Langfuse

The Langfuse skill teaches AI coding assistants like Claude Code and Cursor how to work with Langfuse, the open-source LLM engineering platform. It provides programmatic access to query and manage traces, prompts, datasets, and scores through the Langfuse API, and includes documentation lookup capabilities. The skill automates common workflows including setting up tracing, migrating prompts to Langfuse prompt management, auditing existing instrumentation, and querying data via API. Developers can use it to implement LLM application tracing, manage prompt experiments, and integrate Langfuse into CI/CD pipelines with experiment gates. Installation requires a Langfuse account and API keys, available through Cursor plugins, the skills CLI, or manual setup.
