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:** 0.3.523 - **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 source shows a real agent skill installation capability that writes platform-provided files into selected agent scopes. Since no concrete attack or lifecycle abuse was established, this warrants a warning rather than a publish block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-18T17:59:34.502Z - **Finished:** 2026-10-18T18:00:47.226Z - **Download time:** 1025 ms - **Static scan time:** 1457 ms - **AI review time:** 70242 ms - **Total time:** 72724 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 includes a skill installation capability that can place downloaded files in agent skill directories. This leaves a guarded agent-extension risk; the inspected source did not establish a concrete attack. - **Trigger:** A user or agent invokes the skill installation operation with a selected scope and skill. - **Impact:** Installed skill content can affect later agent behavior; no malicious content or unconsented configuration change was established. - **Evidence paths:** dist/index.cjs, dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-18T18:00:47.226Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI retrieves skill files from the configured platform and writes them under the chosen machine, workspace, or agent skill directory. - **Rationale:** The source shows a real agent skill installation capability that writes platform-provided files into selected agent scopes. Since no concrete attack or lifecycle abuse was established, this warrants a warning rather than a publish block. - **Files touched:** dist/index.cjs, dist/mcp.cjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest points the package’s CLI entrypoint to dist/index.cjs and declares no npm lifecycle hooks., The skill integration selects platform agent directories and supports machine, workspace, and agent scopes., The bundled skill helper downloads files from the configured platform and writes them into the selected skill directory., The CLI handler inspected in dist/index.cjs connects the download and installation steps to a requested skill operation. - **Evidence against:** No source evidence established an install-time trigger or an unrelated credential recipient., The inspected behavior is a skill-management feature; no malicious payload or unconsented agent configuration change was established. ## Affected versions and remediation This report applies to @whalent/agent-core@0.3.523. - Review the evidence and your use of @whalent/agent-core@0.3.523 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.
