AI Security Review
scanned 13d ago · by lpm-firewall-aiThe scanner’s lifecycle signal resolves to a Node version check, and source inspection did not establish malicious install-time or runtime behavior. The project-file writes are limited to missing workspace scaffolding.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation runs the preinstall Node version check; invoking the command starts the CLI.
Impact
No confirmed attack surface was established by the inspected behavior.
Mechanism
The preinstall script checks the runtime version. The project extension creates missing workspace scaffolding, while inspected dependencies provide research, authentication, prompting, and XML parsing functions.
AI rationale
The scanner’s lifecycle signal resolves to a Node version check, and source inspection did not establish malicious install-time or runtime behavior. The project-file writes are limited to missing workspace scaffolding.

Decision evidence
public snapshotAI called this Clean at 83.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json’s preinstall hook runs a Node version check; the manifest has no other install lifecycle hook.
- The launcher checks the Node version and Pi runtime, then loads the CLI when invoked.
- The project extension creates missing research workspace files and skips files that already exist.
- Inspected dependency sources expose prompt, alphaXiv research and authentication, and XML parsing APIs.
