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. 17 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:** 0.3.497 - **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 inspected package metadata and flagged bundle excerpts do not establish malicious behavior, and the manifest has no install-time lifecycle hook. Obfuscation reduces confidence, but the scanner's payload-loader signal is not proof of an active attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-09T04:35:49.579Z - **Finished:** 2026-10-09T04:36:11.730Z - **Download time:** 1539 ms - **Static scan time:** 1873 ms - **AI review time:** 18738 ms - **Total time:** 22151 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 surface was identified from the inspected source excerpts. The package has a publish-time build hook and an obfuscated agent runtime entrypoint. - **Trigger:** Package publication or normal CLI/runtime use. - **Impact:** No attack effect was confirmed. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T04:36:11.730Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The manifest runs a build for prepublishOnly; no install hook is declared. The inspected bundled URL fragment is part of schema-reference code. - **Rationale:** The inspected package metadata and flagged bundle excerpts do not establish malicious behavior, and the manifest has no install-time lifecycle hook. Obfuscation reduces confidence, but the scanner's payload-loader signal is not proof of an active attack. ### Review decision - **Verdict:** Clean - **Confidence:** 76.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** The manifest declares a publish-time build hook, with no install-time lifecycle hook., The manifest identifies the package as a Whalent Agent runtime wrapper and lists agent protocol libraries as dependencies., The flagged URL fragment occurs in bundled schema-reference code; inspection did not establish a package-controlled payload loader or concrete attack behavior. - **Evidence against:** The distributed entrypoints are heavily obfuscated, which limits behavioral review. ## Affected versions and remediation This report applies to @whalent/agent@0.3.497. - Review the evidence and your use of @whalent/agent@0.3.497 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.
