Setup

Requirements, wiring steps, and what this pattern adds to your project.

Getting started

Pick how you want to pull this pattern in. Then wire env vars and routes the same way.

  1. 1

    Download → Next.js app

    Use Download → Next.js app in the preview toolbar. You get a zip scaffold (Pro downloads rewrite preview `/view/.../api/*` paths to `/api/*` automatically).

  2. 2

    Extract the zip and install dependencies

    Unzip the archive, then run `pnpm install` (or npm / yarn) in the project folder.

  3. 3

    Fill .env.local

    The download includes .env.local placeholders when needed. Add real values for: OPENAI_API_KEY.

  4. 4

    Customize the agent and tool files

    Adapt prompts, tools, and stop conditions in the generated project for your product.

  5. 5

    Run the app and open the pattern route

    Run `pnpm dev`, open the setup/checklist page if present, then navigate to the generated pattern route and verify responses.
