Can I use this for Kubernetes infrastructure?

Yes, it specifically covers K3s infrastructure management and demonstrates how to render Helm charts and Kustomize manifests at build time using Nix.

Is this suitable for production DevOps workflows?

Yes, it focuses on production-grade patterns such as OCI image packaging for airgapped deployments and advanced NixOS module priority overrides.

How does this skill help with Nix flake management?

It provides standardized patterns for multi-repo flake composition, including how to pin inputs with 'follows' and manage outputs for systems, packages, and devShells.

Does it support Home Manager for dotfiles?

Absolutely. The skill integrates Home Manager best practices for declarative user environment management alongside core NixOS system configurations.

What common NixOS errors can this skill resolve?

It includes troubleshooting guidance for infinite recursion, missing store paths, attribute errors, and common flake synchronization issues like untracked files.
