Agent Skills: dendritic-nix

Applies the Dendritic Pattern for structuring Nix flake configurations with flake-parts. Every file is a flake-parts module organized by feature (aspect), not by configuration class. Use when structuring Nix flakes, creating flake-parts modules, composing multi-host configs, organizing NixOS/home-manager/nix-darwin configuration, or sharing values across configuration classes. Triggers: nix flake structure, flake-parts modules, multi-host configs, aspect modules. Do NOT use for general Nix language questions, nixpkgs packaging, or NixOS module authoring unrelated to flake structure.
