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. Source inspection found vendor-directed runtime event reporting and a prepublish build hook, but no install-time attack, credential harvesting, or unrelated recipient. The scanner’s declaration-file finding points to type documentation rather than executable code. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-07T22:07:51.998Z - **Finished:** 2026-10-07T22:08:20.590Z - **Download time:** 2536 ms - **Static scan time:** 3133 ms - **AI review time:** 22922 ms - **Total time:** 28592 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 malicious attack was identified. The inspected runtime contains event reporting to the package vendor API as part of its user-facing SDK behavior. - **Trigger:** Application code invokes the SDK reporter and supplies a fetch implementation and API token. - **Impact:** This supports SDK event reporting, with no inspected evidence of unrelated credential exposure or install-time compromise. - **Review source:** ai\_review - **Reviewed:** 2026-10-07T22:08:20.590Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The reporter posts event tool and name data to the configured API base; the bundled default is api.arcyai.com. - **Rationale:** Source inspection found vendor-directed runtime event reporting and a prepublish build hook, but no install-time attack, credential harvesting, or unrelated recipient. The scanner’s declaration-file finding points to type documentation rather than executable code. - **Network endpoints:** https://api.arcyai.com ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest has a prepublishOnly build hook and no install-time lifecycle hook., The seen-event reporter posts tool and name data through an injected fetch function to an API base; the bundled default is api.arcyai.com., The flagged design-mode file is a TypeScript declaration describing an event fingerprint, not executable behavior. - **Evidence against:** No inspected source showed an install-time mutation, secret harvesting, or a package-controlled unrelated network recipient. ## Affected versions and remediation This report applies to arcy.js@0.1.17. - Review the evidence and your use of arcy.js@0.1.17 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.
