The agent should review the changes using (1) git diff (2) rag on codebase (3) other sources, e.g. web
Yes, I could build this myself using e.g. langchain; however, I think this has been built hundrets of times by now; therefore my question: are there any ready to use agents for this kind of task?

As to the others here working on similar things, I weep for the future.
GitLab may also have a code review tool available now (I know that GitHub does)
