effect-workflow

What problem does it solve?

This Skill helps you design durable, restart-safe workflows in TypeScript so side effects run reliably, results persist across replays, and long-running steps can wait for external signals.

Core Features & Use Cases

• Durable workflow execution: Define workflows with typed payloads and deterministic idempotency so repeated executions resume instead of duplicating work.
• Atomic side effects via activities: Model external calls as activities whose results are persisted, making replay safe and predictable.
• Saga-style compensation: Add rollback logic using Workflow.withCompensation to implement compensation for distributed failures.
• External event & timers: Use DurableDeferred to wait for durable signals and DurableClock for restart-safe sleep.
• Cluster-friendly execution: Integrate with ClusterWorkflowEngine.layer for distributed durability.

Quick Start

Ask the assistant to implement a durable order-processing workflow that validates input, reserves inventory with compensation, waits for a payment confirmation signal, sleeps before shipping, and then executes shipping as an activity using Effect’s unstable workflow APIs.
