MiniMax H3 Prompting

Required skill stack

Every MiniMax H3 prompt uses this stack in order:

1. Story-Film canon, continuity, reference authority, approved dialogue/audio, and the source shot brief.
2. The selected ComfyUI workflow, which determines the H3 mode and actual runtime capabilities.
3. skills/h3-prompt-writing/SKILL.md, which is mandatory and controls final H3 field names, keyframe alignment, shot timing, speaker/dialogue syntax, and base-versus-Ref2VA section order.
4. Zero or one automatically selected H3 style skill from references/MINIMAX_H3_SKILL_ROUTING.md. Use more than one only when the user explicitly asks for a hybrid.
5. This Story-Film adapter's project-specific continuity, exact-audio, reference-scope, and capture constraints.

Story-Film runs python scripts/minimax_h3_skill_router.py --text "<brief>" automatically whenever the selected prompt adapter is minimax-h3; the user does not need to call h3-prompt-writing or a style skill separately. An explicit user selection of one of the eight style skills overrides automatic style classification but still returns through h3-prompt-writing, this minimax-h3 adapter, deterministic H3 format validation, and prompt-qc.

A style skill enriches content. It never replaces h3-prompt-writing, never changes the selected workflow, and never overrides Story-Film canon, reference authority, approved-audio authority, or workflow/runtime capability.
