Claude Code - Skills Setup

Claude Code is Anthropic’s official CLI for Claude. It can be extended with skills — reusable slash commands that give Claude structured workflows for common tasks like debugging, testing, code review, and more.

Installing Skills

Skills are installed via npx skills. The -g flag installs them globally (available in all projects) and -y auto-confirms.
