SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Writing effective prompts for Qwen-Image and Qwen-Image-Edit in ComfyUI is error-prone: vague instructions produce poor edits, unquoted text renders incorrectly, and wrong CFG/step settings waste generation time. This Skill codifies the official prompting best practices so every generation or edit request follows proven structure. ## Core Features & Use Cases - Edit Taxonomy Guidance: Classifies requests into the six official edit types (add/delete/replace, attribute change, style transfer, text editing, tone adjustment, multi-image) and rewrites vague prompts into precise instructions. - Parameter Recipes: Provides CFG, step count, resolution, seed, and negative prompt presets for scenarios from quick composition tests to final print output. - ComfyUI Workflow Wiring: Documents how to patch positive_prompt slots in workflows like qwen_multiref_3img.json and validate them before queueing. - Use Case: When asked to "make it like Ghibli", the Skill rewrites it to "Keep the girl's pose and clothing unchanged, transfer the image to Studio Ghibli anime style, soft pastel colors, hand-drawn texture, cinematic composition" with CFG 4.5 and 50 steps. ## Quick Start Use the prompt-best-qwen skill to write an optimized positive and negative prompt for editing this image with Qwen-Image-Edit in ComfyUI.

FAQPage Schema
How do I write prompts for Qwen-Image-Edit in ComfyUI?▼

Write 1-3 concise sentences with the subject first, explicitly state the edit type (add, delete, replace, style, text), and specify position and attributes. Quote any text to render in double quotes and keep the prompt under 200 words.

What CFG and steps should I use for Qwen-Image generation?▼

Use CFG 4.0-5.0 with 40-50 steps for general and portrait generation, which is the recommended sweet spot. For text-heavy or product images, raise CFG to 7.0-10.0 with 50-60 steps to prioritize spelling accuracy.

How do I edit text in an image with Qwen-Image-Edit?▼

Quote the exact string and its location, for example: replace text 'Hello' at top-left with 'OPEN', keep original font style and color. For small or obscured characters, use chained editing with red/blue box markers across multiple passes.

Does Qwen-Image-Edit support multi-image reference workflows?▼

Yes, multi-image editing requires explicitly naming which image each element comes from, such as keeping the subject from image 1 and the style from images 2 and 3. Vague references like 'picture 1' without element naming produce unreliable results.

Why does Qwen-Image misspell text in generated images?▼

Text rendering fails when the text is not enclosed in double quotes or when CFG is too low. Always quote the exact string, specify its position and style, and use CFG 7.0-10.0 for text-heavy images to raise spelling accuracy.
