sumup

SUSPICIOUS. The skill's purpose broadly matches its capabilities, and the CLI install path is legitimate via official npm. The main issue is data-flow integrity: SumUp access is routed through Membrane's third-party platform and proxy instead of SumUp's official direct API, expanding trust and credential exposure beyond what a direct SumUp integration would require. This is not confirmed malware, but it is a medium security risk due to intermediary credential/data handling and unpinned CLI execution.
