This skill appears to do what it advertises, but it needs review because it can control a Facebook Page using a long-lived token and its safeguards are weak.
Install only after reviewing the Facebook permissions and secret handling. Use a test or low-risk page first, store the access token through a protected secret mechanism if possible, restrict local config permissions, do not share output from the connection script, and rotate or revoke the token if it appears in logs or screenshots. Enable auto-reply only with clear authority to process Messenger messages and with human review or audit controls for outgoing posts, comments, and messages.
