anthropics/claude-cookbooks ? reverse-engineered prompt

I want to build a project that's like a cookbook or a showcase for all the cool things you can do with the Anthropic Claude API. It should be a collection of Python examples, probably in Jupyter notebooks. I want to see how to do fundamental AI tasks like text classification and summarization. But also include more advanced stuff, like how to get Claude to answer questions using external knowledge from Wikipedia or a PDF I upload.

Show me how to use its vision capabilities to read charts and graphs, or pull information out of a form. I'd also love to see some examples of tool use, like building a simple customer service agent that can use external tools, or connecting it to a database to answer questions with SQL. Basically, I want a comprehensive set of recipes that I can learn from and copy code from to build my own Claude-powered apps.
