宝鱼·图片压缩

本技能由 Jim Liu (宝玉) 开源，用于在 AI Agent 中处理AI 图片压缩。以下为官方技能说明文档：

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.

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

${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

# 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.
