openclaw - 💡(How to fix) Fix Feature: slash command to set preview streaming mode for current chat/session [1 comments, 2 participants]

Feature request

Add a slash/native command to change preview streaming behavior for the current chat/session without editing gateway config or restarting the gateway.

Proposed UX

/stream
/stream off
/stream final
/stream partial
/stream progress
/stream reset

/stream with no args would show the effective streaming mode for the current conversation and whether it is inherited from config or overridden locally.

/stream reset would clear the local override and return to the configured channel default.

An alias like /streaming would also be fine if that fits the command naming style better.

Why this matters

Preview streaming is useful but situational:

• Some chats benefit from partial live previews.
• Some groups are cleaner with final or off to avoid noisy edits / ghost-preview UX.
• Debugging channel behavior often requires switching modes quickly.
• Today this generally means editing channel config and relying on reload/restart behavior, which is awkward for operators and risky during active conversations.

A per-chat/session command would let operators tune delivery behavior where the conversation is happening, without a gateway restart.

Scope preference

Ideally this should be a shared channel capability rather than Telegram-only if practical.

Likely first-class targets:

• Telegram
• Slack
• Discord

Mattermost or other channels could follow if their preview/draft model maps cleanly.

Design questions

I am not presuming the storage layer here. Possible designs:

1. Store a current-session override, similar in spirit to /fast, /verbose, or /reasoning.
2. Store a per-conversation/channel runtime override keyed by channel + chat/thread/session identity.
3. Add a shared channel delivery override abstraction that preview-streaming-capable channels can opt into.

A minimal MVP could skip richer DM-vs-group policy and only support “set/reset effective preview mode for this current conversation.”

Expected behavior

• Command applies only to the current chat/session/conversation scope.
• No gateway restart required.
• Existing config remains the default/fallback.
• /status ideally shows an active streaming override when one is set.
• Unsupported channels should return a clear “not supported on this channel” message rather than silently doing nothing.
