## 中文

Pi Agent Integrated 将 Pi 后端与 Pi Web 前端整合成一个可独立克隆、配置和启动的项目。它保留前后端源码边界，通过根目录命令完成依赖安装、Pi 构建、插件安装、Profile 初始化和 Web 启动。

### 与两个源项目有什么不同

| 能力 | Pi | Pi Web | Pi Agent Integrated |
| --- | --- | --- | --- |
| 主要定位 | CLI/TUI Agent 运行时 | Pi 的浏览器 UI | 带 Web UI 的完整本地 Agent 应用 |
| 安装方式 | 安装 CLI 或从源码构建 | 单独连接 Pi 包 | 根目录一次 `npm run setup` |
| 运行数据 | 默认使用用户主目录 | 跟随 Pi Profile | 会话、认证、记忆、插件、缓存全部进入项目 `data/` |
| 默认工作目录 | 当前终端目录 | 在用户主目录创建日期目录 | `data/workspaces/default/` |
| 扩展生态 | 支持 Skill、扩展和包 | 提供管理界面 | 固定版本插件、MCP、Skill、提示词和主题形成项目闭环 |
| 网络搜索 | 无项目专属搜索 | 无项目专属搜索 | 可选 SearXNG `web_search` 扩展 |
| 浏览器自动化 | 需自行接入 | 无默认浏览器 MCP | Playwright MCP，使用系统 Edge，按需启动 |
| 恢复与长期状态 | 会话树与基础状态 | 会话 UI | Rewind 检查点、项目内 Memory、自动重试 |
| 多代理 | 核心能力可扩展 | 展示工具调用 | 配置了自动判断复杂度的 `pi-subagents` 策略 |
| 本项目修复 | 不适用 | 上游行为 | 修复已结束会话状态 404、隐藏 Next.js 开发指示器、增加 Windows restart |

本仓库不是桌面安装包，也不是公网多用户服务。当前发布目标是：技术用户在 Windows 上克隆仓库、补充自己的模型凭据后，通过命令行启动一个隔离、可扩展的本地 Web Agent。

### 环境要求

- Windows 10/11（当前唯一实机验证平台）
- Node.js `22.19.0` 或更高版本
- npm 与 Git
- 首次安装时可访问 npm registry
- Microsoft Edge（仅 Playwright 浏览器工具需要；不会额外下载 Chromium）
- 至少一个由用户自行配置的模型供应商、订阅登录或兼容 API

### 快速开始

```powershell
git clone https://github.com/luckyyzh/pi-agent-new.git
cd pi-agent-new
npm run setup
npm run dev
```

打开 <http://127.0.0.1:30141>。

`npm run setup` 会：

1. 初始化项目内 `data/` Profile；
2. 安装并构建本地 Pi 源码；
3. 安装 Pi Web 并连接本地 Pi 包；
4. 安装、固定并加载检查默认插件；
5. 预缓存 Playwright MCP 包并确认系统 Edge 可用；
6. 检查前后端版本和构建产物。

安装脚本默认不继承 `HTTP_PROXY` / `HTTPS_PROXY`，避免失效代理阻塞 npm。如果安装必须使用代理，先设置 `$env:PI_SETUP_USE_PROXY = "1"`。

### 首次模型配置

仓库不会附带作者的模型地址、API Key、OAuth Token 或默认模型。应用可以在空模型配置下启动，但发送消息前必须完成以下任一方式：

- 在 Web UI 左下角进入“模型”，为内置供应商登录或填写 API Key；
- 在同一界面添加 Ollama、LM Studio、vLLM 或其他兼容 API；
- 编辑运行时文件 `data/agent/models.json`；
- 使用供应商支持的环境变量，例如 `ANTHROPIC_API_KEY`、`OPENAI_API_KEY` 或 `GEMINI_API_KEY`。

所有设备相关模型配置都位于被 Git 忽略的 `data/` 或 `.env` 中。

### 可选环境变量

需要可选服务时，复制模板：

```powershell
Copy-Item .env.example .env
```

根启动器会自动读取 `.env`，已有系统环境变量优先。常用变量如下：

| 变量 | 是否必需 | 用途 |
| --- | --- | --- |
| `SEARXNG_URL` | 使用 SearXNG 时必需 | 用户自己的 JSON 搜索代理端点 |
| `SEARXNG_TOKEN` | 使用 SearXNG 时必需 | 作为 `X-Search-Token` 请求头发送 |
| `CONTEXT7_API_KEY` | 可选 | 提高 Context7 文档查询限额 |
| 模型供应商 API Key | 按供应商 | 模型认证；也可通过 Web UI 配置 |
| `PI_AGENT_DATA_DIR` | 可选 | 将可变数据移动到其他目录 |

