baoyu-compress-image

This Claude Code skill compresses images to WebP, PNG, or JPEG formats using the best available system tool, automatically selecting between sips, cwebp, ImageMagick, and Sharp. Use it when users request image compression, file size reduction, or format conversion, with configurable quality levels and batch processing capabilities for single files or directories.

# 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)
```

## Extension Support

Custom configurations via EXTEND.md. See **Preferences** section for paths and supported options.
