[Hands-on] Build OpenClaw’s Core In a Single Visual Workflow

A walkthrough of rebuilding OpenClaw's agentic pipeline using Sim, an open-source visual workflow builder with 27k GitHub stars. The demo recreates OpenClaw's seven-stage agentic loop with 25 blocks and 29 connections, making routing decisions, tool calls, and memory reads visible and editable on a canvas. The post also covers FalkorDB's GraphRAG SDK, a graph-first RAG alternative that ranked #1 on GraphRAG-Bench at ICLR'26, using knowledge graphs and Cypher queries instead of vector embeddings for structurally connected retrieval.
