Resize PNG/JPG/WebP images into AVIF and WebP srcset variants (EXIF-rotated, never upscaled), a fallback <img> file and a base64 LQIP placeholder, then print a copy-paste <picture> snippet with truthful srcset widths. Cached per source. Use for site images, hero art, gallery screenshots, srcset, page-weight or LCP work, or reprocessing after swapping an asset.
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
## Run
CLI (one or more files, `file://` URLs, or folders; folders are not recursive):
```bash
node "${CLAUDE_PLUGIN_ROOT}/bin/atelier" images src/hero.jpg --out public/img --alt "Harbor at dusk" --base-url /img/ --loading eager
node "${CLAUDE_PLUGIN_ROOT}/bin/atelier" images src/gallery --out public/img/gallery --widths 480,960 --json
```
On Windows in Git Bash, put `MSYS_NO_PATHCONV=1` in front of `node` when you pass `--base-url /img/`. Otherwise Git Bash rewrites `/img/` to `C:/Program Files/Git/img/` and the CLI stops with a usage error. With it set, give file paths as relative or `C:/...` paths, not `/c/...`. Do not use `//img/`: that is a protocol-relative URL.
JS API (the module path is passed as an argument, so the import works on Windows, macOS and Linux):
```bash
node --input-type=module -e "const { pathToFileURL } = await import('node:url'); const m = await import(pathToFileURL(process.argv[1]).href); const result = await m.processImage({ input: 'src/hero.jpg', outDir: 'public/img' }); console.log(m.buildPictureSnippet({ ...result, alt: 'Harbor at dusk', baseUrl: '/img/' }));" "${CLAUDE_SKILL_DIR}/index.mjs"
```

How to install
mdr add ethany33/atelier/responsive-image-pipeline@sha256:5211ee75498ac57aThe line at the top of this page pins the label git:20260923.2ae2b1b, 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.
