Trigger Dev Tasks

This teaches Claude how to build production-grade background jobs with Trigger.dev's SDK. It's opinionated about the right patterns: never use Promise.all with wait calls, always export your tasks, use idempotency keys for critical operations like payments. The guidance covers the full workflow from basic task definitions with Zod validation to batch triggering, debouncing, and machine presets. What's practical here is the focus on when to break workflows into subtasks versus keeping things simple with Promise.allSettled in a single task. If you're building anything with async jobs, scheduled tasks, or AI workflows that need reliable retries, this will save you from the common gotchas.
