Reproducible everything. nix build and walk away.
The four Nix repos are layered, not parallel. nix-darwin sits at the top and orchestrates the macOS system. nix-home defines the user environment via home-manager. nix-ai packages every AI coding tool — Claude, Gemini, Copilot, MLX, MCP servers. nix-devenv provides reusable project-level dev shells.
Ecosystem
Package placement
The boundary between system, user, and project is intentional:environment.systemPackages(nix-darwin) — core bootstrap, macOS-only tools, GUI appshome.packages(nix-home) — user dev tools, linters, CLIs that follow$HOME- AI packages (nix-ai) — Claude, Gemini, Copilot, MLX, MCP servers
- Project dev shells (nix-devenv) — language- or stack-specific tooling that should not pollute the global PATH
programs.* declarations follow the same boundary; home-manager merges both layers cleanly.
Repos in this section
| Repo | What it does |
|---|---|
| nix-darwin | macOS system config. Imports nix-ai and nix-home. The top-level entry point. |
| nix-ai | Every AI coding tool, packaged. Claude Code, Gemini CLI, Copilot, MLX modules, MCP server configs. |
| nix-home | User dev environment via home-manager. Shell, editor, git, dev tools. |
| nix-devenv | Reusable per-project dev shells. nix flake init -t github:JacobPEvans/nix-devenv#mkshell bootstraps. |
Why four repos, not one
Each layer is independently useful.nix-devenv is consumed by every other repo in the portfolio via nix flake init. nix-ai is consumed by personal config and by team setups. Splitting them keeps the dependency graph clean and lets each layer iterate at its own pace.
