Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 17 low-signal pattern(s) reviewed. - **Verdict:** Manual Review - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Under Review - **Threat category:** Unknown - **Selected version:** 0.6.4 - **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy. Inspection found package-aligned screen capture, port discovery, authentication, and upgrade behavior, alongside a runtime agent-settings sweep whose effective scope and caller consent were not established. Relevant static analysis also reports parse errors, so a clean or malicious conclusion is not supported by the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 66.0% - **Started:** 2026-10-10T01:04:48.691Z - **Finished:** 2026-10-10T01:06:07.303Z - **Download time:** 1273 ms - **Static scan time:** 2781 ms - **AI review time:** 74557 ms - **Total time:** 78612 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 concrete attack was established from the inspected excerpts. A runtime hook sweep writes agent settings files, but its exact filtering and caller behavior remain unresolved. - **Trigger:** The package has a postinstall hook; the settings sweep is part of runtime hook handling, but its activation path was not established here. - **Impact:** Potential agent configuration changes remain unresolved; the evidence does not establish credential theft or another confirmed attack. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T01:06:07.303Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The sweep reads hook configuration and may write updated JSON when changes are found. The available excerpt does not show which entries are removed. - **Rationale:** Inspection found package-aligned screen capture, port discovery, authentication, and upgrade behavior, alongside a runtime agent-settings sweep whose effective scope and caller consent were not established. Relevant static analysis also reports parse errors, so a clean or malicious conclusion is not supported by the inspected source. - **Files touched:** package.json, src/runtime/hook-command.ts, dist/cli/src/runtime/hook-command.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 66.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** package.json defines a postinstall hook that runs scripts/postinstall.mjs., The hook-command implementations enumerate Claude, Codex, and Gemini settings files; the source implementation parses hook entries and writes a file only when its sweep reports a change., The Claude SDK code uses the Claude projects directory for project data., The screen fallback captures a local screen image; the ports utility enumerates listening ports., Login and upgrade contain service-authentication and package-upgrade behavior, while the cited host code handles environment selection. - **Evidence against:** The runtime hook sweep writes agent settings files, and the inspected excerpt does not establish the exact filter or caller consent., Static analysis reports parse errors in relevant source files, leaving the complete behavior unresolved. ## Affected versions and remediation This report applies to linkshell-cli@0.6.4. - Review the evidence and your use of linkshell-cli@0.6.4 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.
