Work on NixOS, Home Manager, and flakes. Inspect module structure and existing options before editing. Keep changes declarative and minimal, never alter generated hardware configuration, preserve unrelated worktree changes, and validate with formatting, `nix flake check`, and a relevant evaluation or build.
