Frequently Asked Questions About John Muchovej
FAQPage SchemaWhat tasks can I accomplish with jmuchovej's skills?▼
You can analyze flake.lock bumps for breakage before switching, run the full OpenSpec change lifecycle (propose, explore, apply, update, sync, archive), scaffold NixOS/Home Manager/nix-darwin modules, apply Nix naming and conditional patterns, validate Nix code with statix/deadnix, and generate conventional commit messages.
Who are these skills designed for?▼
Nix and NixOS developers managing flake-based configurations, plus engineers using OpenSpec for spec-driven change planning. They suit anyone maintaining declarative system configs, writing Nix modules, or enforcing Git branching and conventional commit standards.
How does the flake-brief skill run in practice?▼
Run it headless via `claude -p "/flake-brief"` after `just update` or any flake.lock bump. It reads flake.lock, flake.nix, and module sources, diffs watched inputs between old and new revisions using git, nix flake prefetch, and gh, then prints a transition/breakage brief to stdout.
Are these skills open source and what do they cost?▼
The seven OpenSpec skills carry an explicit MIT license at no cost. The Nix and Git skills ship without a stated license in their frontmatter. All skills are free to invoke; the only requirement is the corresponding runtime such as the openspec CLI.
What prerequisites do these skills require?▼
OpenSpec skills require the openspec CLI installed. flake-brief requires a Nix flake repository with git, nix, gh, ripgrep, and diff available, plus read access to flake.lock, flake.nix, and module sources. Nix and Git skills need only a Nix or Git project context.
