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. Source inspection found a first-party agent extension capability in the obfuscated MCP bundle, but did not establish its activation caller or an unconsented attack. Warn because the capability can place fetched skill content where an agent may load it. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-13T10:29:10.230Z - **Finished:** 2026-10-13T10:38:38.172Z - **Download time:** 1545 ms - **Static scan time:** 2675 ms - **AI review time:** 563721 ms - **Total time:** 567942 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:** The bundled MCP code can install downloaded skill files into platform-specific agent skill directories. This is a first-party agent extension capability; the inspected source does not establish an unconsented install or other concrete attack. - **Trigger:** Invocation of the bundled skill-management operation; its caller was not resolved in the obfuscated bundle. - **Impact:** Installed skill content may be loaded by the corresponding agent. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-13T10:38:38.172Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The code fetches skill files from a configured API and writes them under a selected platform, workspace, or managed skill directory, with a path containment check. - **Rationale:** Source inspection found a first-party agent extension capability in the obfuscated MCP bundle, but did not establish its activation caller or an unconsented attack. Warn because the capability can place fetched skill content where an agent may load it. - **Files touched:** dist/mcp.cjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json exposes dist/index.cjs as the CLI entrypoint., dist/mcp.cjs contains a skill installer that writes files into platform, workspace, or managed skill directories., dist/mcp.cjs fetches skill files from a configured API using a bearer token, then passes them to the installer., The bundle is heavily obfuscated, and the caller that activates the skill installer was not resolved. - **Evidence against:** package.json lists prepublishOnly as a build command; it shows no preinstall, install, or postinstall hook., dist/mcp.cjs checks skill file paths to keep writes within the selected skill directory. ## Affected versions and remediation This report applies to @whalent/agent@0.3.504. - Review the evidence and your use of @whalent/agent@0.3.504 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.
