Hidden instructions in HTML comments
HTML comment blocks are invisible to human readers but parsed by AI agents that process HTML files. Malicious instructions hidden in comments in documentation or templates can hijack an agent's behaviour during a coding session.
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 AI Agent 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.
