MiMo Code

Summary
Interrupted or errored turns stay recoverable: the incomplete assistant message is kept as a candidate, and /recover continues the turn append-only without rewriting history.
Conversation titles can be generated through a dedicated API (POST /experimental/title, plus a genTitle helper) that falls back to a lite model when the preferred one is unavailable or returns invalid output.
TUI voice input is upgraded to a tool-based voice_input protocol: ASR applies caret/selection-aware insert or set, submit stays explicit through the send field, and the call shape is validated so models can drive it reliably.
Also in this release: compaction keeps a summary plus only the API rounds that arrive while that summary is generated, triggers at a flat 90% of the context window, and collapses the post-rebuild tail into an activity log; unused actor spawn/run resume arguments removed so models are pointed at send (already the supported path for waking and continuing a subagent); subagent actor use via exec limited to send; nested exec tool calls persisted and replayable in the TUI; same-session subagents inherit parent permission grants; per-session system prefix frozen in a snapshot for stable prompt-cache prefixes; optional auto_worktree notice (default off); skills updates for mate, pdf-official CJK fonts, and pptx-official image sourcing; plus provider/retry, MCP, compose-next, and build fixes.
---
中断或出错的回合仍可恢复：未完成的 assistant 消息会保留为候选，/recover 以 append-only 方式续跑，不改写历史。
会话标题可通过专用 API 生成（POST /experimental/title 与 genTitle helper）；首选模型不可用或返回无效结果时，会回退到 lite model。
TUI 语音输入升级为基于工具的 voice_input 协议：ASR 按光标/选区做 insert 或 set，发送始终由 send 字段显式触发；调用 schema 经过校验，模型可以稳定驱动。
本版本还包括：compaction 保留 summary 以及生成期间到达的 API 轮次，触发条件改为上下文窗口的固定 90%，重建后的 tail 收成活动日志；删除 actor spawn/run 中未实现的 resume 参数，把模型导向本来就能用的 send；子代理经 exec 使用 actor 时仅允许 send；嵌套 exec 调用会持久化且可在 TUI 回放；同会话子代理继承父级权限；会话 system prefix 冻结进快照以保持 prompt-cache 前缀稳定；可选的 auto_worktree 提示（默认关闭）；mate、pdf-official 中日文字体与 pptx-official 配图规则等 skill 更新；以及 provider/重试、MCP、compose-next 与构建相关修复。

Summary
The headline of this release is memory.disable_write — a switch that stops MiMoCode from writing memory while leaving reads intact. With it on, no checkpoints, MEMORY.md, notes.md or task progress.md are written and dream/distill stop running automatically; nothing is ever deleted and the builtin memory search tool keeps working. One caveat we corrected in the same release: existing memory is *not* auto-loaded while writing is off — the dumps normally reach context through a checkpoint rebuild, which is short-circuited by design when no new checkpoint can be written, so the switch's wording no longer promises automatic availability.
Also notable: a patched @ai-sdk/openai-compatible fixes MCP tools with more than two parameters silently losing their arguments — the stream parser finalized a tool call as soon as the accumulated arguments first parsed as valid JSON, so providers that emit complete-JSON snapshots (e.g. OpenRouter) had all later fragments dropped. Plus a new memory-search builtin skill (querying the SQLite trajectory DB) and an MCP refactor that makes the single-client-per-process property structural instead of relying on layer memoisation.
---
本次发布的主角是 memory.disable_write —— 一个只停写、不停读的记忆开关。开启后不再写入 checkpoint、MEMORY.md、notes.md 和任务 progress.md,dream/distill 也不再自动运行;任何文件都不会被删除,内置 memory 检索工具照常可用。同一版本里我们同时修正了一处措辞:停写期间既有记忆不会自动加载——记忆内容平时是靠 checkpoint 重建进入上下文的,而停写时无法写新 checkpoint,重建会按设计短路并降级为压缩,因此开关文案不再承诺"自动可用"。
另一个重点:通过给 @ai-sdk/openai-compatible 打补丁,修复了参数多于两个的 MCP 工具静默丢参数的问题——流解析器一旦发现累积的 arguments 首次能解析为合法 JSON 就提前完结该工具调用,导致以完整 JSON 快照方式推流的 provider(如 OpenRouter)后续片段全部被丢弃。此外还新增 memory-search 内置技能(查询 SQLite 轨迹库),以及一次 MCP 重构:把"每进程单一 client"从依赖 layer memo 的巧合变成图上可见的结构性保证。
