Research-first CLI agent built on Pi and alphaXiv
AI Security Review
scanned 25d ago · by lpm-firewall-aiThe install hook only enforces the supported Node version, and the inspected project configuration writes are behind an explicit command and preserve an existing AGENTS.md. The scanner signals do not establish malicious behavior in the inspected source.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation invokes the preinstall version check; project file setup requires invoking the init command.
Impact
No unconsented mutation, credential exfiltration, or other concrete attack behavior was established.
Mechanism
The lifecycle script checks the Node version. The init command creates missing research session files and preserves an existing AGENTS.md.
AI rationale
The install hook only enforces the supported Node version, and the inspected project configuration writes are behind an explicit command and preserve an existing AGENTS.md. The scanner signals do not establish malicious behavior in the inspected source.
Evidence

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The preinstall hook only runs a Node version check.
- The project setup command is user-invoked and creates missing project files without overwriting an existing AGENTS.md.
- The launcher checks for its Pi peer dependencies, then loads the packaged CLI.
- The inspected CLI child process runs the Alpha CLI with inherited environment and standard I/O.
