AI Security Review
scanned 17h ago · by lpm-firewall-aiThe package sends runtime telemetry to its own PostHog endpoint, including preview error messages and stacks, without disclosure in its README. This is a warning-level telemetry concern; the inspected registry credential flow is user-initiated and directed to the registry service.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Importing the browser entry initializes PostHog; rendering the preview can then trigger activity and error telemetry.
Impact
Application-specific details included in preview errors or stacks may be sent to the telemetry service.
Mechanism
The bundle initializes PostHog by default and captures error messages and stacks, with an opt-out global setting.
AI rationale
The package sends runtime telemetry to its own PostHog endpoint, including preview error messages and stacks, without disclosure in its README. This is a warning-level telemetry concern; the inspected registry credential flow is user-initiated and directed to the registry service.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The bundled code initializes PostHog at import time and sends telemetry to https://postpig.tscircuit.com.
- Telemetry can be disabled with TSCIRCUIT_TELEMETRY_DISABLED, but the package does not disclose it in its README.
- When preview errors occur, the code sends their messages and stacks to PostHog.
- Activity events include the embedding domain and an anonymous ID.
Evidence against
- The registry login flow is initiated by a sign-in action and sends its token to the tscircuit registry service.
- The telemetry uses an anonymous ID or embedding domain; no evidence showed it collecting registry credentials.
