openclaw - 💡(How to fix) Fix Discord streaming (tool progress icons) works in DMs but not guild channels

Description

Tool progress icons (streaming mode: "progress" with toolProgress: true) display correctly in Discord DMs but do not appear in guild/channel conversations during normal chat. The final response still arrives, but no in-progress progress message is shown while the agent processes the request.

Environment

• OpenClaw version: 2026.5.27
• Channel: Discord
• Session types affected: Guild channels (isolated sessions agent:<agentId>:discord:channel:<channelId>)
• Session type working: Direct messages (agent:<agentId>:discord:direct:<userId>)

Config

{
  "channels": {
    "discord": {
      "streaming": {
        "mode": "progress",
        "progress": {
          "label": "auto",
          "maxLines": 8,
          "maxLineChars": 120,
          "toolProgress": true,
          "commandText": "status"
        }
      }
    }
  }
}

Investigation findings

1. Streaming config is correct — set globally at channels.discord.streaming with mode: "progress" and toolProgress: true
2. Bot has sufficient permissions — verified ManageMessages (and Administrator) in the guild channel — so editing preview messages should work
3. Gateway healthy — Gateway stability and health checks pass; Discord connection is running, connected, in:just now, out:just now
4. Messages config — messages: {} (defaults); adding explicit messages.groupChat.visibleReplies: "automatic" did not resolve
5. DMs work — same streaming config, same gateway, same bot — tool progress icons show correctly in DM sessions

Expected behavior

Tool progress icons (e.g., "🔎 Web Search", "🛠️ Bash") should appear in guild channel sessions as the progress preview message, identical to DM behavior.

Actual behavior

No progress message appears in guild channels during processing. The final response is delivered directly without any interim progress update.

The gateway logs show message delivery events (message.delivery.started/completed) for the final response, but no progress-related stream events visible for guild channel sessions.
