AI Security Review
scanned 5d ago · by lpm-firewall-aiThe CLI sends usage and paywall telemetry to the publisher by default during interactive use, without documenting that collection in the README. The payload is limited to package and event details, so this warrants a warning rather than a publish block.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
A user runs the CLI interactively for a free check; paywall events can also be sent when a key is missing or invalid.
Impact
The publisher can learn that an interactive user ran the tool or encountered its paywall; the event contains no host, user, project or file data.
Mechanism
The CLI posts a small event containing the package slug, source and reason to getreadystack.com. Environment-variable opt-outs are supported.
AI rationale
The CLI sends usage and paywall telemetry to the publisher by default during interactive use, without documenting that collection in the README. The payload is limited to package and event details, so this warrants a warning rather than a publish block.

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 automatically send a usage event to getreadystack.com with the package slug, CLI source and a "free" reason.
- The event is limited to usage or paywall status; it does not include host, user, project, file or credential values.
- The telemetry is enabled by default in interactive sessions and has environment-variable opt-outs, but the README does not disclose it.
Evidence against
- Usage and paywall telemetry are limited to interactive CLI or MCP sessions and can be disabled with DO_NOT_TRACK=1 or READYSTACK_NO_TELEMETRY.
- The license key is sent to getreadystack.com for the package's rules feed, a package feature, and is not sent with the usage event.
