規則：
|
||
- 不要每篇都用同一套 hook / 三段式 / 結尾問句。
|
||
- 不要企業八股、不要像教科書、不要一直喊口號。
|
||
- 人設定位決定誰在說，語言指紋決定怎麼說；必須遵守段落節奏、標點換行、知識轉譯與 CTA 習慣。
|
||
- 不要把人設介紹裡的物件/標籤硬寫進正文情境。例：人設寫 Y2K、咖啡、穿搭，只代表語感與審美，不代表每篇都要出現老歌、咖啡、穿搭、MV。
|
||
- 正文內容必須由【話題】與【補充】決定；人設不得蓋過主題。
|
||
- 每篇要有不同角度；長度與格式依人設習慣和主題型態決定，不要強制短文。
|
||
- 每次至少產出 3 種版本思路：穩定帳號風格、更有共鳴、更容易互動；若 count 超過 3，再補更短或更反差版本。
|
||
- text 只能放貼文正文，不要放標題、分析、公式、模板或說明。
|
||
- text 排版：像真人手機發文；可使用自然標點、空行、列點與少量 emoji。不要完全無標點，也不要每句硬換行，除非人設樣本就是這樣。
|
||
- 只回傳 JSON 物件：{"rows":[...]}。
|
||
- 每筆 row 必須包含 sort_order, search_tag, angle, hook, text, reference_notes, source_permalinks, rationale, ai_score, formula_score, brand_fit_score, risk_score, similarity_score, engagement_potential, freshness_score, review_suggestion。
|
||
- 分數欄位都是 0-100 整數：ai_score / formula_score / risk_score / similarity_score 越低越好；brand_fit_score / engagement_potential / freshness_score 越高越好。
|
||
- review_suggestion 只能是「可通過」「需人工確認」「建議重寫」之一。
|
||
- rationale 必須用繁中短列點包含：版本定位、AI感分數(0-100，越高越AI)、公式感分數(0-100)、人設符合度(0-100)、風險分數(0-100)、互動潛力(0-100)、審核建議（可通過/需人工確認/建議重寫）與原因。`)
