步骤

1. 创建 Telegram 机器人并获取 token

   在 Telegram 中搜索 @BotFather，按提示创建新机器人，复制获得的 API token。进入 n8n 的 Telegram Trigger 节点，在 Credentials 中选择或新建 telegramApi 凭证，填入该 token。确保机器人有接收消息的权限。

2. 配置 OpenAI 与 Google Sheets 凭证

   在 n8n Credentials 中分别添加：OpenAI API key（openAiApi）；Google Sheets OAuth2 授权（googleSheetsOAuth2Api），按流程完成 Google 账号授权。在 AI Agent 节点（Content collector、Generate LinkedIn Post）的 Language Model 连接中选择已配置的 OpenAI Chat Model。

3. 准备 Google Sheets 并确认列结构

   创建或打开一个 Google Sheets，确保包含以下列：Date、Title、Link、Summary、Insights Commentary。在 Append row in sheet 节点中，选择已授权的 Google 账号，指定 documentId 和 sheetName。模板假设这些列已存在，可自定义增删列。

4. 导入 workflow 并检查节点连接

   从 n8n 模板库导入 workflow（或粘贴 workflow JSON）。检查主链路：Telegram Trigger → article or generate?（IF 分支）→ Set Field → Content collector → Edit Fields → Clean Code → Append row in sheet → Send a text message。'generate' 分支：If generate → Generate LinkedIn Post → The post。确认 OpenAI Chat Model 已连接到两个 AI Agent 节点的 ai_languageModel 接口；Get row(s) in sheet in Google Sheets 已连接到 Generate LinkedIn Post 的 ai_tool 接口。

5. 自定义 AI 提示词（关键：替换品牌与风格）

   进入 Content collector 节点的 options.systemMessage，将其中 'Demandbox' 示例替换为自己的品牌或身份，调整 ROLE、CAPABILITIES、INPUT HANDLING 中的领域关键词（当前聚焦 AI automations、operations、technology）。进入 Generate LinkedIn Post 节点的 options.systemMessage，同样替换 'Demandbox' 示例，调整 voice、length、CTA、hashtags 以匹配个人风格。两个节点的 user prompt 分别保持默认即可，也可按需修改。
