AI Security Review
scanned 4d ago · by lpm-firewall-aiThe source sends runtime usage telemetry to the publisher’s host, but does not disclose it in the README. Its payloads contain only package and event metadata, so this warrants a warning rather than a block.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
After a free CLI scan, or when a license check fails; telemetry is limited to interactive or MCP sessions unless opted out.
Impact
The publisher can track package usage and paywall events; no sensitive user or project data was identified in the event payloads.
Mechanism
HTTPS POST events report the package slug, invocation source and a reason such as free, no_key or invalid.
AI rationale
The source sends runtime usage telemetry to the publisher’s host, but does not disclose it in the README. Its payloads contain only package and event metadata, so this warrants a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- A free CLI run sends a usage event to getreadystack.com containing the package slug, CLI source and a fixed reason.
- The usage ping runs after free scans; telemetry is disabled by opt-out environment variables, but the README does not disclose it.
- License or paywall events send only the package slug, source and reason to the same host.
Evidence against
- The reported events do not include file contents, credentials, hostnames or other identifying details.
- The package is a CLI audit tool, and its license checks and rule feed serve its paid scanning features.
- The network pings are limited to interactive or MCP use and can be disabled with DO_NOT_TRACK=1 or READYSTACK_NO_TELEMETRY.
