Strengthen an approved MiniMax H3 T2VA, I2VA, FL2VA, L2VA, or Ref2VA prompt with production contracts, forbidden outcomes, reference anti-leak roles, causal action phases, A/B invariants, and downstream QA gates. Use after or alongside MiniMax's official h3-prompt-writing skill; this skill does not replace the official current H3 schema. Use video-generation for the surrounding production and install-minimax-h3-local for runtime operation.
