# README Generator

I'll analyze your project and generate a comprehensive README file with all essential sections.

**Features:**
- Auto-detect tech stack and dependencies
- Generate badges for build status, coverage, version
- Include code examples from actual code
- Create installation and usage instructions
- Add API documentation section
- Integration with existing `/docs` skill


## Phase 1: Project Analysis

First, let me analyze your project structure:

```bash
#!/bin/bash
# Analyze project for README generation

echo "=== Analyzing Project Structure ==="
echo ""

# Detect project type and language
detect_project_type() {
    if [ -f "package.json" ]; then
        echo "nodejs"
    elif [ -f "pyproject.toml" ] || [ -f "setup.py" ]; then
        echo "python"
    elif [ -f "go.mod" ]; then
        echo "go"
    elif [ -f "Cargo.toml" ]; then
        echo "rust"
    elif [ -f "pom.xml" ] || [ -f "build.gradle" ]; then
        echo "java"
    elif [ -f "composer.json" ]; then
        echo "php"
    else
        echo "unknown"
    fi
}

PROJECT_TYPE=$(detect_project_type)

if [ "$PROJECT_TYPE" = "unknown" ]; then
    echo "❌ Could not detect project type"
    echo ""
    echo "Supported project types:"
    echo "  - Node.js (package.json)"
    echo "  - Python (pyproject.toml, setup.py)"
    echo "  - Go (go.mod)"
    echo "  - Rust (Cargo.toml)"
    echo "  - Java (pom.xml, build.gradle)"
    echo "  - PHP (composer.json)"
    exit 1
fi

echo "✓ Detected project type: $PROJECT_TYPE"

# Extract project metadata
extract_metadata() {
    case $PROJECT_TYPE in
        nodejs)
            PROJECT_NAME=$(grep -m1 "\"name\"" package.json | sed 's/.*"name": "\(.*\)".*/\1/')

## Phase 3: Add Code Examples from Project

I'll scan your actual code to include real examples:

```bash
echo ""
echo "=== Extracting Code Examples ==="
echo ""

# Find main entry point
find_entry_point() {
    case $PROJECT_TYPE in
        nodejs)
            if [ -f "src/index.ts" ]; then
                echo "src/index.ts"
            elif [ -f "src/index.js" ]; then
                echo "src/index.js"
            elif [ -f "index.js" ]; then
                echo "index.js"
            fi
            ;;
        python)
            if [ -f "src/main.py" ]; then
                echo "src/main.py"
            elif [ -f "__main__.py" ]; then
                echo "__main__.py"
            fi
            ;;
    esac
}

ENTRY_POINT=$(find_entry_point)

if [ -n "$ENTRY_POINT" ]; then
    echo "✓ Found entry point: $ENTRY_POINT"
    echo "  Extracting example code..."

    # Extract exports or main functions
    # This would be processed to create actual examples
fi

# Find test files for usage examples
find tests -name "*.test.ts" -o -name "*.test.js" -o -name "test_*.py" \
    2>/dev/null | head -5 | while read test_file; do
    echo "  Found test: $test_file"
done
```

## Phase 4: Generate Badges

```bash
echo ""
echo "=== Generating Badges ==="
echo ""

generate_badges() {
    # Detect repository URL
    REPO_URL=$(git config --get remote.origin.url 2>/dev/null | sed 's/\.git$//')

    if [ -n "$REPO_URL" ]; then
        # Extract GitHub user and repo
        GITHUB_USER=$(echo $REPO_URL | sed 's/.*github.com[:/]\([^/]*\).*/\1/')
        REPO_NAME=$(echo $REPO_URL | sed 's/.*\/\([^/]*\)$/\1/')

        echo "Repository: $GITHUB_USER/$REPO_NAME"
        echo ""
        echo "Available badges:"
        echo "[![Build Status](https://github.com/$GITHUB_USER/$REPO_NAME/workflows/CI/badge.svg)](https://github.com/$GITHUB_USER/$REPO_NAME/actions)"

        echo "[![License](https://img.shields.io/badge/license-MIT-blue.svg)](LICENSE)"
    fi
}

generate_badges
```

## Phase 5: Enhance with Project-Specific Details

I'll customize the README based on detected features:

```bash
echo ""
echo "=== Customizing README ==="
echo ""

# Add framework-specific sections
add_framework_sections() {
    for tech in "${TECH_STACK[@]}"; do
        case $tech in
            "React"|"Next.js"|"Vue.js")
                echo "Adding frontend development section..."
                # Add component documentation
                ;;
            "Express"|"FastAPI"|"NestJS")
                echo "Adding API endpoint documentation..."
                # Add API routes documentation
                ;;
        esac
    done
}

add_framework_sections

# Add deployment section if CI/CD detected
if [ -d ".github/workflows" ] || [ -f ".gitlab-ci.yml" ]; then
    echo "Adding deployment documentation..."
    cat >> README.md << 'EOF'

## Deployment

### Automated Deployment

This project uses CI/CD for automated deployment:

```bash
# Push to main branch triggers deployment
git push origin main
```

### Manual Deployment

```bash
# Build production bundle
npm run build

# Deploy to production
npm run deploy
```

EOF
fi

echo "✓ README customization complete"
```

## Best Practices

**README Quality:**
- Keep it concise but comprehensive
- Include working code examples
- Add badges for quick status overview
- Use screenshots for visual features
- Keep installation steps simple
- Document all prerequisites

**Content Organization:**
- Table of contents for long READMEs
- Progressive disclosure (basic to advanced)
- Separate complex docs into linked files
- Use collapsible sections for optional info
- Keep examples up-to-date with code

**Maintenance:**
- Regenerate after major changes
- Keep version numbers current
- Update badges URLs
- Validate all links periodically
- Review examples for accuracy

**Integration Points:**
- `/docs` - Generate detailed documentation
- `/api-docs-generate` - API reference docs
- `/contributing` - Assess contribution readiness

## What I'll Actually Do

1. **Analyze project** - Detect type, dependencies, structure
2. **Extract metadata** - Name, version, description
3. **Identify tech stack** - Frameworks, tools, languages
4. **Generate structure** - Complete README template
5. **Add code examples** - Real examples from your code
6. **Include badges** - Build, coverage, version badges
7. **Customize sections** - Framework-specific content

**Important:** I will NEVER:
- Overwrite README without backup
- Add placeholder content without indication
- Include generic examples when real code exists
- Add AI attribution to the README

All generated READMEs are based on your actual project code and structure, ready for immediate use.

**Credits:** README patterns based on best practices from popular open-source projects, GitHub's README guidelines, and documentation standards from frameworks like Next.js, FastAPI, and Rust projects.

## Token Optimization

**Expected range**: 500–2,000 tokens (initial), 100 tokens (README current)

**Caching**: Caches project structure in `.claude/cache/readme-generate/project-structure.json` for 7 days.

**Early exit**: Returns immediately if the existing README is comprehensive and up-to-date.

**Patterns used**: Grep-before-Read, early exit, template-based generation, caching
