Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.3.496 - **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 inspected bundle exposes agent configuration and skill-writing capabilities, but the evidence does not establish their callers or consent gates. This leaves an unresolved agent capability risk, without evidence of an active attack or install-time trigger. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-10-07T08:12:31.166Z - **Finished:** 2026-10-07T08:13:20.967Z - **Download time:** 1527 ms - **Static scan time:** 1529 ms - **AI review time:** 46745 ms - **Total time:** 49801 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 bundle includes routines that modify Claude MCP configuration and install agent skills. Their activating caller and consent flow were not established by the inspected excerpts, so no concrete attack was confirmed. - **Trigger:** Unknown from the inspected excerpts; the manifest has no npm install lifecycle hook. - **Impact:** If invoked, these routines can alter agent configuration or add agent skills; the extent and consent conditions remain unresolved. - **Review source:** ai\_review - **Reviewed:** 2026-10-07T08:13:20.967Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A routine writes an MCP server entry to Claude configuration, and another creates a skill directory and writes skill files. - **Rationale:** The inspected bundle exposes agent configuration and skill-writing capabilities, but the evidence does not establish their callers or consent gates. This leaves an unresolved agent capability risk, without evidence of an active attack or install-time trigger. - **Files touched:** .claude.json ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest exposes a bundled command-line entrypoint and lists dist/mcp.cjs as package content., The bundle reads and writes Claude configuration and can add an MCP server entry., The bundle also contains a skill installation routine that writes files; the available excerpts do not establish its caller or consent gate. - **Evidence against:** The manifest defines no preinstall, install, or postinstall hook., The inspected excerpts do not establish credential collection, exfiltration, or an active attack. ## Affected versions and remediation This report applies to @whalent/agent-core@0.3.496. - Review the evidence and your use of @whalent/agent-core@0.3.496 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.
