 ## Project Overview
 
-This is a **monorepo** with npm workspaces containing **two main packages**:
+This is a **monorepo** with npm workspaces:
 
-1. **Core Library** (`packages/page-agent/`) - Pure JavaScript/TypeScript AI agent library for browser DOM automation, published as `page-agent` on npm
+- **Core Library** (`packages/page-agent/`) - AI agent for browser DOM automation, published as `page-agent` on npm
-2. **Website** (`packages/website/`) - React documentation and landing page. Also as demo and test page for the core lib. private package `@page-agent/website`
+- **Website** (`packages/website/`) - React docs and landing page. **When working on website, follow `packages/website/AGENTS.md`**
+
+Internal packages:
+
+- **LLMs** (`packages/llms/`) - LLM client with reflection-before-action mental model
+- **Page Controller** (`packages/page-controller/`) - DOM operations, independent of LLM
+- **UI** (`packages/ui/`) - Panel, SimulatorMask, i18n. Decoupled from PageAgent
 
 ## Development Commands
 
-### Core Commands
-
 ```bash
 npm start                    # Start website dev server
-npm run dev                  # Same as start
 npm run build                # Build all packages
-npm run build:lib            # Build page-agent library only
+npm run build:libs           # Build all libraries
 npm run lint                 # ESLint with TypeScript strict rules
 ```
 
-### Package-specific Commands
+## Architecture
-
-```bash
-# Core library
-npm run build --workspace=page-agent
-npm run build:watch --workspace=page-agent
-
-# Website
-npm run dev --workspace=@page-agent/website
-npm run build --workspace=@page-agent/website
-```
-
-## Architecture & Critical Patterns
 
 ### Monorepo Structure
 
+Simple monorepo solution: TypeScript references + Vite aliases. Update tsconfig and vite config when adding/removing packages.
+
 ```
 packages/
-├── page-agent/              # npm: "page-agent"
+├── page-agent/              # npm: "page-agent" ⭐ MAIN
-│   ├── src/                 # Core library source
+├── website/                 # @page-agent/website (private)
-│   ├── vite.config.js       # Library build (ES + UMD)
+├── llms/                    # @page-agent/llms
-│   └── package.json
+├── page-controller/         # @page-agent/page-controller
-└── website/                 # npm: "@page-agent/website" (private)
+└── ui/                      # @page-agent/ui
-    ├── src/                 # Website source (formerly pages/)
-    ├── index.html
-    ├── vite.config.js       # Website build
-    └── package.json
 ```
 
-### Module Boundaries (Critical)
+`workspaces` in `package.json` must be in topological order.
 
-- **Core library** (`packages/page-agent/`): NEVER import from website - must remain pure JavaScript
+### Module Boundaries
-- **Website** (`packages/website/`): CAN import from `page-agent` for demos. Alias `@/` → `website/src/`
+
+- **Page Agent**: Core lib. Imports from `@page-agent/llms`, `@page-agent/page-controller`, `@page-agent/ui`
+- **LLMs**: LLM client with MacroToolInput contract. No dependency on page-agent
+- **UI**: Panel, Mask, i18n. No dependency on page-agent
+- **Page Controller**: Pure DOM operations. No LLM or UI dependency
+
+### PageController ↔ PageAgent Communication
+
+All communication is async and isolated:
+
+```typescript
+// PageAgent delegates DOM operations to PageController
+await this.pageController.updateTree()
+await this.pageController.clickElement(index)
+await this.pageController.inputText(index, text)
+await this.pageController.scroll({ down: true, numPages: 1 })
+
+// PageController exposes state via async methods
+const simplifiedHTML = await this.pageController.getSimplifiedHTML()
+const pageInfo = await this.pageController.getPageInfo()
+```
 
 ### DOM Pipeline
 
-1. **DOM Extraction**: Convert live DOM to `FlatDomTree` via `src/dom/dom_tree/`
+1. **DOM Extraction**: Live DOM → `FlatDomTree` via `page-controller/src/dom/dom_tree/`
-2. **Dehydration**: DOM tree → simplified text for LLM processing
+2. **Dehydration**: DOM tree → simplified text for LLM
-3. **LLM Processing**: AI model returns action plans
+3. **LLM Processing**: AI returns action plans (page-agent)
-4. **Indexed Operations**: Map LLM responses back to specific DOM elements
+4. **Indexed Operations**: PageAgent calls PageController by element index
 
