拆解 GBrain query skill:YC 總裁自己用的 brain,回答問題的 5 條規矩

from 脈報 · host 思思主播

拆解 GBrain query skill 的 5 條規矩:grounded only、source precedence、gap flag、chunk-first、graph 走結構。看 YC 總裁 Garry Tan 怎麼把 query 寫成可機械驗收的契約,而不是又一個 RAG prompt 模板。 ⭐ 文章深度讀:把 5 條規矩搬到自己的 agent skill 系統 → https://heymaibao.com/gbrain-query-skill-deconstruction/ 📝 懶人包 ∙ query skill 是契約不是 prompt template , 不可退讓判斷、anti-patterns、輸出格式、工具索引全部寫死,LLM 讀完照做。 ∙ 5 條規矩:grounded only、source precedence、gap flag、chunk-first、graph 走結構。 ∙ Graph 層 + extract 品質讓 GBrain 在 BrainBench 拿 P@5 49.1% 、 R@5 97.9%,比 graph-disabled 高 31.4 點 P@5。 ∙ 可帶走的 builder 原則:skill 是契約不是 prompt、anti-patterns 比正向 do 更能定義邊界、retrieval 分職責不互相吃。
