AI Security Review
scanned 4d ago · by lpm-firewall-aiThe package performs undisclosed runtime telemetry to its publisher's endpoint, which warrants a warning under the telemetry rules. The observed event carries only package and invocation metadata, while license keys go to the license service and publisher service used for the advertised paid features.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A human-seat CLI free scan, or a missing or invalid license in an eligible terminal or MCP session.
Impact
The publisher can observe usage and paywall events. The reviewed telemetry does not transmit credentials, file contents, or project data.
Mechanism
The CLI or license module posts a small event with the package slug, invocation source, and fixed reason to getreadystack.com; opt-out environment variables suppress the events.
AI rationale
The package performs undisclosed runtime telemetry to its publisher's endpoint, which warrants a warning under the telemetry rules. The observed event carries only package and invocation metadata, while license keys go to the license service and publisher service used for the advertised paid features.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The CLI sends a runtime usage event containing the tool slug, source, and a fixed reason to getreadystack.com.
- Telemetry is skipped when DO_NOT_TRACK=1, READYSTACK_NO_TELEMETRY is set, or CI is set; the README does not disclose this telemetry.
- License validation sends the supplied license key to api.polar.sh, and the rules feed sends a license key to the package publisher's getreadystack.com service.
Evidence against
- The manifest has no lifecycle scripts; the reviewed network calls are in CLI flows.
- The usage event contains no credentials, file contents, or project data.
- The package is described as a Japanese document retention rules checker, matching the behavior of its local scanning engine.
