Xcode Skills

Agent skills bundled with Xcode 27 beta 5, packaged as a Claude Code plugin so you can use them outside Xcode.

Install

Any agent — npx skills

Works for Codex, Cursor, Cline, Amp, Claude Code and ~70 more. Project scope by default, -g for global:

npx skills add artemnovichkov/xcode-skills          # pick interactively
npx skills add artemnovichkov/xcode-skills --all -g # install all, globally

Installs to .agents/skills/, then links into each detected agent's own directory.

Claude Code plugin

/plugin marketplace add artemnovichkov/xcode-skills
/plugin install xcode-skills@xcode-skills

Manual

git clone https://github.com/artemnovichkov/xcode-skills.git
cp -R xcode-skills/skills/* ~/.agents/skills/   # Codex, and most other agents
cp -R xcode-skills/skills/* ~/.claude/skills/   # Claude Code

In Codex run /skills or type $ to invoke one explicitly; otherwise they trigger on description match.
