Minimax Worldbuilder — Development skill for Claude Code

minimax-worldbuilder

An agent skill for writing MiniMax-H3 video prompts.

H3 produces video and native 32 kHz stereo audio in a single pass, and it doesn't take free prose. The prompt is a structured format: named sections in a fixed order, fixed enum vocabularies for camera motion and reference retention, timestamped shot markers. Paraphrase a camera move and it gets ignored. Write a thin soundscape and the clip comes back nearly silent.

The skill handles the two full-prompt paths:

• Ref2VA, when reference images, video, or audio are supplied. Six named sections.
• T2VA, when there are no references at all. Three named fields.

It reads the references, extracts an inventory of the characters and the environment, picks a look, and writes the prompt in MiniMax's own format: `` / `` / `` / `` tags, `[Shot N]` cut timestamps, `(S1)` speaker IDs, `` dialogue blocks, and the soundscape sections H3 needs before it will generate any audio at all.

The keyframe paths (I2VA, FL2VA, L2VA) are out of scope. They need a first-frame alignment instruction this skill deliberately doesn't specify.
