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:** 0.3.502 - **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 package has no consumer install lifecycle hook, and the suspicious signals do not establish malicious behavior. The obfuscated bundle's agent skill installation capability has unresolved activation and consent behavior, supporting a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 72.0% - **Started:** 2026-10-12T02:39:44.632Z - **Finished:** 2026-10-12T02:40:17.159Z - **Download time:** 2058 ms - **Static scan time:** 1863 ms - **AI review time:** 28604 ms - **Total time:** 32527 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 bundle contains a capability to install skill files into supported agent directories. No concrete attack surface was established because the inspected code does not show unconsented or automatic activation. - **Trigger:** An unresolved caller to the bundle's skill installation function; the relevant activation path could not be verified from the bounded excerpts. - **Impact:** If exposed and invoked, it can add files to agent configuration directories; no evidence establishes that it executes or persists without user action. - **Evidence paths:** dist/mcp.cjs - **Review source:** ai\_review - **Reviewed:** 2026-10-12T02:40:17.159Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The function resolves a destination, creates its directory, and delegates writing skill files. - **Rationale:** The package has no consumer install lifecycle hook, and the suspicious signals do not establish malicious behavior. The obfuscated bundle's agent skill installation capability has unresolved activation and consent behavior, supporting a warning. - **Files touched:** dist/mcp.cjs ### Review decision - **Verdict:** Suspicious - **Confidence:** 72.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest declares only a prepublishOnly lifecycle hook, which runs during publishing rather than consumer installation., The MCP bundle maps skill destinations to Claude, Cursor, or generic agent directories under the user home., Its skill installer creates the resolved directory and writes skill files when invoked., The bundle is heavily obfuscated, limiting verification of how the skill installer is exposed and activated. - **Evidence against:** The inspected manifest has no preinstall, install, or postinstall hook., The inspected skill installer is a capability in the MCP bundle; no evidence here shows it runs automatically on package installation. ## Affected versions and remediation This report applies to @whalent/agent@0.3.502. - Review the evidence and your use of @whalent/agent@0.3.502 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.
