M5 Onboard

anthropics/claude-plugins-officialOfficial

This automates the entire cold-start workflow for M5Stack ESP32 devices: plug in your Cardputer, Core, or Stick, and it detects the port, flashes UIFlow 2.0 firmware, and installs a MicroPython app bundle (Claude Buddy BLE client, Snake, Hello) onto `/flash/` so the device boots into working software. Built for macOS, Linux, and Windows. It defaults to Cardputer-Adv since that's what most people are provisioning, but handles the full Core family. The flash stage requires a manual button dance on native USB boards (hold G0, tap RST, release), so you need to relay that to users when the script prompts. Run it backgrounded with tee and tail to see progress in real time.

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.
