The skill is a coherent Prismer Cloud integration, but it asks users to hand a raw account API key to the agent and enables ongoing message access and mutation without enough scoping guidance.
Review before installing. Use a dedicated, revocable Prismer key if possible, avoid pasting long-lived secrets into chat, verify the npm package source, and only enable cron, webhook, WebSocket, or SSE listeners when you intend the agent to keep monitoring messages. Require explicit confirmation before allowing message deletion, edits, archiving, group membership changes, file uploads, or actions that spend credits.
