+
+## Reporting a Vulnerability
+
+Please do not report security vulnerabilities through public GitHub issues, discussions, or pull requests.
+
+Use GitHub's private vulnerability reporting flow:
+
+- Open https://github.com/alibaba/page-agent/security/policy
+- Click `Report a vulnerability`
+
+If private reporting is unavailable, open a minimal public issue only to request a private contact channel. Do not include exploit details.
+
+## What to Include
+
+- Affected package or feature
+- Exact version, commit, or build
+- Browser, OS, and runtime environment
+- Reproduction steps or a proof of concept
+- Expected impact
+
+## Scope
+
+We prioritize reports that show a real security boundary failure, such as:
+
+- Unauthorized access to data, tokens, or extension capabilities
+- Bypassing explicit safety constraints
+- Sensitive data exposure caused by default behavior
+
+The following usually do not qualify by themselves:
+
+- Unsafe custom integrations that ignore documented safeguards
+- Intentionally embedding secrets into client-side builds
+- Reports against unsupported older versions
+
+## Disclosure
+
+Please avoid public disclosure until maintainers have had a reasonable chance to investigate and ship a fix.

@@ -5,6 +5,63 @@ All notable changes to this project will be documented in this file.
 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
 and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
 
+## [1.5.1] - 2026-03-05
+
+### Breaking Changes
+
+- **`data-browser-use-ignore` → `data-page-agent-ignore`** - DOM ignore attribute renamed to match the project identity
+- **Config types restructured** - `PageAgentConfig` split into `AgentConfig` + `PageAgentCoreConfig`; config definitions moved from `config/index.ts` to `types.ts`
+- **Zod v3/v4 dual support** - Libraries now accept both `zod@^3.25` and `zod@^4.0` as peer dependencies
+
+### Features
+
+- **Experimental `llms.txt` support** - Agent can fetch and include a site's `llms.txt` in context. Enable via `experimentalLlmsTxt: true`
+
+### Improvements
+
+- Default `maxSteps` changed from 20 to 40 for better for complex tasks out of the box
+- Added 400ms wait between agent steps for page reactions
+- Increased click wait time (100ms → 200ms) for more reliable interactions
+- Removed debug `console.log` statements from scroll actions
+- Reset observations on new task start
+- Improved logging across packages
+
+### Extension v0.1.9
+
+> PageAgent 1.5.1
+
+- **Advanced config panel** - New collapsible section exposing Max Steps, System Instruction, and experimental `llms.txt` toggle
+- Streamlined User Auth Token description
+- Moved testing API notice below auth token section
+
+---
+
+## [1.4.0] - 2026-02-27
+
+### Features
+
+- Update Terms of Use and Privacy Policy
+- **Robust tool-call validation** - Action inputs are now validated against tool schemas individually, producing clear error messages (e.g. `Invalid input for action "click_element_by_index"`) instead of unreadable union parse errors
+- **Primitive action input coercion** - Small models that output `{"click_element_by_index": 2}` instead of `{"click_element_by_index": {"index": 2}}` are now auto-corrected using tool schemas
+- **Qwen model updates** - Added `qwen3.5-plus` as the default free testing model; disabled `enable_thinking` for Qwen models to avoid incompatible responses
+- **Updated default LLM endpoint** - Migrated demo and extension to a new testing endpoint with legacy endpoint auto-migration
+
+### Improvements
+
+- Unified zod imports (`* as z`) across all packages for consistency
+- Better Zod error formatting with `z.prettifyError()` in LLM client
+- Exported `InvokeError` and `InvokeErrorType` as values (not just types) from `@page-agent/llms`
+- Exported `SupportedLanguage` type from `@page-agent/core`
+
+### Extension v0.1.8
+
+- **Language setting** - Added language selector (System / English / 中文) in config panel
+- **UI makeover** - New empty state with breathing glow and typing animation; ai-motion glow overlay while running; refined focus styles
+- **Testing endpoint notice** - Shows terms of use notice when using the free testing API
+- **Legacy endpoint migration** - Auto-migrates old Supabase testing endpoint to new endpoint on startup

+# Terms of Use & Privacy
+
+**Last updated:** March 2026
+
+"We" in this document refers to the maintainers of the open-source Page Agent project (https://github.com/alibaba/page-agent). "The software" refers to Page Agent (the JavaScript library) and Page Agent Ext (the browser extension). This document covers the software itself and the testing API we provide — **not** any third-party product or service built with it.
