# Open Source Best Practices

This skill guides you through preparing your GitHub project for sustainable open source release.

## How to Use This Skill

1. **See the full workflow** in [AGENTS.md](AGENTS.md) - the complete phases and checklist
2. **Reference detailed guides** in [references/](references/) folder:
   - File requirements and structure
   - License selection decision tree
   - Security scanning and git history cleaning
   - Governance framework
   - Maintainer expectations
   - GitHub Sponsors setup
   - Template examples

## Quick Overview

The workflow has 8 phases (do them in order; Phase 1 isn't optional):

1. **Security First** - Clean your git history using Git History Cleaner
2. **Legal & Ownership** - Choose license, verify ownership, clarify admin rights
3. **Community Foundations** - Add Code of Conduct, governance, decision-making
4. **Documentation & Onboarding** - README, CONTRIBUTING, issue/PR templates
5. **Setup Files & Infrastructure** - .gitignore, CI/CD, protected branches
6. **Maintainer Expectations** - Define roles, SLAs, communication
7. **Security & Vulnerability Reporting** - SECURITY.md, vulnerability process
8. **Funding & Sustainability** - GitHub Sponsors (optional but recommended)

## Get Started

When a user asks about open sourcing their project, begin by asking:
- **"What does your project do?"** - Understand scope
- **"Who's the audience?"** - Know your users
- **"Is your git history clean?"** - Check for secrets first

Then guide them through the phases using the full [AGENTS.md](AGENTS.md) workflow.
