pubnub

SUSPICIOUS: The skill's purpose and capabilities mostly align, and the CLI install path appears legitimate via Membrane's official npm package. The main concern is data-flow integrity: PubNub access is mediated through Membrane's proxy and account system rather than going directly to PubNub, which adds a third-party trust boundary and credential/data exposure risk. Not clearly malicious, but risk is above benign due to intermediary routing and mutable CLI invocation examples.
