I think the related files could be useful for ai agents. I recently wrote a CLI that an agent can pass in files and get back additional ones. Don't have enough data to see if it has materially changed performance i.e. finding extra files that it would have missed

On the trends page, for some repos, you can see that the velocity hasn't materially went up, at least as a function of merged PRs (not that it is the only unit of value). But if you look at posthog, they seem to be crushing it and have a significant jump in merged PRs in the last few months
