As a solo dev or rather nowadays more so only a decision maker / agent overseer, I came to enjoy letting my agents develop against a Gerrit repository / workflow. Dev agent pushes a CL, review agent picks it up (not just the diff, but the full repo), runs tests/reviews/review-subagents and concludes by posting a review as well as a vote. This goes back and forth with new patch sets / replies to the threads. Eventually the CL gets a +2 or whatever and I have the final call to manually submit it.
It is way slower compared to just pushing through development with one agent doing everything yolo against a normal repository, but it seems to me that the additional time is well spent (no, I don't have fancy graphs or similar analysis to prove this other than my gut feeling after looking at recent development results).

I’d prefer to have that happen as some sort of pre commit hook, before a merge request is sent. The feedback loop might be a bit faster and the process might produce less noise this way.
My company has the AI review agents, and you can run them locally, but practically it’s easier to just open a merge request to have CI run the agents. Especially if you’re juggling a bunch of merge requests.
Valid, but you lose the lived history that comes with the audit log of it being actual review back and forth and CI runs vs lost to a developers machine and only a relic in the commit log. I can see both sides, though.
Can you elaborate about the practical value of having the history of back and forth, in a PR or even in the commit log? In my 20ish years of experience, I can’t recall a single instance where I’ve solved something thanks to having this work-in-progress state persisted in the repo history.
It’s exclusively been the other way around where having a smaller number of larger squished commits (post merge) that’s made the project be more maintainable.
I have mixed feelings, but it boils down to how long it takes and / or cost.
Pre-commit hooks should be fast, as it's something you'd do (normally) a few dozen times a year. I don't believe sending a review job to a remote agent is fast, nor will waiting for a review to finish a commit be good for anyone.
CI on the other hand can be slower and runs async, it's fire and forget so you can switch tasks.
If noise is an issue, one possible solution is to create a merge request, have the tools review it, make the fixes, rewrite history like you did it perfectly the first time ("fix" commits are noise), then create a new one for human review.
I built a more naive version for our team using Copilot and GitHub actions and it works quite well (wish I had metrics too). The team loves it.
The ROI here is so high that I don't mind using the strongest model available for the actual code review. I don't trust Sonnet and such. Just let Opus or GPT 5.5 do the whole thing and pay a bit more for less complexity.
I think approaches like this don't need to run other than locally. Maybe integrated as pre-push hook. The system is nondeterministic, so it's at odds with the purpose of CI.
Human review is about learning and there's an implied social contract in that someone is giving you their time to make you better. It isn't necessarily necessary but replacing it with AI shows a fundamental misunderstanding of why it is part of the process.
I'd argue it's pretty much like monitoring, which certainly benefits from multiple people seeing the same stats and alerts. I agree it's at odds with CI/CD and should probably not block anything, like deterministic checks commonly do.

I had the same problem in my recursive agent harness. It would always come back, but it could sometimes take up to 10 minutes depending. I fixed this by adding a required "purpose" argument to every tool and call/return event. As the recursive evaluation proceeds, every single thing that happens streams incremental purpose text to the user's browser (also using the magic of JSONL for this). The incremental progress events contain the purpose and a detail section (tool arg JSON) that the user can expand/collapse.
Every iteration something can be found. How many times do you iterate e.g. on performance - use optimized struct, oh, you can change the architecture etc.? At that point one can just have a while loop for the agents to make changes until no comments left.
You can do basically the same thing as cloudflare except as a skill you run in your local harness. If you're going through the motions with PRs and are familiar with actions, you can have it run in a github action instead. But this is basically just a skill. The Claude code review skill is a simple version of exactly this.

People usually squash merge anyways

You must have some pretty monster commits.

do you also have separate prompts for each domain (security, architecture etc?).
would love to look into it if any part of it is open source

I'm not sure the people integrating it into CI process understand what CI is.
Same can be said about human review if the argument is non-determinism.

Nice trick! I am doing something similar but passing those incremental updates to Haiku for a short user-friendly message.

What’s the over/under on when Cloudflare will acquire OpenCode (and keep it open source)?
what's best workflow for solo devs?
