        mkdir -p $out/bin
        # Assuming the main executable is 'caelestia.py' or similar in the root

        chmod +x $out/bin/caelestia-cli

      # or to add them to buildInputs and ensure they are in the python path.
      # For a simpler script, just copying might be enough.
      # You may need to inspect the 'cli' repo more closely for its build instructions.
      # If it's pure shell script, 'stdenv.mkDerivation' is fine with just 'installPhase'.
      # If it's a Python project with setup.py, consider using pkgs.python3Packages.buildPythonPackage
      # or pkgs.buildPythonApplication.
