happyhorse — Claude Code skill: Alibaba video generation via belt CLI
Skill wraps four Alibaba HappyHorse 1.0 models through belt CLI: text-to-video, image animation, character preservation from references, and natural language video editing.
npx skills add 101-skills/superpowers --skill happyhorse -a claude-codeWhat happyhorse does
Contains wrappers for belt app run targeting T2V, I2V, R2V and Video Edit models. T2V builds a clip from a prompt, I2V animates a still frame, R2V keeps faces and figures from up to nine reference images, Video Edit rewrites backgrounds or objects from an instruction. All four output 720P or 1080P, up to 15 seconds.
Requires installed belt CLI (inference.sh) and an active belt login session. Commands fail without it. Pricing is $0.14 per second at 720P, $0.24 at 1080P; Video Edit bills input plus output duration.
What it helps with
- generate a video clip from a text scene description
- animate a still image with specified camera motion
- preserve a character's appearance from a reference in new footage
- replace background or object in existing video via text instruction
- get reproducible output with a fixed seed
Example prompts for the agent
- Generate a video: horse galloping across a meadow at sunset, 10 seconds, 1080P
- Animate frame
