Nix Tooling
Use Nix (flakes) to obtain programs and tools instead of apt, brew, pip install, npm -g, or other system-level package managers. Activate this skill whenever a command is not found in $PATH, whenever you need to install or obtain a CLI tool, compiler, formatter, linter, or runtime, or whenever the user mentions Nix, nixpkgs, nix run, nix develop, or flake.nix. Also activate when you're about to reach for apt-get, brew, pip install --global, npm install -g, or cargo install — use the Nix equivalent instead. This skill applies to Claude Code terminal usage.
