Can I track LLM costs with this skill?

Absolutely. The skill provides patterns for logging usage data, allowing you to monitor costs, token consumption, and latency across different models.

Why is flushing important in Langfuse implementation?

In serverless or short-lived environments, calling the flush method ensures that batched traces are sent to the Langfuse server before the process exits, preventing data loss.

Langfuse is an open-source platform for LLM observability, helping developers trace, monitor, and evaluate the performance of AI applications in production.

Does this skill support LangChain?

Yes, it includes specific implementation patterns for integrating LangChain applications with Langfuse for automated tracing of chains and agents.
