| All skills, any agent | npx skills add Donchitos/Claude-Code-Game-Studios |
|---|---|
| One skill | npx skills add Donchitos/Claude-Code-Game-Studios --skill adopt |
| Only for Claude Code | npx skills add Donchitos/Claude-Code-Game-Studios -a claude-code, or copy a skill folder to ~/.claude/skills/ (all projects) or .claude/skills/ (one project) |
npx skills is the open-source skills CLI; it asks which agents to install for. Skills can include scripts that your agent will run: read a skill before installing it, as you would any code.
