trigger-dev-tasks

The Trigger.dev Task Expert is an advanced coding and architectural assistant tailored for developers building durable, long-running backend workflows. It provides precise guidance on implementing task-based systems using the @trigger.dev/sdk, ensuring your background jobs are scalable, observable, and production-ready. Whether you are building complex AI agents that require chaining, state management, or human-in-the-loop approval processes, this skill ensures best practices are followed regarding reliability and performance.

• Full support for defining tasks using task and schemaTask with Zod validation for runtime type safety.

• Advanced orchestration capabilities including triggerAndWait, batchTriggerAndWait, and dependency-free subtask management.

• Fine-grained control over job execution, including idempotency keys, custom retries, exponential backoff, and concurrency rate limiting.

• Integration expertise for build-time extensions like FFmpeg, Puppeteer, and Playwright for browser-based automation and media processing.

• Configuration guidance for machine presets (micro to large), cron-based scheduling, and webhook deduplication using debouncing.

• Always prioritize the native fetch API over node-fetch to ensure runtime compatibility.

• Avoid wrapping wait and trigger calls in Promise.all to prevent runtime errors during task checkpoints.

• Use idempotency keys for all side-effecting operations to guarantee successful retries.

• Leverage logger.info and logger.error for comprehensive observability within the Trigger.dev dashboard.

• Group related logic into non-exported subtasks to maintain a clean, modular repository structure.

• Consult the provided reference architecture for best practices on handling long-running, non-terminating workflows and human-in-the-loop waitpoints.
