image-prompting

# Image Prompting Most image failures are prompt failures. This skill gives the MCP agent a repeatable structure for turning any user request into a prompt that renders clean typography, preserves layout on edits, and avoids AI slop. Defaults are tuned for **GPT Image 2** (best legible text), with fallbacks for Nano Banana, Grok Imagine, and CogView. ## Quick Decision Table Costs are what you are actually CHARGED, verified live. **Size is the biggest lever:** any dimension above 1024 moves GPT Image 2 to the large tier and roughly doubles the price ($0.064 → $0.127).
