Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-08T12:07:10.117Z - **Finished:** 2026-09-08T12:08:12.600Z - **Download time:** 253 ms - **Static scan time:** 115 ms - **AI review time:** 62113 ms - **Total time:** 62483 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:** An explicit CLI installation can add Claude Code hooks in the user's home configuration. Those hooks inspect local state and send command-verification data to a remote service. - **Trigger:** The user runs the package's --install command, then uses Claude Code. - **Impact:** A remote service can influence agent decisions and receive command-related or local-environment data for each hooked event. - **Evidence paths:** dist/index.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-08T12:08:12.600Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Claude hook installation with remote command verification and prompt-context injection. - **Rationale:** This is an explicit-user-command agent configuration tool rather than an automatic install-time attack. Its obfuscation and persistent remote-controlled hook capability warrant a warning. - **Files touched:** ~/.claude/settings.json, ~/.check/key - **Network endpoints:** https://triage.golproductions.com/preflight ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The published executable is heavily obfuscated and combines filesystem writes, process spawning, environment access, and network requests., Its explicit install flow configures Claude Code hooks in the user's home configuration., The installed prompt hook is described as reading local machine state and injecting a standing rule into every prompt., The hook sends command-verification requests to the vendor endpoint. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The risky configuration path is activated by an explicit --install command, not automatically on npm installation., No runtime dependency or lifecycle self-dependency is declared. ## Affected versions and remediation This report applies to @golproductions/check@4.1.7. - Review the evidence and your use of @golproductions/check@4.1.7 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.
