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 shows no automatic install hook, but obfuscation prevents resolving the skill installer’s callers and activation. Manual review is needed to determine whether agent skill changes require user action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Manual Review - **Recorded analysis confidence:** 68.0% - **Started:** 2026-10-18T13:06:38.564Z - **Finished:** 2026-10-18T13:07:48.223Z - **Download time:** 1542 ms - **Static scan time:** 1937 ms - **AI review time:** 66178 ms - **Total time:** 69659 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, but the obfuscated runtime contains an unresolved skill installer that can write files in agent skill directories. - **Trigger:** The installer’s activation and caller could not be determined from the reviewed obfuscated bundle. - **Impact:** Agent skill configuration may be changed; whether this is user-invoked or automatic remains unresolved. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-18T13:07:48.223Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bundle resolves platform, project, or managed skill directories and writes supplied skill files there. - **Rationale:** The manifest shows no automatic install hook, but obfuscation prevents resolving the skill installer’s callers and activation. Manual review is needed to determine whether agent skill changes require user action. ### Review decision - **Verdict:** Manual Review - **Confidence:** 68.0% - **Recommended action:** manual\_review - **Intent class:** Unknown - **False-positive risk:** Medium - **AI review observations:** The package CLI entrypoint begins with heavily obfuscated decoder code., The MCP bundle resolves skill directories for agent platforms and writes supplied skill files there; the reviewed excerpts do not establish when that installer is called. - **Evidence against:** The manifest lists prepublishOnly running build.mjs, with no preinstall, install, or postinstall hook. ## Affected versions and remediation This report applies to @whalent/agent@0.3.518. - Review the evidence and your use of @whalent/agent@0.3.518 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.
