+# Changelog
+
+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
+
+---
+
+## [1.3.0] - 2026-02-13
+
+### Breaking Changes
+
+- **Lifecycle: `stop()` vs `dispose()`** - New `stop()` method to cancel the current task while keeping the agent reusable. `dispose()` is now terminal — a disposed agent cannot be reused. This affects both `PageAgentCore` and `PanelAgentAdapter`.
+
+### Features
+
+- **Panel action button** - The panel button now morphs between Stop (■) and Close (X) based on agent status
+- **Error history** - Errors and max-step failures are now recorded in `history` as `AgentErrorEvent`, making post-task analysis more complete
+
+### Bug Fixes
+
+- **AbortError handling** - `AbortError` is no longer retried by the LLM client, and shows a clean "Task stopped" message instead of a raw error stack
+
+---
+
+## [1.2.0] - 2026-02-11
+
+### Features
+
+- **Observe Phase** - Agent now observes the page before each action, improving decision accuracy on dynamic pages
+- **Better Abort Handling** - Improved `abortSignal` support for cleaner task cancellation
+
+### Improvements
+
+- Pruned system prompts for lower token usage and faster responses
+- Improved error handling during agent steps with better error messages
+- Zod tree-shaking for smaller bundle size
+
+### Bug Fixes
+
+- Fixed indentation lost in DOM extraction caused by `trimLines`
+- Fixed `gpt-5-mini` temperature configuration
+
+---
+
+## [1.1.0] - 2026-02-02
+
+### Features
+
+- **Custom System Prompt** - New `systemPrompt` config option to customize or extend the default system prompt
+- **Chrome Extension** - Extension with multi-tab control, main-world API with token auth, and tab lifecycle management
+
+### Improvements
+
+- Renamed `include_attributes` to `includeAttributes` in PageController config (camelCase consistency)
+- Lazy-loaded mask module for faster initialization
+- Better date formatting and error messages from LLM client
+- Added `rawRequest` to step history for easier debugging
+
+### Bug Fixes
+
+- Fixed CSP errors by using local SVGs for cursor mask instead of inline styles
+- Fixed `AbortError` being incorrectly retried and shown to users
+- Fixed mask not working correctly when starting a new task after stopping a previous one
+
+---
+
+## [1.0.0] - 2026-01-19

+## 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
+
+---
+

 	- Webpage can be broken. All webpages or apps have bugs. Some bug will make it hard for your job. It's encouraged to tell user the problem of current page. Your feedbacks (including failing) are valuable for user.
-	- Trying to hard can be harmful. Repeating some action back and forth or pushing for a complex procedure with little knowledge can cause unwanted result and harmful side-effects. User would rather you to complete the task with a fail.
+	- Trying too hard can be harmful. Repeating some action back and forth or pushing for a complex procedure with little knowledge can cause unwanted results and harmful side-effects. User would rather you complete the task with a fail.
 - If you do not have knowledge for the current webpage or task. You must require user to give specific instructions and detailed steps.

 # 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
-
-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:

+### 3. Authorization (Token)
 
-The extension only injects APIs when it detects a valid token in `localStorage`.
+The token allows your page JS to call the extension API (`window.PAGE_AGENT_EXT`) and execute multi-page tasks.
 
-1. Open the extension's side panel to get your authorization token
+Why token-based access is required:
+
+- The extension has broad browser permissions (page access, navigation, multi-tab control).
+- If abused, it can harm user privacy and security.
+- Users must explicitly provide the token only to applications they trust.
+
+Setup:
+
+1. Open the extension side panel and copy your auth token.
 2. Set the token in your page:

