anthropics/courses — reverse-engineered prompt

Build me a beginner friendly set of hands on courses for learning how to use Claude, mostly as interactive notebooks with simple explanations and runnable examples. I want it to feel like a guided learning path, starting with the basics of getting an API key, making calls, choosing model settings, working with images or other multimodal inputs, and streaming responses. Then move into prompt engineering, more realistic business style prompts, ways to evaluate prompt quality, and finally how to use tools in Claude workflows.

Please make it easy for a student to follow in order, with short readme style instructions for each course, practical exercises, and examples that keep costs low by default. Assume the learner is new to this, so the tone should be approachable and not too academic. If there are choices to make, prefer the cheapest reasonable model for demos, but leave room to switch models. Look up current Anthropic docs online if you need to fill in any gaps.
