AI Security Review
scanned 4d ago · by lpm-firewall-aiThe postinstall hook installs a login daemon, a consequential behavior that the README clearly describes. The daemon waits for explicit sign-in before syncing, limits file synchronization to selected skills, and sends requests to the configured service endpoint.
Static reason
One or more suspicious static signals were detected.
Trigger
Package installation registers and starts the daemon; syncing starts after sign-in or resumes with a saved token.
Impact
Expected sync and update behavior for this package; no unrelated credential collection or attack behavior identified.
Mechanism
The daemon syncs selected skills with its configured service and checks for updates through the installing package manager.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The postinstall hook runs install.cjs, which repairs command targets and registers the package daemon.
- The README discloses that installation registers the daemon to start at login and that it checks for package updates every five minutes.
- At daemon startup, syncing resumes only if a saved token exists; otherwise it waits for the user to sign in with skill-sync login.
- Sync code filters to selected skills, and requests use the configured skill-sync service endpoint.
Evidence against
- Postinstall creates login persistence and starts the daemon, so installation has an automatic side effect.
- The daemon can install updates through the package manager without a separate update command; this behavior is documented.
