Mention @Claude in a thread or channel

If Claude posts something you didn't intend to share, you can delete its message from the thread.

What context from the thread or channel is included when using @Claude?

When mentioned in a channel, Claude will have access to the last 20 messages in that channel, including any files shared within those messages. When using @Claude in a thread, it will have access to the last 50 messages in that thread.
