AI Image Generation
This skill guides you on how to generate and edit images using the AI image generation service, helping users create high-quality product images, modify existing images, and perform creative visual transformations.
Core Concepts
The AI Image Generation tool produces new images based on a text prompt and optional reference images. It supports a wide range of use cases:
- Text-to-image: Generate a brand-new image purely from a text description.
- Image-to-image: Provide one or more reference images and a prompt to generate a new image that preserves elements from the references.
- Image editing: Modify specific elements, colors, backgrounds, or styles in an existing image.
- Product compositing: Place a product from one image into a scene from another image.
- Model swapping: Replace the model or mannequin in a product photo.
Reference images are strongly recommended when the user wants the output to closely resemble an existing product or scene. Up to 3 reference image URLs can be provided, separated by commas.
Parameter Guide
| Parameter | Required | Description | Default |
|---|---|---|---|
| prompt | Yes | Text description of the desired image. Supports text-to-image, image-to-image, editing, model swapping, and more. Max 1000 characters. | -- |
| referenceImageUrl | No | URL(s) of reference image(s). Separate multiple URLs with commas. Up to 3 images supported. Max 1000 characters. | -- |
| aspectRatio | No | Aspect ratio of the output image. | 1:1 |
Supported Aspect Ratios
| Value | Description |
|---|---|
| 1:1 | Square (default) |
| 3:4 | Portrait |
| 4:3 | Landscape |
| 9:16 | Vertical fullscreen |
| 16:9 | Horizontal fullscreen |
Prompt Writing Tips
- Be specific and descriptive: Clearly describe the subject, scene, lighting, style, and mood you want.
- Reference images by number: When using reference images, refer to them as "image 1", "image 2", etc., in the order they appear in
referenceImageUrl. - State the operation explicitly: Use clear action verbs like "replace", "change", "put", "combine", "generate".
- Keep within 1000 characters: Prompts have a maximum length of 1000 characters.
Prompt Examples by Scenario
Object replacement:
Replace the vase on the table in image 1 with a potted plantBackground color change:
Change the background color of image 1 to pure whiteProduct compositing:
Place the product from image 2 onto the marble countertop in image 1Style transfer:
Transform image 1 into the artistic style shown in image 2Text-to-image (no reference):
A professional product photo of a sleek black wireless headphone on a gradient blue background, studio lighting, 8K qualityModel swapping:
Replace the model in image 1 with a different model while keeping the same clothing and poseAPI Usage
This tool calls the LinkFox tool gateway API. See references/api.md for calling conventions, request parameters, and response structure. You can also execute scripts/multimodal_generate_image.py directly to run image generation.
Display Rules
- Show the generated image: When the response contains image content in the
textfield, display it directly to the user using markdown image syntax. - Status reporting: Check the
statusandfinishedfields. If image generation is still in progress, inform the user and advise waiting. - Prompt transparency: Briefly describe what prompt and parameters were sent so the user understands what was requested.
- Aspect ratio confirmation: If the user does not specify dimensions, use the default 1:1 ratio but mention it so they can request a different ratio if needed.
- Reference image guidance: If the user wants a result close to an existing image but did not provide a reference URL, proactively suggest they provide one for better fidelity.
- Error handling: When generation fails, explain the issue based on the response
statusfield and suggest adjustments (e.g., simplify the prompt, check reference image URLs, try a different aspect ratio).
Important Limitations
- Reference image limit: A maximum of 3 reference image URLs can be provided per request.
- Prompt length: The prompt must not exceed 1000 characters.
- URL validity: Reference image URLs must be publicly accessible. Private or expired URLs will cause failures.
- Aspect ratio options: Only 1:1, 3:4, 4:3, 9:16, and 16:9 are supported.
