I was inspired by mitchellh's Vouch project, an explicit trust system where maintainers vouch for contributors before they can interact with a repo. Ghostty uses it to filter out AI slop PRs.

Because Vouch exposes the vouch list as a plain text file (VOUCHED.td), I realized I could aggregate them across GitHub and build a reputation index. A crawler finds every VOUCHED.td file, pulls the entries, and computes a weighted score per user. Vouches from high-star repos count more than vouches from zero-star repos.

Next step is to wire up an API so that the vouch GH action can start to use this data to auto approve contributors.
