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
