youtube-thumbnail skillA
youtube-thumbnail is agent-read markdown (skill) from naveedharri/benai-skills: Generate on-brand YouTube thumbnails for Ben van Sprundel using Higgsfield in one shot. Use when the user says create a thumbnail, make a YT thumbnail, thumbnail for video, generate ben thumbnail, variation of last thumbnail, or shares a video concept and asks for a thumbnail. Auto-infers mode from the inputs (variation, new-with-ben, ben-plus-other, no-face), defaults to 3 variants, asks at most one question. On topic-driven runs it first researches what is working in the niche (VidIQ preferred.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# YouTube Thumbnail Generate
One-shot thumbnail generation. Takes a concept (plus optional reference image and count), infers everything else, ships 3 variants and a manifest.
## Inputs
Two things, ideally both in the user's first message:
1. **Concept**: what the thumbnail should show. A sentence or phrase. ("Claude Code Skills, why it changes everything for solo founders")
2. **Reference image(s)** (optional but recommended, may be multiple): a past thumbnail, a photo of Ben, a second subject, a style anchor, a real logo PNG, or any combination. Determines the mode AND all of them must be passed into the generation. Never silently drop a user-supplied reference; if they gave you one, it must end up in `medias[]`. If they gave you a LIST, read EVERY image in the list, then pass every relevant one (don't pre-select just one). Every reference image MUST be visually read with the `Read` tool before the prompt is built (see rule 2).
