Meet Claude — what it is and who makes it

The concept

Claude is a assistant built for long documents and careful reasoning made by Anthropic. The models behind it are the Claude model family, including the fast Haiku, the balanced Sonnet and the largest for hard reasoning. None of that matters on its own — what matters is that you know what kind of worker you have hired. At reading something long and answering a narrow question about it without losing the thread is the job you hand it. When you want it to be reckless — it will decline, hedge, or ask what you mean is the job you keep.

Most people come to a course like this expecting a list of magic words. There is no such list. What there is, is a tool that produces careful, well-structured prose that usually respects the limits you set, and produces it at a speed no human matches — which means the skill is not in writing the prompt, it is in knowing what a good answer looks like so you can tell the difference.

Here is the first thing to try, worded the way you will word things for the rest of the course:

Read the answer twice. The first read is for the content; the second is for the shape — did it answer the question you asked, or the question it found easiest? That second read is the habit this whole course is built on.

Here is my current resume and a job description for a role I want. Tell me the five things the posting asks for that my resume does not prove, and for each one say whether I could realistically build that proof in three weeks.
