+"""
+Slack channel via Bolt for Python (Socket Mode).
+
+Features:
+- Direct message & channel chat (text / image / file)
+- Channel trigger: @mention or reply in a thread the bot is in (configurable)
+- /cancel fast-path matches Web channel behaviour
+- Socket Mode: no public IP / callback URL required, works behind NAT
+
+Implementation note:
+    slack_bolt's SocketModeHandler is blocking and runs its own background
+    threads. We start it in a dedicated thread so the rest of cow (sync) stays
+    untouched. Inbound events are dispatched onto cow's existing sync
+    ChatChannel.produce() pipeline; outbound send() calls the Slack Web API
+    client directly (it is sync-safe).

+title: Slack
+description: 将 CowAgent 接入 Slack App
+---
+
+> 通过 Slack App 的 **Socket Mode** 接入 CowAgent，支持私聊（DM）与频道（@机器人 / 线程内回复触发）。Socket Mode 基于长连接，无需公网 IP 与回调地址，开箱即用。
+
+## 一、接入步骤
+
+### 步骤一：创建 Slack App
+
+1. 打开 [Slack API 应用管理页](https://api.slack.com/apps)，点击 **Create New App** → **From scratch**。
+2. 填写 **App Name**（如 `CowAgent`），选择要安装的 **Workspace**，点击创建。
+
+### 步骤二：开启 Socket Mode 并获取 App Token
+
+1. 左侧菜单进入 **Settings → Socket Mode**，打开 **Enable Socket Mode**。
+2. 系统会提示生成一个 **App-Level Token**，作用域勾选 `connections:write`，生成后保存这串以 `xapp-` 开头的 Token。
+
+<Tip>
+  Socket Mode 通过 WebSocket 长连接接收事件，无需在公网暴露回调 URL，适合本地或内网部署。
+</Tip>
+
+### 步骤三：配置 Bot 权限并安装
+
+1. 进入 **Features → OAuth & Permissions**，在 **Bot Token Scopes** 中点击 **Add an OAuth Scope**，逐项添加以下权限：
+
+   ```
+   app_mentions:read
+   channels:history
+   chat:write
+   commands
+   files:read
+   files:write
+   groups:history
+   im:history
+   mpim:history
+   users:read
+   ```
+
+   <Note>
+     `files:read` / `files:write` 用于图片、文件的收发；若仅需文本对话可省略。
+   </Note>
+
+2. 进入 **Features → Event Subscriptions**，打开 **Enable Events**，在 **Subscribe to bot events** 中点击 **Add Bot User Event** 添加以下事件：
+
+   ```
+   app_mention
+   message.im
+   message.channels
+   ```
+
+   <Note>
+     如需在私有频道使用，再添加 `message.groups`。
+   </Note>
+3. 进入 **Features → App Home**，在 **Show Tabs** 区域勾选 **Messages Tab**，并勾选下方的 **Allow users to send Slash commands and messages from the messages tab**（允许用户从消息标签页发送消息），否则私聊输入框会被关闭、无法给机器人发消息。
+4. 回到 **OAuth & Permissions**，点击 **Install to Workspace** 完成安装，安装后获取以 `xoxb-` 开头的 **Bot User OAuth Token**。
+
+<Tip>
+  若 Slack 客户端仍提示「向此应用发送消息的功能已关闭」，请确认已完成上一步的 App Home 设置，并刷新或重启 Slack 客户端（必要时把 App 从对话列表移除后重新打开）。
+</Tip>
+
+### 步骤四：接入 CowAgent
+
+<Tabs>
+  <Tab title="Web 控制台（推荐）">
+    打开 Web 控制台（本地链接：http://127.0.0.1:9899 ），选择 **通道** 菜单，点击 **接入通道**，选择 **Slack**，分别填入 Bot Token（`xoxb-`）和 App Token（`xapp-`），点击接入即可。
+  </Tab>
+  <Tab title="配置文件">
+    在 `config.json` 中添加以下配置后启动：
+
+    ```json
+    {
+      "channel_type": "slack",
+      "slack_bot_token": "xoxb-xxxxxxxxxxxx",
+      "slack_app_token": "xapp-xxxxxxxxxxxx",
+      "slack_group_trigger": "mention_or_reply"
+    }
+    ```
+
