Fashion Colorize Shell

Overview

Generate "line sketch -> realistic product render" outputs for outdoor shell jackets. This skill keeps sketch structure while applying a product-shot style (single garment, front view, white background, realistic hardshell material).

Workflow

1. Collect inputs:
   • Required: sketch image path
   • Required: brief text (material, color, fit, key design intent)
   • Optional: style reference image path
2. Run the local script:
   • uv run {baseDir}/scripts/run_colorize.py --sketch "<path>" --brief "<text>" --output-dir "<dir>" [--style-ref "<path>"] [--count 3]
3. Return generated file paths.
4. For revisions, keep previous output as style input and add explicit changes in --brief.

Input Guidance

• Good brief example:
  • 三层压胶硬壳材质，凯乐石薄荷绿，女性剪裁，强调胸前斜插袋和袖口调节。
• If the user wants "technical flats", do not use this skill's default product-shot look. Ask whether they want a separate technical drawing workflow.

Output Rules

• Default output is ecommerce-like product render:
  • Single garment
  • Front view
  • White background
  • No model, no scene, no text overlays
• Preserve key lines from sketch:
  • Hood shape
  • Center-front zipper/placket logic
  • Pocket placement direction
  • Cuff and hem adjustment zones

Fixed Runtime Defaults

• API base URL: https://models.kapon.cloud
• Model preference: gemini-3-pro-image-preview-2k (auto-fallback to gemini-3-pro-image-preview if upstream fails)
• API key is never embedded in this skill. User must provide GEMINI_API_KEY in environment.
