AI Security Review
scanned 4d ago · by lpm-firewall-aiThe package appears to perform its advertised accessibility linting, but it sends runtime usage and license-gate telemetry to the vendor without documenting that behavior for users. The payload is limited and can be disabled with environment flags, so this warrants a warning rather than a publish block.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
An interactive free CLI run completes, or a paid check encounters a missing or invalid license in an interactive CLI or MCP session.
Impact
The vendor can learn that the package was used and whether a license was missing or invalid; the observed event payload does not include credentials or scanned file contents.
Mechanism
The package posts a small event with the package slug, source and event reason to getreadystack.com/api/ev. DO_NOT_TRACK=1, READYSTACK_NO_TELEMETRY or CI suppresses the events.
AI rationale
The package appears to perform its advertised accessibility linting, but it sends runtime usage and license-gate telemetry to the vendor without documenting that behavior for users. The payload is limited and can be disabled with environment flags, so this warrants a warning rather than a publish block.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- After a free interactive CLI run, the package sends a usage event to getreadystack.com containing only the package slug, CLI source and a free-use label; environment flags can disable it.
- When a license is missing or invalid, an interactive CLI or MCP session can send a paywall event containing the package slug, source and reason.
- The README describes the CLI and license but does not disclose these runtime telemetry events.
Evidence against
- The package’s stated purpose and implementation are an accessibility declaration linter.
- License keys are used for validation with api.polar.sh and for the package’s rules feed; the reviewed telemetry does not include keys, file contents or environment values.
- The telemetry has opt-out environment variables and is limited to interactive CLI or MCP sessions.
