A curated collection of workflow patterns with clean, copy-paste code examples for real use cases.

• Durable Agent — Replace a stateless AI agent with one that survives crashes and retries tool calls
• Human-in-the-Loop — Pause an agent for human approval, then resume based on the decision
• Agent Cancellation — Stop a running agent immediately via run.cancel() or gracefully via a hook + Promise.race

• Sequential & Parallel Execution — Compose steps with await, Promise.all, and Promise.race against durable sleeps and webhooks
• Workflow Composition — Call workflows from other workflows by direct await or background spawn via start()
• Saga — Coordinate multi-step transactions with automatic rollback when a step fails
• Batching — Process large collections in parallel batches with failure isolation
• Rate Limiting — Handle 429 responses and transient failures with RetryableError and backoff
• Scheduling — Use durable sleep to schedule actions minutes, hours, or weeks ahead
• Timeouts — Add deadlines to slow steps, hooks, and webhooks by racing them against a durable sleep
• Idempotency — Ensure side effects happen exactly once, even when steps retry
• Webhooks — Receive HTTP callbacks from external services and process them durably

• AI SDK — Use streamText() directly inside a workflow for lower-level control over model calls and tool execution
• Chat SDK — Build durable chat sessions with workflow persistence and AI SDK chat primitives
• Sandbox — Orchestrate Vercel Sandbox lifecycle inside durable workflows

• Child Workflows — Spawn and orchestrate child workflows from a parent
• Distributed Abort Controller — Build a cross-process abort controller using workflow streams and hooks
• Upgrading Workflows — Identify a clean upgrade point in a long-running workflow and spawn a fresh run on the latest deployment carrying state forward
• Serializable Steps — Wrap non-serializable third-party objects so they cross the workflow boundary
• Publishing Libraries — Ship npm packages that export reusable workflow functions
