PocketFlow Tutorial: Minimal LLM Framework with Graph-Based Power

May 4, 2026 · View on GitHub

Learn how to build agentic applications with The-Pocket/PocketFlow, a minimalist graph framework that still supports workflows, multi-agent patterns, RAG, and human-in-the-loop flows.

Why This Track Matters

PocketFlow proves that useful agent frameworks can be extremely small while remaining expressive. It is ideal for developers who want clarity, control, and portability instead of heavyweight abstractions.

This track focuses on:

core graph abstractions in a minimal framework
composable patterns for agents, workflows, and RAG
multi-agent and HITL design without framework bloat
scaling lightweight patterns into real applications
