GitHub PR Bot
Auto-scan every pull request for slopsquatted packages

Install once. DevHorrors automatically comments on PRs that introduce malicious dependencies, sets commit statuses, and breaks builds on critical threats — powered by both our encyclopedia and AI hallucination detection.

DevHorrors authenticates to GitHub through an authorized connector with repo and workflow scopes — no long-lived tokens or secrets to manage. The bot reads changed manifest files, runs the scan, then posts a PR comment and a commit status.

Connector: github · scopes: repo, workflow
Auto-blocking & repo-wide scanning are available on the Exorcist plan. View plans →
