Free Claude Code Course
Lydia Hallie
A video course on setting up Claude Code for a real codebase, taught by a member of the Claude Code team at Anthropic. It starts with how the model and the harness fit together and then goes through CLAUDE.md files, permission modes, skills and hooks. Later lessons get to sub-agents, plugins, MCP and the Agent SDK. Every lesson ends with a quiz, and you should already have some development experience and know the basics of prompting.
What you'll learn
- How the Claude Code harness works around the model
- Giving Claude project context with CLAUDE.md files
- Controlling autonomy with permission modes, effort levels and model choice
- Automating repeated tasks with custom skills and hooks
- Splitting work across sub-agents and agent teams
- Connecting external tools through plugins, MCP and the Agent SDK
