MIT Updates Free The Missing Semester Course with AI Agents
The 2026 edition adds AI agents, Claude Code, Codex, MCP, and Skills to the curriculum, alongside Shell, Git, debugging, and profiling.
MIT has updated its free The Missing Semester course to the 2026 edition. It now teaches developers to work not only with core developer tools, but also with AI agents.
The course focuses on practical skills that are often given little attention in programming education.
It starts with Shell, Git, debugging, and profiling. It then moves on to software release, code quality, and modern AI-assisted development tools: Claude Code, Codex, MCP, and Skills.
The best part: the entire course is available for free. The site includes lecture notes, hands-on exercises, and YouTube recordings.
Why it matters
AnalysisThe course closes the gap between academic programming and real engineering practice by adding skills for working with AI tools that are becoming part of the standard developer workflow.
