I'm glad you can.

Even before agents, I'm pulled to work on at least a couple different projects a year, the successful ones with teams of 10s of people working on them. If I stay longer than a couple of months, I eventually become the expert on some of the things I did, so I get pulled years later to review something I haven't touched in ages, which has changed requirements and grown a bunch of dependents.

That was the reality of working on a team with hundreds of people and dozens of related products.

Now agents are “helping” people increase complexity and velocity 10-fold.

You can call it a problem in the coal mine, but there's no going back. GitHub simply has no choice but to handle this new scale.

I could, before LLM-authored PRs. They broke all my heuristics for what to check. LLMs can write code that looks incredibly professional and well thought out, and nowadays they almost never make the usual human mistakes (like off-by-one errors). But at the same time, they can make incredibly silly mistakes of the kind people would never make (like inventing brand-new parameters for some remote API call).

It feels like everything I’ve learned over the years about reviewing code no longer applies.
