Langfuse SDK Instrumentation — What Is Captured Automatically and What You Add by Hand
Creating traces is not about installing an SDK, it is about drawing boundaries. Working from the Langfuse Python SDK v4, this post lays out what the decorator, the context manager, and manual observation creation each do
