The CLI’s target-site requests match its auditing purpose, but it also silently sends the full target URL and audit results to AnswerRail. That undisclosed runtime telemetry makes the package suspicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-31T18:04:07.104Z - **Finished:** 2026-10-31T18:04:40.921Z - **Download time:** 256 ms - **Static scan time:** 223 ms - **AI review time:** 33338 ms - **Total time:** 33817 ms The recorded confidence comes from the underlying analysis.
