hardware-security
Lets your agent research hardware and embedded interface security, like UART and JTAG.
What it does
This tool helps investigate the security of a device's physical components, like hidden communication ports (UART/JTAG) and the secure boot process. It's used to understand how a device starts up and if its hardware protections can be analyzed.
When to use it
- ✓When physically reviewing the security of a device you own or are authorized to test.
- ✓When locating and documenting exposed debug interfaces on hardware.
- ✓When trying to understand a device's secure boot process.
Example of what to ask your AI
“I want to analyze the physical security of this device I own. Can you help me find and document the debug interfaces?”

How it works
The tool works by physically connecting to the device's hardware to discover communication ports and analyze its startup process. It can identify test points and record important hardware information.
Installation
Easiest way: copy the skill link and paste it into Claude, ChatGPT or Cursor asking it to follow the instructions.
In the terminal (Claude Code, Codex, Cursor), in your project folder:

⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.
Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:
- Ask the user to state the exact target URL, IP, account, or resource.
- Ask the user to confirm written authorization and the permitted scope.
- Show the exact command(s) and explain their expected effect.
- Wait for explicit confirmation in the current conversation.
Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.
Hardware / Embedded Interface Security
When to Use
- Physical security review of a device you own or are authorized to test.
- Locating and documenting exposed debug interfaces.
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
□ 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 |

路由上下文
上游: MASTER R34
MUST NOT: 未授权拆机/损坏他人设备
任务完成自检
- 是否记录接口电平与引脚图？
- 镜像是否哈希保全？
- Checklist？
Limitations
- Requires physical access and basic HW tooling (adapters, multimeter).
- Soldered or disabled debug ports raise the difficulty sharply.

FAQ
Do I need permission to use this tool?
Yes, this tool is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using it.
What are UART and JTAG?
UART and JTAG are types of interfaces (ports) on electronic components used for communication and debugging, often hidden or used by engineers to test hardware.
Can this tool damage my device?
The tool is designed for analysis and should not damage the device if used correctly and with authorization. However, it requires physical access and basic hardware tooling, and misuse can be illegal.
