## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 17 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:** 2.4.6
- **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.

Install does not run package code. Remaining network, process, WASM, and agent-file behavior is the designcheck CLI: Pulse only when configured, LLM keys to their vendor APIs, git/uiclip execFile, and first-party --setup.

## Security analysis

### Published attack-surface review

- **Summary:** Install does not run package code. Remaining network, process, WASM, and agent-file behavior is the designcheck CLI: Pulse only when configured, LLM keys to their vendor APIs, git/uiclip execFile, and first-party --setup.

- **Trigger:** npm install does not execute this package; optional behavior runs only if a user executes the designcheck CLI.

- **Impact:** No install-time or import-time attack is established.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-18T23:09:44.268Z

### AI review details

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

- **Mechanism:** No confirmed covert collection or unconsented agent-control write.

- **Rationale:** The published tarball has no install lifecycle hooks. Scanner hits for host fingerprinting, child\_process, WASM, and prior-malware similarity describe a user-run design-audit CLI with opt-in Pulse, official LLM APIs, and explicit --setup, not an attack.

### Review decision

- **Verdict:** Clean

- **Confidence:** 86.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json ships only a CLI bin and dist/ files; scripts are check, test, build, and prepack with no preinstall, install, or postinstall hook., The designcheck CLI talks to Pulse only when --pulse or NAVIAN\_PULSE\_URL is set; gather mode exits if no Pulse server is configured., context-packet.js is a Pulse client that optionally reads git HEAD and fetches a rule packet from the configured Pulse URL., self-audit.js only compares expected audit functions and checks against what ran and formats a coverage report., webview-cdp.js injects this package's designcheck engine into a user-supplied CDP WebView and runs audit()., Changelog records that the old postinstall hook was removed and agent files install only via designcheck --setup.

- **Evidence against:** A prior release of this product used a postinstall hook, which is why static similarity to a blocked package is noisy rather than proof., designcheck --setup can write first-party Claude, Cursor, and Codex instruction files, but only when the user runs that command., Optional --llm/--vision paths send screenshots to api.anthropic.com, api.openai.com, or generativelanguage.googleapis.com using caller-supplied keys.

## Affected versions and remediation