-### Event Bus Communication
+### CDN Auto-Injection
 
-Use `src/utils/bus.ts` for decoupled PageAgent ↔ UI communication:
+Library auto-initializes via script tag:
-
-```typescript
-// Emit from PageAgent
-getEventBus().emit('panel:show')
-getEventBus().emit('panel:update', { status: 'thinking' })
-
-// Listen in UI components
-getEventBus().on('panel:show', () => panel.show())
-```
-
-### Hash Routing Requirement
-
-Uses wouter with `useHashLocation` for static hosting:
-
-```tsx
-<Router hook={useHashLocation}>  // Always hash-based routes
-```
-
-### CDN Auto-Injection Pattern
-
-Library auto-initializes when injected via script tag:
 
 ```html
 <script src="page-agent.js?model=gpt-4"></script>
 ```
 
-Query params configure `PageAgentConfig` automatically in `src/entry.ts`.
+Query params configure `PageAgentConfig` in `src/umd.ts`.
 
-## File Organization
+## Key Files Reference
 
-### Core Library (`packages/page-agent/src/`)
+### Page Agent (`packages/page-agent/`)
 
-- `entry.ts` - CDN/UMD entry point with auto-initialization
+| File | Description |
-- `PageAgent.ts` - **Main AI agent class** orchestrating DOM operations
+|------|-------------|
-- `tools/` - Agent tool implementations for web actions
+| `src/PageAgent.ts` | ⭐ Main AI agent class |
-- `ui/` - UI components (Panel, SimulatorMask) with CSS modules
+| `src/umd.ts` | CDN/UMD entry with auto-init |
-- `utils/bus.ts` - **Type-safe event bus** for decoupled communication
+| `src/tools/` | Tool definitions calling PageController |
-- `patches/` - Framework-specific optimizations (React, Antd compatibility)
-- `llms/` - LLM integration and communication layer
-- `dom/` - HTML serialization and page analysis utilities
-- `config/` - Configuration constants and settings
 
-### Website (`packages/website/src/`)
+### LLMs (`packages/llms/`)
 
-- `main.tsx` - Site entry with hash routing setup
+| File | Description |
-- `router.tsx` - **Manual route definitions** (requires explicit registration)
+|------|-------------|
-- `components/DocsLayout.tsx` - Navigation structure (hardcoded nav items)
+| `src/index.ts` | ⭐ LLM class with retry logic |
-- `docs/[section]/[topic]/page.tsx` - Documentation pages
+| `src/types.ts` | MacroToolInput, AgentBrain, LLMConfig |
-- `test-pages/` - Library integration test pages
+| `src/OpenAILenientClient.ts` | OpenAI-compatible client |
+
+### Page Controller (`packages/page-controller/`)
+
+| File | Description |
+|------|-------------|
+| `src/PageController.ts` | ⭐ Main controller class |
+| `src/actions.ts` | Element interactions (click, input, scroll) |
+| `src/dom/dom_tree/index.js` | Core DOM extraction engine |
 
 ## Adding New Features
 
-### New Documentation Page
-
-1. Create `packages/website/src/docs/<section>/<slug>/page.tsx`
-2. Add route to `packages/website/src/router.tsx` with `<Header /> + <DocsLayout>` wrapper
-3. Add navigation item to `DocsLayout.tsx`
-
 ### New Agent Tool
 
-1. Implement under `packages/page-agent/src/tools/`
+1. Implement in `packages/page-agent/src/tools/index.ts`
-2. Export via `packages/page-agent/src/tools/index.ts`
+2. If tool needs DOM ops, add method to PageController first
-3. Wire into `PageAgent.ts` if needed
+3. Tool calls `this.pageController.methodName()` for DOM interactions
 
-### New UI Component
+### New PageController Action
 
-1. Create in `packages/page-agent/src/ui/` with colocated CSS modules
+1. Add implementation in `packages/page-controller/src/actions.ts`
-2. Use event bus for PageAgent communication
+2. Expose via async method in `PageController.ts`
+3. Export from `packages/page-controller/src/index.ts`
 
