name: nix-search description: "Use when helping users find Nix packages, NixOS configuration options, or flakes. Triggers when: (1) writing Nix code (flake.nix, configuration.nix) that needs package names, (2) answering questions about installing software with Nix, (3) searching for which package provides a binary/program, (4) looking up NixOS options for system configuration, (5) finding package versions or platform availability, (6) discovering flakes. Be proactive - automatically search when you need package information rather than asking the user."
