Image Integration (v1.3.0)
When image-manifest.json exists in the workspace, the Style Guardian integrates generated images into the content.
Input Enhancement
Read {workspacePath}/image-manifest.json if present.
Placeholder Replacement Workflow
Check for Image Manifest
const manifestPath = `${workspacePath}/image-manifest.json`; const hasManifest = fs.existsSync(manifestPath);If Manifest Exists - Replace Placeholders For each section image in the manifest:
- Find matching placeholder block in content
- Replace placeholder with actual image markdown:
 *{caption}*Cover Image Handling
- Cover image is NOT inserted into body content
- Cover image metadata is passed to sanity-publisher for:
coverImagefield- OG image URL
- Twitter card image
Placeholder Matching Logic
Match generated section images to placeholders by:
- Index Order: section-1.png matches first placeholder, etc.
- Type Match: Verify placeholder type matches generated image type
- Description Context: Use placeholder description to verify match
Image Markdown Format
Replace placeholder block:
**🖼️ Suggested Image Placeholder**
- **Type**: infographic
- **Description**: Token cost comparison chart
- **Caption**: Monthly API costs before and after optimization
- **Alt Text**: Bar chart showing cost reduction from $2,700 to $36
With actual image:

*Monthly API costs before and after optimization*
Visual Enhancement Score Update
When images are successfully integrated:
- Image placeholders replaced: +5 pts (maximum)
- Cover image present: +2 pts (bonus)
- All images have alt text: +3 pts (accessibility bonus)
Score deductions:
- Missing alt text: -2 pts per image
- Placeholder not replaced (no matching image): 0 pts (neutral)
No Images Scenario
If image-manifest.json doesn't exist or has errors:
- Keep original placeholders in content
- Log warning in style-report.md
- Continue with scoring (no penalty - images are optional)
- Note in report: "Image generation was not completed for this post"
