Core runtime for Whalent Agent
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package has no automatic lifecycle hook, so there is no confirmed install-time attack. Its unusually opaque, daemon-capable agent runtime accepts credentials and cannot be sufficiently traced by static inspection, warranting a non-blocking warning.
Static reason
One or more suspicious static signals were detected.
Trigger
A user or wrapper runs the package CLI or MCP executable.
Impact
The opaque executable could access the supplied agent token and workspace during normal use, but static inspection did not confirm an unauthorized recipient or attack action.
Mechanism
Obfuscated runtime code starts daemon-related functionality; the MCP entry obtains a token and platform URL from arguments or environment configuration.
AI rationale
The package has no automatic lifecycle hook, so there is no confirmed install-time attack. Its unusually opaque, daemon-capable agent runtime accepts credentials and cannot be sufficiently traced by static inspection, warranting a non-blocking warning.

Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The package exposes dist/index.cjs as both its main entry point and CLI executable.
- The MCP executable accepts a platform URL and token configuration when directly run.
- The main executable is heavily obfuscated and contains daemon PID and replacement-intent logic, preventing reliable static tracing of its privileged behavior.
Evidence against
- package.json declares no npm lifecycle scripts.
- No direct credential transmission, destructive action, or foreign AI-agent configuration mutation was confirmed from the inspected source.