+
+---
+
+## 1. Open Source Software Privacy
+
+The software is a **client-side only** tool with a "Bring Your Own Key" (BYOK) architecture. The software itself does **not** include any backend service. The software does **not** collect or transmit any user data on its own, and we do **not** have access to your browsing activity, page content, or task instructions through the software.
+
+All data transmission occurs **only** between your browser and the LLM provider you configure. You are in full control of which provider receives your data.
+
+The project is open source under the [MIT License](https://github.com/alibaba/page-agent/blob/main/LICENSE) and can be audited at: https://github.com/alibaba/page-agent
+
+---
+
+## 2. Testing API and Demo Disclaimer & Terms of Use
+
+To facilitate easy testing and technical evaluation, we provide a free testing LLM API. This API is used in the project homepage's live demo, the pre-built demo CDN bundles, and the browser extension's default configuration. Users may also use it independently for their own technical evaluation of the software.
+
+This free testing API is provided **strictly for technical evaluation and R&D purposes only**. It must not be used in any production environment. By using this API, you agree to the following terms:
+
+- **Permitted Use Only**: This API must be used solely for technical evaluation of the software. Any other use — including integration into other products or services, unlawful activities, violation of the underlying LLM provider's usage policies, or automated scraping at scale — is strictly prohibited.
+
+- **No Sensitive Data**: You are strictly prohibited from inputting any Personal Identifiable Information (PII), confidential business data, financial/medical records, or using this agent on web pages containing such sensitive information.
+
+- **Data Processing**: We do not store or log your prompts, webpage data (HTML), or any submitted content, nor do we use such data for model training. All data is processed in-transit and immediately discarded. We perform in-memory request validation to prevent abuse of the testing API, and temporarily process IP addresses for rate-limiting purposes. No data from these processes is retained. Data is processed through Alibaba Cloud infrastructure, which is subject to its own privacy policy.
+
+- **Independent Infrastructure**: The software is completely frontend-based with a "Bring Your Own Key" (BYOK) architecture and **no built-in backend**. To facilitate easy testing, the maintainers have purchased public cloud services from Alibaba Cloud China ([aliyun.com](https://www.aliyun.com) Function Compute and BaiLian Qwen models). This project is not a product of, nor endorsed by, Alibaba Cloud.
+
+- **No Guaranteed Availability**: This testing API may be rate-limited, degraded, or discontinued at any time without prior notice.
+
+- **"AS IS" & Limitation of Liability**: This service is provided strictly on an "AS IS" and "AS AVAILABLE" basis, without any warranties. The maintainers bear no liability for any data loss, service interruption, or legal consequences arising from your use of this service.
+
+- **Recommendation for Real Usage**: For secure and continuous usage, we strongly advise using the BYOK mode with your own legally compliant commercial LLM API keys, or connecting to local, offline models (e.g., Ollama).
+
+**Note**: This free testing LLM API processes data via servers located in Mainland China. If you are located in a region with strict data localization laws (such as the EU/EEA), please do not use this API.
+
+**Age Requirement**: The software and testing API are not intended for use by individuals under the age of 13 (or the minimum age of digital consent in your jurisdiction).
+
+---
+
+## 3. Browser Extension (Page Agent Ext)
+
+### Data Processing
+
+The extension performs DOM analysis and automation actions **locally in your browser**. Your browsing history, passwords, and form data are not accessed or collected by the extension developer.
