AI Security Review
scanned 4d ago · by lpm-firewall-aiThe package sends limited runtime usage telemetry to the publisher’s host by default in interactive sessions. Because the README does not disclose that telemetry, classify it as suspicious; the inspected credential flows use the package’s license key with Polar and the publisher’s own rule-feed service.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
CLI startup requests the rule feed when a license key is available; after a free scan, or when a license check fails, interactive sessions may send telemetry unless opted out.
Impact
The publisher can observe usage and paywall events from interactive sessions. The inspected telemetry payloads do not include file contents, paths, or unrelated credentials.
Mechanism
HTTPS requests send generic event fields to getreadystack.com. A license key is also sent to the publisher’s rule-feed endpoint and to Polar for validation.
AI rationale
The package sends limited runtime usage telemetry to the publisher’s host by default in interactive sessions. Because the README does not disclose that telemetry, classify it as suspicious; the inspected credential flows use the package’s license key with Polar and the publisher’s own rule-feed service.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- After a free scan, the CLI calls `pingUse`; on an interactive terminal with telemetry opt-outs unset, it posts a use event containing the package slug, source, and reason to the publisher’s host.
- The source describes paywall counts as anonymous and documents opt-outs; its event payload contains only event type, slug, source, and reason.
- The license key is used for Polar validation and the publisher’s rule-feed request; no flow sending unrelated credentials or project data was identified.
Evidence against
- Telemetry is limited to generic event fields and is gated to interactive use, with environment-variable opt-outs.
- The CLI’s stated function is scanning energy-label product feeds, and its engine performs local feed checks.
