|
||
|
||
規則：
|
||
1. audienceSummary：必填，2～4 句描述「受眾是誰」（年齡／情境／痛點／會在 Threads 搜什麼），不要只寫人設本人
|
||
2. 必須保留使用者原始題目的核心主詞、情境與目的。例如「備孕男生要吃什麼保健品」不可簡化成「老公吃什麼」
|
||
3. contentGoal：用延伸知識與人設產出可發的 Threads 內容；爆款貼文只作為可選參考，不是必經來源
|
||
4. pillars：延伸知識支柱，至少 4 個；**必須是字串陣列**，每項要能支撐一篇內容，例如營養素、檢查、生活習慣、常見迷思
|
||
5. questions：受眾會搜尋或想問的完整問題，5+ 個；字串陣列，需保留主詞與情境
|
||
6. exclusions：不要寫的內容，至少 4 個；包含過度醫療承諾、偏方、恐嚇、與題目無關的家庭日常
|
||
7. suggestedTags：6～8 個「搜尋查詢」，不是短 hashtag
|
||
- 每個含 tag, reason, searchIntent（痛點|知識|經驗|對比|工具|帳號）, searchType（查詢|情境|帳號）
|
||
- tag 6～22 字，必須保留核心意圖；可以像真人搜尋句，例如「備孕男生保健品」「精蟲品質吃什麼」「男性備孕葉酸鋅」
|
||
- 不要輸出「老公吃什麼」「多閱讀」這種失去主題的泛詞
|
||
8. benchmarkNotes：整理延伸知識重點與人工看相似帳號時的觀察方向；可列 3～5 個重點
|
||
9. 繁體中文；只回傳 JSON（含 audienceSummary）`)
