Included skills
Add these skills to your assistant as well. Then the agent follows the same instructions for every step.
Style sheet for brand and AI images
Condenses colours, fonts, imagery and no-gos from your brand material onto one page that also works as a brief for AI images.
Alt text for images
Writes short, factual alt texts from image descriptions and context so images make sense with a screen reader.
