What it does它能做什么

The interface PI is missing — nothing more. PI 缺的那层界面，仅此而已。

Multi-session workbench多会话工作台

Projects → sessions, up to four pooled runtimes, streaming output, tool cards with expandable arguments and results, pasted screenshots, steer and abort mid-run.项目 → 会话，最多 4 个 runtime 池化复用，流式输出、工具卡（参数与结果可展开）、截图直接粘贴、运行中 steer / abort。

Community extensions, rendered natively社区扩展原生适配

Todo panel, plan-mode cards and goal commands get purpose-built UI. Anything unrecognized falls back to a generic tool card — no blank screens, no dropped events.todo 面板、plan 卡片、goal 命令都有专属 UI；未识别的工具走通用卡片，不白屏、不丢事件。

Extension UI扩展 UI 响应

Select, confirm, input and notify prompts from extensions appear as native cards — click to answer.扩展弹出的 select / confirm / input / notify 以原生卡片呈现，直接点选即可。

Slash commandsSlash 命令补全

Type / to browse commands, prompt templates and skills from your own PI setup, with the source labeled.输入 / 列出你已安装的扩展命令、prompt 模板和 skill，来源一目了然。

Models & thinking模型与思考等级

Read straight from your PI model catalog; switch model or thinking level mid-session.直接读 PI 的模型目录，会话内随时切换模型与思考等级。

Git contextGit 上下文

See branches and worktrees, create a worktree in one click, open the project in Finder, Ghostty or VS Code.查看分支与 worktree、一键创建、在 Finder / Ghostty / VS Code 中打开项目。

Task board任务看板optional

Create a card, dispatch it to an agent, review the result. State lives in the project's own event log, and nothing is written until you use it.建卡 → 派发给 Agent → 审核结果。状态写在项目自己的事件日志里，不用就不写入任何文件。

Remote runtimeRemote runtimebeta

Install pion-daemon on another machine and use its projects as if they were local.在另一台机器上装 pion-daemon，把它的项目接进来，像本地项目一样用。

Your PI, unchanged你的 PI，原样不动

Pion is a window, not a fork. Pion 是一个窗口，不是一份分支。

Native PI原生 PI

Everything goes through pi --mode rpc. No TUI scraping, no reimplemented agent runtime.全部走 pi --mode rpc，不解析 TUI 屏幕，不重写 Agent Runtime。

No bundled opinions零私货

No author prompts, skills or extensions ship with the app. Your environment is what you see.不自带作者的 prompt、skill 或 extension。你装了什么，界面就显示什么。

Your history stays PI's历史就是 PI 的历史

PI session JSONL is the only source of truth. No second transcript database, nothing to migrate away from.PI session JSONL 是唯一真相来源，不建第二份 transcript 库，随时可以卸载。
