## ⚙️ Valves 配置规范 (Valves Configuration)

使用 Pydantic BaseModel 定义可配置参数：

```python
from pydantic import BaseModel, Field

class Action:
    class Valves(BaseModel):
        SHOW_STATUS: bool = Field(
            default=True,
            description="Whether to show operation status updates."
        )
        MODEL_ID: str = Field(
            default="",
            description="Built-in LLM Model ID. If empty, uses current conversation model."
        )
        MIN_TEXT_LENGTH: int = Field(
            default=50,
            description="Minimum text length required for processing (characters)."
        )
        CLEAR_PREVIOUS_HTML: bool = Field(
            default=False,
            description="Whether to clear previous plugin results."
        )
        MESSAGE_COUNT: int = Field(
            default=1,
            description="Number of recent messages to use for generation."
        )

    def __init__(self):
        self.valves = self.Valves()
```

### 命名规则 (Naming Convention)

- 所有 Valves 字段使用 **大写下划线** (UPPER_SNAKE_CASE)
- 示例：`SHOW_STATUS`, `MODEL_ID`, `MIN_TEXT_LENGTH`

---

## 📤 事件发送规范 (Event Emission)

必须实现以下辅助方法：

```python
async def _emit_status(
    self,
    emitter: Optional[Callable[[Any], Awaitable[None]]],
    description: str,
    done: bool = False,
):
    """Emits a status update event."""
    if self.valves.SHOW_STATUS and emitter:
        await emitter(
            {"type": "status", "data": {"description": description, "done": done}}
        )

async def _emit_notification(
    self,
    emitter: Optional[Callable[[Any], Awaitable[None]]],
    content: str,
    type: str = "info",
):
    """Emits a notification event (info, success, warning, error)."""
    if emitter:
        await emitter(
            {"type": "notification", "data": {"type": type, "content": content}}
        )
```

---

## 📋 日志规范 (Logging Standard)

- **禁止使用** `print()` 语句
- 必须使用 Python 标准库 `logging`

```python
import logging

logging.basicConfig(
    level=logging.INFO, 
    format="%(asctime)s - %(name)s - %(levelname)s - %(message)s"
)
logger = logging.getLogger(__name__)

# 记录关键操作
logger.info(f"Action: {__name__} started")

# 记录异常 (包含堆栈信息)
logger.error(f"Processing failed: {e}", exc_info=True)
```

---

## 🎨 HTML 注入规范 (HTML Injection)

使用统一的标记和结构：

```python
# HTML 包装器标记
HTML_WRAPPER_TEMPLATE = """
<!-- OPENWEBUI_PLUGIN_OUTPUT -->
<!DOCTYPE html>
<html lang="{user_language}">
<head>
    <meta charset="UTF-8">
    <style>
        /* STYLES_INSERTION_POINT */
    </style>
</head>
<body>
    <div id="main-container">
        <!-- CONTENT_INSERTION_POINT -->
    </div>
    <!-- SCRIPTS_INSERTION_POINT -->
</body>
</html>
"""
```

必须实现 HTML 合并方法以支持多次运行插件：

```python
def _remove_existing_html(self, content: str) -> str:
    """Removes existing plugin-generated HTML code blocks."""
    pattern = r"```html\s*<!-- OPENWEBUI_PLUGIN_OUTPUT -->[\s\S]*?```"
    return re.sub(pattern, "", content).strip()

def _merge_html(
    self,
    existing_html: str,
    new_content: str,
    new_styles: str = "",
    new_scripts: str = "",
    user_language: str = "en-US",
) -> str:
    """
    Merges new content into existing HTML container.
    See ACTION_PLUGIN_TEMPLATE.py for full implementation.
    """
    pass  # Implement based on template
```

---

## 🌍 多语言支持 (Internationalization)

从用户上下文获取语言偏好：

```python
def _get_user_context(self, __user__: Optional[Dict[str, Any]]) -> Dict[str, str]:
    """Extracts user context information."""
    if isinstance(__user__, (list, tuple)):
        user_data = __user__[0] if __user__ else {}
    elif isinstance(__user__, dict):
        user_data = __user__
    else:
        user_data = {}

    return {
        "user_id": user_data.get("id", "unknown_user"),
        "user_name": user_data.get("name", "User"),
        "user_language": user_data.get("language", "en-US"),
    }
```

中文版插件默认值：
- `user_language`: `"zh-CN"`
- `user_name`: `"用户"`

英文版插件默认值：
- `user_language`: `"en-US"`
- `user_name`: `"User"`

---

## 📦 依赖管理 (Dependencies)

### requirements 字段规则

- 仅列出 OpenWebUI 环境中**未安装**的依赖
- 使用精确版本号
- 多个依赖用逗号分隔

```python
"""
requirements: python-docx==1.1.2, openpyxl==3.1.2
"""
```

