Summary
This release ships a builtin skills system — 14 domain-specific skill bundles (document handling, academic writing, arXiv search, deep research, super-research, html-to-video, skill authoring, design blueprint, and self-documentation) that auto-load when relevant files are attached or task context matches. Skills show localized descriptions in the TUI dialog and support auto-detection of office file attachments. The self-extend skill is renamed to evolve, reframing it as a proactive total self-modification interface. Two new built-in research workflows ship alongside: deep-research (parallel sub-agents → reflect → cited report) and fact-check (adversarial 3-juror verification).
Other highlights: Windows native installer now fully supported (PowerShell one-liner, working upgrade/uninstall); vision-aware image paste spills images to temp files for non-vision models with automatic multimodal model selection; Edit tool defaults to exact string matching (fuzzy now opt-in); gpt-5.5 encrypted reasoning round-trip fix; rewritten repetition detector eliminating false-positive loop-kills on structured content.
Experimental opt-in: Orchestrator mode (MIMOCODE_EXPERIMENTAL_ORCHESTRATOR) adds delegating multi-session coordination with git worktree isolation; cron + loop scheduling (MIMOCODE_EXPERIMENTAL_CRON) enables recurring prompts with durable persistence.
这个版本的重点是内置 Skills——14 个领域 skill 随版本分发（办公文档、学术写作、arXiv 检索、深度调研、超级科研、HTML 转视频、skill 创作、设计蓝图、自文档化等），挂载相关文件或上下文命中时自动激活，TUI 对话框显示多语言描述。self-extend 改名 evolve，作为全面自我修改的入口。同时上线 deep-research 和 fact-check 两个内置 workflow。
其他值得关注的：Windows 一行式安装命令正式可用（upgrade/uninstall 完整支持）；粘贴图片时非多模态模型会收到临时文件引用而非 base64，自动选用多模态模型处理；Edit 工具默认精确匹配；gpt-5.5 加密 reasoning 往返修复；重复检测器重写，不再误杀结构化内容。
实验性功能（需手动开启）：Orchestrator 模式支持委派式多 session 协作；cron + loop 支持定时与自适应循环。

self-extendtoevolve— rewrite SKILL.md as proactive total self-modification interface (tools, hooks, knowledge, workflows, UI all rewritable); sync hook-api.md with missing events; addctx.ask()to tool-api.md (#1590) - installer: first-class Windows PowerShell native installer (one-liner alongside macOS/Linux), working
mimo upgrade/mimo uninstall, UTF-8 encoding; recommend native installer for npm/pnpm/bun users (#1511, #1549, #1551, #1592) - tui: vision-aware image paste — non-vision models receive a temp-file
@filereference instead of base64 bytes; automatic multimodal model selection;actor models [--vision]discovery command (#1513, #1546) - edit: default to exact string matching with closest-match error hints — fuzzy matching moved to opt-in via
MIMOCODE_ENABLE_FUZZY_EDIT(#1466) - security: secondary permission prompt for irreversible bash deletions (
bash_deletepermission type) — interceptsrm,rmdir,shred,git reset --hard,git push --force, etc. Opt-out viaMIMOCODE_AUTO_APPROVE_DELETE=true(#1588) - tui:

- config: automatic
$schemaURL migration fromopencode.aitomimo.xiaomi.com/mimocode/(#1511) - bash: token efficiency pipeline (opt-in,
MIMOCODE_EXPERIMENTAL_TOKEN_EFFICIENCY_HEURISTIC) — heuristic shape-based filter strips predictable noise from common output patterns (#1473, #1519) - provider: non-empty
provider.<id>.modelsconfig acts as implicit whitelist whenonly_configured_modelsis enabled (#1532, #1589) - orchestrator: Orchestrator mode (opt-in,
MIMOCODE_EXPERIMENTAL_ORCHESTRATOR) — a primary agent that delegates to child sessions via asessiontool with create/switch/list/cancel/ask/approve verbs, git worktree isolation per child, permission-approval forwarding (#1529) - cron: cron + loop scheduling system (opt-in,

Bug Fixes
- provider: fix gpt-5.5 empty output and
reasoning part rs_… not founderrors — request encrypted reasoning content for Responses API round-tripping (#1530) - provider: defer vision model resolution to
environment()call time — fixes crash wheremimo upgrade/mimo uninstallfailed without project context (#1546) - detection: rewrite repetition detector from sliding-window n-gram to consecutive-block repeat algorithm — eliminates false-positive loop-kills on structured content; adds CJK character-level tokenization (#1476)
- tui: patch @opentui/core@0.1.101 to fix CJK paste-highlight drift (UTF-16 length → display width) (#1471)
- tui: prevent double session creation on home screen submit (#1497)
- tui: clear alternate screen buffer before spawning interactive commands (#1492)
- tui: fix background actor Task showing "completed · 0ms" while still running (#1499)
- session: add HTTP 400 to retryable status codes; exclude system sessions from
mimo -c(#1528) - effect: two-phase instance disposal — Bus shuts down after other services emit final events, fixing sessions stuck as permanently busy (#1527)
- build: generate
ext/_manifest.tsin Node target (#1501) - compose: strengthen skill invocation prompt and fix RLHF resistance (#1598)
Refactor
- Prediction uses side-channel
generateTextinstead ofllm.stream— bypasses session-coupled hooks, uses tighter context window (#1498)
Docs
- Add Builtin Skills and Workflows sections to README (en/zh) (#1581)
