Prompting 101 | Code w/ Claude

25 minutesBeginnerPractitionerAnthropicPrompt Engineering

Anthropic. Two members of Anthropic's Applied AI team build up a single prompt for a real customer use case (analyzing Swedish car accident reports), starting from a one-liner that fails and adding role, task context, dynamic content, examples, and final emphasis one layer at a time. It is the cleanest demonstration on YouTube of the exact "role + context + task + constraints + format" stack the article describes, with the failure modes shown along the way.

AI Expert note

The demo uses Claude, but the layer-by-layer build maps one-to-one onto the article's role-context-task-constraints-format stack, whatever model you use.

What you should get from this

Build stronger prompts by adding role, task context, examples, constraints and output format one layer at a time.
