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 manifest has no automatic install hook, and the inspected source does not establish a concrete attack. Obfuscated runtime code and a very large core bundle leave material behavior unresolved, so manual review is appropriate. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-14T13:47:24.496Z - **Finished:** 2026-10-14T13:48:53.086Z - **Download time:** 3041 ms - **Static scan time:** 1963 ms - **AI review time:** 83584 ms - **Total time:** 88590 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 behavior was established. Heavy obfuscation in the CLI and bundled code leaves important runtime effects unresolved. - **Trigger:** Running the CLI entrypoint. - **Impact:** Unknown; source inspection did not establish an attack or its effects. - **Review source:** ai\_review - **Reviewed:** 2026-10-14T13:48:53.086Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The wrapper launches a separate core script and performs a runtime package-version check; obfuscated code prevents resolving the full behavior. - **Rationale:** The manifest has no automatic install hook, and the inspected source does not establish a concrete attack. Obfuscated runtime code and a very large core bundle leave material behavior unresolved, so manual review is appropriate. ### Review decision - **Verdict:** Manual Review - **Confidence:** 88.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The CLI entrypoint uses a rotated string table and heavily obfuscated identifiers., The wrapper checks for a newer package version during runtime, but the obfuscated implementation leaves the update effects unresolved., The CLI launches a separate core script, whose behavior could not be fully resolved from the available source excerpts., The MCP bundle also contains obfuscated dynamic function generation; its full behavior remains unresolved. - **Evidence against:** The manifest declares only a prepublishOnly build script, with no preinstall, install, or postinstall hook. ## Affected versions and remediation This report applies to @whalent/agent@0.3.507. - Review the evidence and your use of @whalent/agent@0.3.507 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.
