I kept seeing those ESP32 toys where you plug it to your PC / Linux and have a touch screen change when Claude Code / Cursor / Codex is asking for some permission, but I didn't want to go that far. I also missed a way to remote control the agent chat when away from the computer. I glanced at my mobile and then it hit me: why not bluetooth? BT got a decent reach, doesn't depend on WiFi (specially with AP isolation), never exposed to the internet (looking at you TailScale). So here's my first attempt. There are some rough edges on Linux, non-working on OSX, but we'll get there.
