AI Security Review
scanned 20d ago · by lpm-firewall-aiSource inspection found a version-check-only install hook and an explicitly invoked project initializer that preserves existing files. The scanner’s dynamic loading and network signals do not establish malicious behavior in the inspected source.
Static reason
One or more suspicious static signals were detected.
Trigger
The npm preinstall hook checks the Node version; project scaffolding runs only when a user invokes `/init`.
Impact
No attack impact was identified.
Mechanism
The initializer creates missing project scaffold files and leaves existing files in place. The reviewed entrypoint loads the bundled runtime after checking for Pi peer dependencies.
AI rationale
Source inspection found a version-check-only install hook and an explicitly invoked project initializer that preserves existing files. The scanner’s dynamic loading and network signals do not establish malicious behavior in the inspected source.
Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The npm preinstall hook runs a Node version check.
- The project initializer targets the current project directory and is registered as an explicit `/init` command.
- The initializer creates scaffold files only when they do not already exist.
- The CLI entrypoint checks for its Pi peer dependencies before loading the bundled runtime.
- The inspected CLI code parses a user-supplied working directory; no attack behavior was established in the reviewed paths.
