sixel-email
Security checks across malware telemetry and agentic risk
Overview
This instruction-only skill appears to do what it claims: let an agent email and receive replies from one configured human operator through sixel.email.
Before installing, confirm the SIXEL_API_TOKEN is scoped only to the intended agent/operator channel, do not send secrets over plaintext email, treat inbound messages and attachments as untrusted, and run any background poller in a constrained environment with a dedicated download directory.
