Readme
thumbnail-prompter
Claude Code slash command that analyzes reference thumbnails, silently learns the viral patterns, then generates custom image prompts for YOUR video topic.
Install (one command)
npx thumbnail-prompterThat's it. It copies the skill to ~/.claude/commands/ and it works globally in every Claude Code session.
Usage
/thumbnail-prompter ./path/to/thumbnailsWhat happens:
- It reads every image in the folder (Claude actually sees them — multimodal)
- Silently extracts the viral DNA — patterns, colors, composition, psychology
- Asks you: "What's your video topic?"
- Generates 3 paste-ready image prompts tailored to your topic using the patterns it learned
You get prompts ready for Midjourney, DALL-E, Ideogram, or Flux — not generic templates, but prompts that match the exact style of your reference thumbnails.
Example
/thumbnail-prompter ./youtube-saves
> I've analyzed 5 thumbnails and extracted the viral DNA patterns.
> What's your video topic or title?
