## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 12 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:** 0.18.49
- **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.

The postinstall command performs ordinary Playwright browser setup. Network access occurs through library documentation-fetching APIs, with no inspected source behavior establishing credential theft, unrelated data disclosure, or destructive activity.

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 attack was identified. The install hook sets up Playwright’s Chromium browser, and runtime network requests support documentation retrieval.

- **Trigger:** Package installation runs the postinstall hook; a consumer calls the documentation synchronization API to fetch sources.

- **Impact:** The inspected behavior is consistent with browser setup and documentation ingestion; no concrete attack behavior was established.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-13T04:35:37.304Z

### AI review details

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

- **Mechanism:** The hook invokes Playwright’s browser installer. Synchronization retrieves registered documentation URLs or queries Context7 and configured GitHub repositories.

- **Rationale:** The postinstall command performs ordinary Playwright browser setup. Network access occurs through library documentation-fetching APIs, with no inspected source behavior establishing credential theft, unrelated data disclosure, or destructive activity.

- **Network endpoints:** https://context7.com/api/v2/context, https://github.com

### Review decision

- **Verdict:** Clean

- **Confidence:** 92.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** The only install hook runs Playwright’s Chromium installer., The entrypoint exports the knowledge engine and fetch helpers as library APIs., Document synchronization fetches registered source URLs when called., The additional network requests retrieve documentation from Context7 and configured GitHub repositories.
