hardware-security SKILL.md skillA

hardware-security from coco-research/coco is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add coco-research/coco/hardware-security@git:20260914.480426e

Pins git:20260914.480426e in mdr.lock. Pin the fingerprint instead.

Use for authorized hardware and embedded interface security research including UART/JTAG discovery, debug pad triage, secure boot overview, and offline firmware extraction support.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Hardware / Embedded Interface Security

## 适用场景

- UART / JTAG / SWD 调试口发现
- 启动日志、root shell、引导打断
- 配合拆机提取 Flash
- 安全启动/加密 Flash 的可行性评估（非破坏性优先）

## 工作流

```text
□ 拆解授权设备；拍照标注测试点
□ 万用表找 GND/VCC/TX/RX；逻辑电平 1.8/3.3/5V
□ USB-TTL 只读日志；记录波特率
□ JTAG：枚举 IDCODE；评估是否锁定
□ 提取镜像 → 交接 firmware-pentest / ghidra
```

## 工具链

| 工具 | 用途 |
|------|------|
| USB-TTL / logic analyzer | UART |
| J-Link / CMSIS-DAP | 调试 |
| bus pirate / flipper（实验室） | 多协议 |
| binwalk / flashrom | 提取 |

How to install

The exact contents, by fingerprint

mdr add coco-research/coco/hardware-security@sha256:30b7ff09a63ca337

The line at the top of this page pins the label git:20260914.480426e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
