Classic Outlook renders with the Word engine, the new Outlook with WebView2. Lint one email file against both at once, line by line, before you send.
AI Security Review
scanned 5d ago · by lpm-firewall-aiThe CLI sends undisclosed runtime telemetry to the package vendor by default in interactive sessions, which warrants a warning. The flagged licence key is the package’s own key sent to its licensing and rules services; I found no unrelated credential collection or exfiltration.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Running a free CLI command in an interactive terminal, or reaching a license prompt in an interactive CLI or MCP session.
Impact
The vendor learns that the package was used or that a licence was missing or invalid.
Mechanism
The CLI posts usage or paywall events containing the package slug, source, and reason to getreadystack.com.
AI rationale
The CLI sends undisclosed runtime telemetry to the package vendor by default in interactive sessions, which warrants a warning. The flagged licence key is the package’s own key sent to its licensing and rules services; I found no unrelated credential collection or exfiltration.

Decision evidence
public snapshotAI called this Suspicious at 92.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- A free interactive CLI run automatically sends a usage event containing the package slug, CLI source, and a fixed reason to getreadystack.com.
- License prompts also send a paywall event with the package slug, source, and reason to getreadystack.com.
Evidence against
- The telemetry is limited to product-use fields and is skipped by CI or when DO_NOT_TRACK=1 or READYSTACK_NO_TELEMETRY is set.
- The READYSTACK_LICENSE value is the package’s own licence key, sent to Polar for validation and to Readystack’s own rules feed.
