README

M5Stack Claude Code Buddy

A physical companion device for [Claude Code](https://claude.ai/claude-code) built with [M5StickC PLUS2](https://docs.m5stack.com/en/core/M5StickC%20PLUS2). It alerts you when Claude Code needs permission approval and lets you respond (**Allow Once** / **Always Allow** / **Reject**) directly from the device via BLE.

How It Works

Claude Code                    Mac (Python)                  M5StickC PLUS2
    |                              |                              |
    |-- PreToolUse hook fires ---->|                              |
    |                              |-- BLE write (tool info) ---->|
    |                              |                              |-- Buzzer + Screen
    |                              |                              |
    |                              |                              |<- User presses button
    |                              |<-- BLE notify (decision) ----|
    |<-- JSON decision (stdout) ---|                              |
    |                              |                              |
    |-- Allow / Block tool ------->|                              |

When Claude Code wants to run a tool that requires permission, the `PreToolUse` hook sends the request to the M5StickC PLUS2 over Bluetooth Low Energy. The device buzzes, shows the tool name and details on screen, and presents three options. You pick one with the hardware buttons, and the decision flows back to Claude Code instantly.