+
+Data is transmitted to external servers **only when you initiate an automation task**. When this occurs:
+
+- Your task instructions (natural language commands)
+- Simplified page structure (cleaned HTML) of all pages under the extension's control
+
+are sent to the LLM API endpoint configured in **your settings**.
+
+> **Note:** The HTML cleaning process simplifies page structure for AI readability but **does not guarantee removal of sensitive information** (e.g., visible text, form values, or personal data on the page). Please be mindful of the page content when initiating tasks.
+
+**If you configure a third-party LLM provider** (e.g., OpenAI, Anthropic, or others), data is sent directly to that provider. Their privacy policies apply.
+
+**If you use the testing API**, the terms in [Section 2](#2-testing-api-and-demo-disclaimer--terms-of-use) apply. By using the extension with the default testing API, you agree to those terms.
+
+### Data Storage
+
+- **Local storage only**: Your configuration (API endpoint, API key, model selection) is stored in your browser via `chrome.storage.local` (or equivalent browser storage APIs)
+- **No cloud sync**: Configuration is not synced to any external server
+- **No analytics**: The extension does not include any analytics or tracking code
+
+### Your Control
+
+- The extension is open source and can be audited by anyone
+- You choose which LLM provider to use
+- You may configure your own API endpoint at any time
+- You can clear all stored data by removing the extension
+
+---
+
+## Changes
+
+We may update these terms at our discretion.

 # Privacy Policy for Page Agent Extension
 
-**Last updated:** January 2026
+This document has moved. Please see our full **[Terms of Use & Privacy](../../docs/terms-and-privacy.md)**.
 
-## Overview
+Online: https://github.com/alibaba/page-agent/blob/main/docs/terms-and-privacy.md
-
-Page Agent Extension is a browser automation tool that uses AI to help you interact with web pages. This policy explains what data is processed and under what circumstances.
-
-## Data Processing
-
-### Local Processing
-
-The extension performs DOM analysis and automation actions **locally in your browser**. Your browsing history, passwords, and form data are not accessed or collected by the extension itself.
-
-### Data Transmission
-
-Data is transmitted to external servers **only when you initiate an automation task**. When this occurs:
-
-- Your task instructions (natural language commands)
-- Sanitized page structure (simplified DOM, excluding sensitive form values)
-
-are sent to the LLM API endpoint configured in **your settings**.
-
-**If you configure a third-party LLM provider** (e.g., OpenAI, Anthropic, or others), data is sent directly to that provider. Their privacy policies apply.
-
-**If you use our testing endpoint**, your requests are proxied to [DeepSeek](https://deepseek.com) for AI processing. Regarding this test endpoint:
-
-- This endpoint is provided for evaluation purposes only and is not recommended for production or daily use
-- We do **not** store your task content, page content, or visited URLs
-- Minimal logging (timestamps, request metadata, IP addresses) may occur for abuse prevention and service stability
-- DeepSeek's [Privacy Policy](https://cdn.deepseek.com/policies/en-US/deepseek-privacy-policy.html) applies to their processing of your requests
-
-## Data Storage
-
-- **Local storage only**: Your configuration (API endpoint, API key, model selection) is stored in your browser via `chrome.storage.local`
-- **No cloud sync**: Configuration is not synced to any external server
-- **No analytics**: The extension does not include any analytics or tracking code
-
-## Your Control
-
-- The extension is open source and can be audited by anyone
-- You choose which LLM provider to use
-- You may configure your own API endpoint at any time
-- You can clear all stored data by removing the extension
-
-## Changes to This Policy
-
-We may update this policy as the extension evolves. Significant changes will be noted in the extension's release notes.
