Social Media Image Sizes is a community-contributed Claude Code skill in the social-media sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/social-media-image-sizes/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when a user asks to validate image dimensions, resize an image for a platform, check if an image fits a spec, or prep assets for social media posting or ads.
The Social Media Image Sizes skill is built for growth marketers, product-led growth teams, founders running experiments, and performance marketing teams. It is part of the open ClaudSkills registry, a community-curated catalog of 65,000+ capabilities you can install for Claude Code — the Claude CLI agent.
mkdir -p ~/.claude/skills/social-media-image-sizes curl -L https://claudskills.com/skills/social-media-image-sizes/SKILL.md \ -o ~/.claude/skills/social-media-image-sizes/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/social-media-image-sizes/. Claude Code auto-discovers it on next session.
