Expected behavior

When slack.require_mention: false is set in config.yaml, the bot should respond to all messages in subscribed channels (where message.channels event is subscribed), even without @mention.

Actual behavior

The bot only responds to:

• Messages with @mention
• Replies in threads where it was previously mentioned
• Existing thread sessions

Messages without @mention in non-threaded channels are ignored, even with require_mention: false.

Root cause

In gateway/platforms/slack.py around line 833, the code reads require_mention from self.config as a direct attribute, but it's actually stored in self.config.extra['require_mention'] (see gateway/config.py lines 529-543).

Fix

Change line 834 in gateway/platforms/slack.py from:

require_mention = getattr(self.config, 'require_mention', True)

To:

require_mention = self.config.extra.get('require_mention', True)

Workaround

Patch ~/.hermes/hermes-agent/gateway/platforms/slack.py with the fix above, then restart the gateway.
