One prompt engineering pattern per day, delivered to your inbox for ten days straight. Each email gives you working Anthropic Python SDK code, before/after API output showing the difference the pattern makes, and a hands-on exercise.
You'll build a mixologist assistant from scratch. By Day 10 you'll be combining system prompts with structured output schemas, chain-of-thought reasoning with tool use, and multi-turn conversations with automated evaluation. Combining three or four patterns in a single API call feels natural.
Every lesson teaches a pattern you can use that day -- working code, concrete examples, and an exercise that fits in fifteen minutes.
