Miniature World Short

Mission

用于微缩世界创意短片：以微型道具、模型场景和移轴摄影美学讲一个有情绪弧光的温柔小故事，适合节日祝福、生活故事、暖调情感短片。

JarvisHub Execution Model

• 主 Agent 负责编排：读取画布事实、整理任务 brief、按阶段同步 TodoWrite 进度，并把已确认的文本成果写入画布；媒体生成、等待、拼接和评审交给具备相应能力的执行 agent 或当前可用工具。TodoWrite 不是画布写入前置条件。
• 图像、视频和拼接交给具备媒体能力的执行 agent：brief 给出稳定输出身份、用途、真实参考 URL 和关键约束；需要下游引用时必须等待真实 imageUrl / videoUrl，不能把提交态当完成态。
• 多模态验收交给 critic sub-agent：只读取真实媒体并评审，不生成、不补素材。
• 当前已知 canvas 工具集没有通用音频生成、音频驱动口型、末帧抽取或视频直改工具；旁白、BGM、字幕、末帧承接和精准 lip sync 只能作为后期合成计划或 blocked 项，除非本轮工具列表明确暴露对应能力。

When To Use

Use this skill for:

• miniature world stories,
• tilt-shift model-scene films,
• tiny character emotional shorts,
• holiday blessing videos,
• warm 60-90s social shorts,
• handcrafted miniature scene storytelling.

Do not use it for real documentary, regular drama, or wool felt full-size animation.

Canvas-Native Boundary

Follow the JarvisHub Execution Model. Do not assume a fixed model menu, membership state, or exact duration support. If exact ratios/durations are unsupported, disclose and provide closest runnable prompts.

Required Intake

Confirm first:

• aspect ratio: default 9:16, alternatives 16:9 or 1:1.
• duration: 60s, 90s, or custom.
• target resolution supported by this turn's tool list.
• story theme or greeting occasion.
• whether there is narration.
• visual tone: warm/soft, cool/moonlit, festive, nostalgic, playful.
• image/video model preference only if the harness exposes choices.

Do not plan the story before these production specs are known.

Workflow

1. Confirm production specs.
2. Build story arc.
3. Design key elements.
4. Generate character/scene/prop references.
5. Generate shots in storyboard order.
6. Plan BGM/narration if needed; generate real audio only if this turn exposes a real audio tool.
7. Assemble rough cut and review.
8. Final output.

Pause after specs, storyboard, elements, completed clips/audio plan or assets, and rough cut.

Story Structure

Build 4-6 story beats:

• establish miniature world,
• trigger event,
• action/progress,
• emotional high point,
• afterglow ending.

Each beat should define:

• scene,
• characters,
• key action/prop,
• emotion.

Typical 60s film: 10-12 shots. Typical 90s film: 14-18 shots.

Miniature Visual Rules

All images and video should feel like miniature model photography:

• tilt-shift shallow depth of field,
• strong foreground/background scale separation,
• delicate material texture,
• tiny props and model-scale environments,
• soft diffused light,
• warm cream/tea/gold or cool mint/moonlight palettes.

Characters:

• miniature figure scale,
• slightly stylized but emotionally readable,
• consistent clothing/hair across shots.

Scenes:

• model-like streets, rooms, tables, gardens, workshops,
• fixed prop placement,
• handmade material detail.

Props:

• core story props get their own element.
• oversized props require multiple characters to move them.
• avoid impossible glowing/floating props unless the story is explicitly magical.

Shot Rules

Each shot should include:

• shot ID,
• duration,
• scene,
• characters,
• action,
• emotion,
• camera movement,
• narrative link to previous/next shot.

Default shot duration: 4-8s. Emotional high point may hold up to 10s.

Camera:

• opening wide/overhead miniature world establish,
• mid shots for interactions,
• closeups for props/faces,
• slow push/pull,
• gentle pan,
• restrained tracking.

Avoid fast cuts and aggressive handheld motion.

Prompt Rules

Image prompt should include:

miniature model photography, tilt-shift lens look, shallow depth of field, handmade miniature set, [characters/action/scene], delicate material texture, soft diffused lighting, warm muted palette, no full-size real-world scale confusion, no random text, no watermark

Video prompt should include:

Use the miniature character and scene references. [shot action and emotion]. Gentle [camera move], tilt-shift miniature depth of field, soft diffused light, delicate model texture, warm quiet pacing, no subtitles, no random text, no watermark, no music unless audio is intended in the clip.

Maintain scale logic:

• if prop is larger than a character, describe multiple characters cooperating.
• every action must name the actor.
• keep fixed scene props consistent.

Audio

BGM:

• gentle piano,
• light strings,
• warm instrumental,
• no vocals by default,
• fade in/out.

Narration optional:

• gentle,
• simple,
• matched to shot IDs,
• avoid overexplaining the emotion.

If video clips include built-in audio and separate narration exists, avoid overlapping unwanted speech/noise.

Quality Review

Check:

• true miniature/tilt-shift feel,
• story has an emotional arc,
• scale is consistent,
• actions have named actors,
• no impossible giant-object handling,
• no random text/watermark,
• references remain consistent,
• actual media URLs exist.

If it reads as full-size live action, regenerate with stronger miniature model and tilt-shift constraints.

Output Contract

Return:

• spec,
• story_beats,
• key_elements,
• shot_list,
• prompts,
• audio_plan,
• media,
• assembly_plan,
• review.

Do not present element images as finished video.
