feat(config)!: default allow_user_messages to multibot-mentions#1126
Merged
Conversation
BREAKING CHANGE: The default value of allow_user_messages is now "multibot-mentions" instead of "involved". Existing deployments that do not explicitly set this config will now require @mention in multi-bot threads. To restore the previous behavior, explicitly set: allow_user_messages = "involved" in your config.toml or Helm values.
- Move #[default] in gateway Feishu AllowUsers enum - Update FEISHU_ALLOW_USER_MESSAGES env var fallback - Fix remaining 'involved (default)' references in messaging.md, discord.md, and feishu.md
- F1: fix outdated comment in messaging.md example block - F2: remove duplicate multibot-mentions row in feishu.md table - F3: fix FeishuConfig::default() hardcoded to Involved

Summary
Caution
BREAKING CHANGE — Changes the default value of
allow_user_messagesfrom"involved"to"multibot-mentions".Motivation
In multi-bot deployments (which is the common setup for OpenAB),
"involved"causes all bots to respond to every message in a shared thread. This is noisy and confusing."multibot-mentions"is already the recommended mode in our docs for multi-bot setups, so making it the default aligns with best practice.In single-bot threads,
"multibot-mentions"behaves identically to"involved"— no user-facing change for single-bot deployments.Migration
Existing deployments that rely on the old default and want all bots to respond in multi-bot threads without @mention should explicitly set:
or in Helm:
