Yep - we do exactly the same with Claude. In fact - part of our PR review automation with Claude includes checking whether the PR is tightly scoped or should be split apart. I’d say in about 80% of the cases the Claude review bot is accurate in its assessment to break it up? It’s optional feedback but useful - especially when we get contributors outside our immediate team that maybe don’t know our PR norms and the kinds of things we typically aim for.

Yeah I usually default to just a straight up link or a markdown link. Mostly because I usually don’t know the exact number of a PR/ticket/issue - so it’s easy to just copy the URL once I’ve found it.
