A great prompt is not magic. It's specification.
Click through a production-grade prompt, part by part, and see exactly what each COSTAR element contributes — and what silently breaks when you skip it.
A real prompt — click any part
What is the COSTAR prompt framework?
COSTAR structures a prompt into Context, Objective, Style, Tone, Audience and Response format — six explicit decisions that turn a vague request into a reliable specification.
Is prompt engineering still a real skill?
The magic-words era is over; the specification era is not. Engineers who can state context, objective and output contract precisely get consistently better results from any model.
How does miatz teach prompting?
In the Prompt Craft Lab, learners write prompts against real tasks and get scored on COSTAR and canonical technique, with an optimized rewrite and rationale every time.

Now lint it against a real model's official rules
Anatomy teaches what a well-formed prompt contains. Prompt X-Ray grades yours against the target model's own published guidelines — every finding with a receipt, free, no signup.