不要提交 `.env`、`data/`、真实密钥或包含密钥的截图。

### 项目结构和闭环边界

```text
pi/                         Pi 后端、Agent、CLI/TUI 源码
pi-web/                     Next.js Web 前端与 HTTP/SSE 服务
config/                     可提交的缺省设置、MCP 和子代理策略
resources/skills/           应用级 Skill
resources/extensions/       应用级 Pi 扩展
resources/prompts/          提示词模板
resources/themes/           主题
scripts/                    安装、启动、迁移与验证脚本
data/agent/                 会话、认证、模型、插件、记忆与工具状态
data/home/                  Pi 子进程主目录与 Rewind 检查点
data/cache/                 项目内 npm 缓存
data/workspaces/default/    默认工作目录
```

`data/` 不进入 Git。应随仓库分发的内容放在 `config/` 或 `resources/`；个人会话、记忆、凭据、插件安装结果和模型配置留在 `data/`。打开其他代码目录时，受管运行时不会自动加载其中的 `.pi` / `.agents` 资源，从而避免和其他 Agent 项目耦合。

### 内置插件与工具

所有版本固定在 `config/settings.default.json` 和 `config/mcp.default.json`。

| 插件/工具 | 功能 | 自动行为与用法 |
| --- | --- | --- |
| `pi-mcp-adapter@2.15.0` | 用一个紧凑代理工具接入 MCP | 模型使用 `mcp` 搜索并调用 MCP；`/mcp` 查看状态。外部宿主配置发现默认关闭 |
| `@playwright/mcp@0.0.78` | 真实网页导航、点击、表单、快照和截图 | 通过 MCP 按需启动，空闲 5 分钟退出；使用无痕 Headless 系统 Edge |
| `pi-lens@3.8.73` | LSP、AST、符号检索和项目诊断 | 模型按需激活代码智能工具；可用 `/lens-health`、`/lens-tools`、`/lens-map` 检查 |
| `pi-memory@0.4.0` | Markdown 长期记忆、日志、临时工作区和恢复记录 | 模型按需使用 memory 工具；文件位于 `data/agent/memory/`，默认不启用向量索引 |
| `pi-subagents@0.37.2` | 创建研究、规划或执行子代理 | 简单任务不委派，跨模块或可并行复杂任务自动判断；也可使用 `/run`、`/parallel` |
| `pi-smart-fetch@0.3.17` | 抓取单个或批量 URL 内容 | 模型按需使用 `web_fetch` / `batch_web_fetch`，也提供给研究子代理 |
| `@ayulab/pi-rewind@0.4.6` | 每轮前后创建代码检查点 | `/rewind` 恢复代码、会话或两者；`/checkpoint` 管理存储。自动恢复文件默认关闭 |
| `@upstash/context7-pi@0.1.2` | 查询当前库、框架、SDK 和 API 文档 | 模型先解析库 ID，再按需查询文档；无 Key 可使用公共限额 |
| `@narumitw/pi-retry@0.31.0` | 识别瞬时供应商错误和卡住的流 | 复用 Pi 内置重试；默认 180 秒无事件视为停滞，不增加正常请求的模型调用 |
| `resources/extensions/searxng-search.ts` | 用户自有 SearXNG 的 `web_search` | 配置 `SEARXNG_URL` 与 `SEARXNG_TOKEN` 后，模型对时效性或明确搜索请求自动调用 |

Playwright 不下载独立 Chromium。首次 `setup` 只缓存 MCP 的 Node.js 包；浏览器执行使用系统 Edge。

### Profile、迁移和自定义扩展

只创建缺失的项目 Profile 文件：

```powershell
npm run profile:init
```

显式复制已有 Pi Profile 和全局 Skill：

```powershell
npm run profile:migrate
npm run profile:migrate -- --dry-run
npm run profile:migrate -- --force
npm run profile:migrate -- --from D:\old-pi\agent --skills-from D:\old-skills
```

迁移只复制，不删除源数据，并清理指向仓库外部的绝对资源路径。后续共享扩展放入 `resources/extensions/` 并登记到其 `package.json`；共享 Skill、提示词和主题分别放入对应 `resources/` 目录。

### 常用命令

```powershell
npm run setup           # 完整安装、构建和 Profile 插件校验
npm run profile:packages # 安装缺失或版本不匹配的受管插件
npm run dev             # 127.0.0.1:30141 开发服务
npm run restart         # Windows：停止本项目旧开发进程并重新启动
npm run dev:lan         # 局域网监听；仅在可信网络使用
npm run build           # 构建 Pi Web 生产产物
npm run start           # 启动已构建的本机生产服务
npm run check           # 验证前后端整合结构
npm run check:profile   # 安装/加载并检查受管插件
npm run smoke:fresh-profile # 在临时目录验证全新 Profile 安装后自动清理
npm run typecheck       # Pi Web TypeScript 检查
npm run test:managed    # Profile、隔离、搜索契约等测试
npm run smoke           # 对运行中的 Web 服务做冒烟测试
npm run smoke:isolation # 验证外部 Skill/扩展不会泄漏进来
npm run smoke:search -- "关键词" # 使用真实 SearXNG；需要配置
```

