Build a Coding Agent from Scratch (thefocus.ai)

A new tutorial, “Build a Coding Agent from Scratch,” offers a comprehensive guide on creating an AI coding assistant without the need for traditional coding skills. Set to take place from December 12 to December 17, 2025, this hands-on project demystifies how software agents operate by allowing participants to build an agent that can program itself using merely English prompts. Utilizing models like Gemini 3 or Opus 4.5, the tutorial emphasizes understanding core principles over code literacy, providing a 50-line bootstrap script as a foundational start. This initiative is significant for the AI/ML community as it aims to empower a wider audience by simplifying access to coding tools and concepts that were previously reserved for skilled programmers. By breaking down the components of a coding agent into three key layers—model, tools, and prompts—the tutorial illustrates how AI can enhance problem-solving capabilities. Furthermore, it addresses the evolving relationship between humans and AI in technical fields, giving users insight into effectively leveraging these advancements. Participants will not only gain a functional AI assistant but also a deeper understanding of the underlying mechanics, fostering a new wave of innovation in software development.
