Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The external POST is package-aligned SDK telemetry to the vendor API, and the manifest has no install-time lifecycle hook. The inspected source does not establish an attack surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-08T16:26:31.890Z - **Finished:** 2026-10-08T16:27:02.126Z - **Download time:** 763 ms - **Static scan time:** 3476 ms - **AI review time:** 25995 ms - **Total time:** 30236 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No attack was identified. The flagged network behavior is telemetry sent to the package vendor’s SDK endpoint. - **Trigger:** The client library queues telemetry events during use and flushes them periodically or when the event threshold is reached. - **Impact:** No confirmed credential theft or unrelated data forwarding was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-08T16:27:02.126Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It POSTs queued events with its SDK token to the vendor API telemetry path; the ordinary request omits browser credentials. - **Rationale:** The external POST is package-aligned SDK telemetry to the vendor API, and the manifest has no install-time lifecycle hook. The inspected source does not establish an attack surface. - **Network endpoints:** https://api.arcyai.com/api/v1/sdk/telemetry ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest exposes a bundled library entrypoint and has only a prepublishOnly build hook, with no install-time hook., The flagged POST sends queued events with a bearer token to the SDK telemetry endpoint at the vendor API host. ## Affected versions and remediation This report applies to arcy.js@0.2.6. - Review the evidence and your use of arcy.js@0.2.6 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
