Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 15 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.48 - **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 inspected package source shows browser operations and startup diagnostics, with telemetry gated by configuration. Because selected runtime dependency sources were unavailable for review, the remaining behavior is unresolved and requires manual review. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-25T05:58:52.582Z - **Finished:** 2026-10-25T06:00:07.715Z - **Download time:** 2066 ms - **Static scan time:** 1632 ms - **AI review time:** 71435 ms - **Total time:** 75133 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 concrete attack was identified in the inspected package source. Some selected runtime dependency implementations remain unreviewed. - **Trigger:** Importing the package loads its declared runtime dependencies. - **Impact:** No attack is established, but the incomplete dependency review prevents a clean verdict. - **Review source:** ai\_review - **Reviewed:** 2026-10-25T06:00:07.715Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The available source shows browser automation and configurable telemetry; the behavior of some imported dependencies could not be confirmed. - **Rationale:** The inspected package source shows browser operations and startup diagnostics, with telemetry gated by configuration. Because selected runtime dependency sources were unavailable for review, the remaining behavior is unresolved and requires manual review. - **Files touched:** package.json, dist/index.cjs, dist/extension/background.js ### Review decision - **Verdict:** Manual Review - **Confidence:** 84.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The manifest lists build and development scripts but no npm install lifecycle hook., The runtime imports registry dependencies declared in the manifest; some selected dependency implementations were not available for source review., The browser operation handler checks the requested operation and binds launches to the configured profile and browser., The browser code tool accepts code supplied by its caller or a saved snippet., Browser process output is captured for startup diagnostics and passed to a failure log when the extension does not become ready., Extension telemetry starts disabled, and sending spans requires an enabled configuration and a configured endpoint. ## Affected versions and remediation This report applies to @agimon-ai/po-browse-tool@0.0.0-alpha.48. - Review the evidence and your use of @agimon-ai/po-browse-tool@0.0.0-alpha.48 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. ## Public findings ### 1.
