Unclear Whether the shared list differs from the old fixed one, and so whether any mention behaves differently, is not clear.
What
You can mention an agent in your prompt with @ followed by its name. Claude Code only treats it as a mention when the @ starts the text or follows certain characters. That list used to be fixed: a space, or the Chinese and Japanese punctuation marks 。、？！. It now comes from a list shared with other mention rules.
Why
The characters that may come before an @ mention may now differ from before.
