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 DALL-E 3, Flux, and Nano Banana.
