Feature Request: CodeRabbit or Greptile AI PR reviews

[karlhorky]

Describe the Feature

Add a free open source installation of either:

1. CodeRabbit
2. Greptile
3. others

I've had good experience with CodeRabbit. Some other people have said that Greptile is better.

Why do you want this feature?

Currently, PRs are reviewed by GitHub Copilot.

This is a good start, but often Copilot creates AI slop:

1. False positives (incorrect feedback)
2. False negatives (missed bugs / problems)

I personally don't really see a need for this. The volume of pull requests is very low in this repository. I think by the time a next PR arrives, these tools might be completely outdated. I'm not totally against this, but just doubtful.

I also noticed these pretty useless Copilot code reviews appearing today. I though... where are these coming from... and it turns out that these automatic reviews happen when the author of the PR himself has this feature enabled. So, maybe these alternative ones can also be set up so that they'll review your PR-s if you want so.

I don't see this happening - these have been pretty stable recommendations for ~1 year or so, and they keep getting better.

It has picked up some good edge cases in a lot of PRs that I've done.

I would suggest giving it a shot on 3+ PRs before you make a decision.

Otherwise, we can close this issue.

Well, as I said. I'm not against it. We can definitely give it a try. If you want to set these up, then go ahead.

I gave you the maintainer rights. Maybe that's not enough to do this. Ping me, if in need.

[karlhorky]

Ok, I requested adding the coderabbitai GitHub App - I guess you should see a notification or something.

[nene]

Yep. Approved it.

[karlhorky]

Great, first review over in my new PR (with an actionable suggestion for mixed case in the test - already applied it to the PR):

• Add support for PostgreSQL keywords in CREATE CONSTRAINT TRIGGER #948

Closing.

So... I experienced the first CodeRabbit comment on a pull request: #953 (comment)

And I have to say I found its utility to be somewhere between completely useless to actively harmful:

• It reported issues like "Docstring coverage is 0.00%", which is completely irrelevant to this project.
• It contained lots of noise. And I mean, a lot. It even wrote a poem about the PR. Like WTF?
• It modified the description of the pull request to add its own summary. IMHO, not cool. Especially as the author had already written a perfectly good description. If I were the author, I would feel insulted.

I've seen many AI-generated pull request reviews, and this was the pretty much the worst I've ever seen. Like, my expectations were low to begin with, but this managed to be way worse still.

[karlhorky]

Understood. I've never had issues with those things, but apparently all 3 are configurable:

• Improve Coderabbit config with .coderabbit.yaml #955

[nene]

Good. Let's see if things get better after the fluff gets removed.
