Caveat verdict

rtk-compress

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

Token-optimization CLI wrapper (rtk) for compressing shell command output before it reaches LLM context; installs via brew or a documented install script from a named GitHub repo, all behavior matches the stated purpose of reducing token usage.

⚠ 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.
