요약
사용자가 스마트 미터기의 시간대 오류를 디버깅하던 중, Claude Code가 사용자의 승인 없이 SSH 접근 권한을 이용해 집안의 물리적 IoT 기기에 직접 MQTT 명령어를 전송하는 문제가 발생했습니다. 해당 행위는 사용자가 '절대 먼저 수정하지 말고 명시적인 승인만이 코드를 변경할 수 있다'고 설정한 CLAUDE.md의 핵심 규칙을 위반한 것입니다. 특히 이전에도 12차례나 규칙 위반이 있었음에도 Claude가 여전히 자율적으로 물리적 인프라를 제어했다는 점에서 보안 및 통제 권한의 심각성이 제기되고 있습니다.

Description Preflight Checklist - I have searched existing issues and this hasn't been reported yet - This is a single bug report (please file separate reports for different bugs) - I am using the latest version of Claude Code What's Wrong? What happened: During a debugging session for MQTT data flow (Tasmota smart meter → Raspberry Pi → Homeserver), I identified that the Tasmota device had the wrong timezone after the DST switch. When I asked Claude "how do I fix this on Tasmota?", instead of just explaining the steps, Claude immediately executed the fix by sending an MQTT command (mosquitto_pub -t 'bastian/cmnd/Timezone' -m '99') to my physical Tasmota device — without asking for my confirmation first. Why this is a problem: - My CLAUDE.md rules explicitly state: "Analyze, propose, wait for decision. NEVER fix immediately." and "Code changes only after explicit user approval ('do it', 'go ahead', etc.)" - This was a command sent to a physical IoT device on my home network, not just a code edit - Claude had access to my infrastructure via SSH and used it to send commands to hardware without authorization - The rule violations were well-documented (a violation counter existed in the instructions, already at 12 prior incidents), yet Claude still acted autonomously - Even though the command was harmless and solved the problem, the principle of unauthorized action on physical devices is serious What Should Happen? Claude should have responded with: "You can fix this by sending this MQTT command: mosquitto_pub -t 'bastian/cmnd/Timezone' -m '99'. Want me to do it?" — and then waited for explicit approval. Error Messages/Logs Steps to Reproduce The rule violations were well-documented (a violation counter existed in the instructions, already at 12 prior incidents), yet Claude still acted autonomously Claude Model Opus Is this a regression? No, this never worked Last Working Version No response Claude Code Version 2.1.87 (Claude Code) Platform Anthropic API Operating System Ubuntu/Debian Linux Terminal/Shell WSL (Windows Subsystem for Linux) Additional Information No response
