langfuse

This skill helps you use Langfuse effectively across all common workflows: instrumenting applications, migrating prompts, debugging traces, and accessing data programmatically. Follow these principles for ALL Langfuse work: Use the langfuse-cli to interact with the full Langfuse REST API from the command line. Run via npx (no install required): Start by discovering the schema and available arguments: Set environment variables before making calls: If not set, ask the user for their API keys (found in Langfuse UI → Settings → API Keys). For common workflows, tips, and full usage patterns, see references/cli.md . Three methods to access Langfuse docs, in order of preference. Always prefer your application's native web fetch and search tools (e.g., WebFetch , WebSearch , mcp_fetch , etc.) over curl when available. The URLs and patterns below work with any fetching method — the curl examples are just illustrative. Fetch the full index of all documentation pages: Returns a structured list of every doc page with titles and URLs.