除 `smoke:search` 会访问用户配置的 SearXNG 外，以上验证不会发起付费模型请求。

### 上游、更新和许可证

- Pi 基线：`0.83.0`，提交 `bb226f9c1f38d3c029156a690e97bbfc602336b9`
- Pi Web 基线：`0.8.4`，提交 `c9b47e4543b11ce61e5c49c6bf02cea80aa975f6`

本整合版不自动跟随上游。更新时应分别评估两个源码树，重新执行 `npm run setup`、类型检查和受管测试，再更新这里的基线信息。根目录整合代码采用 MIT；两个源码树和运行时插件保留各自许可证，详见 [THIRD_PARTY_NOTICES.md](THIRD_PARTY_NOTICES.md)。安全边界见 [SECURITY.md](SECURITY.md)，贡献约定见 [CONTRIBUTING.md](CONTRIBUTING.md)。

## English

Pi Agent Integrated combines the Pi backend and Pi Web frontend into one independently cloneable and runnable repository. It preserves separate source boundaries while root commands handle dependency installation, Pi builds, managed-profile creation, plugin installation, and Web startup.

### How it differs from the two upstream projects

| Capability | Pi | Pi Web | Pi Agent Integrated |
| --- | --- | --- | --- |
| Primary role | CLI/TUI agent runtime | Browser UI for Pi | Complete local agent application with Web UI |
| Installation | Install CLI or build source | Connect Pi packages separately | One root `npm run setup` |
| Mutable state | User home by default | Follows the Pi profile | Sessions, auth, memory, plugins, and caches stay under repository `data/` |
| Default workspace | Current terminal directory | Creates a dated home directory | `data/workspaces/default/` |
| Extension ecosystem | Supports skills, extensions, packages | Management UI | Pinned plugins, MCP, skills, prompts, and themes form a managed ecosystem |
| Web search | No project-specific search | No project-specific search | Optional SearXNG `web_search` extension |
| Browser automation | User-integrated | No default browser MCP | Lazy Playwright MCP using system Edge |
| Recovery and durable context | Session tree and core state | Session UI | Rewind checkpoints, repository-local memory, automatic retry |
| Multi-agent workflow | Extensible core | Renders tool calls | Automatic complexity policy for `pi-subagents` |
| Integration fixes | Not applicable | Upstream behavior | Handles ended-session state 404s, hides Next dev indicators, adds Windows restart |

This repository is not a desktop installer or a public multi-user service. Its current release target is a technical Windows user who clones the project, supplies personal model credentials, and starts an isolated, extensible local Web agent from the command line.

### Requirements

- Windows 10/11, the only currently validated platform
- Node.js `22.19.0` or newer
- npm and Git
- npm registry access during initial setup
- Microsoft Edge for Playwright browser tools; no separate Chromium is downloaded
- At least one user-configured model provider, subscription login, or compatible API

### Quick start

```powershell
git clone https://github.com/luckyyzh/pi-agent-new.git
cd pi-agent-new
npm run setup
npm run dev
```

Open <http://127.0.0.1:30141>.

Setup initializes the repository-local profile, builds Pi, links Pi Web to the local packages, installs and loads the pinned plugins, caches the Playwright MCP Node package without downloading a browser, verifies system Edge, and checks integration artifacts.

Child npm operations ignore `HTTP_PROXY` and `HTTPS_PROXY` by default to avoid stale proxy configuration. Set `$env:PI_SETUP_USE_PROXY = "1"` first when registry access requires the proxy.

### First model configuration

The repository contains no author model endpoint, API key, OAuth token, or default model. The UI starts with an empty model configuration, but one of the following is required before sending a message:

- open Models in the lower-left Web UI and authenticate or enter an API key for a built-in provider;
- add Ollama, LM Studio, vLLM, or another compatible API in the same UI;
- edit the runtime file `data/agent/models.json`;
- set a supported variable such as `ANTHROPIC_API_KEY`, `OPENAI_API_KEY`, or `GEMINI_API_KEY`.

Device-specific model configuration remains in ignored `data/` or `.env` files.

