Anthropic 删减 Claude Code 系统提示词 80%，新模型无需严格规则仍保持编码性能

ChainThink 消息，7 月 25 日，据 Anthropic 工程师披露，团队为最新 Claude 模型删减了 Claude Code 约 80% 的系统提示词，编码评估未出现性能下降。

早期版本因模型能力不足，提示词中包含大量严格规则，例如禁止多行注释等；在新模型具备更强自主决策能力后，这类规则反而可能引发指令冲突和思维发散。

Anthropic 目前改为描述目标，例如“编写与周围代码匹配的代码”，并将指令分散至工具描述和按需启用的技能模块中。

团队将提示词膨胀视为技术债务，认为模型能力提升后应简化而非继续堆叠指令。
