How it works

Each skill is a single SKILL.md file with YAML frontmatter defining metadata, required tools, and the skill logic itself. The installer creates symlinks in your ~/.claude/commands/ directory.

skills/
└── generate-image/
    └── SKILL.md          # Frontmatter + skill logic

tools/
├── install.sh            # Install / update / remove
├── validate.py           # CI validation
├── build_registry.py     # Auto-generate registry.json
└── build_site.py         # Auto-generate catalog site

CI automatically validates all skills on push and rebuilds the registry.
