cargo-mailbox-management

SUSPICIOUS. The skill is coherent with its stated purpose and uses an official same-org CLI from npm, so supply-chain risk is low-to-moderate rather than malicious. However, it grants the agent the ability to perform live outbound email sends and create recurring-cost mailbox resources, making the overall security risk medium due to autonomous real-world actions even though there is no clear credential harvesting, exfiltration, or deceptive routing.
