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 Injection 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.
