gray-matter

No clear malware/backdoor behavior is evident in the shown code (no eval, no network activity, no OS command execution derived from user input beyond a hard-coded install). The primary security concern is supply-chain/install-time risk: if gray-matter is missing, the script runs `npm install gray-matter` at runtime (without version pinning or integrity verification) and then executes that dependency code via require. Additionally, the tool can output parsed front-matter/content to stdout, which may expose sensitive data if invoked on confidential inputs in an unsafe pipeline.