+    | 参数 | 说明 | 默认值 |
+    | --- | --- | --- |
+    | `slack_bot_token` | Bot User OAuth Token，形如 `xoxb-...` | - |
+    | `slack_app_token` | App-Level Token（开启 Socket Mode 后生成），形如 `xapp-...` | - |
+    | `slack_group_trigger` | 频道触发方式：`mention_or_reply`（@或线程内回复）/ `mention_only`（仅@） / `all`（所有消息） | `mention_or_reply` |
+  </Tab>
+</Tabs>
+
+启动 Cow 后，日志中出现以下输出即表示接入成功：
+
+```
+[Slack] Bot logged in as user_id=U0XXXXXXX, team=Txxxxxxxx
+[Slack] ✅ Slack bot ready, listening for events
+```
+
+## 二、功能说明
+
+| 功能 | 支持情况 |
+| --- | --- |
+| 私聊（DM） | ✅ |
+| 频道（@机器人 / 线程内回复） | ✅ |
+| 文本消息 | ✅ 收发 |
+| 图片消息 | ✅ 收发 |
+| 文件消息 | ✅ 收发（PDF / Word / Excel 等） |
+| 线程回复 | ✅ 回复发送至触发消息所在线程 |
+
+<Note>
+  Slack 通过线程（Thread）组织对话。机器人会把回复发送到触发消息所在的线程，频道内更整洁。
+</Note>
+
+## 三、使用
+
+完成接入后：
+
+- **私聊（DM）**：在 Slack 左侧 **Apps** 中找到你的 App，直接发消息对话。
+- **频道**：把 App 邀请进频道（`/invite @你的App`），使用 `@你的App 你好` 触发对话；后续在同一线程内直接回复即可继续对话。
+
+发送图片或文件时，可以在附件的输入框中 **添加文字说明**（描述/问题）一并发送，机器人会结合附件回答。也支持先发附件再发问题，两条消息会自动合并提问。

+title: Slack
+description: Integrate CowAgent with a Slack App
+---
+
+> Integrate CowAgent into Slack via a Slack App in **Socket Mode**. Supports direct messages (DM) and channels (triggered by @mention or replying within a thread). Socket Mode uses a persistent WebSocket connection — no public IP or callback URL required, works out of the box.
+
+## 1. Setup
+
+### Step 1: Create a Slack App
+
+1. Open the [Slack API apps page](https://api.slack.com/apps), click **Create New App** → **From scratch**.
+2. Enter an **App Name** (e.g. `CowAgent`), pick the **Workspace** to install into, and create it.
+
+### Step 2: Enable Socket Mode and get the App Token
+
+1. In the left sidebar go to **Settings → Socket Mode** and turn on **Enable Socket Mode**.
+2. You will be prompted to generate an **App-Level Token** with the `connections:write` scope. Save this token starting with `xapp-`.
+
+<Tip>
+  Socket Mode receives events over a WebSocket connection, so you don't need to expose a public callback URL — ideal for local or intranet deployments.
+</Tip>
+
+### Step 3: Configure bot scopes and install
+
+1. Go to **Features → OAuth & Permissions**, click **Add an OAuth Scope** under **Bot Token Scopes**, and add the following scopes one by one:
+
+   ```
+   app_mentions:read
+   channels:history
+   chat:write
+   commands
+   files:read
+   files:write
+   groups:history
+   im:history
+   mpim:history
+   users:read
+   ```
+
+   <Note>
+     `files:read` / `files:write` are used for sending/receiving images and files; omit them if you only need text conversations.
+   </Note>
+
+2. Go to **Features → Event Subscriptions**, turn on **Enable Events**, and under **Subscribe to bot events** click **Add Bot User Event** to add:
+
+   ```
+   app_mention
+   message.im
+   message.channels
+   ```
+
+   <Note>
+     Add `message.groups` if you need to use the bot in private channels.
