AI Security Review
scanned 10d ago · by lpm-firewall-aiThe postinstall hook automatically registers and starts a package-owned user daemon at login on supported non-CI installs. Its source waits for explicit login before syncing, supporting a persistence warning rather than a finding of confirmed malicious behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package outside CI, when the postinstall hook runs.
Impact
The package daemon can start at login and persist across restarts without a separate setup command.
Mechanism
The installer writes an operating-system login service or task and enables or starts it.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs install.cjs during postinstall and declares platform packages as aliases to release variants of the same package.
- On ordinary installs, the installer registers its daemon; only CI or an explicit repair-only invocation skips registration.
- The installer writes per-user startup configuration and enables or starts the daemon on supported systems.
- The daemon waits for an explicit skill-sync login before syncing when no saved token exists.
Evidence against
- The daemon registration serves the package's stated background sync function and is scoped to a user account.
- The inspected source did not establish credential disclosure or changes to an unrelated agent control surface.
