- Auto-installer for Crush, Claude Code, BMAD, Starship, runtimes
- Background update daemon with hourly checks
- LSP auto-config for 16 language servers
- MCP auto-config for 12 servers (deployed to Crush + Claude Code)
- Skills system with 5 built-ins + AI-powered generation
- Crush/Claude Code proxy for unified control
- HTML preview server for visual outputs
- First-time setup wizard with interactive profiling
- Cross-platform: Linux (primary), macOS, Windows, WSL
