langfuse
Langfuse is where an AI app's every call gets recorded so you can see what it did and judge whether it did it well; this is the working knowledge for setting that up and getting at the data afterwards.
LABSCO SUMMARY
Langfuse's own skills repository ships exactly one skill for its product, the langfuse skill, plus a second skill, skill-creator, that has nothing to do with Langfuse at all.
The langfuse skill covers the whole product: querying and modifying traces, managing prompts, creating datasets, running experiments, and evaluating AI applications through the Langfuse API and documentation, and the README says to invoke it for AI-observability tasks generally, even before Langfuse is configured. It needs your own account to do any of that — LANGFUSE_PUBLIC_KEY, LANGFUSE_SECRET_KEY, and a LANGFUSE_BASE_URL, from Langfuse Cloud or a self-hosted deployment.
skill-creator, the other live skill, is the generic "guide for creating effective skills" pattern that ships under the same name in unrelated repositories — it's here so an agent can write a new local skill of its own, not to do anything with Langfuse's product. That leaves this as a one-skill package for anyone who already runs Langfuse: setting up tracing in a project, migrating prompts into Langfuse's prompt management, or wiring CI/CD experiment gates, per the README's own usage list.
Our capture also holds 4 more langfuse-prefixed skills — langfuse-api, langfuse-cli, langfuse-observability, langfuse-prompt-migration — that are not live today; the README doesn't say what happened to them, so we can't tell you whether they were folded into the single langfuse skill or dropped.

WHAT'S INSIDE
Langfuse is where an AI app's every call gets recorded so you can see what it did and judge whether it did it well; this is the working knowledge for setting that up and getting at the data afterwards.
Moving an AI app's monitoring from another service — LangSmith, Arize, Braintrust and the like — over to Langfuse, with the old service kept running alongside until you have checked that the new one is recording everything correctly.
A skill is the instruction file that teaches an AI assistant to do one job your way; this is the method for writing one that actually holds up in use.
Skills for working with Langfuse, the open-source LLM engineering platform for tracing, prompt management, and evaluation.
INSTALL
SINGLE SKILL
Run this outside your AI tool, using Node.js 22.20.0 or newer. Skills CLI 1.7.2 skips skill selection; prompts cancel installation without an interactive terminal. If choosing Project when asked about installation scope, open your project's folder before running this.
Install checklist
Additional agents. ↑/↓ moves, Space toggles selections, Enter confirms.Installing to: for your intended tool. Stop if it names a different tool.Symlink (Recommended) for shared files or Copy to all agents for separate copies; review the summary before confirming installation.Install the find-skills skill? defaults to Yes, adding another skill for all projects. Choose No if you don't want that extra installation.Find the skill name in the Skills tab and put it in the command before running it. Each entry there installs independently.
