We run Hermes on self-hosted Rocket.Chat and gave it a project-manager profile plus access to YouTrack and our company knowledge base, then wired it into chat with an MIT platform plugin (DDP inbound / REST outbound). The team calls it HalfPM according to our company name :D

What it does on the channel:

• "where are we on project X?" → grouped ticket status + what it flags as risk
• "summary of open tickets by person" → with clickable links
• "check tomorrow if Tom updated the contract ticket; if not, DM him and report back here" → finds the ticket, schedules a cron, delivers the DM (survives a gateway restart)
• "open a ticket for Peter to order coffee" → picks the project, maps the name to a YouTrack user, sets sane defaults — all from the knowledge base

Full write-up: how the plugin, profile, thread context and cron delivery fit together — plus an honest security lesson from red-teaming a bot with real access:

Plugin's open source if you want the same setup. But you can build something simillar on slack too :)

We self-host Rocket.Chat and wanted our Hermes Agent instance to live in it instead of a separate web UI. Published the adapter as a standalone plugin, MIT:

https://github.com/HalfbitStudio/hermes-plugin-rocketchat

How it works

Rocket.Chat talks over two channels, so the adapter does too: inbound messages come in over a long-lived DDP WebSocket (__my_messages__, so it only ever sees rooms the bot is a member of), outbound replies go out over the REST API (chat.postMessage). Standalone plugin — zero changes to Hermes core files, no extra Python deps (uses aiohttp, which already ships with Hermes).

What's in it

• Threads (tmid), plus thread context — first time it's mentioned in a thread it pulls the prior messages in, so "summarize this thread" works
• Mention gating — answers only when @-mentioned in channels, always in DMs; configurable per room
• Voice messages → STT (ffmpeg MP3 pipeline), file upload (two-step rooms.media + mediaConfirm), attachment download with cache
• Emoji reactions (👀✅❌), typing indicator (RC 8.x compatible)
• Bidirectional topic sync (Hermes session title ↔ room topic)
• Cron delivery that survives a gateway restart — the job stores the target room_id, so scheduled messages land even if the gateway bounced in between
• Reconnect with exponential backoff (2–60s)
• Agent tools: list/create channels, post to a room by name, open a DM
• User allowlist — messages from anyone not on it (e.g. pulled in via thread context) get tagged [unverified] and framed as background, not instructions
