What problem does it solve?
Langfuse integration helps you reliably add observability to LLM-powered systems, manage prompts/datasets/evals, and query trace data without losing performance or leaking sensitive information.
Core Features & Use Cases
- Gateway tracing with @observe(): Ensures every LLM/tool-touching gateway function creates trace spans and propagates Langfuse trace IDs for cockpit deep-links.
- Safe trace hygiene: Prevents PII and sensitive secrets from being recorded in trace inputs/outputs or span metadata.
- Operational CLI workflows: Uses langfuse-cli to discover resources and query or modify traces, prompts, datasets, scores, and evals, including guidance for evaluation runs.
Quick Start
Use the langfuse skill to instrument your gateway by asking the AI to provide a step-by-step plan for adding @observe() to your LLM/tool calls and propagating trace IDs into scenario_runs while ensuring no PII is included.
