SlopGuard - AI PR Quality Filter

GitHub app that automatically flags and quarantines low-quality or AI-generated pull requests and issues before they clutter your repository. Saves developers time reviewing junk submissions.

The signal-to-noise problem in open source repos has gotten meaningfully worse since 2023, as AI coding tools made it trivially easy to generate and submit low-effort PRs at scale — maintainers on Reddit and GitHub Discussions have been vocal about the fatigue. No clear incumbent owns this specific filtering layer, though Mergify handles workflow automation and could theoretically expand here. The $1k–5k/mo band is plausible for a GitHub Marketplace app with per-seat or per-repo pricing, since the pain is real but the buyer is often an individual maintainer or small team with limited willingness to pay. The biggest risk is that GitHub itself ships a native quality filter, which is exactly the kind of housekeeping feature they've been quietly adding to the platform.
