Generate and edit finished YouTube thumbnail images from video topics, titles, scripts, and reference photos. Use for thumbnail creation, redesigns, and A/B variants with strong visual hooks and readable composition. Excludes downloading existing thumbnails and fixing thumbnail-saving extensions.
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 Deliver a real image using the built-in image-generation tool. A successful thumbnail communicates the video's specific promise at a glance, fits its audience, and survives a small preview. Concepts or prompts alone are deliverables only when the user asks for them. ## Get enough context to act Use the conversation's topic, title, audience, payoff, and supplied assets. A clear topic is enough to begin. Ask only for missing information that prevents a truthful, useful image; if there is no topic, ask what the video is about. Do not replace it with a generic "My Next Video." Respect exact copy, requested style, brand conventions, no-text requests, and variant count. For a video link, inspect accessible title/transcript information before claiming to know its contents. If inaccessible, use an already supplied summary or ask for the topic. Do not invent results or imply that you watched footage you could not access. …

How to install
mdr add blixvip/skills/thumbnail@sha256:3d443299b92e61dbThe line at the top of this page pins the label git:20260918.9d305f6, 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.
