GitHub Tries to Unf**k Giant AI Pull Requests with “Reviewable Stacks”

Right, so GitHub has apparently noticed that AI-generated pull requests have become enormous, bloated piles of crap that nobody sane wants to review in one sitting. You ask the machine for a “small refactor,” and the damn thing vomits out changes across half the repository like a drunk intern with commit access. Their bright idea? “Reviewable stacks.” About bloody time.

The article explains that GitHub is introducing a way to break massive pull requests into smaller, more manageable chunks—stacked changes, basically—so developers can review one sane piece at a time instead of staring into a soul-crushing wall of diffs and wondering which part of the disaster will take production down first.

The point is painfully obvious: giant PRs are a nightmare. AI tools are making this worse by generating huge volumes of code at stupid speed, which sounds impressive right up until some poor bastard has to review it. And review it they must, because letting AI shovel code straight into main without oversight is how you end up spending your weekend in a war room eating stale pizza and swearing at logs.

GitHub’s stacked-review approach is supposed to make code review less awful by splitting changes into logical layers. Instead of one monolithic “here’s 4,000 lines of mystery shit” submission, reviewers can go through smaller steps that actually make sense. In theory, that means faster reviews, fewer mistakes, and slightly less homicidal rage from the engineering team.

There’s also an implicit admission here that AI coding assistants are not the magical productivity unicorns vendors keep wanking on about. Sure, they can generate code quickly. They can also generate a giant heap of interconnected nonsense quickly. Speed is lovely, but if the output arrives as an unreadable sludge pile, then congratulations, you’ve automated the creation of more work.

So the real value of this GitHub move is not that it makes AI smarter—it bloody well doesn’t—but that it gives humans a fighting chance to review the mess in pieces. Smaller, cleaner PR stacks mean reviewers can understand intent, catch bugs earlier, and maybe preserve a shred of sanity before the next auto-generated avalanche rolls downhill.

In other words: GitHub is putting a filing system on top of the chaos machine. It’s not fixing the chaos machine, mind you. It’s just making the chaos slightly less of a complete shitshow to inspect.

Anecdote time. Years ago, I watched a developer submit one “tiny” Friday-afternoon change that somehow touched authentication, database migrations, UI text, logging, and—because apparently Satan was driving—network configs. He said, “It all sort of goes together.” It did, in the same way a car crash is technically a collection of parts moving in the same direction. We spent the weekend unpicking that catastrophe. So yes, if GitHub wants to split today’s AI-generated monstrosities into reviewable stacks, that’s the first sensible bloody thing I’ve heard all week.
