tracing

When a chain of LLM calls and tools produces a wrong final answer, 'the model was bad' is not a diagnosis. You need to see every step. Here is the tracing layer that turns a black box into something debuggable.

You cannot improve an LLM app you cannot see into, and LLM observability is not service monitoring. The signal is tracing multi-step chains, capturing inputs/outputs/tokens/cost, and online quality signals, not just latency and errors.
