Recently, a story has exploded in the tech circle—an Australian developer, Geoffrey Huntley, used just 5 lines of code to break through the ceiling of AI programming.

By the end of 2025, this guy wrote a minimalist Bash script:

while :; do cat PROMPT.md | claude-code ; done

Just these five lines. It sounds unremarkable, but no one expected that in just a month, this small script would trigger a technological storm. The previously popular Claude Code, combined with this automation script, completely rewrote the way programming is done.

How powerful is this combination? Even the founder of Claude Code hasn't handwritten code in 30 days. Not only that, but it has also spawned a whole new category of development tools, from Cursor to Windsurf, and the programming assistants launched by various large models. The entire ecosystem is beginning to revolve around automated programming.

What we are witnessing is not just an upgrade of tools but a fundamental shift in software development methods. From manual coding to letting AI handle iterations, the role of developers is being redefined. Some worry about job security, while others see the dawn of a productivity revolution.

This event gives everyone an insight: sometimes, what changes the world isn't complex systems, but those seemingly simple yet incredibly clever ideas.
