Caveat verdict

fabric-cli

88
🟢 Trusted
No high-risk patterns surfaced by the deep scan — automated capability review, not behavioral proof.

Wraps the fabric.so CLI for personal knowledge-management operations with explicit consent and safety rules for write operations; the execution sink is the expected CLI invocation pattern for its stated purpose.

⚠ 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.
