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, and asks at most one question. Uses reference images as the identity anchor…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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 has to end up in `medias[]`. If they gave you a LIST, read EVERY image in the list, then pass every relevant one to `medias[]` (don't pre-select just one). Also: every reference image MUST be visually read (via the `Read` tool on the file path) before the prompt is built, so the prompt captures each reference's actual style, texture, palette, composition, and recurring motifs rather than relying only on the style spec defaults.

How to install
mdr add naveedharri/benai-skills/youtube-thumbnail-generate@sha256:57baa3e62ea62340The line at the top of this page pins the label git:20260916.a3b1e15, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
