AI Security Review
scanned 14d ago · by lpm-firewall-aiThe postinstall hook sets up a persistent, package-owned daemon without a separate setup command, creating residual agent lifecycle risk. The inspected behavior is aligned with syncing Claude skill folders, so the evidence supports a warning rather than a malicious verdict.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Installing the package outside CI or without the repair-only flag.
Impact
The daemon can continue running after installation and restart at login. The inspected excerpts do not establish credential theft, unrelated agent configuration changes, or another active attack.
Mechanism
The installer writes a per-user launch agent or service registration and starts the daemon; the package detects Claude skills folders for syncing.
AI rationale
The postinstall hook sets up a persistent, package-owned daemon without a separate setup command, creating residual agent lifecycle risk. The inspected behavior is aligned with syncing Claude skill folders, so the evidence supports a warning rather than a malicious verdict.

Decision evidence
public snapshotAI called this Suspicious at 83.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs install.cjs from postinstall.
- The installer registers a package-owned daemon automatically, except when CI is set or repair-only is passed.
- On macOS, the installer writes a login agent configured to run at login and stay active after failures.
- The package discovers Claude skills folders and locates the Claude executable for its sync and reconciliation workflow.
- The source and built config/reconcile files show the same Claude-specific folder and executable behavior.
Evidence against
- The inspected installer manages its own daemon registration and command targets; the excerpts show no changes to unrelated agent configuration.
