Hermes Agent Slack puts your agent where your team already talks. It connects with Socket Mode, so your laptop or private server doesn’t need a public URL, and every Hermes command shows up as a native Slack slash command. Here’s the setup from the official docs.
Key takeaways
- Generate a ready-made Slack manifest with one Hermes command.
- Socket Mode means no public URL and no open ports.
- DMs need no mention; channels reply in threads.
- Every Hermes command becomes a Slack slash command.

Why the gateway matters in v0.23
Hermes’ messaging gateway is one background process that connects to every platform you set up, keeps the sessions, runs cron jobs and delivers voice messages. Since v0.23.0 (5 November 2026), one gateway on each machine owns every conversation, and the CLI, TUI, Desktop, editors, bots and cron all attach to it. A chat you start in one place is the same chat everywhere, with one queue and one history.
The latest patch, v0.23.1 (9 November), fixes plugin installs so hermes plugins install sees the live catalog again. Update with hermes update.
1. Create the app from the Hermes manifest
The fastest route in the Slack docs is a manifest Hermes writes for you. It declares every slash command, OAuth scope and event, and turns on Socket Mode.
hermes slack manifest --agent-view --writeThen go to api.slack.com/apps → Create New App → From an app manifest, pick your workspace, paste the JSON and create it. New apps use Slack’s Agent view, which can’t be switched back to the older Assistant view.

2. Tokens, install and invite
- Create an App-Level Token with
connections:write(it starts withxapp-). - Install the app to your workspace and copy the Bot Token (
xoxb-). - Add the Member IDs of the people allowed to use it.
- Run
hermes gateway setup, pick Slack, then start the gateway. - Invite the bot to each channel with
/invite. It never joins channels by itself.
Old classic Slack apps were deprecated in March 2025, so build a new app if you have one of those.
3. How it behaves in DMs, channels and threads
- DMs: it answers every message, no mention needed.
- Channels: it only answers when @mentioned, and replies in a thread.
- Threads: once it’s active in a thread, follow-ups don’t need a mention.
For busy threads where people talk to each other, the opt-in thread_followup_silence setting from v0.22.7 lets the bot stay quiet on replies that aren’t meant for it.
4. Slash commands, buttons and live progress
Type / and Slack lists every Hermes command with its description: /model, /stop, /new, /btw and the rest. Slash replies are private to you, and inside threads you can use the !cmd prefix. Clarifying questions arrive as one-tap buttons.
You can also turn on live-typing replies, task cards that show tool progress, a channel allowlist, reaction triggers and support for more than one workspace.

5. Scheduled work into Slack
Set a home channel and cron jobs post their results there, so a morning report or a weekly summary lands where the team will read it. Since v0.23.0 those jobs run through the same gateway as your chats.
Keep it locked down
The gateway’s default is safe: it denies everyone who isn’t on an allowlist or paired. You can list user IDs per platform, or let unknown people DM the bot for a one-time pairing code that you approve with hermes pairing approve. Codes expire after an hour.
The docs call allowing all users “NOT recommended for bots with terminal access”, and that’s the right call for any business. Keep the allowlist short and use /approve and /deny for risky commands. In Slack, the Agent view passes the channel you’re looking at only as a label. Hermes doesn’t read that channel’s history.
My verdict
Paste the manifest, invite the bot to one channel and start in DMs. Because there’s no public URL and every command is native, Hermes Agent Slack is the easiest way to bring your agent to a whole team.
