## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 15 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:** 0.0.0-alpha.4
- **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 manifest has no install lifecycle hook, and the inspected runtime behavior is consistent with browser automation and browser setup. Static flags for process output and networking did not establish an unrelated data transfer or other attack.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Clean
- **Recorded analysis confidence:** 94.0%
- **Started:** 2026-10-17T09:14:33.703Z
- **Finished:** 2026-10-17T09:17:21.012Z
- **Download time:** 1015 ms
- **Static scan time:** 2022 ms
- **AI review time:** 164271 ms
- **Total time:** 167309 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:** No attack was identified in the inspected source. The flagged command-output handling supports browser startup diagnostics, and the network calls inspected support browser automation and Chrome setup.

- **Trigger:** Using the browser runtime or starting its extension browser.

- **Impact:** No unrelated data disclosure, unauthorized account action, or other confirmed attack impact was identified.

- **Review source:** ai\_review

- **Reviewed:** 2026-10-17T09:17:21.012Z

### AI review details

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

- **Mechanism:** The runtime launches a browser for the bound profile, communicates browser tool calls to its configured execution endpoint, and retrieves Chrome version metadata from Google's feed.

- **Rationale:** The manifest has no install lifecycle hook, and the inspected runtime behavior is consistent with browser automation and browser setup. Static flags for process output and networking did not establish an unrelated data transfer or other attack.

- **Network endpoints:** https://googlechromelabs.github.io/chrome-for-testing/known-good-versions-with-downloads.json

### Review decision

- **Verdict:** Clean

- **Confidence:** 94.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence for AI clean decision:** package.json lists development and build scripts, with no install lifecycle hook; its entrypoints are the CLI and runtime modules., Both runtime entrypoints restrict browser launch to the bound profile and browser type., The Chrome installer requests version metadata from Google's Chrome for Testing feed and uses a cache for the browser executable., The extension browser code captures child-process output and uses it in a browser startup failure diagnostic., The extension bridge sends selected browser tool calls and their arguments to its configured execution endpoint.

- **Evidence against:** The flagged command-output behavior is tied to browser startup diagnostics; the inspected code does not show it sending captured output to an unrelated recipient.

## Affected versions and remediation

This report applies to @agimon-ai/po-browse-tool@0.0.0-alpha.4.
