The craft lessons from Fable 5's illustration pipeline generalize to AI interaction design: (1) natural language wins over notation: models respond to descriptions ('deep blue') not codes (#0000FF), (2) negations backfire: 'no red' activates red because the word primes the concept, (3) iteration beats perfection: sending a prompt, getting feedback, and refining produces better results than trying to craft the perfect prompt — these principles apply to prompt engineering for any generative model, suggesting that cross-modal craft knowledge is more transferable than domain-specific expertise would suggest
