Error Recovery Patterns Skill

What to do when things break.

Recovery Hierarchy

Prevent → Detect → Contain → Recover → Learn

Retry Rules

Retry with Backoff

const delay = baseDelay * Math.pow(2, attempt - 1);
const jitter = Math.random() * 0.3 * delay;
await sleep(delay + jitter);

Circuit Breaker States

CLOSED → (failures > threshold) → OPEN → (timeout) → HALF-OPEN → (success) → CLOSED

Fallback Patterns

const result = await primary().catch(() => fallback());

Rollback Patterns

Error Boundaries

Contain failures to prevent cascade. Catch at component boundaries, log, show fallback UI.
