Use in another flake (overlay)

{
  inputs = {
    nixpkgs.url = "github:nixos/nixpkgs/nixpkgs-unstable";
    agentix.url = "github:luizribeiro/agentix";
  };

  outputs = { self, nixpkgs, agentix }:
    let
      system = "x86_64-linux";
      pkgs = import nixpkgs {
        inherit system;
        config.allowUnfree = true;
        overlays = [ agentix.overlays.default ];
      };
    in {
      devShells.${system}.default = pkgs.mkShell {
        packages = with pkgs; [
          codex-cli
          claude-code
          gemini-cli
