AI Fundamentals

AI Fundamentals helps you build a practical, stable way of working with AI agents. Move beyond autocomplete and occasional ChatGPT questions. Learn to give agents the right context, delegate tasks, review plans and code safely, and improve your workflow over time. The course is tool-agnostic: whether you use Cursor, Claude Code, Codex, ChatGPT, an IDE, or the command line, the principles transfer. You will cover the agentic coding mindset, task context and its limits, tokens, prompting, planning, Git checkpoints, validation, AGENTS.md, agent skills, hooks, MCPs, privacy, security, parallel agents, and cross-project workflows. Text lessons, quizzes, and video explanations guide you, and a browser-based sample project gives you a safe place to practise. You finish with a certificate. Built from my experience with SwiftLee, RocketSim, automation, and product work, this course helps you use AI productively without losing focus, control, or engineering judgment.
