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’s postinstall hook only adjusts permissions on known node-pty helper binaries. Reviewed agent cleanup, login, upgrade, host, and screen behaviors align with the package’s remote terminal bridge; no concrete attack behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-10T01:03:45.252Z - **Finished:** 2026-10-10T01:04:22.040Z - **Download time:** 2062 ms - **Static scan time:** 2745 ms - **AI review time:** 31980 ms - **Total time:** 36788 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 source. The install hook adjusts permissions on node-pty helpers, and the inspected runtime behaviors fit the remote terminal bridge. - **Trigger:** Package installation runs the postinstall hook; login, upgrade, host, and screen operations require their respective commands or runtime use. - **Impact:** No concrete malicious impact was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T01:04:22.040Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The install hook changes helper permissions. The inspected agent cleanup targets LinkShell hook entries, while login uses a loopback callback and host features perform local terminal and screen operations. - **Rationale:** The manifest’s postinstall hook only adjusts permissions on known node-pty helper binaries. Reviewed agent cleanup, login, upgrade, host, and screen behaviors align with the package’s remote terminal bridge; no concrete attack behavior was found. ### Review decision - **Verdict:** Clean - **Confidence:** 88.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook resolves the installed node-pty helper and adjusts permissions on known platform binaries., Hook cleanup matches LinkShell hook entries and sweeps known agent settings files; the inspected target code also reads Claude project storage., Login binds its callback server to 127.0.0.1, and the upgrade command installs a newer linkshell-cli release only when run., Host and screen code perform local listener discovery and screen capture for the remote terminal bridge., The Claude driver documents a desktop-to-device session handoff through its ACP adapter. ## Affected versions and remediation This report applies to linkshell-cli@0.6.2. - Review the evidence and your use of linkshell-cli@0.6.2 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.
