@jive-sh/skill-sync@0.4.18
Keeps one skills directory identical across every machine you work on.
AI Security Review
scanned 4d ago · by lpm-firewall-aiThe postinstall hook creates and starts a persistent daemon, but the inspected source gates service activity on explicit sign-in and documents its account-usage dashboard. Because runtime usage reports are associated with account-directory labels, classify this as suspicious identifying telemetry rather than malicious behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
Installation registers and starts the daemon; service communication and usage reporting begin only after the user signs in or the daemon resumes a saved token.
Impact
The service receives usage metrics associated with local account labels. The README discloses the dashboard feature, and logout stops reporting by ending the session.
Mechanism
The daemon sends usage readings over its authenticated service connection. The readings include tool names and account labels derived from home-relative paths.
AI rationale
The postinstall hook creates and starts a persistent daemon, but the inspected source gates service activity on explicit sign-in and documents its account-usage dashboard. Because runtime usage reports are associated with account-directory labels, classify this as suspicious identifying telemetry rather than malicious behavior.

Decision evidence
public snapshotAI called this Suspicious at 79.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The package runs install.cjs from its postinstall hook.
- The installer registers and starts the package's own daemon through the operating system's user-level startup manager.
- When connected, the daemon sends account usage readings to the service.
- Each reading includes the tool and an account directory label derived from its home-relative path.
- The README discloses the usage reporting and describes the account information shown in the dashboard.
- The daemon only resumes a network session when a saved token exists; a token is saved through the sign-in flow.
Evidence against
- The daemon waits for the user to sign in before syncing or reporting usage.
- The README describes syncing selected skills and account usage as the package's intended functions.
- The inspected source sends requests to the configured skill-sync service endpoint.
