⚠ Under reviewCore runtime for Whalent Agent
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe inspected manifest has no lifecycle hook, and the reviewed agent skill writes occur through explicit MCP tool requests. The heavily obfuscated primary entrypoint prevents resolving the package’s full behavior, so further review is warranted without a confirmed attack finding.
Static reason
One or more suspicious static signals were detected.
Trigger
Running the package CLI.
Impact
No specific harmful effect was established; the unresolved entrypoint behavior needs further review.
Mechanism
The entrypoint’s obfuscated code could not be fully resolved through static inspection.
AI rationale
The inspected manifest has no lifecycle hook, and the reviewed agent skill writes occur through explicit MCP tool requests. The heavily obfuscated primary entrypoint prevents resolving the package’s full behavior, so further review is warranted without a confirmed attack finding.
Evidence
dist/index.cjs
Decision evidence
public snapshotAI called this Manual Review at 64.0% confidence as Unknown with high false-positive risk.
AI review observations
- The manifest names dist/index.cjs as the package entrypoint and declares no lifecycle scripts.
- The skill-management handler downloads and installs files only when its action is install; the MCP request handler routes requested tools to that logic.
- The flagged helper maps skill locations to supported agent directories, and writes are constrained to paths under the selected skill directory.
- The primary CLI bundle is exceptionally large and heavily obfuscated, so its complete runtime behavior remains unresolved.
Evidence against
- The manifest declares no install-time lifecycle hook.
- The inspected skill installation flow is reached through an MCP tool request and an explicit install action.
