🟢 Trusted
No high-risk patterns surfaced by the deep scan — automated capability review, not behavioral proof.

Skill searches PubMed via the free official E-utilities API; the .env file reference is for optional NCBI API key configuration, not credential exfiltration, and all operations target the official PubMed service.

⚠ Flagged for review — coarse, uncorroborated signal, not a confirmed exploit. Review the config yourself before installing.

Automated static analysis — not a human review. Caveat flags capabilities, not confirmed intent, and can produce false positives. Disagree with this verdict? Use Dispute below.
