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:** 80.0% - **Started:** 2026-09-18T22:47:52.914Z - **Finished:** 2026-09-18T22:52:49.546Z - **Download time:** 255 ms - **Static scan time:** 635 ms - **AI review time:** 295741 ms - **Total time:** 296632 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:** There is no npm install hook. If a user runs designcheck --setup, the CLI writes first-party instructions into Claude Code skills, a Cursor rule file, and Codex AGENTS.md so those agents will call this auditor. Scanner malware-similarity and host-fingerprint labels do not show a hidden exfil path. - **Trigger:** User or agent runs designcheck --setup (including the README install sequence). - **Impact:** Coding agents in that environment start following packaged UI-audit instructions and invoking the designcheck CLI. - **Evidence paths:** dist/lib/setup.js, dist/docs/USER-MANUAL-IDE.md, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-18T22:52:49.546Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Explicit user-command write of first-party Claude, Cursor, and Codex instruction files - **Rationale:** Source has no npm install hook; agent config is written only when the user runs designcheck --setup, which copies first-party Claude, Cursor, and Codex instructions. Scanner malware-similarity and host-fingerprint hits are noisy: telemetry is Pulse-opt-in and this tree does not harvest host identity for a hidden endpoint. - **Files touched:** ~/.claude/skills/designcheck/SKILL.md, ~/.claude/skills/designcheck/designcheck.js, .cursor/rules/designcheck.md, AGENTS.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 80.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** designcheck --setup copies SKILL.md and designcheck.js into the Claude Code skills directory under the user home folder., The same setup writes .cursor/rules/designcheck.md and creates or appends AGENTS.md in the current project., README lists npx designcheck --setup as a normal install step, so users and agents are steered to run it., setup.js exports installClaudeSkill, installCursorRule, and installCodexAgents as the implementation of that command. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle scripts; the published bin is a user-run CLI., Changelog says the postinstall hook was removed and agent wiring is opt-in through --setup., Pulse/telemetry uplink is off unless NAVIAN\_PULSE\_URL or --pulse is set; --no-telemetry forces it off., Network hosts are official LLM APIs with caller keys, a user Pulse URL defaulting to 127.0.0.1, or the page under audit., child\_process use is git rev-parse and an optional local uiclip runner; self-audit is local coverage reporting, not host identity theft. ## Affected versions and remediation This report applies to @navianpulse/designcheck@2.4.5. - Review the evidence and your use of @navianpulse/designcheck@2.4.5 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.
