This plugin adds XMPP/Jabber, the open federated chat protocol, as a gateway platform for Hermes Agent by registering it through the documented ctx.register_platform extension point. It packages work already submitted as pull requests to the upstream Hermes Agent project as a standalone, installable plugin, so self-hosters who want XMPP support today do not have to wait for the core pull requests to be reviewed and merged; the README credits the two upstream PR authors by name and keeps a full attribution note. Feature coverage is broad: one-to-one chats and multi-user chat (MUC) group rooms, mandatory STARTTLS encryption to the XMPP server, typing indicators, HTTP file upload for media and files, structured data forms (for example to clarify a prompt), ad-hoc commands, rich message markup (bold, code, lists), threaded message replies, message reactions (used to show processing status with emoji), and stateless file sharing for voice messages. Optional OMEMO end-to-end encryption is supported for 1:1 chats when the slixmpp-omemo dependency is installed, so the XMPP server itself cannot read message content in that mode; MUC OMEMO support additionally depends on the other participants' clients and devices. The plugin also wires up Hermes' cron scheduling and send_message delivery through a standalone sender hook, so scheduled tasks can message out over XMPP the same way they do over other channels. Installation is a manual git clone into the active Hermes profile's plugins directory followed by a pip install of its requirements into the same Python environment Hermes uses, then enabling it in Hermes config and restarting the gateway; connection details are supplied through environment variables in the profile's .env file.
