nix-flake

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.80). The flake template includes the flake input "github:nixos/nixpkgs?ref=nixos-unstable" (SKILL.md:56), which will be fetched during evaluation/verification (e.g., nix flake show, nix develop) and causes remote Nix code in nixpkgs to be executed as a required dependency.
