AI Security Review
scanned 22d ago · by lpm-firewall-aiThe install hook only checks the Node version, and the executable loads the bundled CLI after resolving its runtime dependencies. The flagged project configuration writes are part of an explicit init command and preserve existing files; no attack behavior was established.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The preinstall hook runs during installation to check the Node version; project initialization requires the user to invoke the init command.
Impact
No malicious effect was established from these behaviors.
Mechanism
The hook checks the runtime version. The init command creates project guidance and session-log files only when they are absent.
AI rationale
The install hook only checks the Node version, and the executable loads the bundled CLI after resolving its runtime dependencies. The flagged project configuration writes are part of an explicit init command and preserve existing files; no attack behavior was established.
Decision evidence
public snapshotAI called this Clean at 97.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The preinstall hook runs a Node version check that exits only when the installed Node version is unsupported.
- The executable resolves its Pi runtime dependencies and then imports the bundled CLI.
- The CLI initializes telemetry and derives command metadata from recognized commands and limited flag values.
- The project file operation is registered as an explicit init command; it creates AGENTS.md only when that file is absent.
