Use when optimizing images for SEO — alt text, filenames, formats, lazy loading, responsive sizing.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

<objective>
Checks image SEO fundamentals: descriptive `alt` text (empty only for decorative images), kebab-case descriptive filenames, modern formats (WebP/AVIF with JPG/PNG fallback), `loading="lazy"` on below-fold images, responsive `srcset`/`sizes`, explicit `width`/`height` to prevent CLS, ImageObject schema, and file-size/quality targets per image role (hero/content/thumbnail).
</objective>

# Image SEO

## Checks

- All `<img>` have descriptive `alt` (empty `alt=""` only for decorative)
- Filenames: kebab-case, descriptive (`red-running-shoes.webp` not `IMG_1234.jpg`)
- Formats: WebP/AVIF with JPG/PNG fallback
- Lazy loading: `loading="lazy"` on below-fold images
- Responsive: `srcset` + `sizes` for different viewports
- Dimensions: `width` + `height` set to prevent CLS

## File Optimization Targets

| Type | Format | Max size | Quality |
|------|--------|----------|---------|
| Hero | AVIF/WebP | 200 KB | 75-80 |
| Content | WebP | 100 KB | 75 |
| Thumbnail | WebP | 30 KB | 70 |

How to install

The exact contents, by fingerprint

mdr add fusengine/agents/seo-images@sha256:cd23aceafb97f44d

The line at the top of this page pins the label git:20260729.3b91eed, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
