The answer is you can’t. Repo activity isn’t a real way to measure anything about a person’s ability. The only reasonable thing is to hire and do 3-month probation period.

You call tech hiring "broken." Have you considered that trying to reduce programmer skill and value to a simple formula or metric contributes to that? Perhaps the swipe left or right mentality of "tech recruiting," adapted from the also broken dating domain has something to do with it. Recruiters and hiring managers unqualified to talk to and evaluate candidates hiding behind CYA tools -- broken.

Tech hiring does indeed look broken for people who only have their git history to sell themselves.

No employer or customer I have ever worked for would give access to their private repos for data collection. A candidate who did give such access likely broke their NDA and maybe the law. I have no public git repos, consistent with many of the professional programmers and freelancers I know. I only work in private repos owned by a company that has the resources to enforce their IP. Curious how you can assert in comments that your tool analyzes private repos.
