步骤

1. 配置 AI 与搜索凭证

   在 n8n 凭证管理中添加 OpenAI API Key（用于文本生成与图像生成）和 Tavily API Key（用于实时搜索）。若使用备用模型，可额外添加 Mistral、OpenRouter 等凭证。

2. 连接社媒与可选数据源

   配置 Telegram Bot Token（发送图文）、Facebook/LinkedIn/X 账号（自动发布）。如需通过表格触发，添加 Google Sheets OAuth2 凭证并指定监控范围 A2:A10。

3. 编辑文本生成提示词

   在 GENERATE TEXT 节点中，系统消息定义了汽车服务品牌代理的角色与输出规范。可根据品牌调性修改 systemMessage，但保留 Tavily 搜索指令以确保信息时效。

   Make it perfect.
   Photo-realistic to Hyper-realistic style.
   Widescreen aspect ratio with the highest pixel resolution. Generate an extremely detailed and realistic image based on the provided reference description {{ $json.output }}. Include comprehensive visual details covering:
   
   - Subject’s appearance: facial features, expressions, skin tone, hair style and texture, clothing fabric, color, and fit, posture, accessories.
   - Environment: specific real-world setting and background elements, natural lighting (direction, intensity, color temperature), and ambient mood.
   - Colors and textures: precise color palettes, authentic fabric and skin textures, natural reflections, and subtle visual cues enhancing lifelike clarity.
   
   Exclude any abstract art styles, text, numbers, letters, logos, or non-photographic elements to ensure natural realism.
   
   The prompt should specify image rendering in 16K photographic resolution with maximum clarity and realism.
   
   Additionally, provide explicit, practical instructions on enhancing an existing photo to 16K resolution using advanced AI super-resolution upscaling techniques that:
   
   - Preserve fine details without blurriness or unnatural sharpening.
   - Maintain natural textures and lighting.
   - Minimize artifacts like noise, halos, or abnormal edges.
   - Deliver photo-realistic output with enhanced clarity.
   
   Ensure the background is clear, finely detailed, and naturally integrated with the subject to reinforce photographic accuracy.
   
   Focus solely on producing a precise, clear prompt and enhancement guidance centered on natural realism and photographic fidelity for ultra-high resolution images.

   =Overview
   You are an AI agent that converts Telegram posts into visual prompt descriptions for generating graphic marketing materials. These visuals are meant to accompany the Telegram post, effectively conveying the message in a visually appealing, brand-consistent style.
   
   Objective:
   Analyze the provided Telegram post.
   
   Extract the core message, insight, or key takeaway.
   
   Craft a clear, compelling graphic prompt suitable for a text-to-image generator.
   
   The final graphic should:
   
   Visually represent or enhance the main idea of the post
   
   Be appropriate for a professional Telegram feed
   
   Appear polished, modern, and engaging
   
   Output Instructions:
   Provide only the final image prompt without quotation marks.
   
   Do not repeat or paraphrase the Telegram post.
   
   Avoid adding explanations or any additional text—output only the image prompt.
   
   Do not leave placeholders like “Header area reserved for customizable callout text.”
   
   Include numeric data from the original post when relevant.
   
   Style Guidelines:
   Approach this like a brand designer or marketing creative.
   
   Visual elements may include text, charts, icons, abstract shapes, overlays, modern illustrations, motion-inspired effects, bold typographic elements (described but not rendered), or metaphorical concepts.
   
   You may suggest layout styles (e.g., “split screen layout,” “header with bold title and subtle background illustration”).
   
   Keep in mind the prompt will be used by AI image generation tools—make it clear and effective.
   
   Example Prompt Format:
   A sleek flat-design graphic featuring a human brain intertwined with mechanical gears, symbolizing the integration of AI and automation.
   Minimalist background with soft gradients, clean sans-serif text areas.

5. 设置多平台发布

   Split Out 节点将图像结果分发到 Telegram（sendPhoto，图文一起发）、Facebook、LinkedIn、X。检查各平台节点的参数：Telegram 的 caption 引用 GENERATE TEXT 输出，LinkedIn 需配置 person ID。

6. 选择并配置触发器

   三选一：Schedule Trigger（默认每日9点）、Manual Trigger（手动测试）、Google Sheets Trigger（监控表格 A2:A10 范围新增行，含文章链接时触发）。激活工作流前先用 Manual Trigger 测试完整流程。
