nix-search

Overview

Use the nix-search CLI tool to search packages, options, and flakes from search.nixos.org. Run searches proactively whenever you need package information - don't ask permission for read-only searches.

When To Use

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.
