2. Create structure - .Codex/skills/skill-name/SKILL.md
3. Write frontmatter - Name, description, version, category
4. Add content - Overview, Instructions, Examples, Best Practices
5. Test - Verify skill triggers correctly

# Create skill directory
mkdir -p .Codex/skills/my-new-skill

# Create SKILL.md with template
cat > .Codex/skills/my-new-skill/SKILL.md << 'EOF'
