Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package has no install hook, and inspected command execution is consistent with its stated agent-runtime purpose. Extensive obfuscation across its runtime bundles prevents a clean assessment, but the inspected source does not establish a concrete attack, so warn rather than block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 76.0% - **Started:** 2026-10-16T08:28:24.322Z - **Finished:** 2026-10-16T08:29:30.130Z - **Download time:** 1545 ms - **Static scan time:** 1570 ms - **AI review time:** 62692 ms - **Total time:** 65808 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 established. Heavy obfuscation in the distributed runtime leaves behavior unresolved. - **Trigger:** Running the packaged CLI or MCP executable. - **Impact:** No specific harmful effect is confirmed; unresolved runtime behavior warrants a warning. - **Evidence paths:** dist/index.cjs, dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-16T08:29:30.130Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bundles obscure control flow; command execution is present in the main CLI, but its full behavior could not be resolved from inspected source. - **Rationale:** The package has no install hook, and inspected command execution is consistent with its stated agent-runtime purpose. Extensive obfuscation across its runtime bundles prevents a clean assessment, but the inspected source does not establish a concrete attack, so warn rather than block. - **Files touched:** dist/index.cjs, dist/mcp.cjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 76.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The manifest exposes a CLI entrypoint and contains no install lifecycle scripts., The MCP executable uses a string-table rotation pattern that obscures its behavior; the bundled source is difficult to assess statically., The main CLI bundle is also heavily obfuscated and includes command execution, leaving its full behavior unresolved. - **Evidence against:** The package describes itself as an agent runtime and declares SSH and terminal dependencies consistent with command-capable agent functionality., The inspected dynamic function construction in the MCP bundle occurs in bundled schema compilation code; it does not establish a payload attack. ## Affected versions and remediation This report applies to @whalent/agent-core@0.3.513. - Review the evidence and your use of @whalent/agent-core@0.3.513 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.
