muapi-youtube-thumbnail is agent-read markdown (skill) from samuraigpt/generative-media-skills: Design a high-CTR YouTube thumbnail — striking imagery, bold text placement, and emotional face/subject if needed..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add samuraigpt/generative-media-skills/muapi-youtube-thumbnail@v1.0.0mdr add samuraigpt/generative-media-skills/muapi-youtube-thumbnail@sha256:c5a8a08d04c0b989Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever.
