🚀 Features

System Architecture

• NixOS 25.11 with Flakes
• Disko for declarative disk partitioning
• Home Manager for user environments

Desktop Environment

• Hyprland (Wayland compositor) with extensive customization
• Catppuccin Macchiato theme throughout
• Waybar, Wofi, SwayNC for desktop utilities
• Alternative: GNOME/KDE support available

Development Stack

• Editors: Cursor, VS Code, Neovim (LazyVim), Claude Code
• Languages: Python, Node.js, Go
• Tools: Git, Direnv, FZF, Ripgrep, Bat
• Containers: Docker, Libvirt/QEMU
• Terminal: Zsh + Starship, Zellij/Tmux

Agent Tooling

• Claude Code, opencode, pi managed via Home Manager modules
• Shared skills under home/modules/agent-skills/skills/ symlink into ~/.claude/skills/ and ~/.agents/skills/ so all three agents see the same SKILL.md set
• Pi extensions auto-discovered from home/modules/pi/extensions/; locally-dropped extensions in ~/.pi/agent/extensions/ survive activations

Security & Auth

• 1Password integration
• YubiKey support (PAM U2F)
• SOPS for secret management (TBD)
• WireGuard VPN (TBD)

🛠️ Usage

Quick Commands

just update          # Update flake inputs
just switch          # Apply configuration
just build hostname  # Build specific host
just deploy host ip  # Remote deployment

Initial Setup

1. Clone repository
2. Update hardware configuration for your system
3. Run just switch hostname
4. Change default password immediately: passwd

Maintenance

• Updates: just update then just switch
• Garbage collection: Runs automatically (daily, 3-day retention)
• VM testing: just buildvm hostname
