nix-flake-update

Quick Review

Well-structured skill with clear step-by-step workflow for updating Nix flake inputs. The description adequately covers when to invoke the skill, and the workflow provides concrete commands and decision logic. The skill automates a multi-step process (update, switch, verify, commit) with good guardrails. Novelty is moderate - while it sequences several commands and handles conditional logic, a CLI agent could perform these steps with moderate token cost. Strong on taskKnowledge with explicit commands and error handling guidance. Structure is clean and concise for the scope.
