A self-contained, data-driven package registry for turnkey. Version metadata lives in JSON data files — Nix code reads this data to build derivations automatically. Adding a new version means adding a JSON entry, not editing Nix code.
Toolbox provides versioned, reproducible builds of curated development tools across Linux (x64/arm64) and macOS (x64/arm64), plus toolchain meta-packages that bundle related tools together.

# Build a specific version
nix build .#go.1_26_0
# Build the default version
nix build .#beads.default
# Build a toolchain meta-package
nix build .#rust-toolchain.default
# Run a tool directly
nix run .#jq.default -- --version# In turnkey's flake.nix:
inputs.toolbox.url = "github:firefly-engineering/toolbox";
# In registryExtensions:
registryExtensions = {
go = inputs.toolbox.registry.${system}.go;
beads = inputs.toolbox.registry.${system}.beads;
};Skill-bundle packages (e.g. mattpocock-skills) are Claude Code plugin directories, wired into the home-manager claude-code module one of two ways:
# flake input
inputs.toolbox.url = "github:firefly-engineering/toolbox";
# in your home-manager configuration
{ inputs, pkgs, ... }:
let toolbox = inputs.toolbox.packages.${pkgs.system};
in {
programs.claude-code = {
enable = true;
# As a plugin — the bundle's plugin.json drives which skills load:
plugins = [ toolbox.mattpocock-skills ];
# …OR as a flat skills directory (mutually exclusive with the plugin above):
# skills = "${toolbox.mattpocock-skills.skills}";
};
}Use one route, not both. The plugins route needs Claude Code ≥ 2.1.76 (≥ 2.1.157 for persistent personal plugins); the skills route has no version floor. Both need a home-manager recent enough to expose programs.claude-code.skills / .plugins. Bundles are filtered to upstream's .claude-plugin/plugin.json, so only the curated skills are installed.
