type: overview

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

## Agent Patterns

- [**WorkflowAgent**](/cookbook/agent-patterns/durable-agent) — Build durable, resumable AI agents with AI SDK's WorkflowAgent
- [**Human-in-the-Loop**](/cookbook/agent-patterns/human-in-the-loop) — Pause an agent for human approval, then resume based on the decision
- [**Agent Cancellation**](/cookbook/agent-patterns/agent-cancellation) — Stop a running agent immediately via `run.cancel()` or gracefully via a hook + `Promise.race`

## Common Patterns

- [**Sequential & Parallel Execution**](/cookbook/common-patterns/sequential-and-parallel) — Compose steps with `await`, `Promise.all`, and `Promise.race` against durable sleeps and webhooks
- [**Workflow Composition**](/cookbook/common-patterns/workflow-composition) — Call workflows from other workflows by direct await or background spawn via `start()`
- [**Saga**](/cookbook/common-patterns/saga) — Coordinate multi-step transactions with automatic rollback when a step fails
- [**Batching**](/cookbook/common-patterns/batching) — Process large collections in parallel batches with failure isolation
- [**Rate Limiting**](/cookbook/common-patterns/rate-limiting) — Handle 429 responses and transient failures with RetryableError and backoff
- [**Scheduling**](/cookbook/common-patterns/scheduling) — Use durable sleep to schedule actions minutes, hours, or weeks ahead
- [**Timeouts**](/cookbook/common-patterns/timeouts) — Add deadlines to slow steps, hooks, and webhooks by racing them against a durable sleep
- [**Idempotency**](/cookbook/common-patterns/idempotency) — Ensure side effects and duplicate starts are safe to retry
- [**Webhooks**](/cookbook/common-patterns/webhooks) — Receive HTTP callbacks from external services and process them durably

## Integrations

- [**AI SDK**](/cookbook/integrations/ai-sdk) — Use streamText() directly inside a workflow for lower-level control over model calls and tool execution
- [**Chat SDK**](/cookbook/integrations/chat-sdk) — Build durable chat sessions with workflow persistence and AI SDK chat primitives
- [**Sandbox**](/cookbook/integrations/sandbox) — Orchestrate Vercel Sandbox lifecycle inside durable workflows

## Advanced

- [**Child Workflows**](/cookbook/advanced/child-workflows) — Spawn and orchestrate child workflows from a parent
- [**Distributed Abort Controller**](/cookbook/advanced/distributed-abort-controller) — Build a cross-process abort controller using workflow streams and hooks
- [**Upgrading Workflows**](/cookbook/advanced/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**](/cookbook/advanced/serializable-steps) — Wrap non-serializable third-party objects so they cross the workflow boundary
- [**Publishing Libraries**](/cookbook/advanced/publishing-libraries) — Ship npm packages that export reusable workflow functions
