This repository is the source code for the Hugging Face Agents Course, a structured educational curriculum teaching the fundamentals and practical implementation of AI agents. The course is organized into units covering agent theory (ReAct, tool calling, observations), framework-specific tutorials (smolagents, LlamaIndex, LangGraph), agentic RAG, observability and evaluation, and a final project based on the GAIA benchmark. The content is delivered as MDX files with embedded code examples, quizzes, and links to interactive notebooks, and is translated into multiple languages (English, Spanish, French, Chinese, Korean, Russian, Vietnamese). While primarily an educational resource, the repository also contains reusable scripts for automated translation of course content and for pushing quiz data to the Hugging Face Hub, as well as CI/CD workflows for building documentation. The codebase is not a production application or a data pipeline, but rather a hybrid of educational content and supporting tooling for course maintenance.
