Langfuse Skills

Agent Skills that teach AI coding assistants (Claude Code, Cursor, etc.) how to work with Langfuse — the open-source LLM engineering platform for tracing, prompt management, and evaluation.

Skills

Skill Description
langfuse Main skill to work with Langfuse. Query and manage traces, prompts, datasets, and scores via the Langfuse API; look up documentation; do things with best practices in mind.
migrate-to-langfuse Migrate from another LLM observability/evals platform (LangSmith, Arize, Braintrust, etc.) to Langfuse. Interviews you about scope, then handles the live tracing cutover and transfer of historical traces, datasets, prompts, and evaluators.

Installation

Cursor Plugin

Install as a Cursor plugin:

/add-plugin langfuse

skills CLI

Install via the skills CLI:

npx skills add langfuse/skills --skill "langfuse"

Manual symlink

Clone this repo and symlink the skill into your agent's skills directory:

git clone https://github.com/langfuse/skills.git /path/to/langfuse-skills
ln -s /path/to/langfuse-skills/skills/langfuse /path/to/skills-directory/langfuse

Prerequisites

You need a Langfuse account (cloud or self-hosted) and API keys:

export LANGFUSE_PUBLIC_KEY=pk-lf-...
export LANGFUSE_SECRET_KEY=sk-lf-...
export LANGFUSE_BASE_URL=https://cloud.langfuse.com  # or https://us.cloud.langfuse.com, or self-hosted URL

API keys are found in your Langfuse project under Settings > API Keys.

Usage

Once installed, the agent will automatically use these skills when relevant — for example:

  • Setting up Langfuse tracing in a project
  • Setting up CI/CD experiment gates with langfuse/experiment-action
  • Auditing existing instrumentation
  • Preparing an application and Langfuse project for the v4 platform migration
  • Migrating prompts to Langfuse prompt management
  • Querying traces, prompts, or datasets via the API
  • Looking up Langfuse docs, SDK usage, or integration guides
