name	minimax-h3-prompting
description	Write or refine prompts for MiniMax H3 video generation via comfy-agent (minimax_h3_t2v / minimax_h3_i2v / minimax_h3_r2v presets). Use whenever composing the --104_prompt for an H3 run, when a user asks for a video clip on an H3 environment, or when an H3 output missed the intent (wrong audio, ignored camera move, style drift, rushed pacing) and the prompt needs iteration.

Read docs/minimax-h3-prompting.md before composing any H3 prompt — it is the single source of truth.

Non-negotiables it enforces:

• H3 renders picture and stereo audio in one pass: always direct ambience and music explicitly, or the model invents them.
• Render the final block in the official three-field format (integrated_multimodal_description / overall_soundscape / non_diegetic_music), with the <Picture 1> alignment sentence for I2V or explicit <Picture 1> / <Audio 1> role assignment for R2V.
• Fit beats to the frame budget (--104_length: 124 ≈ 5 s → one beat; 243 ≈ 10 s; 362 ≈ 15 s → timecoded shot list).
• Iterate with a fixed --15_noise_seed; verify frames (ffmpeg) AND audio (ffprobe) before reporting results.
