What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'image-optimization' ] || [ -L ~/.agents/skills/'image-optimization' ]; then echo 'A skill folder named image-optimization already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/hashgraph-online/awesome-codex-plugins' "$d" && git -C "$d" checkout --quiet '6d2e63f73f845eb5dd94c1debba627d4b6e32fba' -- 'plugins/IgorVaryvoda/image-optimization-skill/skills/image-optimization' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/IgorVaryvoda/image-optimization-skill/skills/image-optimization' ~/.agents/skills/'image-optimization' && rm -rf "$d"; fi

For Claude Code: ln -s ~/.agents/skills/'image-optimization' ~/.claude/skills/'image-optimization' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
