Discord (Via message)

Use the message tool. No provider-specific discord tool exposed to the agent.

Musts

• Always: channel: "discord".
• Respect gating: channels.discord.actions.* (some default off: roles, moderation, presence, channels).
• Prefer explicit ids: guildId, channelId, messageId, userId.
• Multi-account: optional accountId.

Guidelines

• Avoid Markdown tables in outbound Discord messages.
• Mention users as <@USER_ID>.
• Prefer Discord components v2 (components) for rich UI; use legacy embeds only when you must.

Targets

• Send-like actions: to: "channel:<id>" or to: "user:<id>".
• Message-specific actions: channelId: "<id>" (or to) + messageId: "<id>".

Common Actions (Examples)

Send message:

{
  "action": "send",
  "channel": "discord",
  "to": "channel:123",
  "message": "hello",
  "silent": true
}

Send with media:

{
  "action": "send",
  "channel": "discord",
  "to": "channel:123",
  "message": "see attachment",
  "media": "file:///tmp/example.png"
}

• Optional silent: true to suppress Discord notifications.

Send with components v2 (recommended for rich UI):

{
  "action": "send",
  "channel": "discord",
  "to": "channel:123",
  "message": "Status update",
  "components": "[Carbon v2 components]"
}

• components expects Carbon component instances (Container, TextDisplay, etc.) from JS/TS integrations.
• Do not combine components with embeds (Discord rejects v2 + embeds).

Legacy embeds (not recommended):

{
  "action": "send",
  "channel": "discord",
  "to": "channel:123",
  "message": "Status update",
  "embeds": [{ "title": "Legacy", "description": "Embeds are legacy." }]
}

• embeds are ignored when components v2 are present.

React:

{
  "action": "react",
  "channel": "discord",
  "channelId": "123",
  "messageId": "456",
  "emoji": "✅"
}
