H3 Prompt Writing

External Agent Runtime (Mandatory)

This skill is standalone for Claude, Codex, OpenCode, and other external Agent runtimes. Read references/platform-api.md and check LINGJING_API_KEY before any model call. All model calls must use the LingJing external /api/v1 API.

• Use scripts/lingjing_api.py when available, or make equivalent HTTP requests.
• Do not call Hub tools, Canvas APIs, localhost, X-Agent-Key, internal /api/ecommerce/*, or upstream model APIs.
• Write long rewrites and locked prompts to local Markdown files.
• If the user only wants a prompt, stop after the rewrite. Call the video API only when the user explicitly asks to generate the video.

Workflow

1. Identify the input mode: T2VA, I2VA, FL2VA, L2VA, or full-reference Ref2VA.
2. For base text/keyframe modes, read references/base-en.txt and follow its final prompt structure.
3. For full-reference mode, read references/ref-en.txt and follow its six-section rewrite format.
4. Preserve the exact field names, section order, labels, and timing notation from the selected guide.

Base Modes

• T2VA: build the full audiovisual timeline from text.
• I2VA: start from the first frame and develop forward from it.
• FL2VA: describe the continuous path between the first and last frames.
• L2VA: infer a plausible opening and converge to the supplied last frame.

Use integrated_multimodal_description, overall_soundscape, and non_diegetic_music in the order shown in references/base-en.txt.

Full-Reference Mode

Ref2VA rewrites use subject_definitions, summary, retention_analysis, detailed_description, overall_soundscape, and non_diegetic_music in that order. Reference labels stay consistent across all sections.

Read references/ref-en.txt for label rules, retention analysis, and complete examples.

Output Rules

• Write rewrite sections in English; preserve dialogue, lyrics, and visible scene text in their original language.
• Describe each shot by composition, subjects, environment, actions, camera, sound, and the exact point where referenced content appears.
• Avoid plot summaries, unresolved reference labels, and timing that does not match the requested duration.
