Workflow Init Agent Skill

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:

• Next.js - next dep or next.config.*
• Nuxt - nuxt dep or nuxt.config.*
• SvelteKit - @sveltejs/kit dep or svelte.config.*
• Astro - astro dep or astro.config.*
• NestJS - @nestjs/core dep or nest-cli.json
• Nitro - nitro dep or nitro.config.*
• Express - express dep
• Fastify - fastify dep
• 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/.
