That request now includes a User-Agent header, a line that names the program making the request. It previously carried only the login and API headers.\n\n**Why**\n\nThis is a small change, but anything that inspects Claude Code's outgoing traffic, such as a corporate proxy, will now see this request identified.\n\n- Area: API Requests\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 3\/5"}
