Context Engineering Intro is a practical, open-source repository created by Cole Medin that teaches developers how to apply context engineering principles to AI-assisted coding workflows. Rather than treating AI coding assistants as simple autocomplete tools, the project introduces structured methodologies for feeding project context, architectural decisions, and coding standards into AI systems like Claude Code, Codex, and OpenCode. The repository includes pre-built .claude command files for generating and executing PRPs (Prompt-Ready Plans), a template system for breaking complex features into AI-digestible tasks, and configuration examples that demonstrate how to set up project-wide rules that persist across coding sessions.
The centerpiece of the project is the WISC framework, derived from Anthropic's four context engineering strategies, which provides a repeatable process for managing context in coding sessions. Developers learn to structure their projects with CLAUDE.md files containing architecture rules, establish command workflows that guide AI assistants through multi-step implementations, and use plan-then-execute patterns that significantly reduce hallucination and architectural drift. The repository also includes practical use cases such as building with agent teams and applying context engineering to full-stack development projects.
With over 13,000 GitHub stars since its launch in 2025, Context Engineering Intro has become one of the most popular resources for developers seeking to move beyond basic AI prompting. Cole Medin, known for his YouTube content on AI coding, designed the project as both an educational resource and a working toolkit. The patterns are framework-agnostic despite centering on Claude Code, making them applicable to Cursor, Windsurf, and other AI coding environments.
