tscircuit@0.0.3050
**Design circuit boards with TypeScript and React.**
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe exported browser bundle performs runtime analytics by default and includes page-domain identification and exception capture, without a telemetry disclosure in the inspected README. This is a warning-level telemetry concern; no install-time attack or credential theft was identified.
Static reason
No blocking static signals were detected.
Trigger
Import or load the ./browser entry; UI activity or an error triggers event capture.
Impact
The service receives the embedding domain or anonymous identifier and runtime event or exception data without a documented disclosure in the inspected README.
Mechanism
The bundle initializes PostHog for postpig.tscircuit.com by default, identifies users by page domain or a persisted anonymous ID, and captures activity and exception details. A global opt-out is available.
AI rationale
The exported browser bundle performs runtime analytics by default and includes page-domain identification and exception capture, without a telemetry disclosure in the inspected README. This is a warning-level telemetry concern; no install-time attack or credential theft was identified.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package exports dist/browser.min.js as its ./browser entry point.
- That browser bundle initializes analytics on load and sends activity and exception data to postpig.tscircuit.com, using the page domain or a persisted anonymous ID; telemetry can be disabled with TSCIRCUIT_TELEMETRY_DISABLED.
- The README describes circuit design functionality and contains no telemetry disclosure in the inspected introduction.
Evidence against
- The manifest has no install, preinstall, or postinstall lifecycle hook.
- The Node entry point re-exports circuit and evaluation libraries.
- The CLI sets a path to the package's browser bundle and imports the CLI; it does not itself read or transmit credentials in the inspected code.
