## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 15 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:** 0.1.22
- **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 deliberate obfuscation and an active update check, but does not establish a concrete malicious chain. Classify as suspicious and warn pending clearer inspection of update and feedback behavior.

## Latest scan

## Security analysis

### Published attack-surface review

- **Summary:** The package deliberately obfuscates its published code and the launcher performs an update check before runtime startup. The inspected source does not establish harmful update behavior or a concrete attack.

- **Trigger:** Running the packaged CLI.

- **Impact:** Unresolved risk from opaque runtime behavior; no verified payload execution or credential disclosure was established.

- **Evidence paths:** package.json, dist/launcher.js, dist/feedback.js

- **Review source:** ai\_review

- **Reviewed:** 2026-10-12T11:26:52.108Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Obfuscated launcher checks for updates and starts the runtime; feedback reporting is gated by shouldAutoReport.

- **Rationale:** The source shows deliberate obfuscation and an active update check, but does not establish a concrete malicious chain. Classify as suspicious and warn pending clearer inspection of update and feedback behavior.

- **Files touched:** package.json, dist/launcher.js, dist/feedback.js

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 76.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** package.json runs an obfuscation script when publishing, and the published CLI points to dist/index.js., The obfuscated launcher performs an update check before launching its runtime., Feedback reporting is conditional on shouldAutoReport; the inspected excerpt does not establish its full scope or recipient.

- **Evidence against:** package.json has no install, preinstall, or postinstall hook; prepublishOnly is a publishing-time build hook.

## Affected versions and remediation

This report applies to @funny-booth/agent-core@0.1.22.

- Review the evidence and your use of @funny-booth/agent-core@0.1.22 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.
