"textContent": "Hi @amoywolf\n\nI’d avoid relying on window.openai.userAgent unless OpenAI documents it as a stable contract. I’m not seeing an official Apps/ChatKit doc that guarantees that property, so capability detection is the safer path than UA sniffing.\n\nFor debugging, I’d separate:\n\nwidget logic — reproduce first in browser / standard ChatKit flow\n\nhost-specific behavior — then compare against the app surface\n\nOfficial starting points:\n\nChatKit overview: https://platform.openai.com/docs/guides/chatkit\n\nChatKit widgets: https://platform.openai.com/docs/guides/chatkit-widgets\n\nAdvanced/custom ChatKit integrations: https://platform.openai.com/docs/guides/custom-chatkit\n\n\n\nSo my rule would be: don’t depend on undocumented host detection, prefer feature checks, and isolate web-vs-app behavior with strong widget-side logging.",
