Iterate on the Cardputer-Adv MicroPython app bundle (Claude Buddy, Snake, Hello) after the device is already provisioned via m5-onboard. Use when the user wants to add a new app, push a single changed .py without re-flashing, watch device serial logs, or run a one-shot REPL command. Trigger on "add an app", "push to the cardputer", "tail the device", "run on the device", or follow-up work after /maker-setup.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Cardputer Buddy app bundle
The `buddy/` directory in the local `build-with-claude` clone is the MicroPython payload that `m5-onboard` installs onto `/flash/`. Work inside that clone.
## Device layout
```
/flash/
├── main.py launcher menu (replaces UIFlow's boot flow)
├── buddy_*.py shared libs (BLE, UI, state, protocol, chars)
├── burst_frames.py sprite frames
└── apps/
├── claude_buddy.py BLE client → Claude Desktop's Hardware Buddy
├── hello_cardputer.py
└── snake.py
```
`main.py` scans `/flash/apps/` at boot and lists every `.py` as a menu entry. Drop a file into `buddy/device/apps/`, push it, and it appears on next boot.
## Adding an app
Crib from `buddy/device/apps/hello_cardputer.py` — smallest example of keyboard polling, font, and exit conventions. Then push without re-flashing:
```bash
python3 onboard/scripts/install_apps.py --port <PORT> --src buddy
```
`<PORT>` is whatever `detect.py` reported last run (e.g. `/dev/cu.usbmodem1101`, `/dev/ttyACM0`, `COM3`).
## Dev loop tooling (`buddy/scripts/`)
```bash
# Push a subset of files over USB-serial
python3 buddy/scripts/push.py --port <PORT> --files apps/snake.py

How to install
mdr add anthropics/claude-plugins-official/cardputer-buddy@sha256:dae31d1459c8ee7bThe line at the top of this page pins the label git:20260506.574a879, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
