AI Security Review
scanned 14d ago · by lpm-firewall-aiThe postinstall creates login persistence without an explicit install-time consent step, so the package warrants a warning for its background agent setup. The token and user configuration gates, plus the package-aligned sync behavior, do not support a malicious verdict.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package outside CI or repair-only mode.
Impact
The daemon may persist across logins and access Claude skill folders after configuration. No malicious data transfer or unrelated agent action was established.
Mechanism
The installer creates a platform-specific per-user startup registration for the daemon; later, a configured daemon connects to the package’s sync service and processes selected Claude skills.
AI rationale
The postinstall creates login persistence without an explicit install-time consent step, so the package warrants a warning for its background agent setup. The token and user configuration gates, plus the package-aligned sync behavior, do not support a malicious verdict.

Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs install.cjs automatically after installation, and that script calls registerDaemons during its install path.
- Outside repair-only and CI installs, the installer registers a per-user daemon that can start at login through the platform service manager.
- The daemon exits when no token is configured; its default endpoint is the package’s sync service, and login is an explicit CLI action.
- The runtime detects Claude skill folders and uses the Claude CLI for conflict reconciliation; source and built configuration code show the same integration.
Evidence against
- The daemon does not sync without a configured token, and the CLI obtains that token through an explicit login flow.
- The inspected integration is for syncing Claude skills through the package’s own service; no credential theft or unrelated account action was established.
