YouTube thumbnail workflow: one promise, frames from footage, short outlined text, feed-size previews, A/B variants. Use when a video needs a thumbnail.
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
## Overview The thumbnail and the title are the whole pitch before anyone presses play. This skill is the video domain's thumbnail pipeline: decide the promise, get the best possible picture of it from the footage or a generated scene, put a real cut-out face or product on it, set two to five words of type with a renderer that measures and fits them, and check the result at the size people actually see it. It replaces drawing text onto frames with PIL or asking an image model to spell the headline, which give soft, misspelled, badly placed text. ## Mental model A thumbnail does one job: make one promise the video keeps, readable in under a second at about 360 px wide on a phone or 168 px in a sidebar. - The picture carries the emotion or the stakes: a face, a result, a before/after, the product in use. - The text adds what the title doesn't say. It never repeats the title. - Contrast, size, and placement decide whether it survives the feed; detail does not survive. …

How to install
mdr add muvon/octomind-tap/video-thumbnails@sha256:4e9c32d3b301800fThe line at the top of this page pins the label git:20261108.a3ce67a, 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.
