# M5Stack Onboarding This skill automates the full cold-start workflow for an M5Stack ESP32 device: detect on USB, identify model, flash UIFlow 2.0, and push a MicroPython app bundle onto `/flash/` so the device boots into user software. The apps we ship (Claude Buddy, Snake, Hello) talk over BLE or USB. The workflow runs on macOS, Linux, and Windows; the skill was developed against an M5Stack Basic v2.6 (CH9102 bridge, ESP32-D0WDQ6-V3, 16 MB flash) and generalized to cover the rest of the Core family, with the Cardputer-Adv (ESP32-S3, native USB) as the current default target. ## Where the scripts live This skill ships as part of the `cwc-makers` plugin for reference, but the executable scripts and the `buddy/` app bundle live in a local clone of https://github.com/moremas/build-with-claude (the `/maker-setup` command creates this clone). Run every `scripts/*.py` invocation below from inside that clone's `onboard/` directory so `--apps buddy` resolves to the sibling `buddy/device/` payload. ## When to use Use this when a user plugs in an M5Stack device and wants it provisioned. The decision tree: - **Fresh/unknown device** → run `onboard.py --apps buddy` end-to-end (detect → identify → flash → install apps). This is the default path. - **Already-flashed device, user just wants apps installed/refreshed** → run `install_apps.py --src buddy` (or any `--src <path>` to a directory of `.py` files). - **Flashed device, something feels broken** → run `smoke_test.py` (I2C + LC...
