-description: Build, lint, and env guidance for this repo
----
-### Build and env
-
-- **Dev**: `npm run dev` starts Vite with base `./` and React SWC, Tailwind v4 plugin. Hash routing is required; use `useHashLocation`.
-- **App build**: `npm run build` runs TypeScript build then Vite static build to `dist/` (site) and then `npm run build:lib`.
-- **Library build**: `vite.lib.config.ts` builds UMD and ES to `dist/lib/` with entry `src/entry.ts`, file name `page-agent`.
-- **Env injection**: `vite.config.ts` defines `import.meta.env.OPEN_ROUTER_*` from real env. When adding new env vars, add them under `define` in `vite.config.ts` and reference via `import.meta.env.*`.
-- **Base path**: keep `base: './'` in both dev and build to make hash routing work under static hosting. If you change it, review `pages/main.tsx` URL logic.
-
-### ESLint & TypeScript
-
-- **Lint**: Config in `eslint.config.js` uses TypeScript ESLint with type‑aware rules, React plugins, and relaxed unsafe checks for rapid iteration. Run `npm run lint` or rely on lint‑staged.
-- **TypeScript**: `tsconfig.app.json` is strict with `noEmit` and bundler resolution. Use `@/*` alias per config. Prefer explicit types on exported functions and public classes.
-
-### Output hygiene
-
-- Never commit changes under `dist/` manually. If you need to test CDN/UMD output locally, run library build and open `dist/index.html` or consume `dist/lib/page-agent.umd.cjs`.
-- Do not import from `dist/` in source files. Always import from `src/`.
-
-### Routing & deploy gotchas
-
-- This site is SPA with hash routing. Ensure hosting serves `index.html` and does not rewrite hash routes.
-- When embedding via CDN bookmarklet, the script is `dist/lib/page-agent.umd.cjs`. Query param `?model=` is parsed in `src/entry.ts`.

-### Project structure and navigation map
-
-- **Library entry (CDN/UMD)**: Public script entry is `src/entry.ts`. It attaches `PageAgent` to `window` and auto-initializes if injected via a `<script>` tag. Library build outputs to `dist/lib/` with file name `page-agent.*`.
-
-- **Main Page entry**: `pages/main.tsx` mounts a `wouter` `Router` with `useHashLocation`. Routes delegate to:
-  - `pages/router.tsx` for docs/marketing pages
-  - `pages/test-pages/router.tsx` for internal test pages under `#/test-pages`
-
-- **Docs layout**: Use `pages/components/DocsLayout.tsx` for all docs pages. When adding a new doc page, add it to:
-  - the navigation in `DocsLayout.tsx`, and
-  - the switch in `pages/router.tsx` with `<Header /> + <DocsLayout>...` wrapper
-
-- **Hash routing**: Always use hash routes (e.g. `#/docs/...`). The `Router` is created as:
-  - `createRoot(...).render(<Router hook={useHashLocation}> ...)`
-  - Base URL in dev is `/`; otherwise computed relative to `index.html`. Do not change `vite.config.ts` base from `./` without updating `pages/main.tsx`.
-
-- **Aliases**: Use `@/` as alias for `src/` and `@pages/` as alias for `pages/` (set in both Vite configs). Prefer absolute alias imports over deep relative chains.
-
-- **Styling**: Tailwind v4 is enabled via `@tailwindcss/vite`. Use semantic utility classes; avoid ad‑hoc inline styles.
-
-- **Do not edit generated files**: Never edit anything under `dist/`. Add sources under `src/` and let builds emit artifacts.
-
-- **Event bus**: Type-safe event system for decoupling components, primarily used for PageAgent-UI communication.
-
-### Conventions
-
-- **Routing (wouter)**:
-  - Prefer `<Route path="/segment" component={Page} />` for simple pages; use children form when wrapping with layout.
-  - Keep 404 as the final catch‑all `Route` in `pages/router.tsx`.
-  - For test pages, mount under `#/test-pages` only.
-
-- **Docs pages**: Place in `pages/docs/**/page.tsx`. Export a default React component. Pages are rendered inside `DocsLayout` and must be linked in the sidebar.
-
-- **Typescript**:
-  - TS strict is enabled; however, ESLint relaxes many unsafe rules for DX. Keep exported/public APIs typed explicitly.
-  - JSX runtime is `react-jsx` (React 19).
-
-- **Global objects**: The library exposes `window.PageAgent` and `window.pageAgent`. Guard re‑injection by disposing `window.pageAgent` before re‑creating, as done in `src/entry.ts`.