-# Page Agent 浏览器插件 API
-
-本文档介绍如何在网页应用中接入 Page Agent 浏览器插件。
-
-## 安装
-
-### 1. 安装浏览器插件
-
-从 Chrome 应用商店安装 Page Agent 插件。
-
-### 2. 安装类型定义（推荐）
-
-```bash
-npm install @page-agent/core --save-dev
-```
-
-### 3. 配置认证
-
-插件在页面加载后检测 `localStorage` 中的 token，匹配时才会注入 API。
-
-1. 打开插件的侧边栏面板，获取授权 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
-
-插件在 `window` 对象上注入以下 API：
-
-### `window.PAGE_AGENT_EXT_VERSION`
-
-插件版本号字符串（例如 `"1.0.0"`）。单独暴露版本号，方便在访问主 API 对象前进行版本检查。
-
-### `window.PAGE_AGENT_EXT`
-
-主 API 命名空间对象，包含：
-
-#### `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 | 执行配置（LLM 设置、选项和事件回调） |
-
-**返回：** `Promise<ExecutionResult>`
-
-#### `PAGE_AGENT_EXT.dispose()`
-
-停止并销毁当前运行的 Agent。
-
-## 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
-
-  /**
-   * 是否将初始标签页（运行此脚本的页面）包含在任务中。
-   * @default true
-   */
-  includeInitialTab?: boolean
-
-  onStatusChange?: (status: AgentStatus) => void
-  onActivity?: (activity: AgentActivity) => void
-  onHistoryUpdate?: (history: HistoricalEvent[]) => void
-  onDispose?: () => void
-}
-
-export type Execute = (task: string, config: ExecuteConfig) => Promise<ExecutionResult>
-```
-
-### AgentStatus
-
-```typescript
-type AgentStatus = 'idle' | 'running' | 'completed' | 'error'
-```
-
-| 状态 | 说明 |
-|------|------|
-| `idle` | 空闲，准备执行 |
-| `running` | 正在执行任务 |
-| `completed` | 任务成功完成 |
-| `error` | 任务执行失败 |
-
-### 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 }
-```
-
-| 类型 | 说明 |
-|------|------|
-| `thinking` | Agent 正在分析页面并规划 |
-| `executing` | 正在执行工具操作 |
-| `executed` | 工具执行完成 |
-| `retrying` | 失败后重试 |
-| `error` | 发生错误 |
-
-### 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',
-  }
-)
-
-if (result.success) {
-  console.log('任务完成:', result.data)
-} else {
-  console.error('任务失败')
-}
-```
-
-### 排除初始标签页
-
-默认情况下，Agent 会将初始标签页（运行脚本的页面）包含在任务中。设置 `includeInitialTab: false` 可以排除它：
-
-```typescript
-const result = await window.PAGE_AGENT_EXT!.execute(
-  '打开新标签页并在 GitHub 上搜索 page-agent',
-  {
-    baseURL: 'https://api.openai.com/v1',
-    apiKey: process.env.OPENAI_API_KEY!,
-    model: 'gpt-5.2',
-    includeInitialTab: false,  // Agent 只会打开新标签页
-  }
-)
-```
-
-### 使用事件回调
-
-```typescript
-await window.PAGE_AGENT_EXT!.execute('导航到设置页面', {
-  baseURL: 'https://api.openai.com/v1',
-  apiKey: process.env.OPENAI_API_KEY!,
-  model: 'gpt-5.2',
-  onStatusChange: (status) => {
-    updateUI({ agentStatus: status })
-  },
-  onActivity: (activity) => {
-    switch (activity.type) {
-      case 'thinking':
-        showSpinner('Agent 正在思考...')
-        break
-      case 'executing':
-        showSpinner(`正在执行: ${activity.tool}`)
-        break
-      case 'executed':
-        log(`${activity.tool} 完成，耗时 ${activity.duration}ms`)
-        break
-      case 'error':
-        showError(activity.message)
-        break
-    }
-  },
-  onHistoryUpdate: (history) => {
-    renderHistory(history)
-  },
-})
-```
-
-### 停止执行
-
-```typescript
-// 启动任务
-window.PAGE_AGENT_EXT!.execute('滚动浏览所有页面', {
-  baseURL: 'https://api.openai.com/v1',
-  apiKey: process.env.OPENAI_API_KEY!,
-  model: 'gpt-5.2',
-})
-
-// 稍后停止
-window.PAGE_AGENT_EXT!.dispose()
-```
-
-## Window 类型声明
-
-如果不使用 `@page-agent/core`，可以添加以下声明：
-
-```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
-  onDispose?: () => void
-}
-
-declare global {
-  interface Window {
-    PAGE_AGENT_EXT_VERSION?: string
-    PAGE_AGENT_EXT?: {
-      version: string
-      execute: (task: string, config: ExecuteConfig) => Promise<ExecutionResult>
-      dispose: () => 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
-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>
-```
+2. Add route in `src/pages/docs/index.tsx`
+3. Add navigation item in `src/pages/docs/Layout.tsx`
+4. Add path to `SPA_ROUTES` in `vite.config.js`
 
 ## Configuration Files
