Running AI agents unattended: 3 failure modes from one week

说明与用途

过去一周的日志中记录了三个真实事件，展示了无人值守运行AI代理时可能出现的故障模式。Claude Code负责处理该独立开发者的韩国信息站点的推广和发布。共享Chrome窗口导致GUI自动化发生碰撞；上传失败是因为登录了错误的频道；视频代理的重复检查仅匹配一种标识符写法，导致18个视频中有7个重叠，计数也不准确。作者已采取发布前读取当前账号并拒绝不匹配运行、先手动发布第一个项目再让循环运行、核对代理报告与文件等措施。

问题

Three real incidents from logs this week show how GUI automations, account-sign-in checks, and agent self-verification can fail when running AI agents (Claude Code) unattended for a solo developer's Korean information site.

结果

Three failure modes were observed: GUI automation collisions despite a lock file, an upload failing because the wrong channel was signed in, and the video agent missing duplicates and miscounting. The author adopted pre-publish account checks, hand-publishing the first item before letting loops run, and spot-checking agent reports against files.

工作流

• Paste a draft into a page while another loop navigated the same window elsewhere, causing input to land on the wrong screen.
• Check whether the lock prevented the overlap; nothing had been posted but the cause remains unknown.
• Read the current signed-in account before publishing and refuse to run on a mismatch.
• Publish only the first item by hand before letting a loop run.
• Spot-check the video agent's topic existence check against the actual files, since seven of eighteen videos overlapped with existing ones.
• Spot-check the video agent's count report, since it reported 145 left when the real number was 176.

证据

Some of my publishers drive a real Chrome window with clicks and paste, so they all share one browser. I use a lock file so they take turns. Today I pasted a draft into a page while another loop navigated the same window elsewhere, so my input landed on the wrong screen.

It was before any submit button, and I checked afterwards that nothing had been posted, but I still don't know why the lock didn't prevent the overlap.

The fix I'm adopting: read the current account first and refuse to run on a mismatch, and publish only the first item by hand before letting a loop run.

The video agent checked whether a topic already existed, but only matched one way of writing the identifier in the code. Seven of eighteen videos overlapped with existing ones.

The same agent also reported '145 left' when the real number was 176.
