Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install nix-flakes-overlays-practices

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent applies a standard flake structure, avoids duplicating nixpkgs with follows, and handles unfree packages according to context. It also explains how to get the SHA256 hashes for a binary overlay.
