Summary

When using channels.slack.accounts to connect multiple Slack workspaces, messages are received from both workspaces correctly, but cross-account sending does not work.

Setup

{
  "channels": {
    "slack": {
      "enabled": true,
      "botToken": "xoxb-...",  // Workspace A (primary)
      "appToken": "xapp-...",
      "accounts": {
        "workspace-b": {
          "name": "Workspace B",
          "botToken": "xoxb-...",
          "appToken": "xapp-..."
        }
      }
    }
  }
}

Behavior

• ✅ Receiving messages from both workspaces works
• ✅ Replying in the same workspace works (auto-routed)
• ❌ Sending to a channel in Workspace A while in a session triggered from Workspace B fails with channel_not_found

Expected

The message tool should support an accountId parameter (or similar) to explicitly target a specific workspace account for sends.

Workaround Attempted

Tried using the message tool without specifying accountId, hoping it would fall back to the primary account - still got channel_not_found.

Environment

• Clawdbot version: 2026.1.24-3
• Both workspaces use Socket Mode
• Both apps are installed and have the bot invited to relevant channels

Questions

1. Is cross-account sending supported?
2. If not, is this planned?
3. Any workaround besides running separate gateway instances?

Thanks! 🌻
