Your Agent Needs More Skills

Claude Code skills are powerful but non-distributable. Each user's skill directory is a local collection with no mechanism for discovery, installation, or sharing between users.

**arc is `apt install` for agentic skills.** It manages the full lifecycle — search a registry, review capabilities, install with one command, audit what's running.

arc search doc                # Find packages across all sources
arc install _DOC              # Install with capability review
arc audit                     # See your total attack surface
