiency patterns optimize what your automation does and whether it needs to do it.

| Pattern | When to Use | Strategy | | --------- | ------------- | ---------- | | Idempotency | Operations may be retried | Same input = same result | | Work Avoidance | Results can be cached | Skip if already done |

Implementation

See the full implementation guide in the source documentation.

Quick Reference

| Scenario | Pattern | Reasoning | | ---------- | --------- | ----------- | | Re-running same operation | Idempotency | Same result every time | | Resource already exists | Idempotency | Create-or-update safely | | Content unchanged | Work Avoidance | Skip unnecessary work | | Build artifact cached | Work Avoidance | Reuse previous results |

Key Difference

| Aspect | Idempotency | Work Avoidance | | -------- | ------------- | ---------------- | | Goal | Safe to retry | Avoid doing work | | Mechanism | Deterministic result | Change detection | | Trade-off | Complexity vs reliability | Cache invalidation vs speed |

Idempotency makes retries safe. Work avoidance makes retries unnecessary.

Comparison

Idempotency makes retries safe. Work avoidance makes retries unnecessary.
