Caveat verdict

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

Receives external input AND executes processes

Implements a file-based inter-agent communication system using shared local directories; file read/traversal capabilities are used legitimately for reading and writing mailbox messages with no external data exfiltration.

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.
