That instruction now goes further: a site asking automated clients for contact details, such as an email in the User-Agent (the line a program sends to identify itself to a website), is not a reason to use your address. Claude is told to use a generic client name or ask you instead.\n\n**Why**\n\nThis keeps your email address from ending up in requests Claude makes to websites.\n\n- Area: System Prompt\n- Names: `CLAUDE_CODE_USER_EMAIL`\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
