Portable Agent Skill that turns a visual brief into a precise prompt for image generation or editing
Craft Image Prompts is a portable Agent Skill that writes precise prompts for image generation and editing, adapted to the target model. It is tagged for Hermes Agent but documented for Codex and ChatGPT.
What Craft Image Prompts does
Craft Image Prompts is a portable Agent Skill that turns a rough visual brief into a model-ready prompt. It covers generation, editing, compositing, variation and data-visualization requests, and adapts its approach to GPT Image, Gemini, Midjourney, Flux, Stable Diffusion or SDXL, Adobe Firefly, or an unknown model. It handles reference images, visual continuity, exact on-image text and negative prompts.
By default the output is one clean English prompt, or a structured JSON object holding the brief, constraints and a final_prompt_string. It avoids generic filler such as 'cinematic', adds technical detail only when it improves the result, and keeps factual charts honest by refusing to invent values, labels or sources. When a missing detail would change the result, it asks at most three questions. It is a prompting skill only, so you run the prompt in the image model you choose. The repository holds SKILL.md, a model-adaptation reference and Codex metadata.
