Discord channel

The Discord channel runs a Vystak bot connected to Discord's gateway over WebSocket. Mention the bot in a guild text channel, DM it, or start a thread — all messages route to your agents.

Setup

1. Create a Discord application: discord.com/developers/applications.
2. Add a bot user to the application. Copy the bot token (you will use it as DISCORD_BOT_TOKEN).
3. Enable the MESSAGE CONTENT privileged intent in the bot settings. This is required to read message content (it is a one-checkbox setup; Discord verifies bots once they reach 100+ guilds).
4. Invite the bot to a server with at least the Send Messages, Read Message History, and Use Slash Commands permissions.

Configuration

Add a Discord channel to your agent.yaml:

name: hero
model: anthropic/claude-haiku-4-5-20251001
adapter: langchain
provider: docker
channels:
  - name: discord-prod
    type: discord
    agents: [hero]
    default_agent: hero
    # Optional:
    group_policy: open
    dm_policy: open
    thread:
      initial_history_limit: 20
      require_explicit_mention: false
    register_slash_commands: true
    welcome_message: "Hi! I'm Vystak. Mention me to start."

Pass the bot token via the host environment when running vystak apply:

export DISCORD_BOT_TOKEN=...
vystak apply

Slash commands

Once the bot is in your server, the following slash commands are available (they show up in Discord's UI as /vystak-route, /vystak-status, etc.):

Command	Purpose
/vystak-route	Bind this channel/thread to an agent
/vystak-unroute	Remove the binding
/vystak-prefer	Set a default agent for this scope
/vystak-unprefer	Remove the preference
/vystak-status	Show current routing

Threads + forum channels

Discord native threads and forum channels are treated the same way Slack threads are: when a thread is bound (either explicitly with /vystak-route or implicitly after the first reply), subsequent thread replies go to the same agent. Set thread.require_explicit_mention: true to require an @mention for follow-up replies.

Limits

The Discord channel splits replies longer than 2000 characters into multiple messages (Discord's per-message limit). Streaming and status reactions are not yet supported.
