Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 13 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Unknown - **Selected version:** 0.1.29 - **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 shipped runtime is deliberately obfuscated, leaving the feedback destination and some behavior difficult to verify. Inspected source does not establish a concrete attack, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 77.0% - **Started:** 2026-10-16T10:03:09.451Z - **Finished:** 2026-10-16T10:04:01.297Z - **Download time:** 762 ms - **Static scan time:** 314 ms - **AI review time:** 50769 ms - **Total time:** 51846 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:** No concrete attack was established, but obfuscation in the shipped runtime leaves some behavior unresolved. The launcher checks for package updates, and the feedback module reports selected failures. - **Trigger:** Running the launcher or triggering a selected failure in a running tool. - **Impact:** The update check is consistent with package maintenance. The report contents and destination cannot be fully verified from the inspected obfuscated source. - **Evidence paths:** dist/launcher.js, dist/feedback.js - **Review source:** ai\_review - **Reviewed:** 2026-10-16T10:04:01.297Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The launcher queries the npm registry; the feedback module posts a report to a destination encoded in the module. - **Rationale:** The shipped runtime is deliberately obfuscated, leaving the feedback destination and some behavior difficult to verify. Inspected source does not establish a concrete attack, so this warrants a warning rather than a block. - **Files touched:** package.json, dist/launcher.js, dist/feedback.js, dist/index.js - **Network endpoints:** https://registry.npmjs.org/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 77.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The publish script explicitly runs an obfuscation step, and the shipped launcher and feedback modules use encoded strings and indirect property lookups, which limits static verification of their behavior., The launcher checks the npm registry for a newer package version and the feedback module sends a report when selected failures occur; the report recipient is obscured in the inspected code., The MCP entrypoint requires portal credentials from its environment and uses the local vault for token reads and saves. - **Evidence against:** The manifest has no preinstall, install, or postinstall hook; its only publish hook builds the package., The inspected launcher update check targets registry.npmjs.org, and the MCP entrypoint requires explicit portal credentials to start. No concrete credential theft, destructive action, or remote code execution was established. ## Affected versions and remediation This report applies to @funny-booth/agent-core@0.1.29. - Review the evidence and your use of @funny-booth/agent-core@0.1.29 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.
