openclaw - 💡(How to fix) Fix Mattermost streaming partial: final edit doesn't trigger notification [2 comments, 1 participants]

Bug Description

When using streaming: "partial" in Mattermost, the user receives a notification when the draft preview post is created (at the start of tool/reasoning activity), but does NOT receive a notification when the final answer is edited into the post.

This creates a poor UX where:

1. User gets notified "someone posted" → opens app → sees incomplete draft/thinking
2. Final answer arrives as an edit → no new notification → user has no idea the answer is ready
3. User is left waiting or misses the response entirely

Expected Behavior

The final answer should trigger a notification (or the draft should be created silently and only the final post should notify).

Actual Behavior

• Draft preview post creation triggers notification
• Final edit replaces content silently (no notification)

Reproduction

1. Configure Mattermost channel with streaming: "partial"
2. Send any message that triggers tool usage (causing a draft preview)
3. Observe notification on draft creation
4. Wait for final answer → no new notification

Suggestion

Possible fixes:

• Option A: Add a config flag like final_notification: true that sends a brief ephemeral/follow-up ping or re-creates the post as new when finalized
• Option B: Create the draft preview silently (no notification) and only send notification on final post (but this may break real-time feedback expectation)
• Option C: Add an optional mention or ping action when finalizing the stream

Environment

• OpenClaw with Mattermost channel
• streaming: "partial"
• Mobile/desktop Mattermost clients
