# Setup CDK Templates

## Overview

Project context templates for Claude Code. Detects project type and generates appropriate CLAUDE.md files, `.claude/` directory structures, and custom commands.

## When to Use

- Creating CLAUDE.md for new or existing projects
- Setting up `.claude/` directory with commands/hooks
- User asks about Claude context optimization
- Part of `setup-claude-dev-kit` bundle

## Quick Reference

| Component | Location |
|-----------|----------|
| CLAUDE.md | Project root |
| Commands | `.claude/commands/` |
| Hooks | `.claude/hooks/` |
| Local settings | `.claude/settings.local.json` |

## Project Type Detection

Run these checks to detect project type:

```bash
detect_project_type() {
  if [ -f "package.json" ]; then
    if grep -q '"next"' package.json; then
      echo "web-app-next"
    elif grep -q '"react"' package.json; then
      echo "web-app-react"
    elif grep -q '"vue"' package.json; then
      echo "web-app-vue"
    elif grep -q '"express"' package.json || grep -q '"fastify"' package.json; then
      echo "api-node"
    elif grep -q '"bin"' package.json; then
      echo "cli-node"
    else
      echo "library-node"
    fi
  elif [ -f "requirements.txt" ] || [ -f "pyproject.toml" ]; then
    if [ -f "manage.py" ]; then
      echo "web-app-django"
    elif grep -qE "fastapi|flask" requirements.txt 2>/dev/null; then
      echo "api-python"
    elif [ -d "src" ] && [ -f "pyproject.toml" ]; then
      echo "library-python"
    else
      echo "cli-python"
    fi
  elif [ -f "go.mod" ]; then
    echo "go"
  elif [ -f "Cargo.toml" ]; then
    echo "rust"
  elif [ -f "pnpm-workspace.yaml" ] || [ -f "lerna.json" ] || [ -d "packages" ]; then
    echo "monorepo"
  else
    echo "generic"
  fi
}
```

## Installation Steps

### 1. Detect Project Type

```bash
PROJECT_TYPE=$(detect_project_type)
echo "Detected: $PROJECT_TYPE"
```

### 2. Create CLAUDE.md

Use the appropriate template below based on detected type.

### 3. Create .claude/ Directory

```bash
mkdir -p .claude/commands
mkdir -p .claude/hooks
```

### 4. Add Standard Commands

Create `.claude/commands/test.md`:
```markdown
Run all tests and report results. If tests fail, analyze the failure and suggest fixes.
```

Create `.claude/commands/review.md`:
```markdown
Review the recent changes for:
- Code quality and best practices
- Potential bugs or edge cases
- Performance implications
- Security concerns

Provide specific, actionable feedback.
```

### 5. Verify Setup

```bash
[ -f CLAUDE.md ] && echo "CLAUDE.md created"
[ -d .claude/commands ] && echo "Commands directory ready"
```
