## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 16 low-signal pattern(s) reviewed.

- **Verdict:** Manual Review
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Under Review
- **Threat category:** Unknown
- **Selected version:** 0.0.0-alpha.33
- **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: manual review; recommendation: manual review. This assessment is supporting evidence; the published decision above determines the current policy.

The scanner's command execution and network indicators are consistent with browser launch, process management, and configurable telemetry in the inspected excerpts. Because the declared Playwright dependency source could not be resolved, its behavior remains unverified and warrants manual review.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Manual Review
- **Recorded analysis confidence:** 69.0%
- **Started:** 2026-10-22T06:27:40.664Z

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 concrete attack was established in the inspected package source. The unresolved Playwright dependency leaves part of the runtime behavior unverified.

- **Trigger:** Using the package runtime and its browser automation functions.

- **Impact:** No malicious impact was confirmed; unresolved dependency behavior prevents a clean determination.

- **Evidence paths:** package.json, dist/index.cjs, dist/index.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-10-22T06:28:59.614Z

### AI review details

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

- **Mechanism:** The package imports Playwright and launches browser processes; inspected output capture is referenced in the browser startup-failure path.

- **Rationale:** The scanner's command execution and network indicators are consistent with browser launch, process management, and configurable telemetry in the inspected excerpts. Because the declared Playwright dependency source could not be resolved, its behavior remains unverified and warrants manual review.

### Review decision

- **Verdict:** Manual Review

- **Confidence:** 69.0%

- **Recommended action:** manual\_review

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **AI review observations:** The package exposes CommonJS and ESM runtime entrypoints and declares Playwright as a runtime dependency., The CommonJS entrypoint imports Playwright; the reviewed process-output capture is used in a browser startup-failure path., Telemetry endpoints and enablement are read from environment configuration; no unrelated recipient was established in the inspected excerpts., Playwright dependency source remains unresolved in the available snapshot, so its runtime behavior could not be verified.

- **Evidence against:** The manifest lists build and development scripts, with no install lifecycle hook shown., The inspected runtime operation checks a browser-launch request and binds it to the current profile.

## Affected versions and remediation

This report applies to @agimon-ai/po-browse-tool@0.0.0-alpha.33.

- Review the evidence and your use of @agimon-ai/po-browse-tool@0.0.0-alpha.33 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.
