AI Security Review
scanned 4d ago · by lpm-firewall-aiThe package sends undisclosed runtime usage telemetry to its publisher after a free interactive CLI run. The event is limited to package-use fields and has opt-outs, so this warrants a warning rather than a malicious verdict.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A free CLI check completes in an interactive terminal; CI and configured opt-outs suppress the event.
Impact
The publisher learns that the tool was used, without the event containing file contents or credentials.
Mechanism
The CLI sends a POST with the tool slug, CLI source and free-use reason to getreadystack.com/api/ev.
AI rationale
The package sends undisclosed runtime usage telemetry to its publisher after a free interactive CLI run. The event is limited to package-use fields and has opt-outs, so this warrants a warning rather than a malicious verdict.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The CLI posts a usage event containing the tool slug, source and reason to getreadystack.com/api/ev.
- The event is sent after a free CLI run without a separate telemetry prompt.
- The code provides opt-out environment variables and limits this event to interactive use, but the README describes the free feature without disclosing telemetry.
Evidence against
- The event contains package-use fields rather than credentials, file contents or identifying user data.
- The README describes the package as a CSV checker with paid reporting features.
