+# Scobleclaw Laptop Config
+
+Nix flake that reproduces MacBook software capabilities on an x86\_64 NixOS laptop.
+
+## What it installs
+
+| Tool | Purpose | Source |
+|------|---------|--------|
+| **pi** | Coding agent (TUI) | `sscoble/pi-mono` (Forgejo mirror of `badlogic/pi-mono`) |
+| **qmd** | Vault search | `@tobilu/qmd` (npm, wrapped via bunx) |
+| **git** | Version control | nixpkgs |
+| **nodejs** | JavaScript runtime | nixpkgs |
+| **bun** | Fast JS runtime + bundler | nixpkgs |
+| **zsh** | Shell (+ oh-my-zsh, autosuggestions, syntax highlighting) | nixpkgs |
+| **python3 + uv** | Python tooling | nixpkgs |
+| **docker** | Containers | nixpkgs |
+| **tailscale** | Mesh VPN | nixpkgs |
+| **ripgrep, fd, jq, bat, eza, delta** | Modern CLI tools | nixpkgs |
+| **tmux** | Terminal multiplexer | nixpkgs |
+| **nerd fonts** | JetBrains Mono, Fira Code | nixpkgs |
+
+## First-time setup (new laptop)
+
+```bash
+# 1. Install NixOS (minimal ISO)
+# 2. Clone this repo
+git clone https://os.scoble.me/forgejo/sscoble/laptop-config.git ~/laptop-config
+
+# 3. First build (this will fail — copy the npmDepsHash from error output)
+nix build ~/laptop-config#pi-coding-agent
+
+# 4. Edit flake.nix: set npmDepsHash to the value from step 3
+
+# 5. Rebuild system
+sudo nixos-rebuild switch --flake ~/laptop-config#laptop
+
+# 6. Restore personal configs
+# Copy from backup:
+#   ~/.pi/agent/SYSTEM.md
+#   ~/.pi/agent/models.json
+#   ~/.pi/agent/mcp.json
+#   ~/.pi/agent/settings.json
+#   ~/.ssh/id_ed25519
+```
+
+## Updating pi
+
+The pi-mono repo is mirrored from upstream and syncs every 24h.
+
+```bash
+# Force a mirror sync (on n97-mini)
+ssh n97-mini 'sudo -u forgejo forgejo admin repo sync --config /var/lib/forgejo/custom/conf/app.ini sscoble/pi-mono'
+```
+
+## Repo structure
+
+```
+laptop-config/
+├── flake.nix           # Main entry: overlay, nixosConfig, devShell
+├── modules/
+│   └── laptop.nix      # NixOS system module (packages, shell, fonts, SSH)
+├── home/
+│   └── sscoble.nix     # home-manager user config (git, tools, pi dirs)
+└── README.md
+```
+
+## Forgejo Actions
+
+An action keeps pi up to date — when upstream `badlogic/pi-mono` releases a new tag, the Forgejo mirror picks it up automatically. A scheduled workflow in this repo checks for tag drift daily.
