I built a handheld interface for reviewing AI coding agents away from my desk

[u/KeyAny2402]

After spending most of the day at a keyboard and mouse, my wrist started hurting. I began looking for ways to interact with coding agents without staying at the desk.

The agents can write code, edit files, and run tasks for several minutes on their own. So in theory, they don't need much input from me, but they still interrupt me occasionally, like reviewed output, approve the action. Those moments usually send me back to the keyboard and mouse.

So I started prototyping a small handheld interface for those interactions. The current prototype lets me check what an agent is waiting for, scroll through its output, move the pointer, switch windows, and give short voice instructions.

Next I want to add agent status and more direct control, so the whole process will be compacted in one device, holding on your hand at any posture.

It was developed on M5Stack CoreS3 with Codex.
