langfuse
Programmatic Langfuse data access and documentation lookup via CLI and web resources.
- Query and modify Langfuse data (traces, prompts, datasets, scores, sessions) using the
langfuse-clivia npx with full REST API schema discovery - Access current Langfuse documentation through three methods: structured index (llms.txt), individual markdown pages, and cross-doc search API
- Includes use-case-specific reference guides for instrumentation, prompt migration, user feedback capture, SDK upgrades, and CLI workflows
- Requires Langfuse API credentials (public and secret keys) set as environment variables; supports cloud and self-hosted instances
Langfuse
This skill helps you use Langfuse effectively across all common workflows: instrumenting applications, migrating prompts, debugging traces, and accessing data programmatically.
Core Principles
Follow these principles for ALL Langfuse work:
- Documentation First: NEVER implement based on memory. Always fetch current docs before writing code (Langfuse updates frequently) See the section below on how to access documentation.
- CLI for Data Access: Use
langfuse-cliwhen querying/modifying Langfuse data. See the section below on how to use the CLI. - Best Practices by Use Case: Check the relevant reference file below for use-case-specific guidelines before implementing
- Use latest Langfuse versions: Unless the user specified otherwise or there's a good reason, always use the latest version of Langfuse SDKs/APIs.

4langfuse-cli
Interact with Langfuse and access its documentation. Use when needing to (1) query or modify Langfuse data programmatically via the CLI — traces, prompts, datasets, scores, sessions, and any other API resource, (2) look up Langfuse documentation, concepts, integration guides, or SDK usage, or (3) understand how any Langfuse feature works. This skill covers CLI-based API access (via npx) and multiple documentation retrieval methods.
