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. Source inspection found the flagged process handling serves browser management and local failure diagnostics, with no confirmed exfiltration path. The manifest has no install lifecycle hook. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-20T01:31:56.795Z - **Finished:** 2026-10-20T01:33:03.168Z - **Download time:** 765 ms - **Static scan time:** 1635 ms - **AI review time:** 63971 ms - **Total time:** 66373 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 runtime paths. The flagged process output is captured for browser startup diagnostics and written to a local temporary log on failure. - **Trigger:** Browser launch through the package runtime; the diagnostic log is written only if startup fails and output exists. - **Impact:** No command output exfiltration or other confirmed attack impact was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-20T01:33:03.168Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Browser operations are bound to the runtime's registered page; captured process output is stored locally. - **Rationale:** Source inspection found the flagged process handling serves browser management and local failure diagnostics, with no confirmed exfiltration path. The manifest has no install lifecycle hook. - **Files touched:** dist/index.cjs, dist/index.mjs ### 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 points to the inspected CommonJS and ESM runtime entrypoints., package.json has no install lifecycle hook., The CommonJS runtime bounds captured browser output and saves a launch log locally on failure., The CommonJS and ESM runtimes verify that a page belongs to the bound browser before operating on it. ## Affected versions and remediation This report applies to @agimon-ai/po-browse-tool@0.0.0-alpha.22. - Review the evidence and your use of @agimon-ai/po-browse-tool@0.0.0-alpha.22 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.
