256 KiB 预览限制。 +- 原预算算法会逐条移除全部来源消息，长中文项目分析可只留下当前含糊追问。现在保留最近问题/回答的首尾节选；同时节选过长的上一轮老师回复，避免预留读取预算后连续追问失败。节选包含消息 ID，并可通过工具恢复中间原文；当前问题、明确引用和系统指令仍保留，超预算明确报错。 +- 原生 SSE 支持分片工具调用参数、只读结果回传和继续生成；每轮最多六批读取后要求最终文本，计算工具定义/结果/原生思考的输入预算，成组省略较早工具轮次并累计模型用量。思考内容仅用于 Main 内原生后续请求，不发给 Renderer、不持久化。每次读取和后续模型调用检查账号与取消状态。 +- UI 标明结合当前会话和项目文件答疑，显示上下文节选提示；既有话题无需迁移或重新创建，运营试聊仍不获得真实项目工具。README 已同步当前行为。 +- 本次只修改客户端，未修改云端协议、运营配置或数据库；不合并、不推送、不部署，不清理任务工作目录。 + +## Verification + +- Red-capable loop：实际 CodingTeacherService

impact：后续预算调整必须覆盖连续追问和工具结果开销。Semantic conflict：无；无需额外人类确认。 diff --git a/README.md b/README.md index dc1d303e..46903785 100644 --- a/README.md +++ b/README.md @@ -156,7 +156,8 @@ Pi 正式包必须继续运行 `pnpm run
