Generate Image
Generate an image for: $ARGUMENTS
Instructions
You are generating an AI image for an existing worldbuilding entity.
Step 1: Locate the Entity
Find the entity file based on the user’s input:
- If given a full path: Use that path directly
- If given just a name: Search in
Worlds/for matching entity files - If ambiguous: Ask the user to clarify which entity they mean
Read the entity file to extract the image prompt.
Step 2: Extract the Image Prompt
Look in the ## Image Prompts section of the entity file.
Entity templates have different prompt subsections. Common patterns:
- Characters:
### Portrait (Bust)and### Full Body - Settlements:
### Exterior Viewand### Interior View - Items:
### Display Viewand### In Use - Creatures:
### Natural Habitatand### Combat Pose - Geography:
### Landscape Viewand### Aerial View
Find the Prompt: field under one of these subsections. This is the filled prompt to use.
Prompt Selection Priority:
- If user specifies which prompt (e.g., “portrait”, “full body”, “exterior”), use that one
- If the entity has a Portrait/Bust prompt filled, prefer that
- Otherwise use the first filled prompt found
If no prompts are filled (only templates exist), inform the user that the entity needs its image prompts filled first.
Step 3: Prepare for Generation
Determine the filename:
- Use the entity name as the base filename
- Add
.pngextension - Save in the same directory as the entity file
Example: Worlds/Eldoria/Characters/Aldric the Bold.md -> Worlds/Eldoria/Characters/Aldric the Bold.png
Image Parameters for gpt-image-1.5:
- Size:
1024x1024(square, best for portraits and general use)- Or
1024x1536(portrait orientation) for full-body characters - Or
1536x1024(landscape) for geography/settlements
- Or
- Quality:
high(best detail for fantasy art) - Format:
png(best quality, supports transparency)
Step 5: Update the Entity File
After successfully generating and saving the image:
-
Add
image:field to frontmatter (if not present):image: "[[Entity Name.png]]" -
Insert image embed after frontmatter: Add
![[Entity Name.png]]on a new line immediately after the closing---of the frontmatter, before the# Title.
Example result:
---
tags: [character, protagonist]
name: "Aldric the Bold"
image: "[[Aldric the Bold.png]]"
status: complete
---
![[Aldric the Bold.png]]
# Aldric the Bold
...
Step 6: Confirm Success
Report to the user:
- Path where the image was saved
- Which prompt was used (e.g., “Portrait” or “Full Body”)
- Confirmation that the entity file was updated
- Suggest opening the file in Obsidian to see the embedded image
Optional: Generate Prompt from Entity
If the image prompt section is empty but the user wants an image, offer to generate a prompt based on the entity’s content:
- Read the entity’s description, appearance, and other sections
- Craft an appropriate prompt following the template format
- Fill in the prompt section
- Then proceed with image generation
Image Type Selection
Ask the user which image type they want if the entity has multiple prompt options:
For Characters:
- Portrait (bust, chest-up) – good for character sheets, NPC cards
- Full Body – good for reference sheets, action poses
For Settlements:
- Exterior View – the building/settlement from outside
- Interior View – inside a key room or area
For Geography:
- Landscape View – ground-level scenic view
- Aerial View – bird’s eye or map-like perspective
For Items:
- Display View – clean showcase of the item
- In Use – the item being wielded/used
Size Options:
| Orientation | Size | Use For |
|---|---|---|
| Square | 1:1 | Portraits, items, icons |
| Portrait | 2:3 | Full-body characters |
| Landscape | 3:2 | Geography, settlements, battles |