-
-## Contact
-
-For questions about this privacy policy:

-# Page Agent 浏览器插件 API
-
-在你的网页应用中接入 Page Agent 插件，并通过页面 JavaScript 发起多页面浏览器任务。
-
-## 安装
-
-### 1. 安装浏览器插件
-
-首选渠道：
-
-- Chrome 应用商店：https://chromewebstore.google.com/detail/page-agent-ext/akldabonmimlicnjlflnapfeklbfemhj
-
-通常更快提供最新构建的渠道：
-
-- GitHub Releases：https://github.com/alibaba/page-agent/releases
-
-### 2. 安装类型定义（推荐）
-
-```bash
-npm install @page-agent/core --save-dev
-```
-
-### 3. 授权（Token）
-
-token 用于让页面 JS 调用扩展 API（`window.PAGE_AGENT_EXT`）并执行多页面任务。
-
-为什么必须使用 token：
-
-- 插件具备较广的浏览器权限（页面访问、导航、多标签控制）。
-- 若被滥用，可能危害用户隐私与安全。
-- 用户必须主动将 token 提供给其信任的应用。
-
-配置步骤：
-
-1. 在扩展侧边栏中复制 auth token。
-2. 在页面中设置 token：
-
-```typescript
-localStorage.setItem('PageAgentExtUserAuthToken', 'your-token')
-```
-
-## 快速开始
-
-```typescript
-import type {
-  AgentActivity,
-  AgentStatus,
-  ExecutionResult,
-  HistoricalEvent,
-} from '@page-agent/core'
-
-// 等待插件注入（最多 1 秒）
-async function waitForExtension(timeout = 1000): Promise<boolean> {
-  const start = Date.now()
-  while (Date.now() - start < timeout) {
-    if (window.PAGE_AGENT_EXT) return true
-    await new Promise((r) => setTimeout(r, 100))
-  }
-  return false
-}
-
-// 使用
-if (await waitForExtension()) {
-  const result = await window.PAGE_AGENT_EXT!.execute('点击登录按钮', {
-    baseURL: 'https://api.openai.com/v1',
-    apiKey: 'your-api-key',
-    model: 'gpt-5.2',
-    onStatusChange: (status) => console.log('状态:', status),
-    onActivity: (activity) => console.log('活动:', activity),
-  })
-  console.log('结果:', result)
-}
-```
-
-## 全局 API
-
-token 匹配后，插件会在 `window` 上注入 API。
-
-### `window.PAGE_AGENT_EXT_VERSION`
-
-插件版本号字符串，可用于在访问主 API 前做能力检查。
-
-### `window.PAGE_AGENT_EXT`
-
-主命名空间对象。
-
-#### `PAGE_AGENT_EXT.execute(task, config)`
-
-执行 Agent 任务。
-
-参数：
-
-| 名称 | 类型 | 必填 | 说明 |
-| ---- | ---- | ---- | ---- |
-| `task` | `string` | 是 | 任务描述 |
-| `config` | `ExecuteConfig` | 是 | LLM 设置、执行选项和回调 |
-
-返回：`Promise<ExecutionResult>`
-
-#### `PAGE_AGENT_EXT.stop()`
-
-停止当前任务。
-
-## 类型定义
-
-安装 `@page-agent/core` 获取完整类型：
-
-```typescript
-import type {
-  AgentActivity,
-  AgentStatus,
-  ExecutionResult,
-  HistoricalEvent,
-} from '@page-agent/core'
-
-export interface ExecuteConfig {
-  baseURL: string
-  apiKey: string
-  model: string
-
-  // 是否包含启动脚本所在标签页。默认 true。
-  includeInitialTab?: boolean
-
-  onStatusChange?: (status: AgentStatus) => void
-  onActivity?: (activity: AgentActivity) => void
-  onHistoryUpdate?: (history: HistoricalEvent[]) => void
-}
-
-export type Execute = (task: string, config: ExecuteConfig) => Promise<ExecutionResult>
-```
-
-`AgentStatus`
-
-```typescript
-type AgentStatus = 'idle' | 'running' | 'completed' | 'error'
-```
-
-`AgentActivity`
-
-```typescript
-type AgentActivity =
-  | { type: 'thinking' }
-  | { type: 'executing'; tool: string; input: unknown }
-  | { type: 'executed'; tool: string; input: unknown; output: string; duration: number }
-  | { type: 'retrying'; attempt: number; maxAttempts: number }
