## What it does

This skill hands the agent the docs for the TypeScript/JavaScript `@upstash/workflow` SDK, which runs on QStash. It covers `serve()` for the workflow endpoint, `context.run` for steps, `context.call` for external APIs, waiting on events or webhooks, and invoking other workflows. Separate files walk through retries, failure callbacks and a DLQ, plus rate, concurrency and parallelism limits and the `Client` for triggering, cancelling and inspecting runs.

There are also sections on local development with the QStash dev server (turned on with `QSTASH_DEV=true`), realtime updates, human-in-the-loop approvals, middleware and safe migrations. Low-level REST endpoints and a troubleshooting file round it out. Think of it as a reference the agent pulls in when you ask for durable execution, a saga pattern or background jobs with checkpoints on Vercel, Next.js or Cloudflare Workers.

The package itself installs with `npm install @upstash/workflow`, and running a workflow needs a `QSTASH_TOKEN` environment variable. The client will not work without that token, so check it before asking the agent to generate trigger code.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add upstash/skills --skill upstash-workflow-js -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/upstash-workflow-js/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/upstash-workflow-js/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add upstash/skills --skill upstash-workflow-js -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/upstash-workflow-js/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add upstash/skills --skill upstash-workflow-js -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/upstash-workflow-js/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install upstash/skills upstash-workflow-js
```

2. **Manually: put the files in place**
- File: `.github/skills/upstash-workflow-js/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add upstash/skills --skill upstash-workflow-js -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/upstash/skills --path skills/upstash-workflow-js
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/upstash-workflow-js/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add upstash/skills --skill upstash-workflow-js -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/upstash/skills/tree/HEAD/skills/upstash-workflow-js/SKILL.md

## When to use it
- define a workflow endpoint with `serve()`
- split a long process into steps with `context.run`
- sleep for minutes or days without holding a function open
- set up retries, failure callbacks and a DLQ
- cap concurrency and request rate

## Example prompts
- Write a `@upstash/workflow` endpoint with three steps and an external API call via `context.call`.
- Add retries and a failure callback to a workflow that hits a payment service.
- How do I start the local QStash dev server to debug a workflow?

description: Work with the @upstash/workflow TypeScript/JavaScript SDK for durable, long-running workflows in serverless functions, multi-step processes that survive timeouts, retries, and restarts (built on QStash). Use when defining a workflow endpoint with serve(), running steps with context.run, sleeping for minutes to days without holding a function open, calling external APIs with context.call, waiting for an external event or webhook, invoking other workflows, configuring retries, failure callbacks, and a DLQ, controlling concurrency, rate, and parallelism, triggering, cancelling, or inspecting runs with the Workflow client, building AI agents and orchestrators, human-in-the-loop approvals, realtime updates, local development with the QStash dev server, adding middleware, or migrating workflows safely. Also use when the user asks for durable execution, step functions, saga or orchestration patterns, background jobs with checkpoints, or long-running tasks on Vercel, Next.js, Cloudflare Workers, or other serverless platforms.

# Upstash Workflow SDK

## Quick Start

The Upstash Workflow SDK lets you expose serverless workflow endpoints and run them reliably using QStash under the hood.

Install:

```bash
npm install @upstash/workflow
```

Define a simple workflow endpoint:

```ts
import { serve } from "@upstash/workflow";

export const { POST } = serve(async (context) => {
  await context.run("step-1", () => console.log("step 1"));
  await context.run("step-2", () => console.log("step 2"));
});
```

Trigger it from your backend:

```ts
import { Client } from "@upstash/workflow";

const client = new Client({ token: process.env.QSTASH_TOKEN! });
await client.trigger({ url: "https://your-app.com/api/workflow" });
```
