Agent Andon Light v0.2.0
A status light for Claude Code and other coding agents.
Green while it's working, yellow when it's waiting on you, red when it's idle.
Ten LEDs. A USB-C board. A small CLI.
Ten addressable LEDs behind a diffuser, wired to a USB-C dev board, driven by a small Python CLI (a program you run by typing a command, not something with a window or icon). Claude Code and Codex CLI hooks send state changes to the CLI, which updates the light: green while it's working, yellow when it's waiting on you, red when it's idle.
No terminal to check, no app to open.
A terminal or dashboard only tells you something if you're looking at it. This doesn't. It sits on your desk and shows the same thing whether you're at your keyboard or not.
Four states, one glance.
- Working
- The agent is doing something.
- Waiting
- It needs you: a permission or an answer.
- Idle
- Nothing running right now.
- Compacting
- Housekeeping. Still alive, not stuck.
Open hardware, honestly a hobby project.
MIT-licensed: schematics, firmware, and CLI all included. Linux and Windows supported today. Not a commercial product, not for sale. Built because a physical light is more fun to build, and more useful to have, than another terminal tab.