+   </Note>
+3. Go to **Features → App Home**, enable **Messages Tab** under **Show Tabs**, and check **Allow users to send Slash commands and messages from the messages tab**. Otherwise the DM input box is disabled and users cannot message the bot.
+4. Back in **OAuth & Permissions**, click **Install to Workspace**. After installing, copy the **Bot User OAuth Token** starting with `xoxb-`.
+
+<Tip>
+  If the Slack client still shows "Sending messages to this app has been turned off", make sure you completed the App Home step above, then refresh or restart the Slack client (remove the app from your conversations and reopen it if needed).
+</Tip>
+
+### Step 4: Connect to CowAgent
+
+<Tabs>
+  <Tab title="Web Console (Recommended)">
+    Open the Web Console (default `http://127.0.0.1:9899`), go to **Channels**, click **Add Channel**, choose **Slack**, paste the Bot Token (`xoxb-`) and App Token (`xapp-`), and click connect.
+  </Tab>
+  <Tab title="Config File">
+    Add the following to `config.json` and start Cow:
+
+    ```json
+    {
+      "channel_type": "slack",
+      "slack_bot_token": "xoxb-xxxxxxxxxxxx",
+      "slack_app_token": "xapp-xxxxxxxxxxxx",
+      "slack_group_trigger": "mention_or_reply"
+    }
+    ```
+
+    | Key | Description | Default |
+    | --- | --- | --- |
+    | `slack_bot_token` | Bot User OAuth Token, like `xoxb-...` | - |
+    | `slack_app_token` | App-Level Token (generated after enabling Socket Mode), like `xapp-...` | - |
+    | `slack_group_trigger` | Channel trigger: `mention_or_reply` (@ or reply in thread) / `mention_only` (@ only) / `all` (all messages) | `mention_or_reply` |
+  </Tab>
+</Tabs>
+
+The integration is ready when you see logs like:
+
+```
+[Slack] Bot logged in as user_id=U0XXXXXXX, team=Txxxxxxxx
+[Slack] ✅ Slack bot ready, listening for events
+```
+
+## 2. Capabilities
+
+| Feature | Support |
+| --- | --- |
+| Direct message (DM) | ✅ |
+| Channel (@bot / reply in thread) | ✅ |
+| Text messages | ✅ send / receive |
+| Image messages | ✅ send / receive |
+| File messages | ✅ send / receive (PDF / Word / Excel, etc.) |
+| Thread replies | ✅ replies are posted to the thread of the triggering message |
+
+<Note>
+  Slack organizes conversations into threads. The bot posts replies into the thread of the triggering message, keeping channels tidy.
+</Note>
+
+## 3. Usage
+
+Once connected:
+
+- **Direct message (DM)**: find your App under **Apps** in the Slack sidebar and message it directly.
+- **Channel**: invite the App into a channel (`/invite @your-app`), then trigger it with `@your-app hello`; continue the conversation by replying within the same thread.
+
+When sending an image or file, you can **add a text caption** (description / question) in the attachment input — the bot will answer based on both. Sending an attachment first and then a follow-up question also works; the two messages are merged automatically.

