Someone published a repository of plain instruction files (no software, just written guidance) that tells AI coding assistants to stop over-building. It became very popular very quickly. Its original claim about how much code it saved turned out to rest on a bad comparison, and after a contributor pointed that out, the author rebuilt the test properly and published a smaller number.
None of this changes anything on your website today. You will never install it, and it is not a product you can buy. But two things in it are worth your attention.
The first is the underlying problem. AI coding assistants have a habit of writing far more than the job needs. Ask for a contact form and you may get a configuration system, three layers of abstraction and a settings panel nobody asked for. On a small business site, that extra material is not free. Every unnecessary file is something that can break during an update, something a future developer has to read before they can safely change anything, and something that quietly adds to the cost of the next small request you make. "Less code" is not a technical preference. It is a lower bill in eighteen months.
The second is how the claim was handled. A big number got published, someone competent challenged the way it was measured, and the number came down. That is the correct outcome and it is rarer than it should be. When a vendor or a developer tells you a change will make your site three times faster or cut your costs in half, the useful question is not whether the number is impressive but how it was measured, and against what. A smaller honest figure is worth more than a large decorative one.
What to do: nothing urgent. Next time you brief someone on a change to your site, say out loud that you want the smallest thing that solves the problem, not the most flexible thing that might solve future problems. And if a performance or savings claim comes with a big number attached, ask what it was compared against before you act on it.
