sigil-scan

SUSPICIOUS: the overall purpose is coherent for a security-audit skill, and the credential-file access is plausibly necessary for environment auditing. However, the skill relies on unprovided shell scripts, references sensitive local files, and has mixed installer/package-name provenance across official-looking sources, so trust and data-flow clarity are incomplete.

The code is primarily benign CLI support logic, but the Python fallback in merge_scan_json contains a code-injection vulnerability when target is untrusted. Use JSON serialization or pass the value through stdin/environment rather than interpolating it into Python source. No clear malware behavior is present.