常见 OpenWebUI 已安装依赖（无需在 requirements 中声明）：
- `pydantic`
- `fastapi`
- `logging`
- `re`, `json`, `datetime`, `io`, `base64`

---

## 🔧 代码规范 (Code Style)

### Python 规范

- 遵循 **PEP 8** 规范
- 使用 **Black** 格式化代码
- 关键逻辑添加注释

### 导入顺序

```python
# 1. Standard library imports
import os
import re
import json
import logging
from typing import Optional, Dict, Any, Callable, Awaitable

# 2. Third-party imports
from pydantic import BaseModel, Field
from fastapi import Request

# 3. OpenWebUI imports
from open_webui.utils.chat import generate_chat_completion
from open_webui.models.users import Users
```

---

## 📄 文件导出与命名规范 (File Export and Naming)

对于涉及文件导出的插件（通常是 Action），必须提供灵活的标题生成策略。

### Valves 配置 (Valves Configuration)

应包含 `TITLE_SOURCE` 选项：

```python
class Valves(BaseModel):
    TITLE_SOURCE: str = Field(
        default="chat_title",
        description="Title Source: 'chat_title', 'ai_generated', 'markdown_title'",
    )
```

### 标题获取逻辑 (Title Retrieval Logic)

1.  **chat_title**: 尝试从 `body` 获取，若失败且有 `chat_id`，则从数据库获取 (`Chats.get_chat_by_id`)。
2.  **markdown_title**: 从 Markdown 内容提取第一个 H1 或 H2。
3.  **ai_generated**: 使用轻量级 Prompt 让 AI 生成简短标题。

### 优先级与回退 (Priority and Fallback)

代码应根据 `TITLE_SOURCE` 优先尝试指定方法，若失败则按以下顺序回退：
`chat_title` -> `markdown_title` -> `user_name + date`

```python
# 核心逻辑示例
if self.valves.TITLE_SOURCE == "chat_title":
    title = chat_title
elif self.valves.TITLE_SOURCE == "markdown_title":
    title = self.extract_title(content)
elif self.valves.TITLE_SOURCE == "ai_generated":
    title = await self.generate_title_using_ai(...)
```

### AI 标题生成实现 (AI Title Generation Implementation)

如果支持 `ai_generated` 选项，应实现类似以下的方法：

```python
async def generate_title_using_ai(
    self, 
    body: dict, 
    content: str, 
    user_id: str, 
    request: Any
) -> str:
    """Generates a short title using the current LLM model."""
    if not request:
        return ""

    try:
        # 获取当前用户和模型
        user_obj = Users.get_user_by_id(user_id)
        model = body.get("model")

        # 构造请求
        payload = {
            "model": model,
            "messages": [
                {
                    "role": "system", 
                    "content": "You are a helpful assistant. Generate a short, concise title (max 10 words) for the following text. Do not use quotes. Only output the title."
                },
                {
                    "role": "user", 
                    "content": content[:2000]  # 限制上下文长度以节省 Token
                }
            ],
            "stream": False,
        }

        # 调用 OpenWebUI 内部生成接口
        response = await generate_chat_completion(request, payload, user_obj)
        
        if response and "choices" in response:
            return response["choices"][0]["message"]["content"].strip()
            
    except Exception as e:
        logger.error(f"Error generating title: {e}")

    return ""
```

## 🎭 iframe 主题检测规范 (iframe Theme Detection)

当插件在 iframe 中运行（特别是使用 `srcdoc` 属性）时，需要检测应用程序的主题以保持视觉一致性。

### 检测优先级 (Priority Order)

按以下顺序尝试检测主题，直到找到有效结果：

1. **显式切换** (Explicit Toggle) - 用户手动点击主题按钮
2. **父文档 Meta 标签** (Parent Meta Theme-Color) - 从 `window.parent.document` 的 `<meta name="theme-color">` 读取
3. **父文档 Class/Data-Theme** (Parent HTML/Body Class) - 检查父文档 html/body 的 class 或 data-theme 属性
4. **系统偏好** (System Preference) - `prefers-color-scheme: dark` 媒体查询

