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 did not substantiate the scanner's malicious verdict. The manifest has no npm install hook, and the inspected flagged code shows ordinary CLI and agent-skill functionality. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-19T11:55:29.912Z - **Finished:** 2026-10-19T11:56:19.579Z - **Download time:** 766 ms - **Static scan time:** 2298 ms - **AI review time:** 46603 ms - **Total time:** 49667 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 surface was identified in the inspected source. The flagged agent-related code concerns project instructions and skill directories. - **Trigger:** The inspected agent-related behavior is associated with CLI setup or skill operations; no npm install trigger was found. - **Impact:** No confirmed malicious effect was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-19T11:56:19.579Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The manifest's prepublishOnly script runs a clean and build. The inspected runtime offsets resolve to logging, WebSocket, device, skill, and debugging code. - **Rationale:** Source inspection did not substantiate the scanner's malicious verdict. The manifest has no npm install hook, and the inspected flagged code shows ordinary CLI and agent-skill functionality. ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json defines only a prepublishOnly build-and-clean lifecycle script; it has no npm install hook., The account-action byte locations in build/cli/index.js are local log-segment rotation and session logging code., The flagged agent files concern managed AGENTS.md instructions and agent skill directories., The other flagged bundles contain device, skill, WebSocket, and runtime-error tooling; the inspected excerpts show no attack behavior. ## Affected versions and remediation This report applies to @expo/agent-cli@1.0.13. - Review the evidence and your use of @expo/agent-cli@1.0.13 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.
