AI Security Review
scanned 24d ago · by lpm-firewall-aiSource inspection shows a version-check-only preinstall hook and a user-invoked init command that preserves an existing AGENTS.md. The inspected CLI code does not establish the scanner’s suspected attack behavior, so the package is clean.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Package installation runs the preinstall Node version check; project file setup occurs only when a user invokes the init command.
Impact
No confirmed attack surface was established in these paths.
Mechanism
The lifecycle script checks the installed Node version. The init command creates research-session folders and adds AGENTS.md only if it does not already exist.
AI rationale
Source inspection shows a version-check-only preinstall hook and a user-invoked init command that preserves an existing AGENTS.md. The inspected CLI code does not establish the scanner’s suspected attack behavior, so the package is clean.
Evidence
AGENTS.mdnotes/notes/session-logs/
Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The preinstall hook only runs a Node.js version check and exits when the version is unsupported.
- The init command is explicitly registered as a user-invoked Pi command; it creates project notes and writes AGENTS.md only when that file is absent.
- The package CLI resolves its bundled alpha CLI and starts it as a child process for that feature.