### 核心实现代码 (Implementation)

```javascript
// 1. 颜色亮度解析（支持 hex 和 rgb）
const parseColorLuma = (colorStr) => {
    if (!colorStr) return null;
    // hex #rrggbb or rrggbb
    let m = colorStr.match(/^#?([0-9a-f]{6})$/i);
    if (m) {
        const hex = m[1];
        const r = parseInt(hex.slice(0, 2), 16);
        const g = parseInt(hex.slice(2, 4), 16);
        const b = parseInt(hex.slice(4, 6), 16);
        return (0.2126 * r + 0.7152 * g + 0.0722 * b) / 255;
    }
    // rgb(r, g, b) or rgba(r, g, b, a)
    m = colorStr.match(/rgba?\s*\(\s*(\d+)\s*,\s*(\d+)\s*,\s*(\d+)/i);
    if (m) {
        const r = parseInt(m[1], 10);
        const g = parseInt(m[2], 10);
        const b = parseInt(m[3], 10);
        return (0.2126 * r + 0.7152 * g + 0.0722 * b) / 255;
    }
    return null;
};

// 2. 从 meta 标签提取主题
const getThemeFromMeta = (doc, scope = 'self') => {
    const metas = Array.from((doc || document).querySelectorAll('meta[name="theme-color"]'));
    if (!metas.length) return null;
    const color = metas[metas.length - 1].content.trim();
    const luma = parseColorLuma(color);
    if (luma === null) return null;
    return luma < 0.5 ? 'dark' : 'light';
};

// 3. 安全地访问父文档
const getParentDocumentSafe = () => {
    try {
        if (!window.parent || window.parent === window) return null;
        const pDoc = window.parent.document;
        void pDoc.title; // 触发跨域检查
        return pDoc;
    } catch (err) {
        console.log(`Parent document not accessible: ${err.name}`);
        return null;
    }
};

// 4. 从父文档的 class/data-theme 检测主题
const getThemeFromParentClass = () => {
    try {
        if (!window.parent || window.parent === window) return null;
        const pDoc = window.parent.document;
        const html = pDoc.documentElement;
        const body = pDoc.body;
        const htmlClass = html ? html.className : '';
        const bodyClass = body ? body.className : '';
        const htmlDataTheme = html ? html.getAttribute('data-theme') : '';
        
        if (htmlDataTheme === 'dark' || bodyClass.includes('dark') || htmlClass.includes('dark')) 
            return 'dark';
        if (htmlDataTheme === 'light' || bodyClass.includes('light') || htmlClass.includes('light')) 
            return 'light';
        return null;
    } catch (err) {
        return null;
    }
};

// 5. 主题设置及检测
const setTheme = (wrapperEl, explicitTheme) => {
    const parentDoc = getParentDocumentSafe();
    const metaThemeParent = parentDoc ? getThemeFromMeta(parentDoc, 'parent') : null;
    const parentClassTheme = getThemeFromParentClass();
    const prefersDark = window.matchMedia && window.matchMedia('(prefers-color-scheme: dark)').matches;
    
    // 按优先级选择
    const chosen = explicitTheme || metaThemeParent || parentClassTheme || (prefersDark ? 'dark' : 'light');
    wrapperEl.classList.toggle('theme-dark', chosen === 'dark');
    return chosen;
};
```

### CSS 变量定义 (CSS Variables)

使用 CSS 变量实现主题切换，避免硬编码颜色：

```css
:root {
    --primary-color: #1e88e5;
    --background-color: #f4f6f8;
    --text-color: #263238;
    --border-color: #e0e0e0;
}

.theme-dark {
    --primary-color: #64b5f6;
    --background-color: #111827;
    --text-color: #e5e7eb;
    --border-color: #374151;
}

.container {
    background-color: var(--background-color);
    color: var(--text-color);
    border-color: var(--border-color);
}
```

### 调试与日志 (Debugging)

添加详细日志便于排查主题检测问题：

```javascript
console.log(`[plugin] [parent] meta theme-color count: ${metas.length}`);
console.log(`[plugin] [parent] meta theme-color picked: "${color}"`);
console.log(`[plugin] [parent] meta theme-color luma=${luma.toFixed(3)}, inferred=${inferred}`);
console.log(`[plugin] parent html.class="${htmlClass}", data-theme="${htmlDataTheme}"`);
console.log(`[plugin] final chosen theme: ${chosen}`);
```

### 最佳实践 (Best Practices)

- 仅尝试访问**父文档**的主题信息，不依赖 srcdoc iframe 自身的 meta（通常为空）
- 在跨域 iframe 中使用 class/data-theme 作为备选方案
- 使用 try-catch 包裹所有父文档访问，避免跨域异常中断
- 提供用户手动切换主题的按钮作为最高优先级
- 记录详细日志便于用户反馈主题检测问题

### OpenWebUI Configuration Requirement (OpenWebUI Configuration)

For iframe plugins to access parent document theme information, users need to configure:

1. **Enable Artifact Same-Origin Access** - In User Settings: **Interface** → **Artifacts** → Check **iframe Sandbox Allow Same Origin**
2. **Configure Sandbox Attributes** - Ensure iframe's sandbox attribute includes both `allow-same-origin` and `allow-scripts`
3. **Verify Meta Tag** - Ensure OpenWebUI page head contains `<meta name="theme-color" content="#color">` tag

**Important Notes**:
- Same-origin access allows iframe to read theme information via `window.parent.document`
- Cross-origin iframes cannot access parent document and should implement class/data-theme detection as fallback
- Using same-origin access in srcdoc iframe is safe (origin is null, doesn't bypass CORS policy)
- Users can provide manual theme toggle button in plugin as highest priority option
