LLM observability with Langfuse — OpenTelemetry-based tracing, evaluations, prompt management, datasets, and production best practices.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Langfuse Observability Patterns > **Quick Guide:** Use the Langfuse TypeScript SDK (built on OpenTelemetry) to add observability to LLM applications. Install `@langfuse/tracing`, `@langfuse/otel`, and `@opentelemetry/sdk-node` for core tracing. Use `startActiveObservation()` for automatic context propagation or `observe()` to wrap functions. Use `@langfuse/openai` with `observeOpenAI()` for zero-config OpenAI tracing. Use `LangfuseClient` from `@langfuse/client` for prompt management, scores, and datasets. Always call `forceFlush()` or `sdk.shutdown()` in short-lived processes. --- <critical_requirements> ## CRITICAL: Before Using This Skill **(You MUST import and register `instrumentation.ts` at the top of your entry point BEFORE any other imports -- OpenTelemetry must instrument modules before they are loaded)** **(You MUST call `forceFlush()` or `sdk.shutdown()` in short-lived processes (serverless, scripts, CLI tools) -- events are batched and will be lost without explicit flushing)** …

How to install
mdr add agents-inc/skills/ai-observability-langfuse@sha256:ecf863874acf81e1The line at the top of this page pins the label git:20261016.afd0e14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
