+
+# Project Onboarding
+
+## Pre-computed Context
+
+**Project Root Files:**
+!`ls -la | head -20`
+
+**Package.json (if exists):**
+!`cat package.json 2>/dev/null | head -30 || echo "No package.json"`
+
+**README (if exists):**
+!`head -50 README.md 2>/dev/null || head -50 README 2>/dev/null || echo "No README"`
+
+**Git Info:**
+!`git remote -v 2>/dev/null | head -2 && echo "---" && git log --oneline -3 2>/dev/null || echo "Not a git repo"`
+
+---
+
+## Instructions
+
+You are onboarding to a new project. Your goal is to understand the codebase quickly.
+
+### 1. Detect Tech Stack
+
+Look for these indicators:
+
+| File | Stack |
+|------|-------|
+| `package.json` | Node.js/JavaScript |
+| `tsconfig.json` | TypeScript |
+| `pyproject.toml`, `requirements.txt` | Python |
+| `go.mod` | Go |
+| `Cargo.toml` | Rust |
+| `pom.xml`, `build.gradle` | Java |
+| `Gemfile` | Ruby |
+| `composer.json` | PHP |
+
+### 2. Identify Framework
+
+| Indicator | Framework |
+|-----------|-----------|
+| `next.config.*` | Next.js |
+| `vite.config.*` | Vite |
+| `angular.json` | Angular |
+| `vue.config.*` | Vue |
+| `remix.config.*` | Remix |
+| `astro.config.*` | Astro |
+| `django`, `settings.py` | Django |
+| `flask` | Flask |
+| `fastapi` | FastAPI |
+
+### 3. Read Key Files
+
+#### Always Read
+- `README.md` - Project overview
+- `CONTRIBUTING.md` - Development guidelines
+- `CLAUDE.md` or `.claude/rules/` - AI assistant instructions
+
+#### JavaScript/TypeScript
+- `package.json` - Dependencies and scripts
+- `tsconfig.json` - TypeScript configuration
+- `src/index.ts` or `src/main.ts` - Entry point
+
+#### Python
+- `pyproject.toml` or `setup.py` - Project config
+- `requirements.txt` - Dependencies
+- `main.py` or `app.py` - Entry point
+
+### 4. Understand Project Structure
+
+```bash
+# Show directory structure
+find . -type d -not -path '*/node_modules/*' -not -path '*/.git/*' -not -path '*/__pycache__/*' | head -30
+```
+
+Common patterns:
+- `src/` - Source code
+- `tests/` or `__tests__/` - Test files
+- `lib/` - Library code
+- `docs/` - Documentation
+- `scripts/` - Build/utility scripts
+
+### 5. Generate Summary
+
+After analysis, provide:
+
+```markdown
+## Project: <name>
+
+### Tech Stack
+- **Language**: TypeScript
+- **Framework**: Next.js 14
+- **Database**: PostgreSQL with Prisma
+- **Testing**: Jest + React Testing Library
+
+### Key Directories
+- `src/app/` - Next.js app router pages
+- `src/components/` - React components
+- `src/lib/` - Utility functions
+- `prisma/` - Database schema
+
+### Available Scripts
+- `npm run dev` - Start development server
+- `npm run build` - Build for production
+- `npm test` - Run tests
+
+### Quick Start
+1. `npm install`
+2. `cp .env.example .env`
+3. `npm run dev`
+
+### Notes
+- Uses App Router (not Pages Router)
+- Auth handled by NextAuth.js
+- State management with Zustand
+```
+

+
+## Usage
+
+When starting work on a new project:
+
+```bash
+cd /path/to/new/project
+claude
+
+# In Claude:
+/workflow:onboard
+```
+
+This gives you context to start working effectively.
