# Image Compressor
|
|
|
|
Compresses images using best available tool (sips → cwebp → ImageMagick → Sharp).
|
|
|
|
## Script Directory
|
|
|
|
Scripts in `scripts/` subdirectory. `{baseDir}` = this SKILL.md's directory path. Resolve `${BUN_X}` runtime: if `bun` installed → `bun`; if `npx` available → `npx -y bun`; else suggest installing bun. Replace `{baseDir}` and `${BUN_X}` with actual values.
|
|
|
|
| Script | Purpose |
|
|
|--------|---------|
|
|
| `scripts/main.ts` | Image compression CLI |
|
|
|
|
## Preferences (EXTEND.md)
|
|
|
|
Check EXTEND.md in priority order — the first one 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]
|
|
```
|
|
|
|
## Options
|
|
|
|
| Option | Short | Description | Default |
|
|
|--------|-------|-------------|---------|
|
|
| `<input>` | | File or directory | Required |
|
|
| `--output` | `-o` | Output path | Same path, new ext |
|
|
| `--format` | `-f` | webp, png, jpeg | webp |
|
|
| `--quality` | `-q` | Quality 0-100 | 80 |
|
|
| `--keep` | `-k` | Keep original | false |
|
|
| `--recursive` | `-r` | Process subdirs | false |
|
|
| `--json` | | JSON output | false |
|
|
|
|
## Examples
|
|
|
|
```bash
|
|
# Single file → WebP (replaces original)
|
|
${BUN_X} {baseDir}/scripts/main.ts image.png
|
|
|
|
# Keep PNG format
|
|
${BUN_X} {baseDir}/scripts/main.ts image.png -f png --keep
|
|
|
|
# Directory recursive
|
|
${BUN_X} {baseDir}/scripts/main.ts ./images/ -r -q 75
|
|
|
|
# JSON output
|
|
${BUN_X} {baseDir}/scripts/main.ts image.png --json
|
|
```
|
|
|
|
**Output**:
|
|
```
|
|
image.png → image.webp (245KB → 89KB, 64% reduction)
|
|
```
