MiniMax-H3
MiniMax-H3 is a collection of agent skills for AI-powered video generation with the MiniMax H3 model. The portable h3-prompt-writing skill provides prompt engineering guidance for text-to-video, keyframe-to-video, and reference-based video generation modes, packaged as Markdown instructions with reference guides. It works across any agent framework that reads SKILL.md files (Claude Code, Cursor, Windsurf, ChatGPT, LangChain) without requiring API calls. Eight additional style-specific skills (minimalist product ads, 3D animation, papercraft stop-motion, etc.) are bundled but require the MiniMax Hub canvas workflow.
