Social Graphic Skill

Create polished social media graphics and visual assets optimized for specific platforms. This skill handles platform-specific dimensions, safe zones, and design constraints to produce assets that display correctly and perform well across channels.

When to Use

Invoke this skill when the user needs:

• Social media post images -- Twitter/X, LinkedIn, Instagram
• Newsletter headers -- Substack, email campaigns
• Blog feature images -- OG images, hero banners
• Course thumbnails -- Platform-specific cover images
• Profile and cover images -- Headers, banners, profile pictures

For YouTube thumbnails or any thumbnail requiring specialized CTR optimization, use the creator-stack:thumbnail skill instead.
