AI Security Review
scanned 4d ago · by lpm-firewall-aiThe flagged license-key flow serves the package's stated licensing function, and the usage ping sends only limited event fields to the vendor. Because the runtime telemetry is not disclosed in the README, classify the package as suspicious under the telemetry rule.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
After a free CLI run when stdin or stdout is a TTY, unless an opt-out variable or CI is set.
Impact
Reports that the package was used; the event contains no observed host, user, project, or file data.
Mechanism
POSTs an event with the package slug, source, and fixed reason to https://getreadystack.com/api/ev.
AI rationale
The flagged license-key flow serves the package's stated licensing function, and the usage ping sends only limited event fields to the vendor. Because the runtime telemetry is not disclosed in the README, classify the package as suspicious under the telemetry rule.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Interactive free CLI runs send a usage event containing only the package slug, CLI source, and a fixed reason to getreadystack.com.
- The usage ping is triggered after a free run and is gated on a TTY; it can be disabled with DO_NOT_TRACK=1 or READYSTACK_NO_TELEMETRY.
- License validation sends the supplied Readystack key to getreadystack.com for the package's licensing flow.
- The README describes the package's free and licensed features but does not disclose the usage ping.
Evidence against
- The telemetry payload contains no hostname, username, file contents, environment values, or other identifying details.
- The ping targets the package vendor's own service and has opt-out environment variables.
- The flagged credential flow uses a supplied license key for validation, consistent with the package's paid licensing purpose.