+title: Slack
+description: Slack App 経由で CowAgent を接続
+---
+
+> Slack App の **Socket Mode** を通じて CowAgent を接続します。ダイレクトメッセージ（DM）およびチャンネル（@メンションまたはスレッド内の返信で起動）に対応。Socket Mode は WebSocket の常時接続を使うため公開 IP やコールバック URL は不要で、すぐに利用できます。
+
+## 1. 接続手順
+
+### ステップ 1: Slack App を作成
+
+1. [Slack API アプリ管理ページ](https://api.slack.com/apps) を開き、**Create New App** → **From scratch** をクリックします。
+2. **App Name**（例: `CowAgent`）を入力し、インストール先の **Workspace** を選択して作成します。
+
+### ステップ 2: Socket Mode を有効化し App Token を取得
+
+1. 左メニューの **Settings → Socket Mode** で **Enable Socket Mode** をオンにします。
+2. `connections:write` スコープを持つ **App-Level Token** の生成を求められます。`xapp-` で始まるこの Token を保存してください。
+
+<Tip>
+  Socket Mode は WebSocket 接続でイベントを受信するため、公開コールバック URL を公開する必要がありません。ローカルやイントラネットでの運用に最適です。
+</Tip>
+
+### ステップ 3: Bot 権限を設定してインストール
+
+1. **Features → OAuth & Permissions** を開き、**Bot Token Scopes** で **Add an OAuth Scope** をクリックして以下を 1 つずつ追加します:
+
+   ```
+   app_mentions:read
+   channels:history
+   chat:write
+   commands
+   files:read
+   files:write
+   groups:history
+   im:history
+   mpim:history
+   users:read
+   ```
+
+   <Note>
+     `files:read` / `files:write` は画像・ファイルの送受信に使用します。テキスト会話のみであれば省略可能です。
+   </Note>
+
+2. **Features → Event Subscriptions** を開き、**Enable Events** をオンにして、**Subscribe to bot events** で **Add Bot User Event** をクリックし、以下を追加します:
+
+   ```
+   app_mention
+   message.im
+   message.channels
+   ```
+
+   <Note>
+     非公開チャンネルで使用する場合は `message.groups` も追加してください。
+   </Note>
+3. **Features → App Home** を開き、**Show Tabs** 内の **Messages Tab** を有効にして、下の **Allow users to send Slash commands and messages from the messages tab**（メッセージタブからの送信を許可）にチェックを入れます。これを行わないと DM の入力欄が無効化され、ボットにメッセージを送れません。
+4. **OAuth & Permissions** に戻り、**Install to Workspace** をクリックしてインストールします。インストール後、`xoxb-` で始まる **Bot User OAuth Token** を取得します。
+
+<Tip>
+  Slack クライアントで「このアプリへのメッセージ送信は無効です」と表示される場合は、上記の App Home 設定が完了しているか確認し、Slack クライアントを再読み込み／再起動してください（必要に応じてアプリを会話一覧から削除して再度開きます）。
+</Tip>
+
+### ステップ 4: CowAgent に接続
+
+<Tabs>
+  <Tab title="Web コンソール（推奨）">
+    Web コンソール（既定 `http://127.0.0.1:9899`）を開き、**チャネル** メニュー → **チャネルを追加** → **Slack** を選択し、Bot Token（`xoxb-`）と App Token（`xapp-`）を貼り付けて接続をクリックします。

+  </Tab>
+</Tabs>
+
+ログに以下のような出力が表示されれば接続成功です:
+
+```
+[Slack] Bot logged in as user_id=U0XXXXXXX, team=Txxxxxxxx
+[Slack] ✅ Slack bot ready, listening for events
+```
+
+## 2. 機能
+
+| 機能 | 対応状況 |
+| --- | --- |
+| ダイレクトメッセージ（DM） | ✅ |
+| チャンネル（@bot / スレッド返信） | ✅ |
+| テキストメッセージ | ✅ 送受信 |
+| 画像メッセージ | ✅ 送受信 |
+| ファイルメッセージ | ✅ 送受信（PDF / Word / Excel など） |

+
+## 3. 使い方
+
+接続が完了したら:
+
+- **ダイレクトメッセージ（DM）**: Slack の左サイドバー **Apps** からアプリを開き、直接メッセージを送ります。
+- **チャンネル**: アプリをチャンネルに招待し（`/invite @your-app`）、`@your-app こんにちは` で起動します。以降は同じスレッド内で返信すれば会話を継続できます。
+
+画像やファイルを送るときは、添付の入力欄に **テキスト説明**（説明・質問）を書いて一緒に送信できます。Bot は添付ファイルと説明を合わせて回答します。先に添付を送り、その後に質問を送る形でも、2 つのメッセージは自動でまとめて処理されます。
