Choose how to use this skill
You do not need every option. Choose the path your AI client supports. The stable page stays the same; versioned files are immutable.
1. Native installer
This listing has no registered native installer command. Use the complete package or source fallback below, depending on what your client supports.
Do not guess an installer command or replace an existing version without reviewing the diff.
2. Complete package recommended
Download the ZIP when available. It includes SKILL.md plus the references, security notes and version metadata.
No complete ProSkills package is published for this listing yet.3. Prompt-only
Copy the prompt above when the agent can read the stable page or when you want to adopt the workflow without installing a skill.
Need only the instruction file?
Download SKILL.md only if your client requires a single file. The complete ZIP is safer for a full installation because it preserves the references and release context.
No path installs or executes anything by itself. Your agent still needs access to the project files. Before updating, compare the installed version and review the diff.

- Image-to-Image — Transform existing images with reference
- Inpainting — Edit specific regions with mask support
- Instruction-based Editing — Tell the AI what to change in natural language
- Multi-Resolution — 1024×1024, 1024×1536, 1536×1024, and custom aspect ratios
- Batch Generation — Generate 1–4 variations in one call
- Aspect Ratios — 1:1, 16:9, 9:16, 4:3, 3:4, and more
Usage Examples
Just talk to your agent:
"Generate a watercolor painting of a mountain sunset"
"Edit this photo to make it look like a vintage film still"
"Remove the background from this image and replace it with a beach"
"Create 4 variations of a logo design for a coffee shop"
The agent will guide you through missing details and handle generation.
