Documentation

README

Excerpt

Video Thumbnail Generator

Use this skill to create a high-clarity thumbnail or cover image from the actual video content.

Non-Negotiables

Use the real video as visual evidence.
- If the thumbnail shows a person, product, UI, frame, or scene from the video, extract or inspect real frames.
- Never invent a generic software interface, fake product screen, or unrelated person.
Read style references before recommending styles.
- Use references/thumbnail-styles.md and references/thumbnail-style-recipes.md.
- Only offer style directions supported by those references or by the user's explicit instruction.
Keep text short and readable.
- Usually 2-5 words.
- Avoid thin type, low contrast, small labels, and clutter.