 ## Code Standards
 
-### TypeScript
-
 - Explicit typing for exported/public APIs
 - ESLint relaxes some unsafe rules for rapid iteration
-
+- All code and comments must be in English.
-### CSS & Styling
-
-- **Prefer Tailwind CSS over custom CSS**
-- Custom CSS variables for theme gradients in `src/index.css`
-- Dark mode support via `dark:` classes
-- CSS modules for component-specific styles
-
-### Import Organization
-
-- External libraries first
-- Internal modules (`@/`, `@pages/`)
-- Relative imports last
-- Blank lines between groups
-
-## Critical Files to Understand
-
-- `packages/page-agent/src/PageAgent.ts` - Core AI agent class with DOM manipulation
-- `packages/page-agent/src/dom/dom_tree/index.js` - DOM extraction engine
-- `packages/page-agent/src/utils/bus.ts` - Type-safe event bus system
-- `packages/page-agent/src/entry.ts` - Library entry point for CDN usage
-- `packages/page-agent/vite.config.js` - Library build configuration
-
-- `packages/website/src/router.tsx` - Central routing definition (manual registration required)
-- `packages/website/src/components/DocsLayout.tsx` - Navigation structure
-- `packages/website/vite.config.js` - Website build configuration
-
-## Debugging Common Issues
-
-### Blank Documentation Pages
-
-1. Verify route exists in `packages/website/src/router.tsx`
-2. Check component import path
-3. Verify CSS isn't hiding content (check dark mode classes)
-4. Test with minimal component first
-
-### Library Integration Issues
-
-1. Check `packages/page-agent/dist/lib/page-agent.umd.js` builds correctly
-2. Test CDN injection with query params
-3. Verify event bus communications are properly typed
-4. Use `packages/website/src/test-pages/` for isolated testing

+### CDN Integration
+
+Fastest way to try PageAgent is to include it via CDN. Demo model will be used by default.

-
-The development progress and future plans for PageAgent.
-
-## 🚀 Current Works
-
-- [x] **MVP** 
-  - Core functionality implemented.
-- [x] **SPA interaction** 
-- [x] **Reasoning and (short) memory**
-- [x] **Multi model provider integration and testing**
-- [x] **UI with HITL** 
-  - Human-in-the-loop user interface. Agent can ask user questions.
-- [x] **Landing and doc pages**
-- [x] **Remove `ai-sdk`** 
-  - Only one function of AI-ADK is being used.
-  - Our agent memory and thinking mechanism does not suite ai-sdk.
-- [x] **Robust LLM output**
-  - Auto-fix incomplete output format of DeepSeek and QWen.
-- [x] **Working homepage with live LLM API**
-- [x] **~~free~~ CDN**
-- [x] **Free evaluation plan**
-- [x] **Custom actions and HITL**
-- [ ] **Hooks and Events**
-  - [x] **lifecycle hooks**
-  - [ ] **lifecycle events**
-- [ ] **❗Pause and intervene** 
-  - Current pause does not allow user intervention.
-- [ ] **❗Hijack `page_open/page_change/page_unload` behavior**
-- [ ] **Custom knowledge base and instructions**
-- [ ] **Black/white-list safeguard**
-- [ ] **Data-masking**
-- [ ] **Improve Memory**
-  - Current phrasing can cause logic-loop for some models.
-  - Test adding `Action` to memory.
-- [ ] **Tools for more complex tasks**
-  - todo list
-  - file sys
-- [ ] **Optimize for popular UI frameworks**
-- [x] **i18n of the website**
-  - [x] Chinese version
-  - [x] English version
-- [ ] **Testing suits**
-- [ ] **Support custom llm fetch**
-- [ ] **Refactor: Separate `Agent` and `Page-Controller`** 
-  - Agent should be able to run w/o dom. 
-  - Actions should be able to be injected through iframe.
-
-♻️ Following browser-use's update and contribute back.
-
-## 📋 Pending Features
-
-- [ ] **Chrome-ext wrapper**
-- [ ] **Same-origin multi-page-app rally**
-- [ ] **Local MCP proxy**
-
-## 🤔 To Be Decided
-
-- [ ] **Cross-origin multi-page?** 
-  - Tricky
-  - Need some kind of "memory rally"

