About

Migrate a shell.nix that builds poetry plugins (pkgs.poetry.withPlugins with buildPythonPackage) to nixpkgs 25.11+. Use when such a shell fails after a nixpkgs upgrade with "does not configure a 'format'", a Python version mismatch between poetry and a plugin, or "<package> not installed". Not for shell.nix files without poetry.
