XiaomiMiMo/MiMo-Code v0.1.14

on GitHub

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。

• session: freeze the per-session system prefix in a persistent snapshot; move skill catalogs from user messages to the system tail; preserve prompt cache prefixes by @MiMoHardFather in #2289, #2287, #2258
• sdk: expose reliable POST /experimental/title / genTitle with lite-model fallback and write guards by @wqymi in #2228
• actor: drop unimplemented spawn/run actor_id resume arguments; keep send as the path for waking and continuing a subagent by @yanyihan-xiaomi in #2262
• actor: limit subagent actor calls through exec to send only by @wqymi in #2217, #2223
• exec: persist replayable nested tool parts (versioned snapshots, TUI renderers, debounce) by @yanyihan-xiaomi in #2222
• permission: same-session subagents inherit parent grants (fall back to current session id for inherit parent) by @wqymi in #2273
• config: add auto_worktree toggle (default off); path-based once-per-session main-worktree mutation notice by @wqymi in #2227, #2270, #2292
• skill: add mate builtin skill for desktop pet creation by @oscar-cao7 in #2225
• skill: pdf-official CJK font protocol (per-OS TTF ladder, CID STSong-Light fallback, never Helvetica) by @oscar-cao7 in #2189
• skill: pptx-official image sourcing decision rules (draw / cite / search / generate; limited image_gen budget) by @oscar-cao7 in #2265
• provider: route Xiaomi PTC through Responses custom exec; keep exec gateway available under GPT tool filtering by @MiMoHardFather in #2203, #2183
• tool-script: typed exec_command parameters (cmd, yield_time_ms, workdir); resolve MCP-prefixed tool aliases by @MiMoHardFather in #2180, #2202

Bug Fixes

• provider: use 128K output defaults for large model families; align large-model output and compaction reserves by @MiMoHardFather in #2181, #2182
• provider: stabilize defaultModel fallback (cfg → recent → id-asc first allowed; no menu-priority sort) by @wqymi in #2306
• session: centralize provider retry coordination (terminal vs transient, Retry-After, no live-step replay after side effects) by @wqymi in #2216
• session: scope replace-agent base override to main/peer actors so subagents keep their own agent prompt by @MiMoHardFather in #2264
• session: allow relative paths within the workspace for file/search tools by @yanyihan-xiaomi in #2251
• session: defer text part creation until first delta (no empty text shells in DB) by @wqymi in #2193
• skill: replace broken skill-tools filtering with glob prefix matching; remove skill-search reminder infrastructure by @MiMoHardFather in #2166, #2168
• llm-server: advertise Server.listen so mimo llm-server issue resolves a real base_url; publish/unpublish on serve stop by @wqymi in #2293
• mcp: record local startup exit code and stderr tail on stdio failure by @wqymi in #2269
• mcp: show MiMoCode branding in OAuth callback pages and DCR client registration by @MiMoHardFather in #2301
• compose-next: require spec to land in the worktree (pipeline grill → workspace → spec → implement) by @yanyihan-xiaomi in #2307
• actor: scope fork contexts by session so repeated actor ids cannot collide across sessions by @wqymi in #2259
• build: prevent ancestor node_modules bun from hijacking compiled binaries (pin check + process.execPath) by @MiMoHardFather in #2291
• build-node: define MIMOCODE_VERSION for the node target so embedded builds stop extracting under builtin_skills/local/ by @yanyihan-xiaomi in #2297

Refactor

• skill: move drive-mimo to repository scope (.mimocode/skills/) instead of the product-wide builtin bundle by @yanyihan-xiaomi in #2210
• session: simplify harness selection — explicit harness flag is the single source of truth; PTC transport no longer auto-selects the GPT toolset; MIMOCODE_CODEX_MODE=false forces the default harness for every model by @MiMoHardFather in #2243, #2252, #2303
• tool: remove standalone change_directory; require absolute working directories for shell/code-mode commands by @yanyihan-xiaomi in #2239
• prompt: rewrite Tools section as “Using your tools” guidance; instruction files default-on and decoupled from the dynamic system prompt flag by @MiMoHardFather in #2302, #2285

Internal / CI

• session: retune the auto-overflow fixture for the flat 90% trigger by @yanyihan-xiaomi in #2266

• chore: bump version to 0.1.14 by @yanyihan-xiaomi in #2311
