学校の怪談
放課後の学校で、数が合わない。 学校の怪談は、怪物ではなく「計算違い」の話です。このスキルは、日本の学校に伝わる怪談の文法で短編ホラーを作ります。 ・モチーフを1つ選びます — ひとりでに鳴るピアノ、増える階段、トイレの怪異、理科室の人体模型、鏡、下駄箱、卒業アルバム、校内放送 ・「合わない数」を先に決めます — 生徒が一人多い、上履きが一足多い、階段が一段多い、放送に一人分多い声 ・8拍構成 — 校内放送、放課後の教室、ひとりでに鳴るピアノ、二人分の足音、異変に気づく、数が合わない、名前を呼ぶ放送、チャイムで終わる ・校内の音 — ウェストミンスターのチャイム、割れたスピーカー、下駄箱のきしみ、上履きの音、ピアノの単音、そして突然の完全な無音 ・参考映像の解析 — 日本のホラー映像をアップロードするか YouTube / TikTok / Instagram のリンクを貼ると、時間帯の光、カットの長さ、異変の位置、学校の環境音を読み取り、同じ空気感のオリジナル映像を作ります このジャンルの鉄則は「幽霊を見せないこと」。怖さは数が合わないことにあります。顔のアップも、脅かし音も、説明字幕もありません。 画面内の文字はすべて日本語です。実在の学校名・校章・人物は使用しません。グロ表現は扱いません。オリジナル制作のみで、参考映像の流用はしません。

Do **not** use this skill for: gore or slasher content, pranks that target a real person, naming a real school, real students, or reproducing a specific film's scenes — see Notes. ## Steps ### 0. Clarify — the count comes first Call `write_todos` with the plan: clarify → (optional) reference analysis → pick the motif → storyboard → stills → shots → sound → edit. A school ghost story is not a monster attack. It is **an arithmetic error in an ordinary school day** — so decide *what does not add up* before generating anything. Then ask, in one short message, only what you still need: 1. **Which school space?** (教室 / 音楽室 / 理科室 / トイレ / 体育館 / 下駄箱 / 渡り廊下) 2. **What is the wrong count?** (one extra student, one extra pair of 上履き, one more step than the staircase has, one more voice in the 校内放送) 3. **Length** — 15s teaser / 30s short / 60s episode. 4. **Frame** — portrait 9:16 for Shorts, or landscape 16:9 for a "recorded" feel. State the motif and the wrong count back in one line (Japanese) and get a yes. **If the count is not decided, the story does not work.** ### 1. Reference analysis (only if the user supplies a clip) For a YouTube / TikTok / Instagram link, resolve it first with `download_video(url=...)` and pass the returned `downloadUrl` to `recognize_video`. For an uploaded file, pass the asset URL. ``` recognize_video(video_url=<url>, prompt='Analyse this as a Japanese school horror scene. Report: the time of day and light sources, average shot length, how static the camera is, where in the frame the anomaly appears, how long the anomaly is held before the cut, what school sounds are present (chime, PA, footsteps, piano, water), and how the scene ends. Do not describe the plot.') ``` Turn the answer into a short **treatment note** and read it back to the user. Then build an **original** scene. ### 2. Pick the motif — exactly one, from the Japanese canon | Motif | What the audience already knows | |---|---| | **ひとりでに鳴るピアノ** | 音楽室, a piano playing with nobody at it | | **増える階段** | 13 段のはずの階段が 14 段ある | | **トイレの怪異** | 個室のドア, a voice from the next stall | | **理科室の人体模型** | it has moved slightly between shots | | **鏡** | 洗面所の鏡, a reflection that lags | | **下駄箱** | one extra pair of 上履き, a nametag nobody recognises | | **卒業アルバム / クラス写真** | one more person than the class roll | | **校内放送** | the PA calls a name that is not on the list | Say which one you are using and why, in one sentence (Japanese). ### 3. Storyboard — 8 beats, about 30 seconds Show this to the user before generating. Shots are the expensive part. | # | Beat | Length | What happens | |---|---|---|---| | 1 | 校内放送が入る | 3s | The PA crackles, the チャイム rings, then nothing | | 2 | 放課後の教室 | 6s | Empty desks, low sun through the windows, dust in the air | | 3 | 音楽室 — ピアノがひとりでに鳴る | 6s | The keys move; nobody is in the room. Hold this beat | | 4 | 廊下 — 足音が二人分 | 5s | One person walking, two sets of footsteps | | 5 | 異変に気づく | 4s | The character notices the count is wrong. **Do not show what they see** | | 6 | 数が合わない | 3s | T