+# @page-agent/llms
+
+LLM client with a **reflection-before-action** mental model for page-agent.
+
+## Why This Package Exists
+
+The LLM module and the agent logic are inherently coupled. This package exists not to decouple them, but to **define the interface contract** between the LLM and the agent.
+
+The core abstraction is the `MacroToolInput` — a structured output format that **forces the model to reflect before acting**.
+
+## The Reflection-Before-Action Model
+
+Every tool call must first output its reasoning state before the actual action:
+
+```typescript
+interface MacroToolInput {
+  // Reflection (mandatory before any action)
+  evaluation_previous_goal?: string  // How well did the previous action work?
+  memory?: string                     // Key information to remember
+  next_goal?: string                  // What to accomplish next
+
+  // Action (the actual operation)
+  action: Record<string, any>
+}
+```
+
+This design ensures that:
+
+1. **The model evaluates its previous action** before deciding the next step
+2. **Working memory is explicitly maintained** across conversation turns
+3. **Goals are clearly stated**, making the agent's reasoning transparent and debuggable
+
+## Key Components
+
+| Export | Description |
+|--------|-------------|
+| `LLM` | Main LLM client class with retry logic |
+| `MacroToolInput` | The reflection-before-action input schema |
+| `AgentBrain` | Agent's thinking state (eval, memory, goal) |
+| `LLMConfig` | Configuration for LLM connection |
+| `parseLLMConfig` | Parse and apply defaults to config |

+# Website Package - Instructions for Coding Assistants
+
+## Tech Stack
+
+- **React** with TypeScript
+- **Vite** for dev server and build
+- **Tailwind CSS** for styling
+- **shadcn/ui** (new-york style) for UI components
+- **Magic UI** for animations and effects
+- **wouter** with hash routing for static hosting
+- **lucide-react** for icons
+
+## Component Guidelines
+
+### Use shadcn/ui Components First
+
+**ALWAYS prefer shadcn/ui components over custom implementations.**
+
+Before creating any UI component, check if shadcn already provides it:
+
+```bash
+# IMPORTANT: Run from packages/website/, NOT from repo root
+cd packages/website
+
+# Add a new shadcn component
+npx shadcn@latest add <component-name>
+
+# Add a Magic UI component
+npx shadcn@latest add "@magicui/<component-name>"
+```
+
+Available shadcn components: https://ui.shadcn.com/docs/components
+Available Magic UI components: https://magicui.design/docs/components
+
+### Current UI Components
+
+Located in `src/components/ui/`:
+
+**From shadcn/ui:**
+
+- `alert`, `badge`, `button`, `separator`, `sonner`, `switch`, `tooltip`
+
+**From Magic UI:**
+
+- `animated-gradient-text`, `animated-shiny-text`, `aurora-text`
+- `hyper-text`, `magic-card`, `neon-gradient-card`, `particles`
+- `sparkles-text`, `text-animate`, `typing-animation`
+
+**Custom:**
+
+- `highlighter`, `kbd`, `spinner`
+
+### Styling Rules
+
+1. **Prefer Tailwind classes** over custom CSS
+2. Use CSS modules only for complex component-specific styles
+3. Support dark mode via `dark:` classes
+4. Use CSS variables from `src/index.css` for theme colors
+
+## Project Structure
+
+```
+src/
+├── pages/
+│   ├── Home.tsx         # Homepage
+│   └── docs/
+│       ├── Layout.tsx   # Documentation sidebar
+│       └── [section]/[topic]/page.tsx
+├── components/
+│   ├── ui/              # shadcn/ui + Magic UI components
+│   ├── Header.tsx       # Site header
+│   └── Footer.tsx       # Site footer

+├── router.tsx           # Central routing
+└── main.tsx             # App entry
+```
+
+## Adding New Pages
+
+### Documentation Page
+
+1. Create `src/pages/docs/<section>/<slug>/page.tsx`
+2. Add route to `src/router.tsx` with `<Header /> + <DocsLayout>` wrapper
+3. Add navigation item to `pages/docs/Layout.tsx`
+
+## Routing
+
+Uses hash-based routing for static hosting:
+
+```tsx
+import { Router } from 'wouter'
+import { useHashLocation } from 'wouter/use-hash-location'
+
+;<Router hook={useHashLocation}>{/* routes */}</Router>
+```
+
+## Configuration Files
+
+| File              | Purpose                 |
+| ----------------- | ----------------------- |
+| `components.json` | shadcn/ui configuration |
+| `vite.config.js`  | Vite build settings     |
+| `tsconfig.json`   | TypeScript config       |
+
+## Commands
+
+```bash
+npm start        # Dev server (from root)
+npm run build:website    # Build website (from root)
+```
