Skill Design
How to design reusable AI video skills with SKILL.md
A reusable prompt skill is not just a good prompt. It is a protocol: what problem it solves, what minimum input it needs, what defaults it assumes, what it refuses to generate, and what output shape it guarantees.
What this repository encodes
Each production skill in this repository states the problem, minimum input, missing-field behavior, default workflow, batch-mode boundary, final output format, and generation constraints. The shared baseline centralizes rules that should not drift across skills.
Why this matters
Without structure, prompt systems become prompt piles. They become hard to maintain, hard to route, and easy to regress. A stable `SKILL.md` format makes the workflow legible to both humans and AI agents.
Chinese summary
如果一个视频 prompt 体系离开作者本人就不会用了，那它不是 skill，只是个人手感。这个仓库的价值之一，就是把手感固化成可复用协议。
