Keeps one skills directory identical across every machine you work on.
AI Security Review
scanned 4d ago · by lpm-firewall-aiThe install hook sets up the package's own daemon, which the README describes. Network syncing requires an explicitly obtained machine token and applies only to selected skills; no malicious behavior was identified.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The postinstall hook registers the daemon to start at login. Syncing starts after the user signs in, or resumes when a saved token is present.
Impact
No unauthorized collection or account action was identified; the disclosed service synchronizes user-selected skills.
Mechanism
The daemon communicates with the skill-sync service and synchronizes only skills selected on the dashboard. The README discloses the daemon's automatic update behavior.
AI rationale
The install hook sets up the package's own daemon, which the README describes. Network syncing requires an explicitly obtained machine token and applies only to selected skills; no malicious behavior was identified.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The README says sign-in uses a passkey and the service issues a per-machine token to the daemon.
- The README discloses that installation registers the package's own daemon to start at login and that it automatically updates.
- The daemon resumes syncing only when a saved token exists; otherwise it stays signed out.
- Sync operations are limited to skills on the synced list; other skills are never pushed, overwritten, or deleted.
Evidence against
- The postinstall hook registers and starts a persistent daemon, and the daemon automatically upgrades itself; both behaviors are disclosed and serve the package's stated purpose.
