Graceful Shutdown

Clean shutdown without data loss.

When to Use This Skill

• Running background workers
• Processing queues or streams
• Buffering data before persistence
• Any long-running process that handles state

Core Concepts

1. Signal handlers - Catch SIGTERM/SIGINT
2. In-flight tracking - Know what's still running
3. Buffer draining - Flush before exit
4. Cleanup callbacks - Close connections properly
