Create readable, truthful video thumbnails and covers with Magic Hour, preserving supplied faces and products and testing composition at small display size. Use for YouTube thumbnails, Shorts covers, or episode covers, not a general product catalog set.
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
# Magic Hour thumbnails Make the actual topic legible in a small image. Visual drama is useful only if the viewer can identify the subject and the promised content exists in the video. Infer the hook from supplied content and recommend one composition; do not require a technical prompt or a long creative interview. Honor existing spending authorization and delegated creative decisions while respecting requested draft approvals. Show the finished cover first. For concept selection, editable headlines and series reuse, read [cover design](references/cover-design.md). ## Find the honest visual hook Read the supplied title, transcript, outline or footage. Choose one specific tension, comparison or outcome that it supports. Do not invent a result, reaction, endorsement, screenshot or person to make the cover more clickable. Use an authorized source image when face or product identity matters. …

How to install
mdr add magichourhq/skills/magic-hour-thumbnails@sha256:f25d6a0867c4f128The line at the top of this page pins the label v1.1.0, 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.
