Research-first CLI agent built on Pi and alphaXiv
AI Security Review
scanned 26d ago · by lpm-firewall-aiSource inspection found a Node.js version check in preinstall and an explicitly invoked project initialization command with an existing-file guard. These behaviors do not establish a concrete attack surface; the scanner's static signals do not change that conclusion.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation triggers the preinstall version check; the project setup behavior requires invoking the init command.
Impact
No confirmed attack surface was established in the inspected behavior.
Mechanism
The launcher enforces a minimum Node.js version. The init command creates notes/session-log files and creates AGENTS.md only when it is absent.
AI rationale
Source inspection found a Node.js version check in preinstall and an explicitly invoked project initialization command with an existing-file guard. These behaviors do not establish a concrete attack surface; the scanner's static signals do not change that conclusion.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json's preinstall only checks the Node.js version.
- The init command writes research-project files when explicitly invoked, and preserves an existing AGENTS.md.
- The launcher checks the Node.js version before importing the CLI.
- The CLI delegates alpha commands to the bundled alpha executable.
