AI Security Review
scanned 14d ago · by lpm-firewall-aiThe postinstall automatically registers a persistent per-user daemon, creating residual lifecycle setup risk despite its CI and repair-only guards. The inspected source supports a warning for package-owned extension lifecycle behavior, not a confirmed malicious attack.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package outside CI and without the repair-only flag.
Impact
The daemon can continue running at login and sync the configured skills directory using the saved token and endpoint.
Mechanism
The installer creates and starts a per-user login agent, systemd unit, or scheduled task for the package daemon.
AI rationale
The postinstall automatically registers a persistent per-user daemon, creating residual lifecycle setup risk despite its CI and repair-only guards. The inspected source supports a warning for package-owned extension lifecycle behavior, not a confirmed malicious attack.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs install.js during postinstall and declares platform-specific optional packages under aliases of this package.
- The installer repairs command targets, registers daemons, and removes its install script during postinstall.
- On macOS, the installer creates a login agent that starts at login and restarts after unsuccessful exits.
- On Linux, the installer enables and starts a per-user systemd unit immediately.
- The installer skips daemon registration only for repair-only runs or when CI is set; otherwise it registers the package daemon.
- The package detects Claude skills directories, and its CLI syncs files using a saved token and configured endpoint.
Evidence against
- The daemon registration is scoped to the current user and package-owned daemon; the installer includes CI and repair-only skip conditions.
- Inspected source shows no unrelated recipient or credential transfer; the sync caller sends its saved token to the configured endpoint.
