What This Skill Does

Generates YouTube thumbnails at 1280x720 via the each::sense API. Supports styles like reaction faces, before/after splits, listicles, gaming, and product reviews. Uses session IDs to maintain consistent channel branding across multiple requests.

Dedicated thumbnail prompting with built-in CTR-focused defaults removes the trial-and-error of adapting general image generators to YouTube's specific format and feed constraints.

When to use it

  • Generating a shocked-face thumbnail for a viral reaction video
  • Creating a before/after split thumbnail for a room makeover video
  • Producing a consistent thumbnail series for a tech review channel
  • Rapidly testing two or three thumbnail variations before publishing
  • Building a gaming channel thumbnail with RGB and action composition

Example Workflow

Here's how your AI assistant might use this skill in practice.

  3. 3Includes prompt specifying exaggerated shock expression, bright yellow and red background, and text space on the right
  4. 4Sends the request and streams the server-sent event response
  5. 5Returns the generated 1280x720 thumbnail image
OUTPUT

A high-contrast 1280x720 thumbnail image with a shocked face and clear right-side space for text overlay
