Anthropic’s free Claude Code in Action course packs 15 video lectures into about an hour, walking you from setup to advanced features like MCP servers and GitHub integration. You sign up with an email at anthropic.com/learn and get lifetime access. The modules cover everything from installing Claude Code and initializing projects to managing context with /init commands, Claude.md files and @mentions. You also learn to switch between Plan Mode and Thinking Mode, build custom commands for repetitive tasks, and hook into the Claude Code SDK for deeper automation. Midway through, the course drops in a satisfaction survey but keeps moving into hooks and the SDK section, where you see how to write and configure hooks—and learn common pitfalls that can block tool calls if you misconfigure conditions. The final step is an 8-question quiz you must pass to earn the completion certificate. I breezed through the videos but missed one hooks question, scoring 7/8 (87%). Anthropic emails you a PDF certificate with your name, course title, date and unique verification number moments after you pass. Once you’ve got the certificate, you can add it to LinkedIn in one click. It’s a simple way for engineers to prove they know Claude Code’s core tools—file manipulation, command execution, context control and PR automation—without spending much time or money. Whether you’re new to Claude Code or already have some experience, the structured walkthrough highlights capabilities you might not have tried yet.
