New Project

New Project

Scaffold and bootstrap a new full-stack project. This skill is both the project creator and the foundation for how the project is planned and tracked — using GitHub issues as the planning database.

Input Handling

• Argument required: project name (kebab-case), e.g. /new-project my-app
• Optionally followed by a description: /new-project my-app "A tool that does X"
• If no argument, ask the user for project name and description

Your Task

1. Gather Information

Ask the user using AskUserQuestion:

• Project description (if not provided as argument)
• Backend stack: Python (FastAPI) or Node.js (NestJS)
• Scalingo region: osc-fr1 (default) or osc-secnum-fr1
• GitHub visibility: Public or private

2. Create Project Structure

~/dev/<project-name>/
├── api/                        # Backend
├── web/                        # Next.js frontend
├── docs/                       # Product documentation (empty)
├── CLAUDE.md                   # Project instructions for Claude Code
├── PLAN.md                     # Agent team workflow
└── README.md

3. Backend Setup (api/)

If Python (FastAPI):

Scaffold a minimal FastAPI app with:

• uv as package manager (pyproject.toml, uv.lock)
• Python 3.12 (.python-version)
• Procfile for Scalingo: web: PYTHONPATH=. python -m uvicorn api.main:app --host 0.0.0.0 --port $PORT
• Minimal FastAPI app entry point with a /health endpoint
• Dev tooling: ruff (linter/formatter), ty (type checker), pytest
• Standard .gitignore for Python

If Node.js (NestJS):

Scaffold a minimal NestJS app with:

• pnpm as package manager
• Procfile for Scalingo: web: node dist/main.js
• Minimal NestJS app with a /health endpoint
• Dev tooling: eslint, prettier
• Standard .gitignore for Node

4. Frontend Setup (web/)

Scaffold a Next.js 16 app with:

• pnpm as package manager
• TypeScript, Tailwind CSS 4, shadcn/ui
• OpenNext.js + Cloudflare Workers adapter (wrangler.toml, open-next.config.ts)
• Dev tooling: eslint, prettier
• Scripts: dev, build, preview (opennextjs-cloudflare), deploy (opennextjs-cloudflare)
• .env.local with NEXT_PUBLIC_API_URL=http://localhost:8000/api
• .env.production with NEXT_PUBLIC_API_URL=https://<project-name>-api.<region>.scalingo.io/api
• Minimal API client in src/lib/api.ts using NEXT_PUBLIC_API_URL
• Standard .gitignore for Next.js + Cloudflare

5. Root Files

• CLAUDE.md: Project-level instructions including:
  • Project overview and tech stack
  • How to run backend and frontend locally
  • Deployment targets (Scalingo for api/, Cloudflare Pages for web/)
  • Lint/test commands for each stack
• README.md: Project title, description, tech stack table, quick start commands
• PLAN.md: Agent team workflow with 4 phases:
  1. Discovery (product + devils-advocate)
  2. Design (product + devils-advocate)
  3. Build (backend-dev + frontend-dev, supervised by devils-advocate)
  4. Validate (devils-advocate)

Adapt roles and deliverables to the specific project.

6. Initialize Git and GitHub

1. git init
2. git add -A && git commit -m "feat: scaffold project structure"
3. gh repo create <project-name> --<visibility> --source . --push

7. Plan Using GitHub Issues

Use GitHub issues as the planning database. Create an initial set of issues based on the PLAN.md phases using gh issue create. The agent should document its plan, decisions, and progress as GitHub issues — not just at project creation but as an ongoing practice. Issues should be created and updated as the project evolves.

8. Install Dependencies

Run in parallel:

• Backend: uv sync (Python) or pnpm install (Node)
• Frontend: pnpm install

9. Final Report

Print a summary with project location, GitHub repo URL, created issue URLs, and quick start commands.

Guidelines

DO:

• Keep the scaffold minimal - just enough to run and deploy
• Use modern tooling: uv/ruff/ty (Python), pnpm/eslint/prettier (Node/TS)
• Create a CLAUDE.md so Claude Code understands the project from the start
• Use GitHub issues as the single source of truth for planning
• Create the docs/ directory (empty, ready for specs)

DON'T:

• Don't add business logic - just the bare scaffold
• Don't deploy anything - just set up the structure

Example Usage

/new-project my-app
/new-project my-app "A marketplace for vintage furniture"
