1. I absolutely agree there's a bubble. Everybody is shipping a code review agent.

2. What on earth is this defense of their product? I could see so many arguments for why their code reviewer is the best, and this contains none of them.

More broadly, though, if you've gotten to the point where you're relying on AI code review to catch bugs, you've lost the plot.

The point of a PR is to share knowledge and to catch structural gaps. Bug-finding is a bonus. Catching bugs, automated self-review, structuring your code to be sensible: that's _your_ job. Write the code to be as sensible as possible, either by yourself or with an AI. Get the review because you work on a team, not in a vacuum.

Well, it was to share knowledge and to catch structural gaps.

Now you have an idea, for better or for worse, that software needs to be developed AI-first. That's great for the creation of new code but as we all know, it's almost guaranteed that you'll get some bad output from the AI that you used to generate the code, and since it can generate code very fast, you have a lot of it to go through, especially if you're working on a monorepo that wasn't architected particularly well when it was written years ago.

PRs seem like an almost natural place to do this. The alternative is the industry finding a more appropriate place to do this sort of thing in the SDLC, which is gonna take time, seeing as how agentic loop software development is so new.

2. There is plenty of evidence for this elsewhere on the site, and we do encourage people to try it because like with a lot of AI tools, YMMV.

You're totally right that PR reviews go a lot farther than catching issues and enforcing standard. Knowledge sharing is a very important part of it. However, there are processes you can create to enable better knowledge sharing and let AI handle the issue-catching (maybe not fully yet, but in time). Blocking code from merging because knowledge isn't shared yet seems unnecessary.

i think the distribution channel is the only defensive moat in low-to-mid-complexity fast-to-implement features like code-review agents. So in case of linear and cursor-bugbot it make a lot of sense. I wonder when Github/Gitlab/Atlassian or Xcode will release their own review agent.