-
-### Core modules (src/)
-
-- **PageAgent.ts**: Core agent implementation and public API
-- **entry.ts**: Library entry point for CDN/UMD usage
-- **config/**: Configuration constants and settings management
-- **tools/**: Agent tool implementations for web actions and page manipulation
-- **ui/**: User interface components (Panel, SimulatorMask, etc.) for agent visualization
-- **llms/**: LLM integration and communication layer
-- **dom/**: HTML serialization, page analysis utilities, and DOM manipulation helpers
-- **utils/**: Shared utilities including the type-safe event bus system
-- **patches/**: Framework-specific optimizations and compatibility fixes (React, Antd, etc.)
-- **prompts/**: System prompts and LLM instruction templates
-- **i18n/**: Internationalization and language support
-
-### Site structure (pages/)
-
-- **pages/**: Documentation site and marketing pages
-- **pages/test-pages/**: Demo pages for testing agent capabilities
-
-### When adding features
-
-- New docs page: create `pages/docs/<section>/<slug>/page.tsx`, add route and sidebar link.
-- New tool: implement under `src/tools/`, export via `src/tools/index.ts`, wire into `PageAgent` if needed.
-- Visual tweaks: edit under `src/ui/` and keep styles in colocated CSS modules.

-# page-agent AI Coding Instructions
-
-## Project Overview
-
-This project has **TWO SEPARATE PARTS**:
-
-1. **Core Library** (`src/`) - Pure JavaScript AI agent library that can be injected into any webpage
-2. **Marketing Website** (`pages/`) - React web app for landing page and documentation
-
-## Architecture & Tech Stack
-
-### Core Library (`src/`) - Pure JavaScript AI Agent
-
-- **Technology**: Vanilla JavaScript/TypeScript (no React dependency)
-- **Purpose**: AI agent with DOM automation capabilities
-- **Output**: UMD/ES modules via `vite.lib.config.ts`
-- **Key Features**: DOM processing, LLM integration, type-safe event bus
-
-### Marketing Website (`pages/`) - React Web App
-
-- **Technology**: React 19 + TypeScript + Wouter routing + Tailwind CSS v4
-- **Purpose**: Landing page and documentation site
-- **Output**: Static website via `vite.config.ts`
-- **Usage**: Hosted documentation and demos
-
-## Critical Development Workflows
-
-### Dual Build System - Two Separate Projects
-
-```bash
-npm start                    # React website (pages/) development
-npm run build               # Build BOTH library AND website
-npm run build:lib           # Pure JS library only (src/ → dist/lib/)
-npm run build:lib:watch     # Library development with auto-rebuild
-```
-
-### Library Development (Pure JavaScript)
-
-**Working on the core AI agent (`src/`):**
-
-1. Edit pure JavaScript/TypeScript files in `src/`
-2. Use `npm run build:lib:watch` for development
-3. Test via CDN injection: `<script src="dist/lib/page-agent.umd.js"></script>`
-4. No React dependencies allowed in `src/`
-
-### Website Development (React)
-
-**Working on marketing/docs (`pages/`):**
-
-1. Use `npm start` for React development server
-2. Can import from `src/` via `@/` alias to demo library features
-3. Create test pages in `pages/test-pages/` to validate library integration
-
-### DOM Pipeline
-
-1. **DOM Extraction**: `src/dom/` converts live DOM to `FlatDomTree`
-2. **Dehydration**: DOM tree → simplified text representation for LLM
-3. **LLM Processing**: Send text to AI model for action planning
-4. **Indexed Operations**: Map LLM responses back to specific DOM elements via indices
-
-### Event Bus Communication
-
-Use `src/utils/bus.ts` instead of prop drilling for PageAgent ↔ UI communication:
-
-```typescript
-// Emit events from PageAgent
-getEventBus().emit('panel:show', undefined)
-getEventBus().emit('panel:update', { status: 'thinking', message: 'Processing...' })
-
-// Listen in UI components
-getEventBus().on('panel:show', () => panel.show())
-```
-
-## Key Patterns & Conventions
-
-### Strict Module Boundaries
-
-- **Core library** (`src/`): Never import from `pages/` - must remain pure JavaScript
-- **React website** (`pages/`): Can import from `src/` via `@/` alias to demo features
-- **Entry points**: `src/entry.ts` (CDN/UMD), `pages/main.tsx` (React website)
-
-### Manual Route Registration Pattern
-
-Routes in `pages/router.tsx` require explicit definition:
-
-```tsx
-<Route path="/docs/features/dom-operations">
-	<div className="min-h-screen bg-white dark:bg-gray-900">
-		<Header />
-		<DocsLayout>
-			<DomOperations />
-		</DocsLayout>
-	</div>
-</Route>
-```
-
-**Adding new docs pages**: 1) Add route to `router.tsx`, 2) Add nav item to `DocsLayout.tsx`
-
-### Hash Routing Requirement
-
-Uses wouter with `useHashLocation` for static hosting compatibility:
-
-```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.
