The langfuse skill enables interaction with the Langfuse platform, including programmatic data access via the Langfuse CLI and retrieval of documentation for integration, debugging, and feature implementation.
Is langfuse safe to install?
Review the source first: our audit of langfuse's source files found 13 shell commands, 4 external URLs, file reads and writes (high risk). Every command and URL listed appears verbatim in the skill's source. The skill executes shell commands via npx/bunx and performs network requests to Langfuse endpoints. It also reads local reference files.

What does the skill file contain?
# 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: 1. **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. 2. **CLI for Data Access**: Use `langfuse-cli` when querying/modifying Langfuse data. See the section below on how to use the CLI. 3. **Best Practices...
