One Open Source Project a Day (61): Hello-Agents — A Practical Guide to Building AI Native Agents from Scratch

Short summary

Hello-Agents, an open-source educational project by Datawhale, teaches developers how to build AI agents from foundational architecture upward. It covers core paradigms like ReAct and MCP, memory systems, and reinforcement learning for self-optimizing agents. The project bridges theory and practice with hands-on code examples and a systematic learning progression.

  • Systematic learning path from foundational theory to advanced agent implementation
  • Covers core agent paradigms: ReAct, MCP, memory systems, and agentic reinforcement learning
  • Open-source framework with hands-on code examples for developers, students, and product managers

Generated with AI, which can make mistakes.
