A setup workflow for M5Stack ESP32 development boards, including Cardputer models and Core devices.

Use it to provision a freshly connected M5Stack over USB, install the Claude Buddy app bundle, and prepare the device for development.

It reduces the manual work of detecting a board, flashing its firmware, and copying MicroPython apps onto it.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

m5-onboard scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

A mod that escalates privileges can change anything on the machine, not only the project.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Python itself has to exist before this skill can do anything — you can't bootstrap an interpreter from inside one. `git` is **not** required — the `/maker-setup` command falls back to downloading the GitHub tarball with

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 + LCD + speaker + button check).
User wants to know what's on the bus / what the device can do → smoke_test.py.

If multiple devices are plugged in, ask which port to target — don't guess. If the user is provisioning a device they previously worked with (e.g. "same thing as last time" or "another Buddy"), default to --apps buddy unless they say otherwise.

Which variant to assume

The rig this skill lives on provisions Cardputer-Adv boards overwhelmingly, so onboard.py now defaults to --variant cardputer-adv. In practice that means:
