Edit/update an existing image based on the provided image path and edit description.

**Usage**: `/update <image_path> <edit_description>`
**Example**: `/update /heroes/camelot/photos/portrait.jpg add a mystical staff in his hand`

Follow these steps:

1. **Configuration Check**: First verify that Gemini API is properly configured using `mcp__nano-banana-mcp__get_configuration_status`

2. **Image Path Validation**: 
   - Parse the first argument as the image path
   - Verify the image file exists and is accessible
   - Extract the remaining arguments as the edit description
   - If no image path provided, check if there's a recent image using `mcp__nano-banana-mcp__get_last_image_info`

3. **Context Discovery**: Based on the image location and edit description, gather relevant context:
   - If image is in `/heroes/` directory, load character description
   - If in `/locations/` or `/cities/`, load location context
   - If in `/items/`, load item specifications  
   - If in `/creatures/`, load creature details
   - Search for applicable settings in `/settings/` directory
   - Load world information from `/worlds/` directory if applicable

4. **Entity Analysis**: Parse the edit description to identify:
   - Changes requested (add, remove, modify elements)
   - New elements to be introduced
   - Style preferences or requirements
   - Lighting or mood adjustments
   - Technical specifications needed

5. **Edit Prompt Generation**: Create a professional edit prompt following `@docs/prompting-guide.md` editing templates:
   - **Adding/Removing Elements**: "Using the provided image of [subject], please [add/remove/modify] [element] to/from the scene. Ensure the change is [integration description]."
   - **Inpainting**: "Using the provided image, change only the [specific element] to [new element]. Keep everything else exactly the same, preserving the original style, lighting, and composition."
   - **Style Transfer**: "Transform the provided image into [artistic style]. Preserve the original composition but render it with [stylistic elements]."
   - **Detail Preservation**: "Using the provided image, [edit request]. Ensure that [critical details] remain completely unchanged. The modification should [integration requirements]."

6. **Settings Integration**: Apply appropriate settings for consistency:
   - Maintain character clothing styles if character is present
   - Preserve world-specific aesthetic elements
   - Apply environmental settings for background consistency
   - Include weapon/item styling if applicable
   - Maintain magical effects consistency

7. **Reference Image Handling**: Determine editing approach:
   - If editing a specific image file: use `mcp__nano-banana-mcp__edit_image` with the image path
   - If continuing work on the last generated image: use `mcp__nano-banana-mcp__continue_editing`
   - Include additional reference images if needed for style transfer or element addition

8. **Image Generation**: Execute the edit using the appropriate MCP tool:
   - `mcp__nano-banana-mcp__edit_image` for specific file edits
   - `mcp__nano-banana-mcp__continue_editing` for iterative improvements

9. **File Management**: Upon successful generation:
   - Save updated image in the same directory structure
   - Create versioned filename if preserving original
   - Archive the successful edit prompt in corresponding `/prompts/` directory
   - Update any cross-references if relationships changed

10. **Documentation**: Create a markdown file in `/prepared_prompts/` directory documenting:
    - Original image path and edit description
    - Final edit prompt used
    - Applied settings and context
    - Generated image path
    - Edit type and template used
    - Validation results

**Edit Types Supported**:
- **Element Addition**: Adding objects, characters, effects to existing image
- **Element Removal**: Removing unwanted elements while maintaining scene integrity  
- **Modification**: Changing colors, expressions, poses, clothing, etc.
- **Style Transfer**: Converting image to different artistic style
- **Inpainting**: Replacing specific parts while preserving the rest
- **Composition Changes**: Adjusting framing, perspective, lighting

**Important**:
- The edit prompt must be in English regardless of input language
- Follow exact editing templates from `docs/prompting-guide.md`
- Preserve critical details mentioned in project files
- Maintain consistency with established character/location features
- Use appropriate MCP tool based on editing scenario
- Ensure proper file versioning to preserve original if needed
