AGENTS.md 到底有沒有用?研究出爐:寫太多反而讓結果更糟

from 脈報 · host 思思主播

研究發現自動生成的 AGENTS.md 反而降低 coding agent 成功率且增加 20% 成本。人寫版也只提升 4%。Agent 不是不聽話,是聽太多話。整理研究數據並告訴你該怎麼改寫。 ⭐ 文章深度讀:文章最後整理了該寫、該刪的具體清單 → https://heymaibao.com/agents-md-evaluation-research/ 📝 懶人包 ∙ LLM 自動生成的 AGENTS.md / CLAUDE.md (例如用 /init 指令) 反而降低 coding agent 的成功率,同時推理成本增加超過 20%。 ∙ 開發者手寫的 context file 效果也有限,平均只提升 4% 成功率,而且 agent 會忠實遵守裡面的每條指令。 ∙ 問題出在「過度規格化」:agent 花太多時間遵守不必要的指令,反而沒時間解決實際問題。 ∙ 這篇研究測的是「解 GitHub issue」的封閉任務,日常開發情境不同。但核心啟示一致:context file 只寫最低必要,別貪多。 📚 參考資料 Gloaguen et al., 2026.
