+
+CowAgent 是一個完整的 **Agent Harness**：訊息從各類**通道**進入，**Agent Core** 結合記憶、知識庫與可用工具/技能進行任務規劃與決策，呼叫**模型**生成結果，再回傳至原通道。各模組解耦清晰，按需擴充。
+
+詳見 [專案架構](https://docs.cowagent.ai/zh/intro/architecture)。
+
+<br/>
+
+## 🚀 快速開始
+
+專案提供一鍵安裝指令碼，自動完成依賴安裝、設定和啟動：
+
+**Linux / macOS：**
+
+```bash
+bash <(curl -fsSL https://cdn.link-ai.tech/code/cow/run.sh)
+```
+
+**Windows（PowerShell）：**
+
+```powershell
+irm https://cdn.link-ai.tech/code/cow/run.ps1 | iex
+```
+
+**Docker：**
+
+```bash
+curl -O https://cdn.link-ai.tech/code/cow/docker-compose.yml
+docker compose up -d
+```
+
+啟動成功後開啟 `http://localhost:9899` 進入 **Web 控制台**，在控制台內即可完成模型設定、渠道接入、技能安裝等全部操作。
+
+> 伺服器部署且需要從外部網路存取控制台時，請在 `config.json` 中將 `web_host` 設為 `0.0.0.0`（同時強烈建議設定 `web_password` 啟用身分驗證），然後訪問 `http://<server-ip>:9899`，並確保防火牆/安全組放行 `9899` 埠。

+
+安裝後可使用 `cow` [CLI 命令](https://docs.cowagent.ai/zh/cli) 管理服務：
+
+```bash
+cow start | stop | restart        # 服務管理
+cow status | logs                  # 狀態和日誌
+cow update                         # 拉取最新程式碼並重啟
+cow skill install <名稱>           # 安裝技能
+cow install-browser                # 安裝瀏覽器工具
+```
+

+
+*Web 控制台是預設通道，也是統一的 Agent 設定和管理入口*
+

+
+## 🧠 記憶與知識庫
+
+**長期記憶**採用三層架構：對話上下文（短期）→ 天級記憶（中期）→ MEMORY.md（長期）。每日自動執行**夢境蒸餾（Deep Dream）**，將分散記憶整合為精煉的長期記憶並生成敘事日記。詳見 [長期記憶](https://docs.cowagent.ai/zh/memory) · [夢境蒸餾](https://docs.cowagent.ai/zh/memory/deep-dream)。
+
+**個人知識庫** 與按時間記錄的記憶不同，以**主題為維度**組織結構化知識。Agent 在對話中自動整理有價值資訊，維護交叉引用與索引，Web 控制台可視覺化瀏覽知識圖譜。詳見 [個人知識庫](https://docs.cowagent.ai/zh/knowledge)。

+## 🔧 工具與技能
+
+**工具（Tools）** 是 Agent 作業系統資源的原子能力，**技能（Skills）** 是基於說明檔案的高階工作流，可組合多個工具完成複雜任務。
+
+### 工具系統
+
+**內建工具** 涵蓋檔案讀寫（`read` / `write` / `edit` / `ls`）、終端（`bash`）、檔案傳送（`send`）、記憶檢索（`memory`）、環境變數（`env_config`）、網頁獲取（`web_fetch`）、定時任務（`scheduler`）、聯網搜尋（`web_search`）、影像識別（`vision`）、瀏覽器自動化（`browser`）等常用能力。
+
+**MCP 協議** 透過 [Model Context Protocol](https://modelcontextprotocol.io) 接入開放生態中的各種 MCP 服務，設定一次 `mcp.json` 即用即得，支援 stdio / SSE 協議、熱更新、零程式碼接入。
+
+詳見 [工具概覽](https://docs.cowagent.ai/zh/tools) · [MCP 整合](https://docs.cowagent.ai/zh/tools/mcp)。
+
+### 技能系統
+
+- **[Skill Hub](https://skills.cowagent.ai/)** — 開源的技能廣場，瀏覽、搜尋、一鍵安裝
+- **GitHub / ClawHub / URL 等** — 任意來源一鍵安裝
+- **對話創造** — 透過 `skill-creator` 用對話快速生成自定義技能，可將工作流程或第三方介面直接固化為技能
+
+```bash
+/skill list                   # 檢視當前技能
+/skill search <關鍵詞>         # 在技能廣場搜尋
+/skill install <名稱>          # 一鍵安裝
