Contributors box on repo main page still shows a contributor that main doesn’t contain

Bug

Body

My repository’s main page shows “Contributors 2” including “claude”, more than two weeks after I rewrote the history. Insights → Contributors shows only me (223 commits, and the weekly bars add up to 223), and git log origin/main has no committer, author or trailer for that account. I suspect the sidebar’s contributor cache is stale. Is there a way to make GitHub rebuild it?

Your diagnosis is right. I found the repo (CNN-Malaria-Detection-System), and its homepage data (/_sidebar) still reports contributorCount: 2 with claude. Meanwhile /contributors lists only you (224 commits), and there are no other branches, tags or pull requests that could still contain the old commits.

Where the entry comes from. The force push to main on Oct 20 at 17:06 UTC replaced 8 commits from 16:43–16:55 UTC that day (fc65602a … 521f59b9). Each had a Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com> trailer, and GitHub links that email to the claude account. The Contributors box on the homepage is cached separately and isn't recalculated after a force push. Your later pushes (Oct 29 to Nov 10) didn't trigger a recount either, which is why it's still there after three weeks.

How to make GitHub rebuild it: switch the default branch away and back. Your repo only has main, so create a temporary branch first:

1. git push origin main:tmp
2. Settings → General → Default branch: switch to tmp.
3. Open the repository homepage once, wait a couple of minutes, then switch the default branch back to main.
4. Delete tmp (git push origin --delete tmp).

This is the same sequence that fixed a single-branch repo in #212678 yesterday. If claude is still listed a day later, only GitHub can purge the cache. #204093 collects reports of this exact issue.

To keep the trailer out of future commits, add this to Claude Code's settings.json. Use ~/.claude/settings.json for all projects, or .claude/settings.json for just this repo:

{
  "attribution": { "commit": "", "pr": "" }
}

The older includeCoAuthoredBy setting is deprecated, so use attribution instead. See the settings reference.
