This is the first real end-to-end build of the course. We're adding a tiny tasks feature to the template: create a task, list your tasks, mark one complete, and delete one. The feature touches the database, the Rails backend, and the React frontend — which makes it the perfect shape for a first build.
But the real lesson isn't the tasks feature. It's the rhythm: describe what you want, let Claude draft it, review what it's about to do, run it, iterate through whatever breaks. This loop is the job, and every feature you'll ever build follows the same pattern.
- Setting a clear intent before writing any code
- Describing a feature to Claude Code in plain language
- Reviewing and steering Claude's plan before it writes anything
- Reading errors and iterating — the most important skill in the whole build loop
