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 obfuscated bundle exposes agent skill file installation, but the inspected source does not establish an automatic trigger or a malicious chain. Treat this as a warning for agent capability risk rather than a confirmed attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 74.0% - **Started:** 2026-10-07T07:59:32.639Z - **Finished:** 2026-10-07T08:00:00.824Z - **Download time:** 1285 ms - **Static scan time:** 1913 ms - **AI review time:** 24986 ms - **Total time:** 28185 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 obfuscated MCP bundle includes a skill installation capability that writes files to an agent skill directory. No automatic npm-install trigger or confirmed attack was identified in the inspected source. - **Trigger:** The skill installation routine is invoked. - **Impact:** The capability can add agent skills; the inspected excerpts do not establish whether consent gates its invocation. - **Review source:** ai\_review - **Reviewed:** 2026-10-07T08:00:00.824Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It creates the resolved skill directory and writes skill files after checking their paths. - **Rationale:** The obfuscated bundle exposes agent skill file installation, but the inspected source does not establish an automatic trigger or a malicious chain. Treat this as a warning for agent capability risk rather than a confirmed attack. - **Files touched:** dist/mcp.cjs ### 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 uses obfuscated bundled code, which limits tracing its behavior., The MCP bundle has a skill installation routine that creates a destination directory and writes skill files., The manifest has a prepublishOnly build hook, but no install lifecycle hook. - **Evidence against:** The skill installation routine is not shown to run during npm installation., The inspected write routine uses a safe-path check before writing skill files. ## Affected versions and remediation This report applies to @whalent/agent@0.3.496. - Review the evidence and your use of @whalent/agent@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.
