swain-update

SUSPICIOUS. The skill's stated purpose matches its update behavior, and the main install path uses an official public CLI, but the overall footprint is still risky because it installs a full third-party skill bundle from a personal repo, uses wildcard selection, includes an unpinned git-clone fallback, and chains into another skill. This looks more like a high-trust updater than overt malware, but the transitive trust and local overwrite behavior make it medium-high risk.
