Tool Calling And Function Invocation For Agentic Workflows

via “agentic workflow orchestration with react loop and tool integration”

RAGFlow is a leading open-source Retrieval-Augmented Generation (RAG) engine that fuses cutting-edge RAG with Agent capabilities to create a superior context layer for LLMs

Unique: Implements a canvas-based DSL for defining agentic workflows with native ReAct loop support and multi-provider function calling (OpenAI, Anthropic, Ollama). The system includes built-in tools (retrieval, code execution, calculation) and supports streaming execution with state management for long-running workflows.

vs others: Provides more structured workflow control than simple chain-of-thought prompting by using a canvas DSL and explicit tool registry, enabling reproducible, debuggable agentic workflows with better error handling and state tracking.
