What cwc-makers does

Run /maker-setup to clone moremas/build-with-claude, detect a Cardputer-Adv connected over USB-C, flash UIFlow 2.0, and install the Claude Buddy, Hello, and Snake app bundle. Setup includes one manual step: pressing the download-mode button on the back of the device.

The host machine needs Python 3.10 or later. Git is optional; without it, the command falls back to downloading the repository with curl and tar. The onboarding scripts install esptool on first run. Check the Python version before starting setup.

After onboarding, the cardputer-buddy skill can push app updates to the device and work with its REPL without reflashing. The m5-onboard skill covers device detection, firmware flashing, and installation.

# cwc-makers

Seamless onboarding for the [Code-with-Claude Makers](https://claude.com/cwc-makers) Cardputer kit.

## What it does

Plug in your M5Stack Cardputer-Adv over USB-C, type `/maker-setup`, and Claude will:

1. Clone [`moremas/build-with-claude`](https://github.com/moremas/build-with-claude)
2. Detect the device, flash UIFlow 2.0 firmware, and install the Claude Buddy + Hello + Snake app bundle
3. Walk you through the one physical step (the download-mode button press on the back of the device)
4. Hand you a working pocket computer that pairs with Claude Desktop over BLE

Then ask Claude to build whatever you want next — a magic 8-ball, a pixel pet, a weather ticker — and it'll write the MicroPython and push it to the device without re-flashing.

## Install

```
/plugin install cwc-makers@claude-plugins-official
```

## Components

| Path | Type | User-invocable | Purpose |
|------|------|----------------|---------|
| `commands/maker-setup.md` | slash command | ✅ `/maker-setup` | Entry point — clone repo + run full onboarding |
| `skills/m5-onboard/` | skill | ✅ `/m5-onboard` | Full provisioning playbook (detect, flash, install, every gotcha) |
| `skills/cardputer-buddy/` | skill | ✅ `/cardputer-buddy` | Iterate on apps after onboarding (push, tail, REPL) |

`/maker-setup` is the intended entry point; the skills are also auto-triggered by Claude when relevant. Skill content is vendored from the upstream repo so Claude has the domain knowledge in-context without symlinking anything into `~/.claude/skills/`.

## Prerequisites

Python 3.10+ on the host machine (git is optional — `/maker-setup` falls back to a curl+tar download if it's missing). The onboarding scripts auto-install `esptool` on first run; `pyserial` is vendored in the upstream repo.
