Compresses images to WebP (default) or PNG with automatic tool selection. Use when user asks to "compress image", "optimize image", "convert to webp", or reduce image file size.
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
# Image Compressor
Tool auto-selection order: sips → cwebp → ImageMagick → Sharp.
## Script Directory
`{baseDir}` = this SKILL.md's directory. Resolve `${BUN_X}`: `bun` if installed; else `npx -y bun`; else suggest installing bun. Replace `{baseDir}` and `${BUN_X}` with actual values.
| Script | Purpose |
|--------|---------|
| `scripts/main.ts` | Image compression CLI |
## Preferences (EXTEND.md)
First found wins:
| Priority | Path | Scope |
|----------|------|-------|
| 1 | `.baoyu-skills/baoyu-compress-image/EXTEND.md` | Project |
| 2 | `${XDG_CONFIG_HOME:-$HOME/.config}/baoyu-skills/baoyu-compress-image/EXTEND.md` | XDG |
| 3 | `$HOME/.baoyu-skills/baoyu-compress-image/EXTEND.md` | User home |
If none found, use defaults. **EXTEND.md supports**: default format, default quality, keep-original preference.
## Usage
```bash
${BUN_X} {baseDir}/scripts/main.ts <input> [options]
${BUN_X} {baseDir}/scripts/main.ts image.png # → WebP, replaces original
${BUN_X} {baseDir}/scripts/main.ts image.png -f png --keep # keep PNG format and original
${BUN_X} {baseDir}/scripts/main.ts ./images/ -r -q 75 # directory, recursive
```

How to install
mdr add jimliu/baoyu-skills/baoyu-compress-image@sha256:e93d107e4ffa1c27The line at the top of this page pins the label v1.56.1, 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.
