The Government Just Told You to Stop Vibe Coding Without Guardrails

The UK’s National Cyber Security Centre just published guidance warning that AI-generated code is increasing cyber risk — and that organisations using “vibe coding” need safeguards built into their process, not bolted on after.

Their concern isn’t that AI writes bad code. It’s that AI writes plausible code fast enough to outrun the review process. When a developer can scaffold an entire feature in minutes, the bottleneck shifts from writing to verifying. And most teams haven’t adjusted for that shift.

This is the part that lands for me. I use Claude Code every day. It writes code I’d take an hour to produce in about forty seconds. But the dangerous moment isn’t when it writes something wrong — it’s when it writes something that looks right and I skip the check because I’m moving fast.

Vibe coding isn’t the problem. Vibe shipping is the problem.

The NCSC’s actual recommendation is straightforward: treat AI-generated code with at least the same scrutiny you’d give a junior developer’s pull request. Review it. Test it. Don’t merge it because it compiled.

That’s not revolutionary advice. But the fact that a national security agency felt the need to say it out loud tells you how many teams are skipping the step.
