What are the best tools for automating more of the checks?

Having strong contextual documentation about the overall project definitely helps a lot. Our chief architect created the manifest, which has all the guard rails and is something that we have the AI coders read prior to writing any code. He even created a council that the vibe coder runs after every session that checks all the code, comes to a consensus, flags things that really need to be changed versus opinion, which has also been a great addition. The bottleneck, though, is still in the PR and merge process because we're able to get new features coded pretty quickly, but then they are dependent on a person that has a lot of other responsibilities. I've heard of a few different apps that can really help get through the PR and merge process faster. Not sure if any of them are any good. But ultimately, probably just going to hire a dedicated team member that does the PR review and merging as the gatekeeper.
