AI Security Review
scanned 24d ago · by lpm-firewall-aiThe preinstall hook only checks the Node version, and the inspected agent-related writes are bounded to project scaffolding invoked by the init command. The static hints did not establish malicious behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
Installation runs the Node version check; project scaffolding runs when the user invokes the init command.
Impact
No malicious change, credential transfer, or unconsented agent control-surface mutation was confirmed.
Mechanism
The lifecycle check validates the Node version. The init command creates missing project guidance and session-log files, while CLI startup initializes Feynman's own agent directory.
AI rationale
The preinstall hook only checks the Node version, and the inspected agent-related writes are bounded to project scaffolding invoked by the init command. The static hints did not establish malicious behavior.

Decision evidence
public snapshotAI called this Clean at 86.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json's preinstall only runs a Node version check.
- bin/feynman.js resolves the Pi runtime as peer dependencies, then loads the package CLI.
- The project init command targets AGENTS.md and notes/session-logs under the active project directory.
- dist/cli.js initializes Feynman's own home and agent directory during CLI startup; the inspected source shows no confirmed attack behavior.
