Committed git hooks with shell execution (post-checkout, post-merge)
Git hooks committed to a repository execute automatically on clone, checkout, or merge without user confirmation. A post-checkout hook can silently run arbitrary code the moment a developer clones or opens the repo in an AI coding environment.
HOW VIBECHECK DETECTS THIS
vibecheck clones your repository and runs Gitleaks, Semgrep, njsscan, and a suite of custom checks targeting patterns common in AI-generated code. This check is part of the Repository Trust category. When a matching pattern is found, Claude triages the finding and produces a plain-English explanation and a concrete fix — no security expertise required.
