Designs and briefs high-CTR thumbnails and writes the A/B test plan: a thumbnail is a promise, not a poster, designed as a unit with the title and legible on mobile. Uses the CLICK framework.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

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

if [ -e ~/.agents/skills/'thumbnail-design' ] || [ -L ~/.agents/skills/'thumbnail-design' ]; then echo 'A skill folder named thumbnail-design already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/social-media-skills/skills' "$d" && git -C "$d" checkout --quiet 'f28cef2b7067ec64e79c9d85421c022c06659e03' -- 'skills/thumbnail-design' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/thumbnail-design' ~/.agents/skills/'thumbnail-design' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'thumbnail-design' ~/.claude/skills/'thumbnail-design' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
