    # NixOS Rules

    - This machine is NixOS. Prefer the Nix way for installing and running tools.
    - Do not suggest `apt`, `dnf`, `pacman`, `brew`, `npm -g`, `pip install`, `cargo install`, `curl | sh`, or manual installers unless explicitly asked.
    - If a repo has `flake.nix`, treat it as the source of truth for project tooling.
    - If a needed tool belongs to the project, add it to `flake.nix` or the dev shell instead of installing it another way.
    - If a repo has `flake.nix`, ensure `.envrc` contains `use flake` unless the repo intentionally uses a different setup.
    - If there is no `flake.nix` and the tool is only needed temporarily, prefer `nix shell nixpkgs#<pkg> -c <command>`.
    - For persistent tools, prefer declarative Nix configuration.
    - Prefer `direnv` or `nix develop` before deciding a tool is missing.
    - Never run `nixos-rebuild`, `nh os switch`, `nhs`, or other system switch commands unless explicitly asked.
