How does 'inputs' differ from 'inputs'' in this skill?

While 'inputs' refers to the raw flake inputs, 'inputs'' (inputs prime) provides those same inputs with the current system already pre-selected, removing the need for manual system interpolation.

When should I use 'flake' instead of 'perSystem'?

Use 'perSystem' for things that exist on every platform (packages, shells, checks). Use 'flake' for unique, non-system-specific outputs like NixOS or Home Manager configurations.

How can I debug flake-parts issues using Claude?

Claude can guide you through enabling debug mode in your flake and using 'nix repl' to inspect system-specific arguments, option declarations, and evaluated package sets.

What is the primary benefit of using flake-parts?

It applies the NixOS module system to flakes, allowing you to define configurations once in a 'perSystem' block and automatically generate outputs for all target architectures, drastically reducing boilerplate.

デプロイメントとDevOps

Streamlines multi-system Nix flake development by implementing the modular flake-parts framework.

概要

The Nix Flake-Parts Expert skill provides specialized guidance for using the flake-parts framework to organize and scale Nix flakes. It helps developers apply the NixOS module system to flake configurations, eliminating repetitive boilerplate for multi-system builds. By leveraging perSystem abstractions and advanced module arguments, this skill enables the creation of maintainable, modular, and highly reusable Nix infrastructure for packages, development shells, and system configurations.
