Discord

Bridges Discord to the Workstacean bus. @mentions and slash commands become inbound bus messages; agent replies come back as Discord responses.

How It Works

User @mentions Quinn in Discord
  → DiscordPlugin publishes message.inbound.discord.{channelId}
    → RouterPlugin routes to Quinn or Ava based on skillHint / keywords
      → Agent processes, publishes message.outbound.discord.{channelId}
        → DiscordPlugin sends Discord reply (👀 → ✅)

User runs /quinn bugs
  → DiscordPlugin publishes message.inbound.discord.slash.{interactionId}
    → RouterPlugin routes to Quinn (skillHint: bug_triage)
      → Agent replies
        → DiscordPlugin calls interaction.editReply()

Setup

1. Environment Variables

Variable	Required	Description
DISCORD_BOT_TOKEN	Yes	Bot token (enables the plugin)
DISCORD_GUILD_ID	Yes	Guild ID for slash command registration
DISCORD_DIGEST_CHANNEL	No	Fallback channel ID for cron pushes (overridden by discord.yaml)

The plugin is automatically skipped if DISCORD_BOT_TOKEN is not set.

2. discord.yaml

Place a discord.yaml in your workspace directory (default: workspace/discord.yaml). If absent, the plugin loads with empty commands and default moderation settings.

# ── Channel IDs ───────────────────────────────────────────────────────────────
channels:
  # Default channel for cron-triggered posts (daily digest, etc.)
  # Falls back to DISCORD_DIGEST_CHANNEL env var if blank.
  digest: "1234567890123456789"
  # Channel for new member welcome messages. Leave blank to disable.
  welcome: ""
  # Channel for moderation log. Leave blank to disable.
  modLog: ""

# ── Moderation ────────────────────────────────────────────────────────────────
moderation:
  rateLimit:
    maxMessages: 5
    windowSeconds: 10
  spamPatterns:
    - "free\\s*nitro"
    - "discord\\.gift/"
    - "@everyone.*https?://"
    - "steamcommunity\\.com/gift"

# ── Slash commands ────────────────────────────────────────────────────────────
# Each command is registered to the guild on startup.
# subcommands[].content supports {optionName} interpolation.
# subcommands[].skillHint routes to a specific skill (optional).
#
# Option types: string | integer | boolean
commands:
  - name: mybot
    description: "My bot — project status and reports"
    subcommands:
      - name: status
        description: "Current project status"
        content: "/status"
        skillHint: qa_report

      - name: report
        description: "Generate a report for a version"
        content: "/report {version}"
        skillHint: qa_report
        options:
          - name: version
            description: "Version tag (e.g. v1.2.0)"
            type: string
            required: false

Fields

channels

Field	Description
digest	Channel ID for message.outbound.discord.push.* and cron-triggered posts
welcome	Channel ID for new member welcome messages
modLog	Reserved for future moderation logging

moderation.rateLimit

Field	Description
maxMessages	Max messages per user within the window
windowSeconds	Rolling window in seconds

moderation.spamPatterns

Array of regex strings (escaped for YAML). Matched case-insensitively. Matching messages are silently deleted.

commands[].subcommands[]

Field	Required	Description
name	Yes	Subcommand name (lowercase, no spaces)
description	Yes	Shown in Discord’s command picker
content	Yes	Text sent as the message payload. Use {optionName} for interpolation.
skillHint	No	Tells RouterPlugin which skill to route to
options	No	Slash command options (see below)

commands[].subcommands[].options[]

Field	Required	Description
name	Yes	Option name — also the interpolation key in content
description	Yes	Shown in Discord
type	Yes	string, integer, or boolean
required	No	Defaults to false

Autocomplete Commands

Commands can use top-level options instead of subcommands to get Discord’s autocomplete UX. Set autocomplete: true on any string option to enable live filtering.

When project is an autocomplete option, the plugin loads projects.yaml and returns matching projects as choices (filtered by slug or title). On submission, the project slug is resolved to devChannelId (from discord.dev) and projectRepo (from the github field) and included in the bus payload.

commands:
  - name: report-bug
    description: Report a bug against a project
    options:
      - name: project
        description: Project to report against (start typing to filter)
        type: string
        required: true
        autocomplete: true
      - name: description
        description: Brief description of the bug
        type: string
        required: true
    content: "Bug report for {project}: {description}"
    skillHint: bug_triage

commands[].options[] (flat/autocomplete commands)

Field	Required	Description
name	Yes	Option name — also the interpolation key in content
description	Yes	Shown in Discord
type	Yes	string, integer, or boolean
required	No	Defaults to false
autocomplete	No	When true, Discord sends autocomplete interactions. Only supported on string options. For project options, choices come from projects.yaml.

Flat command bus payload extras

When project is resolved from projects.yaml, two extra fields are added to the inbound payload:

{
  devChannelId?: string;   // discord.dev channel ID for the matched project
  projectRepo?: string;    // GitHub full name (e.g. "protoLabsAI/protoUI")
}

Bus Topics

Topic	Direction	Description
message.inbound.discord.{channelId}	Inbound	@mention or DM
message.inbound.discord.slash.{interactionId}	Inbound	Slash command
message.outbound.discord.{channelId}	Outbound	Reply to @mention or DM
message.outbound.discord.slash.{interactionId}	Outbound	Reply to slash command
message.outbound.discord.push.{channelId}	Outbound	Unprompted push (cron, etc.)

Subscribe to message.outbound.discord.# to handle all outbound Discord delivery.

Inbound Payload

{
  sender: string;       // Discord user ID
  channel: string;      // Discord channel ID
  content: string;      // Cleaned message text (mentions stripped)
  skillHint?: string;   // Set by slash commands and 📋 reactions
  isReaction?: boolean; // true when triggered by 📋 reaction
  isThread?: boolean;   // true when message is in a thread
  guildId?: string;     // null for DMs
}

Outbound Payload

{
  content: string;    // Reply text (truncated to 2000 chars)
  channel?: string;   // Channel ID for push messages (no correlationId)
}

For replies to @mentions and slash commands, match correlationId from the inbound message — no channel needed.

Reactions

Reacting to any message with 📋 triggers a bug_triage skill request using the message content. Useful for quick bug filing from a chat log.

Cron Integration

Cron events routed through RouterPlugin that include a channel in their payload are delivered to Discord via push:

workspace/crons/daily-digest.yaml

- name: daily-digest
  schedule: "0 14 * * *"
  topic: cron.daily-digest
  payload:
    content: "Generate the daily QA digest"
    skillHint: qa_report
    channel: "1234567890123456789"

If channel is omitted, the plugin falls back to channels.digest from discord.yaml, then to DISCORD_DIGEST_CHANNEL.

The bot requires the following:

Scopes: bot, applications.commands
