 ## Features
 
 - **Invocation Isolation**: Safely store and retrieve data within a single Lambda invocation.
-- **Protected Lambda Context**: Built-in protection for Lambda execution metadata (requestId, [traceId](https://docs.aws.amazon.com/xray/latest/devguide/xray-concepts.html#xray-concepts-traces))
+- **Protected Lambda Context**: Built-in protection for Lambda execution metadata (requestId, [traceId](https://docs.aws.amazon.com/xray/latest/devguide/xray-concepts.html#xray-concepts-traces), [W3C Trace Context](https://www.w3.org/TR/trace-context/), [W3C Baggage](https://www.w3.org/TR/baggage/))
 - **Custom Data Storage**: Store any custom data within the invocation context
 - **Async/Await Support**: Full support for asynchronous operations with context preservation
 - **Type Safety**: Complete TypeScript type definitions
