214214**What it means**
215215
216The channel's [**Respond automatically**](https://claude.com/docs/claude-tag/users/when-claude-responds.md#turn-automatic-replies-on-or-off) setting is on. The setting is on by default.
216The channel's [**How Claude participates**](https://claude.com/docs/claude-tag/users/when-claude-responds.md#turn-automatic-replies-on-or-off) setting lets Claude reply without an @-mention. **Respond automatically** is the default.

218218In a channel where someone has [told Claude which kinds of untagged messages to answer](https://claude.com/docs/claude-tag/users/when-claude-responds.md#what-claude-does-with-a-channel-message), it answers those kinds as well.

220220**How to resolve**
221221
222Turn the **Respond automatically** setting off in the channel where the replies are appearing.
222Set **How Claude participates** to **Only when @-mentioned** in the channel where the replies are appearing.
223223
224224Post `@Claude only respond in this channel when someone @-mentions you` at the channel's top level, not in a thread. Claude confirms the change, which applies to the whole channel rather than to you alone.

226If Claude doesn't confirm the change, turn the setting off on the channel's Configure page:

232232If the Configure page says an admin has locked the channel's settings, ask an admin to [turn automatic replies off](https://claude.com/docs/claude-tag/users/when-claude-responds.md#turn-automatic-replies-on-or-off) for the channel.

234The **Respond automatically** setting doesn't quiet a thread Claude has already posted in. To quiet one of those threads, reply in it with an instruction such as "only respond when I @-mention you".