### Optional environment configuration

```powershell
Copy-Item .env.example .env
```

The managed launcher automatically reads `.env`, while existing process variables take precedence.

| Variable | Required | Purpose |
| --- | --- | --- |
| `SEARXNG_URL` | When using SearXNG | The user's JSON search proxy endpoint |
| `SEARXNG_TOKEN` | When using SearXNG | Sent as the `X-Search-Token` request header |
| `CONTEXT7_API_KEY` | Optional | Higher Context7 documentation quota |
| Provider API keys | Provider-specific | Model authentication; the Web UI is another option |
| `PI_AGENT_DATA_DIR` | Optional | Relocate mutable runtime data |

Never commit `.env`, `data/`, real credentials, or screenshots containing credentials.

### Repository-local ecosystem

```text
pi/                         Pi backend, agent, and CLI/TUI source
pi-web/                     Next.js frontend and HTTP/SSE service
config/                     Versioned settings, MCP, and subagent policy
resources/skills/           Application skills
resources/extensions/       Application Pi extensions
resources/prompts/          Prompt templates
resources/themes/           Themes
scripts/                    Setup, launch, migration, and verification
data/agent/                 Sessions, auth, models, packages, memory, tools
data/home/                  Pi subprocess home and Rewind checkpoints
data/cache/                 Repository-local npm cache
data/workspaces/default/    Default workspace
```

`data/` is excluded from Git. Shareable defaults belong in `config/` or `resources/`; personal sessions, memory, credentials, installed packages, and model settings remain in `data/`. The managed runtime does not automatically load `.pi` or `.agents` resources from another opened workspace.

### Included plugins and tools

Versions are pinned in `config/settings.default.json` and `config/mcp.default.json`.

| Plugin/tool | Function | Automatic behavior and usage |
| --- | --- | --- |
| `pi-mcp-adapter@2.15.0` | Compact MCP proxy | The model searches and invokes MCP through `mcp`; `/mcp` shows status. Host-config discovery is off |
| `@playwright/mcp@0.0.78` | Real navigation, clicks, forms, snapshots, screenshots | Starts on demand, exits after five idle minutes, uses isolated headless system Edge |
| `pi-lens@3.8.73` | LSP, AST, symbols, project diagnostics | The model activates code intelligence on demand; inspect with `/lens-health`, `/lens-tools`, `/lens-map` |
| `pi-memory@0.4.0` | Markdown durable facts, logs, scratchpad, recovery | The model uses memory tools on demand; files live under `data/agent/memory/`; vector indexing is off by default |
| `pi-subagents@0.37.2` | Research, planning, execution subagents | Simple tasks stay local; complex or parallel work may delegate automatically; `/run` and `/parallel` remain available |
| `pi-smart-fetch@0.3.17` | Single and batched URL retrieval | Provides `web_fetch` and `batch_web_fetch` to the main and research agents |
| `@ayulab/pi-rewind@0.4.6` | Per-turn code checkpoints | `/rewind` restores code, conversation, or both; `/checkpoint` manages storage. Automatic file restore is off |
| `@upstash/context7-pi@0.1.2` | Current library, framework, SDK, API docs | Resolves a library ID and queries docs when needed; public quota works without a key |
| `@narumitw/pi-retry@0.31.0` | Transient provider and stalled-stream classification | Uses Pi's built-in retry path; 180 seconds without events is a stall; no extra normal model calls |
| `resources/extensions/searxng-search.ts` | `web_search` against a user-owned SearXNG proxy | After `SEARXNG_URL` and `SEARXNG_TOKEN` are set, the model calls it for current or explicit search requests |

Playwright never downloads a standalone Chromium in this project. Setup caches only its Node package; browser execution uses system Edge.

### Profile, migration, and extension

```powershell
npm run profile:init
npm run profile:migrate
npm run profile:migrate -- --dry-run
npm run profile:migrate -- --force
npm run profile:migrate -- --from D:\old-pi\agent --skills-from D:\old-skills
```

Migration copies without deleting source data and removes absolute resource paths pointing outside the repository. Put future shared extensions in `resources/extensions/` and register them in its `package.json`; use the corresponding `resources/` directories for shared skills, prompts, and themes.

### Commands

```powershell
npm run setup           # Full install, build, and managed-profile validation
npm run profile:packages # Install missing or version-mismatched managed plugins
npm run dev             # Development server on 127.0.0.1:30141
npm run restart         # Windows: stop this project's old dev process and restart
npm run dev:lan         # Listen on the LAN; trusted networks only
npm run build           # Build the Pi Web production output
npm run start           # Start an existing local production build
npm run check           # Verify backend/frontend integration
npm run check:profile   # Install/load and verify managed plugins
npm run smoke:fresh-profile # Verify a clean temporary profile, then remove it
npm run typecheck       # Pi Web TypeScript check
npm run test:managed    # Profile, isolation, and search-contract tests
npm run smoke           # Smoke-test a running Web service
npm run smoke:isolation # Verify external skills/extensions remain isolated
npm run smoke:search -- "query" # Real configured SearXNG request
```

Except for `smoke:search`, validation does not make paid model requests.
