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 does not automatically execute during npm installation, so the evidence does not support a block. Its obfuscated command runtime can globally replace its wrapper at runtime and alter MCP configuration, warranting a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-22T18:06:11.329Z - **Finished:** 2026-09-22T18:07:56.429Z - **Download time:** 1009 ms - **Static scan time:** 1630 ms - **AI review time:** 102460 ms - **Total time:** 105100 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 install-time attack was identified. When the whalent command is run, its obfuscated runtime can globally install a selected wrapper release and can modify MCP configuration. - **Trigger:** A user runs the whalent command or invokes its MCP configuration functionality. - **Impact:** A runtime-selected package release can replace the global wrapper, and MCP configuration can be changed. No covert exfiltration or automatic install-time mutation was confirmed. - **Evidence paths:** dist/index.cjs, dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-22T18:07:56.429Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime uses a spawned npm global-install command for the wrapper package; MCP helpers update configuration objects and write them to disk. - **Rationale:** The package does not automatically execute during npm installation, so the evidence does not support a block. Its obfuscated command runtime can globally replace its wrapper at runtime and alter MCP configuration, warranting a warning. ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package exposes a whalent command-line entrypoint., The command runtime contains an updater that invokes npm with a global install of the wrapper package and a selected version., The MCP runtime can write Claude MCP server configuration entries. - **Evidence against:** package.json contains no preinstall, install, or postinstall lifecycle hook., The inspected MCP credential request uses a token supplied through command-line or environment configuration for its configured platform URL. ## Affected versions and remediation This report applies to @whalent/agent@0.3.458. - Review the evidence and your use of @whalent/agent@0.3.458 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.
