Install and configure Vercel Workflow SDK before it exists in node_modules. Use when the user asks to "install workflow", "set up workflow", "add durable workflows", "configure workflow sdk", or "init workflow" for Next.js, Express, Hono, Fastify, NestJS, Nitro, Nuxt, Astro, SvelteKit, or Vite.

workflow init Initial setup of Vercel Workflow SDK before workflow is installed. Fetch the official getting started guide for the user's framework. Decision flow 0) Sanity check Read package.json . If workflow is already a dependency, tell the user to use /workflow instead (it reads versioned docs from node modules/workflow/docs/ ). Only continue if workflow is missing. 1) Determine the framework Non interactive: If the user named a framework in their prompt, use it directly. Auto detect: Inspect package.json deps and config files. Use the first match: 1. Next.js next dep or next.config. 2. Nuxt nuxt dep or nuxt.config. 3. SvelteKit @sveltejs/kit dep or svelte.config. 4. Astro astro dep or astro.config. 5. NestJS @nestjs/core dep or nest cli.json 6. Nitro nitro dep or nitro.config. 7. Express express dep 8. Fastify fastify dep 9. Hono hono dep 10. Vite vite dep (and not matched above) If no match or multiple matches, ask the user to pick. 2) Fetch and follow the getting started guide Fetch exactly one of these URLs and follow the guide step by step: Framework URL Next.js https://workflow sdk.dev/docs/getting started/next Express https://workflow sdk.dev/docs/getting started/express Hono https://workflow sdk.dev/docs/getting started/hono Fastify https://workflow sdk.dev/docs/getting started/fastify NestJS https://workflow sdk.dev/docs/getting started/nestjs Nitro https://workflow sdk.dev/docs/getting started/nitro Nuxt https://workflow sdk.dev/docs/getting started/nuxt Astro https://workflow sdk.dev/docs/getting started/astro SvelteKit https://workflow sdk.dev/docs/getting started/sveltekit Vite https://workflow sdk.dev/docs/getting started/vite Each guide covers: install deps, configure framework, create first workflow, create route handler, run + verify. 3) Verify setup Start the dev server per the guide. Trigger the example endpoint with the provided curl . Confirm logs show the workflow and steps executing. Optional: npx workflow web or npx workflow inspect runs . 4) No framework yet? If no framework exists, ask what the user wants: Web app : Next.js / Nuxt / SvelteKit / Astro API server : Express / Fastify / Hono Minimal server : Nitro or Vite Then follow the "Create Your Project" section of the chosen guide. Concept questions (pre install) If the user asks conceptual questions before installing, fetch: https://workflow sdk.dev/docs/foundations/workflows and steps https://workflow sdk.dev/cookbook Handoff When setup is complete, tell the user: Use /workflow for ongoing development it reads the versioned docs bundled in node modules/workflow/docs/ .
