README Generator

Style: $0 (default: standard)

Steps

1. Analyze the project:

   • Read package.json / pyproject.toml / go.mod for project metadata
   • Read existing README if present (preserve custom sections)
   • Scan directory structure for architecture insights
   • Check for existing docs (API docs, guides, ADRs)
   • Identify the tech stack from dependencies

2. Generate sections based on style:

Minimal

• Project name + one-line description
• Quick start (install + run)
• License

Standard (default)

• Project name + description
• Tech stack badges
• Prerequisites
• Installation
• Development (run, test, lint)
• Project structure (key directories only)
• Environment variables (from .env.example)
• Deployment
• Contributing
• License

Detailed

• Everything in Standard, plus:
• Architecture overview
• API documentation summary
• Database schema overview
• CI/CD pipeline description
• Troubleshooting
• Changelog or link to releases

3. Generate environment variable documentation:

   • Read .env.example if it exists
   • Document each variable with description, required/optional, example value
   • Group by category (database, auth, external services)

4. Write the README:

Constraints

• Don't invent features — only document what exists in the code
• Keep language concise and scannable
• Use tables for structured data (env vars, scripts)
• Include actual commands, not placeholders
• If a section doesn't apply, skip it — don't add empty sections