-
-### CSS & Design System
-
-- **Prefer Tailwind CSS over custom CSS** - Use utility classes for styling
-- Custom CSS variables in `src/index.css` define theme gradients:
-  ```css
-  --theme-color-1: rgb(88, 192, 252);
-  --theme-color-2: rgb(189, 69, 251);
-  ```
-- Design follows modern SaaS aesthetic with blue/purple gradients
-- **Accessibility**: Ensure proper contrast ratios, semantic HTML, ARIA labels
-- Dark mode support throughout via Tailwind `dark:` classes
-- Responsive grid layouts for features and content sections
-
-## File Organization
-
-### Core Library (`src/`)
-
-- **PageAgent.ts**: Core agent implementation and public API
-- **entry.ts**: Library entry point for CDN/UMD usage
-- **config/**: Configuration constants and settings management
-- **tools/**: Agent tool implementations for web actions and page manipulation
-- **ui/**: User interface components (Panel, SimulatorMask, etc.) for agent visualization
-- **llms/**: LLM integration and communication layer
-- **dom/**: HTML serialization, page analysis utilities, and DOM manipulation helpers
-- **utils/**: Shared utilities including the type-safe event bus system
-- **patches/**: Framework-specific optimizations and compatibility fixes (React, Antd, etc.)
-- **prompts/**: System prompts and LLM instruction templates
-- **i18n/**: Internationalization and language support
-
-### Documentation Site (`pages/`)
-
-- `main.tsx` - Site entry point with hash routing setup
-- `router.tsx` - Manual route definitions (requires explicit registration)
-- `components/DocsLayout.tsx` - Navigation structure (hardcoded nav items)
-- `docs/[section]/[topic]/page.tsx` - Documentation pages
-- `test-pages/` - Library integration test pages
-
-## Development Workflow
-
-### Commands
-
-- `npm start` - Development server (Vite)
-- `npm run build` - Production build (TypeScript check + Vite build)
-- `npm run lint` - ESLint with strict TypeScript rules
-
-### Debugging Routing Issues
-
-**Common problem**: Blank pages in docs sections. Debug steps:
-
-1. Verify route exists in `pages/router.tsx`
-2. Check component import path
-3. Test with minimal component first
-4. Verify CSS isn't hiding content (check dark mode classes)
-
-### TypeScript Configuration
-
-- Strict mode enabled with `noUnusedLocals` and `noUnusedParameters`
-- Path alias `@/*` maps to `src/*`
-- ESLint uses strict TypeScript rules but disables some for pragmatism:
-  ```js
-  '@typescript-eslint/no-non-null-assertion': 'off'
-  '@typescript-eslint/no-unsafe-assignment': 'off'
-  ```
-
-## Content & Messaging
-
-- **Tone**: Technical but approachable, targeting web developers
-- **Core value prop**: "一行 CDN 引入，为任何网站添加智能 UI Agent"
-- **Differentiator**: Page-embedded vs external automation (vs browser-use)
-- Feature categories: DOM operations, security, data masking, knowledge injection, model integration
-
-## Code Quality Standards
-
-- Use TypeScript strict mode
-- Prefer functional components with hooks
-- **Prefer Tailwind CSS over custom CSS** - Use utility classes for styling
-- Consistent file naming: kebab-case for multi-word files
-- Import organization: React imports first, then components, then styles
-
-## Critical Files to Understand
-
-- `pages/router.tsx` - Central routing definition
-- `pages/components/DocsLayout.tsx` - Navigation structure
-- `pages/page.tsx` - Homepage showcasing product features
-- `src/PageAgent.ts` - **Core library**: AI agent class with DOM manipulation
-- `src/dom/dom_tree/index.js` - **DOM extraction engine** (ported from Python)
-- `src/utils/bus.ts` - **Type-safe event bus** for decoupled communication
-- `src/entry.ts` - CDN/UMD entry point with auto-initialization
-- `vite.config.ts` and `vite.lib.config.ts` - Dual build configuration
-- `tsconfig.app.json` - TypeScript strictness settings
-
-## Core Library Architecture
-
-The core library (`src/`) is a standalone AI agent with these key components:
-
-- **PageAgent.ts**: Main agent class managing DOM tree updates, element highlighting, and LLM communication
-- **DOM processing pipeline**: Converts complex web pages into LLM-friendly text while preserving interactive element mappings for precise actions
-- **Event bus system**: Type-safe communication between PageAgent and UI components
