h3-prompt-writing — Claude Code skill: what it does, how to install
Transforms multimodal video generation requests into MiniMax H3 prompts. It structures base keyframe transitions and full-reference rewrites.
npx skills add MiniMax-AI/MiniMax-H3 --skill h3-prompt-writing -a claude-codeWhat h3-prompt-writing does
This skill translates video generation requests into the exact format required by MiniMax H3. It covers standard generation modes like T2VA, I2VA, FL2VA, and L2VA using structure from references/base-en.txt. When working with complex inputs, it follows the Ref2VA format from references/ref-en.txt.
Descriptions detail composition, camera paths, subjects, and audio layers for each shot. All prompt sections are written in English, while dialogue and visible scene text stay in their original language. The instructions reject vague terms like cinematic in favor of tangible visual details.
The skill runs entirely on local file reads, so external API keys or proprietary runtimes are unnecessary. The agents/openai.yaml file provides optional interface metadata without limiting the skill to a specific agent.
What it helps with
- Format multimodal requests into MiniMax H3 prompt structures
- Connect visual transitions between first and last keyframes
- Define soundscapes, background noise, and background music
- Maintain consistent reference labels across prompt sections
Example prompts for the agent
- Convert this story outline into a MiniMax H3 prompt using FL2VA mode
- Structure a Ref2VA prompt with reference tags <Picture 1> and soundscape details
- Draft an I2VA prompt starting from the provided keyframe with camera motion
