Langfuse Agent Skills — Setup Guide

Source: langfuse/skills GitHub: langfuse/skills Skills: 6 skills · 13.1K total installs Category: LLM Observability First Seen: catalogued August 15, 2026 evening sweep Quality Tier: 🟢 Production (official org — Langfuse, the LLM observability platform)

Langfuse's official skills teach agents to instrument LLM calls with tracing, manage prompts, and run observability workflows. For a multi-model operation like CorpusIQ — DeepSeek primary, Claude fallbacks, cost tracking — tracing is how you see where tokens and money actually go.

Installation

npx skills add langfuse/skills

Prerequisites

Requirement Details
Node.js + npx For the skill installer
Langfuse account Self-hosted or cloud, with API keys
Langfuse SDK In the instrumented application

What It Provides

Skill Installs Purpose
langfuse 12.7K Core tracing and observability
langfuse-observability 217 Observability patterns
langfuse-prompt-migration 87 Migrate prompts into Langfuse management
langfuse-api 56 API reference workflows
langfuse-cli 1 CLI usage
skill-creator 4 Skill authoring helper

Quick Start

  1. Install: npx skills add langfuse/skills
  2. Start with the core langfuse skill — it carries 97% of the suite's installs
  3. Ask: "instrument my agent loop with Langfuse tracing and show cost per model"

CorpusIQ Use Cases

Use Case How
Model cost tracking Trace every LLM call to attribute spend per model and task
Agent debugging Full traces of multi-step agent runs instead of guessing where a loop degraded
Prompt management prompt-migration to move prompts out of code and into versioned management
Client observability Reference architecture for clients building LLM-powered products

Limitations / Verification

  • Publisher-page install counts verified; individual skill audit pages were not fetched for this multi-skill suite
  • The core skill dominates: observability, API, and CLI skills show sub-1K installs — treat as early content
  • Requires a running Langfuse instance and SDK integration to be useful
npx skills add langfuse/skills   # verify install works
