## Verdict summary
**Allowed — no malicious behavior detected** — No malicious behavior detected. 15 low-signal pattern(s) reviewed.

- **Verdict:** Clean
- **Product-default install policy:** Allow
- **Firewall policy:** No policy match
- **Public report status:** Published
- **Threat category:** None published
- **Selected version:** 0.3.458
- **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy.

The published manifest has no install lifecycle and no self-dependency, and the readable behavior matches a user-launched agent core that talks to its own providers and a local Jupyter sidecar. Obfuscation and process, SSH, and API-key handling are package-aligned capabilities without a concrete exfiltration or control-hijack chain.

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 install-time or import-time attack was identified. The package is an obfuscated Whalent agent runtime whose process, SSH, and provider-credential use is tied to the declared CLI and local helpers.

- **Trigger:** A user or the @whalent/agent wrapper launches the whalent-core bin or MCP entry; package install does not run a lifecycle script.

- **Impact:** No concrete credential theft, remote payload execution, persistence, or unconsented agent control-surface write was established from the inspected files.

- **Review source:** ai\_review

- **Reviewed:** 2026-09-22T18:32:26.687Z

### AI review details

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

- **Mechanism:** The published manifest only depends on ssh2 and optional node-pty. Provider env keys and the Jupyter sidecar stay inside the agent runtime rather than an install hook or a hidden recipient.

- **Rationale:** The published manifest has no install lifecycle and no self-dependency, and the readable behavior matches a user-launched agent core that talks to its own providers and a local Jupyter sidecar. Obfuscation and process, SSH, and API-key handling are package-aligned capabilities without a concrete exfiltration or control-hijack chain.

### Review decision

- **Verdict:** Clean

- **Confidence:** 72.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Medium

- **Evidence for AI clean decision:** Published package.json is @whalent/agent-core 0.3.458 with main and bin dist/index.cjs and no preinstall, install, or postinstall scripts., Registry dependencies are only ssh2 and optional node-pty; the published manifest does not depend on its own package name., dist/mcp.cjs is a Node entry that freezes provider auth environment key names such as ANTHROPIC\_API\_KEY for the agent client., dist/jupyter\_sidecar.py is a local stdin/stdout NDJSON Jupyter kernel helper owned by this agent runtime.

- **Evidence against:** dist/index.cjs and dist/mcp.cjs are javascript-obfuscator style bundles, so large parts of the runtime are not plain source., Readable names include child\_process, writeDesktopLink under a Whalent path, ssh2, and provider API key handling consistent with a user-launched agent.
