Anti-Slop GitHub Action blocks AI-generated PRs

The OSS AI slop crisis just got its first real countermeasure — and it's more sophisticated than anyone expected.

• –The honeypot check is particularly clever: invisible HTML comments in PR templates instruct LLMs to include a specific word, which humans never see but AI agents following raw markdown do
• –The `min-global-merge-ratio` check (minimum 30% merged/closed ratio across all of GitHub) is flagged by the author as "one of the most effective" — AI-powered accounts tend to close more PRs than they merge
• –`max-daily-forks` (max 7 in 24h) targets automated mass-forking patterns that precede bulk PR campaigns
• –The tool is explicitly framed as "anti-slop, not anti-AI" — well-written AI-assisted PRs that follow project norms should pass all checks
• –Context matters: curl maintainer Daniel Stenberg noted useful bug reports dropped from 15% to 5% of submissions after AI flooding; Godot maintainers called it "demoralizing"
