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:** 0.3.508 - **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. The skill-management feature is activated through an MCP tool request, and the manifest has no npm install hook. Because it can add remote skill content to machine or workspace agent directories, this warrants a warning as a first-party agent extension capability. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-10-14T14:53:54.557Z - **Finished:** 2026-10-14T14:55:51.108Z - **Download time:** 5906 ms - **Static scan time:** 1950 ms - **AI review time:** 108693 ms - **Total time:** 116551 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 package provides a first-party MCP skill installer that can place downloaded skill content in agent directories. - **Trigger:** An MCP client invokes the skill installation action. - **Impact:** Installed skill content may affect later agent behavior; the inspected source does not establish covert execution or a confirmed attack. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-14T14:55:51.108Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The tool fetches the selected skill from the configured platform and writes its files into the resolved agent skill directory. - **Rationale:** The skill-management feature is activated through an MCP tool request, and the manifest has no npm install hook. Because it can add remote skill content to machine or workspace agent directories, this warrants a warning as a first-party agent extension capability. ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The flagged MCP location resolves agent-specific directories; nearby code supports machine and workspace skill locations., An incoming MCP tool call can request a skill download and installation using a selected slug, platform URL, and bearer token., The installer writes returned skill files beneath the resolved directory and rejects paths outside that directory., The manifest's prepublishOnly hook runs the build; no install hook is declared. - **Evidence against:** The skill installation is activated through an MCP tool request, not an npm lifecycle hook., The source shows a first-party skill-management feature, with no evidence that the downloaded content is automatically executed. ## Affected versions and remediation This report applies to @whalent/agent@0.3.508. - Review the evidence and your use of @whalent/agent@0.3.508 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.
