Produces three distinct high-CTR YouTube thumbnail concepts per video - each a full spec with focal point, precise facial-expression direction, text overlay copy, color and background direction, and two paired title variants. Use when someone says "I need a thumbnail idea", "why is my CTR low", "help me pick a thumbnail and title", or is planning a video before filming and wants the click package designed first. Do NOT use for the spoken and visual opening seconds of the video itself - use…
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.

This skill produces concrete thumbnail concepts before filming or design, so the creator enters production knowing exactly what click signal they are building toward.

How to install
mdr add skillmedev/creator-studio/thumbnail-concept@sha256:27034fbe819b47e0The line at the top of this page pins the label git:20261005.21980fd, 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.
