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)

运行依赖

• 包内压缩脚本需要 bun，没有 Bun 时使用 npx -y bun；两者都不存在时只报告缺失，不改写原图。
• 检查方式：运行 bun --version，失败后再检查 npx --version。

完成标准

• 完成本 Skill 正文中 Mode、Output、Handoff 或最终交付步骤声明的全部适用产物，不因它处在较大任务中而缩减。
• 执行正文已有的检查清单、视觉检查、平台兼容检查或事实检查；不适用项说明理由，失败项先在本 Skill 内返工。
• 返回用户可直接使用或交给下一个完整 Skill 的独立产物，并明确仍需用户授权的外部写入。