-  | { type: 'error'; message: string }
-```
-
-`HistoricalEvent`
-
-```typescript
-type HistoricalEvent =
-  | { type: 'step'; stepIndex: number; reflection: AgentReflection; action: Action }
-  | { type: 'observation'; content: string }
-  | { type: 'user_takeover' }
-  | { type: 'retry'; message: string; attempt: number; maxAttempts: number }
-  | { type: 'error'; message: string; rawResponse?: unknown }
-```
-
-`ExecutionResult`
-
-```typescript
-interface ExecutionResult {
-  success: boolean
-  data: string
-  history: HistoricalEvent[]
-}
-```
-
-## 使用示例
-
-### 基础执行
-
-```typescript
-const result = await window.PAGE_AGENT_EXT!.execute(
-  '在邮箱输入框填入 test@example.com 然后点击提交',
-  {
-    baseURL: 'https://api.openai.com/v1',
-    apiKey: process.env.OPENAI_API_KEY!,
-    model: 'gpt-5.2',
-    includeInitialTab: false, // 可选：排除当前标签页
-    onStatusChange: (status) => console.log(status),
-    onActivity: (activity) => console.log(activity),
-  }
-)
-```
-
-### 停止当前任务
-
-```typescript
-window.PAGE_AGENT_EXT!.stop()
-```
-
-## Window 类型声明
-
-如果你不直接引入 `@page-agent/core`，可添加以下声明：
-
-```typescript
-import type {
-  AgentActivity,
-  AgentStatus,
-  ExecutionResult,
-  HistoricalEvent,
-} from '@page-agent/core'
-
-interface ExecuteConfig {
-  baseURL: string
-  apiKey: string
-  model: string
-  includeInitialTab?: boolean
-  onStatusChange?: (status: AgentStatus) => void
-  onActivity?: (activity: AgentActivity) => void
-  onHistoryUpdate?: (history: HistoricalEvent[]) => void
-}
-
-declare global {
-  interface Window {
-    PAGE_AGENT_EXT_VERSION?: string
-    PAGE_AGENT_EXT?: {
-      version: string
-      execute: Execute
-      stop: () => void
-    }
-  }
-}
-```

+## Routing
+
+Uses wouter browser routing with base path for GitHub Pages deployment at `https://alibaba.github.io/page-agent/`.
+
+```tsx
+// main.tsx
+<Router base="/page-agent">
+  <PagesRouter />
+</Router>
+```
+
+**Key rules:**
+
+- Header and Footer live in `router.tsx` **outside** `<Switch>`, so they always see the root router context (`base="/page-agent"`)
+- Docs pages are nested via `<Route path="/docs" nest>`, which creates a child context (`base="/page-agent/docs"`)
+- Inside the docs nest, Link hrefs are relative to `/docs` (e.g. `href="/features/models"`, NOT `href="/docs/features/models"`)
+- **Never use `~` prefix** in Link hrefs — it bypasses the base path entirely
+- Doc page headings use `<Heading id="slug" level={2}>` for anchor links
+
+### SPA on GitHub Pages
+
+Instead of `404.html` redirects, the build copies `index.html` into every route directory. Add new routes to the `SPA_ROUTES` array in `vite.config.js`.
+
 ## 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
+2. Add route in `src/pages/docs/index.tsx`
-3. Add navigation item to `pages/docs/Layout.tsx`
+3. Add navigation item in `src/pages/docs/Layout.tsx`
-
+4. Add path to `SPA_ROUTES` in `vite.config.js`
-## 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>
-```
