Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 15 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 1.0.16 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 manifest has no npm install lifecycle hook, and the flagged agent configuration changes are gated by an explicit setup command and confirmation. The inspected runtime excerpts show ordinary CLI, device, WebSocket, and logging behavior, with no concrete attack identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-19T11:55:30.112Z - **Finished:** 2026-10-19T11:57:02.033Z - **Download time:** 251 ms - **Static scan time:** 2578 ms - **AI review time:** 89091 ms - **Total time:** 91921 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 behavior was identified in the inspected source. Agent setup is an explicit CLI action that applies selected skill or instruction setup after confirmation. - **Trigger:** A user runs agents:setup and confirms the selected plan, or explicitly passes --yes. - **Impact:** No confirmed attack surface; the inspected changes are user-requested setup. - **Review source:** ai\_review - **Reviewed:** 2026-10-19T11:57:02.033Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Setup can install selected agent skills or plugins and update a managed block in the project’s AGENTS.md. No install-time trigger or unrequested credential or account action was identified. - **Rationale:** The manifest has no npm install lifecycle hook, and the flagged agent configuration changes are gated by an explicit setup command and confirmation. The inspected runtime excerpts show ordinary CLI, device, WebSocket, and logging behavior, with no concrete attack identified. ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has no npm install lifecycle hook; its prepublishOnly script runs the clean and production build commands., Agent setup requires confirmation unless the user explicitly passes --yes, and setup returns without applying changes when the plan is unconfirmed., The managed instruction block is written to the project’s AGENTS.md; setup also exposes this work as an explicit agents:setup command., Agent skills use conventional project or user skill directories, and the setup plan selects supported agents and destinations., Inspected runtime code handles local device screenshots, WebSocket headers, and local event logging; these excerpts show no unrequested account action or credential transfer., Other flagged behavior is ordinary CLI handling: missing Expo is reported with an install suggestion, and device probing determines whether a local device is available. ## Affected versions and remediation This report applies to @expo/agent-cli@1.0.16. - Review the evidence and your use of @expo/agent-cli@1.0.16 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.
