AI Security Review
scanned 13d ago · by lpm-firewall-aiThe automatic per-user startup registration is a first-party agent-sync lifecycle capability and merits a warning. The daemon waits for sign-in, and the inspected configuration helpers do not show foreign Claude settings being changed.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Installing the package through a package manager that runs postinstall.
Impact
The daemon can continue running at later logins; it remains signed out until the user signs in.
Mechanism
The postinstall script repairs command targets and registers the daemon with the platform's per-user startup service.
AI rationale
The automatic per-user startup registration is a first-party agent-sync lifecycle capability and merits a warning. The daemon waits for sign-in, and the inspected configuration helpers do not show foreign Claude settings being changed.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs install.cjs from its postinstall hook.
- The installer registers its daemon during installation and creates a per-user service configured to start at login.
- The daemon scans Claude skill folders, but its source says it starts signed out and waits for skill-sync login.
- The inspected Claude configuration helpers discover local executables and set the relevant Claude home; they do not show a write to Claude settings.
Evidence against
- The daemon waits for a browser sign-in before receiving its in-memory token.
- Registration is skipped in CI or when the repair-only flag is passed.
