You've asked it to write some code. You may have even let it refactor a file or two. But there's a good chance you're only scratching the surface. In this session, I'll share what I've learned from using Claude Code daily and teaching it to developers in workshops. We'll go into the features that change how you work. Things like shaping Claude's behaviour through CLAUDE.md, building your own commands and skills, automating feedback loops, and understanding the small configuration details that most people overlook. We'll also look at use cases beyond software development. We'll use Claude Code as an actual AI-assistant, not only a code-assistant. This isn't a getting-started guide. It's a tour of the parts of Claude Code that only become visible once you stop treating it like an autocomplete tool. If you use Claude Code but feel you're not getting the most out of it, this session will help you see what it can really do.
