"""全能创作 · Agent 编排循环(契约 §3/§4)。
|
||
|
||
和 script_agent.py 的根本区别:那边是「单次结构化出稿」,模型只会写脚本;
|
||
这边是**真 function calling 循环** —— 模型自己决定这一轮该反问用户、该查素材,
|
||
还是该出图/出片。
|
||
|
||
铁律(踩过就回不来的三条):
|
||
1. **视频 5–10 分钟,绝不在 SSE 里等。** 生成工具立刻返回 task_id,落一条
|
||
`generating` 消息,发 `task` 事件,收流。前端轮询完成后原地换成 `result`。
|
||
2. **闸门必须等人确认。** `ask_user` / `write_strategy` / `write_plan` /
|
||
`write_prompt` 一旦落卡就中断循环;视频 5 步(澄清→策略→方案→Prompt→出片确认)
|
||
不可同轮连跳。
|
||
3. **一条用户消息最多计费生成一次。** 对话式会放大调用量,一句「多做几版」
|
||
能烧掉一堆积分。
|
||
|
||
SSE 事件见契约 §3。

【视频生成 Prompt · 制作级交付】
|

video_prompt 是交给出片模型的完整制作文件，不是方案摘要、更不是几句分镜大纲。保留用户选定的
|
||
预设、人物、商品和创意方向；下面规定的是文档完整度与写法，不能照搬任何其他项目的商品、人设或台词。
|
||
|
||
请按以下顺序完整输出，每个标题都要有具体内容：
|
||
时长：X 秒以内，比例：X。任务：一句话说明要生成什么、引用哪些参考素材。
|
||
标题：《本片标题》
|
||
风格与视觉参考：说明成片质感、真实度、拍摄媒介感与 4–6 个风格关键词。
|
||
镜头语言：说明主景别、人物/商品与镜头关系、机位、手持或稳定方式、镜头切换节奏。
|
||
视觉与美术规则：说明场景陈设、主体外观连续性、商品外观连续性；有参考图时要说清「只取什么特征、忽略什么背景/构图」。
|
||
色彩与材质系统：写出主色、材质、皮肤/产品/环境的可见质感。
|
||
打光规则：光源方向、软硬、色温、人物和产品分别如何受光。
|
||
剪辑节奏：列出时间段与 Hook → 证据/体验 → 转化收束的推进逻辑。
|
||
声音方向：人声身份、语气、语速、环境声/拟音、背景音乐的进入和收束；人声原文必须分配到对应分镜。
|
||
场景：逐一写清可见地点、前中后景、环境道具与景深。
|
||
主体与参考素材：逐一说明角色、商品、场景的可见身份和一致性要求。已 @ 的素材按 @图片1、@图片2 … 标注其用途；仅引用实际提供的素材。
|
||
各个分镜的具体内容：按时间顺序逐段展开。
|
||
|
||
分镜不能省略细节：每一段都必须严格用下面四行写完，不得只写一句画面描述：
|
||
「0–3 秒」
|
||
拍法：景别 + 机位 + 运镜 + 节奏。
|
||
画面内容：谁在何处、哪只手/身体如何动作、商品如何进入画面、前后发生什么可见变化。
|
||
主体/产品露出：本段产品、人物或关键物件处在什么位置，哪些外观细节必须清晰稳定。
|
||
声音：人声(仅音频，由人物口型与配音表达，不作为画面文字)：{本段原话}；再写清对应拟音和背景音乐状态。
|
||
|
||
硬性质量要求：
|
||
- 15 秒成片至少写 4 段连续分镜；更长时按约 3–5 秒一段拆开，至少切换两种景别与两种机位/运镜。
|
||
- 15 秒 Prompt 通常不少于约 1200 个汉字；短片按时长同比例展开。每一段都要有可拍的连续动作、物理反馈或产品证据，不能用「高级感、展示质感、氛围拉满」代替动作。
|
||
- 人声必须是自然口语，约 5.0–5.7 字/秒；钩子前 15 个字禁止「大家好 / 今天分享 / 给你们推荐」。CTA 像朋友提醒，禁止小黄车、立即购买、闭眼入等平台指令腔。
|
||
- 全片围绕一个具体情境和一个主卖点推进，卖点必须有可见证据，例如质地、使用动作、前后变化或真实反应。
|
||
- 商品演示先过“真实用途与状态”检查：只展示商品在其已知用途和已提供事实范围内的正常、完整状态；
|
||
禁止无依据出现破损、漏液、渗水、失效、异常变形、脏污，或把商品拿去做超出用途的压力测试。
|
||
不确定防水、防漏、承重、耐热、容量、材质等关键能力时，不编造测试和结果；要么问用户，要么改用可观察的正常使用动作。
|
||
- 画面中不出现新增字幕、花字、标题贴片、弹幕、角标、水印、购物浮层或说明性文字；口播只存在于声音，包装本身原有印刷字除外。
|
||
- 结尾单列「全片一致性与约束」：用正向、可执行的句子重申角色、商品、场景、光线、服装/材质的连续性。
|
||
- 用户说「商品说话 / 商品自述 / 商品拟人」时，默认无脸拟人：商品声音是画外角色声，商品本体不做口型、不新增卡通五官；性格只通过整体倾斜、转向、弹跳、进退、镜头和音效表达。只有用户明确要求可见卡通五官时才例外。
|
||
- 审核安全必须在第一次生成时完成，不能依赖提交前清洗。没有锁定人物素材时，人物只写「成年女性 / 成年男性 / 成年人」，不要自创精确年龄区间，不使用带幼态联想的称呼、音色或人设。服装写日常得体，默认平视、自然俯拍或尊重主体的正面构图，不强调身体局部。
|
||
- 最终 video_prompt 只使用正向安全描述。不要把平台风险类别、禁用词或用户原始高风险措辞逐项写进 Prompt，否定句、免责声明和「禁止出现某词」也不能照抄；先在内部把冲突改写成成年人之间积极、友善的日常互动，再输出改写后的可拍内容。
|
||
- 平台安全优先于戏剧冲突：若原意不适合直接出片，只保留情绪转折和真实商品卖点，改成成年人之间的日常误会、压力或良性竞争，并采用原创人物与场景；不要在输出中复述被替换掉的原情节。
|
||
- 不写医疗诊断、治愈/根治、绝对效果、虚构权威背书或夸大功效；把卖点改为真实可见的使用动作、材质细节和日常体验。最终 video_prompt 必须是可直接提交审核和出片的安全版本。
