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 package is a Linux ARM64 CLI distribution with no lifecycle hooks or JavaScript entry point declared in its manifest. The inspected routing leads are consistent with GitHub URL handling, official CLI setup commands, and the Cursor SDK’s own telemetry; no unrelated credential transfer or other attack behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 83.0% - **Started:** 2026-11-01T19:48:08.543Z - **Finished:** 2026-11-01T19:53:26.907Z - **Download time:** 79210 ms - **Static scan time:** 46418 ms - **AI review time:** 192736 ms - **Total time:** 318364 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 in the inspected package source. - **Trigger:** No install hook or automatic JavaScript entry point is declared in the root manifest. - **Impact:** No malicious impact was established from the reviewed source. - **Review source:** ai\_review - **Reviewed:** 2026-11-01T19:53:26.907Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The reviewed network and command references serve CLI setup, GitHub file URL handling, or Cursor SDK events; no credential forwarding to an unrelated host was established. - **Rationale:** The package is a Linux ARM64 CLI distribution with no lifecycle hooks or JavaScript entry point declared in its manifest. The inspected routing leads are consistent with GitHub URL handling, official CLI setup commands, and the Cursor SDK’s own telemetry; no unrelated credential transfer or other attack behavior was found. ### Review decision - **Verdict:** Clean - **Confidence:** 83.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest describes a Linux ARM64 CLI package and lists its binary, client assets, and dependencies., The root manifest contains no lifecycle scripts or JavaScript entry-point declarations., The setup UI contains installer commands for Claude and Codex from their official hosts., The GitHub-related asset code restricts supported URLs to GitHub hosts and handles them as file URLs., The Cursor SDK sends events to its own backend and includes SDK version and platform fields. ## Affected versions and remediation This report applies to @s2code/t3-linux-arm64@0.1.5-nightly.20261101.79. - Review the evidence and your use of @s2code/t3-linux-arm64@0.1.5-nightly.20261101.79 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.
