AI Security Review
scanned 22d ago · by lpm-firewall-aiThe inspected preinstall hook only checks the Node version. The flagged agent configuration write is a user-invoked project setup command that preserves existing files, and the bundled CLI follows its normal launch path.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The npm preinstall hook runs during installation; project setup runs when a user invokes the init command.
Impact
No harmful effect was established from these behaviors.
Mechanism
Preinstall checks the Node version. The init command creates project-local guidance and session-log files only when they are absent.
AI rationale
The inspected preinstall hook only checks the Node version. The flagged agent configuration write is a user-invoked project setup command that preserves existing files, and the bundled CLI follows its normal launch path.

Decision evidence
public snapshotAI called this Clean at 98.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json sets preinstall to a Node version check; the check compares versions and exits for unsupported Node.
- The project setup behavior is registered as an explicit `init` command and resolves AGENTS.md under the current project directory.
- The init command creates AGENTS.md only if it is absent, and keeps an existing file.
- The bin entrypoint imports the bundled CLI; the CLI launches Pi for the selected command.
