## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 18 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 2.4.3
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

Installing this package does not run setup or network code. Runtime work is a user-run design-audit CLI; optional Pulse uplink and LLM calls need explicit configuration and user keys, and --setup only installs this tool's own agent instructions.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 88.0%
- **Started:** 2026-09-18T22:40:11.300Z

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:** Installing this package does not run setup or network code. Runtime work is a user-run design-audit CLI; optional Pulse uplink and LLM calls need explicit configuration and user keys, and --setup only installs this tool's own agent instructions.

- **Trigger:** The user runs the designcheck command, optionally with --setup, --pulse, --llm, or --vision.

- **Impact:** No unconsented install-time mutation, credential theft, or hidden exfiltration was found.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-18T22:44:46.572Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** User-invoked design audit CLI with optional first-party agent skill install

- **Rationale:** The published manifest has no install-time hooks, and remaining network, WASM, and agent-setup behavior is user-invoked and matches a licensed design-audit CLI. Scanner malware-similarity and host-exfil labels track an unwired leftover postinstall helper plus optional Pulse finding uplink, not a concrete attack.

### Review decision

- **Verdict:** Clean

- **Confidence:** 88.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The published package.json exposes the designcheck CLI and dist/ files; its scripts are check, test, build, prepack, and bench, with no preinstall, install, or postinstall hook., Agent files are written only when the user runs designcheck --setup, which installs this package's own Claude skill plus optional Cursor and Codex instructions., Pulse telemetry and context packets stay off unless NAVIAN\_PULSE\_URL or --pulse is set, and then findings go to that operator URL., self-audit.js only counts which in-engine audit functions and checks ran; it does not harvest host identity or open a network connection., webview-cdp.js talks to a user-supplied local Chrome DevTools endpoint to inject the same in-page auditor., Optional vision and LLM calls send the caller's API key to Anthropic, OpenAI, or Gemini, the intended model services.

- **Evidence against:** Nested dist/package.json still declares postinstall, and dist/bin/postinstall.js would auto-install the Claude skill if that leftover script were executed., designcheck --setup writes into ~/.claude/skills/designcheck, .cursor/rules, and AGENTS.md., License corpus loading uses Function() on decrypted blob text, and the package ships WASM modules for the auditor and license key derivation., Static scanner similarity to an earlier blocked release remains, but that release used an automatic postinstall this version removed.
