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:

#!/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

Phase 5: Enhance with Project-Specific Details

# 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

# Build production bundle
npm run build

# Deploy to production
npm run deploy

EOF fi

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
