Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.3.466 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. No malicious install-time behavior or data theft was confirmed. The agent-skill installation capability remains a meaningful, incompletely attributable control-surface risk. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 74.0% - **Started:** 2026-09-27T18:55:52.751Z - **Finished:** 2026-09-27T18:56:56.711Z - **Download time:** 1013 ms - **Static scan time:** 1619 ms - **AI review time:** 61327 ms - **Total time:** 63960 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 MCP component can install skill files into agent platform directories. No confirmed automatic attack surface was found, but the bundled code does not make the effective caller consent path clear. - **Trigger:** A caller invokes the MCP skill-install capability. - **Impact:** A caller could extend an AI agent's available skills; static inspection did not establish unconsented execution or a malicious payload. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-27T18:56:56.711Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The capability chooses a machine, workspace, or managed skill directory, creates it, and writes supplied files. - **Rationale:** No malicious install-time behavior or data theft was confirmed. The agent-skill installation capability remains a meaningful, incompletely attributable control-surface risk. ### Review decision - **Verdict:** Suspicious - **Confidence:** 74.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package metadata exposes a command-line entry point and contains no install lifecycle hook in the inspected scripts., The MCP bundle resolves skill directories under a selected agent platform's home or workspace location., Its skill-install routine creates the resolved directory and writes supplied skill files., The reviewed bundle is heavily obfuscated, limiting confidence in the caller and consent path for these writes. - **Evidence against:** No package install, preinstall, or postinstall hook was found in package.json., No concrete credential export, destructive action, or unconsented install-time agent-control mutation was established in the inspected code. ## Affected versions and remediation This report applies to @whalent/agent@0.3.466. - Review the evidence and your use of @whalent/agent@0.3.466 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.
