openclaw - 💡(How to fix) Fix Feature: Attention window for group chats (auto-listen after mention) [1 participants]

Summary

After receiving a mention in a group chat, the agent should auto-listen to all messages for a configurable duration (e.g. 15 minutes), then revert to mention-only mode. This avoids the friction of needing to @ the agent for every follow-up message in a conversation.

Motivation

In Slack (and other platforms), the current requireMention setting is static — either the agent sees everything or only mentions. In practice, when someone starts a conversation with the agent, they want a back-and-forth without @-ing every message. But having it listen to everything all the time wastes tokens and creates noise.

An attention window solves this elegantly: mention once to get the agent's attention, then have a natural conversation for X minutes before it goes quiet again.

Proposed Config

channels:
  slack:
    attentionWindow: 900  # seconds (15 min) — 0 or omitted = current behavior

Behavior

1. Agent receives a mention → starts attention window timer
2. During the window, agent processes all messages in that channel (as if requireMention: false)
3. When the window expires, reverts to mention-only
4. Any new mention during an active window resets the timer
5. Should work across all platforms: Slack, Discord, Telegram, etc.

Additional Context

Requested by a user who found it tedious to @ the agent for every message in a multi-message conversation.
