updater

The updater skill fragment is conceptually aligned with its purpose and presents a controlled surface for macOS app maintenance via external updater tooling. Primary security considerations center on the legitimacy of the Homebrew tap used for installation and how JSON outputs are logged or transmitted by an agent. No credentials or direct network exfiltration are evident within the fragment itself. Recommend validating tap trust, constraining environment where updater runs, and auditing downstream handling of JSON outputs in integrated deployments.
