router-for-me/EasyCLIProxyAPI ? reverse-engineered prompt

Build me a desktop app for managing CLIProxyAPI that feels simple for everyday use.

I want a clean GUI where I can start, stop, and restart the local proxy, see whether it is running, what port it is on, and copy ready to use endpoints for OpenAI, Claude, and Gemini style apps. It should also handle OAuth sign in flows for supported providers, let me add and manage upstream API accounts in one place, and convert requests and responses between the common formats when needed.

Please include a usage screen that shows request history, token counts, success rate, and estimated cost, plus a way to filter and inspect details. I also want an agents section that detects installed clients like Claude Code or Codex and helps connect them to the local proxy, save a backup first, and restore settings later.

Make it desktop friendly, support macOS menu bar and Windows tray behavior, and bundle the core so first time setup is easy.
