# Build trustworthy background job processing > Queue async work with retries, dead-letters, and observability so failures surface instead of vanishing. **Track:** ⚙️ Backend Engineering · **Domain:** Caching & Queues · **Level:** intermediate · **~35 min** **Who this is for:** Backend Engineers, API Developers, Platform Engineers, Full-Stack Developers ## When to Use This Skill Queue async work with retries, dead-letters, and observability so failures surface instead of vanishing. Use it whenever a matching task appears in conversation — the agent loads these instructions on demand. ## Steps 1. Make handlers idempotent; assume at-least-once delivery 2. Set exponential backoff with jitter; cap retries at sane counts 3. Dead-letter poison messages with full context for triage 4. Separate queues by latency class and priority; prevent head-of-line blocking 5. Emit metrics: depth, age of oldest job, success rate, duration percentiles 6. Alert on oldest-job-age, not just queue depth ## Common Pitfalls - Long jobs blocking a shared queue of quick tasks - Silent retries masking a permanently failing handler ## Commands **Install with skills CLI** ```bash npx skills add aniruddhaadak80/skills --skill caching-queues-background-jobs ``` **Install globally** ```bash npx skills add aniruddhaadak80/skills --skill caching-queues-background-jobs -g ``` --- Part of [aniruddhaadak80/skills](https://github.com/aniruddhaadak80/skills) · Browse all at https://skills.sh/aniruddhaada
