The way Claude Code picks these mentions out of your text was rewritten:\n\n- Mentions written as a path followed by a colon and a line number are recognized.\n\n- Mentions placed right next to Chinese or Japanese punctuation such as \u3002\u3001\uff1f\uff01 are separated from that punctuation.\n\n- Repeated characters at the end of a mention are trimmed off.\n\n**Why**\n\nThe set of files attached from your @-mentions may differ slightly from before, especially in prompts written in Chinese or Japanese or that point at a specific line.\n\n- Area: File Attachments\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
