n8n Automated Social Media Content Publishing Factory - System Prompt Composition

This n8n workflow acts as an automated factory for generating and publishing social media content. It leverages AI agents to compose system prompts, which can then be used to create diverse content for various platforms. The workflow focuses on the initial prompt composition phase, allowing for human review and conditional routing before content generation and publishing.

Description

This workflow streamlines the process of creating system prompts for AI-driven content generation. It allows for dynamic prompt creation, human-in-the-loop review via Telegram, and conditional routing to different content generation or publishing paths based on the prompt's approval status. This enables a flexible and controlled content creation pipeline.

What it does

  1. Triggers on Chat Message: The workflow starts when a chat message is received, likely initiating the prompt generation process.
  2. Composes System Prompt with AI Agent: An AI Agent is used to generate a system prompt, potentially leveraging a simple memory and a Google Search tool (SerpAPI) for context.
  3. Sends Prompt for Human Review via Telegram: The generated system prompt is sent to a Telegram chat for human review and approval.
  4. Waits for Human Decision: The workflow pauses, waiting for a "yes" or "no" response from the human reviewer in Telegram.
  5. Conditional Routing based on Approval:
    • If Approved (Yes): The workflow proceeds to a "No Operation" node, indicating that the approved prompt is ready for further processing (e.g., content generation, publishing).
    • If Rejected (No): The workflow also proceeds to a "No Operation" node, implying that the rejected prompt might be discarded or sent back for revision.
  6. Merges Paths: Both the approved and rejected paths merge into a single "Merge" node, allowing the workflow to continue or end gracefully.
  7. Optional Content Generation/Publishing (Not Fully Implemented in this JSON): While the JSON shows nodes for Facebook Graph API, X (formerly Twitter), Gmail, LinkedIn, Google Drive, and Google Docs, these are currently isolated and not directly connected to the main prompt composition flow. They represent potential subsequent steps for content publishing or storage once a prompt is approved and content is generated.
  8. Internal Workflow Calls: The workflow includes an "Execute Workflow Trigger" node, suggesting it might be part of a larger, modular system where this workflow composes prompts for other workflows to consume.

Prerequisites/Requirements

  • n8n Instance: A running n8n instance.
  • Telegram Account & Bot: For sending and receiving approval messages.
  • OpenAI API Key: For the OpenAI Chat Model used by the AI Agent.
  • SerpAPI Key: For the SerpAPI (Google Search) tool used by the AI Agent to gather information.
  • Google Drive/Docs Credentials (Optional): If you plan to expand the workflow to store or retrieve content from Google services.
  • Facebook Graph API Credentials (Optional): If you plan to expand the workflow to publish to Facebook.
  • X (formerly Twitter) Credentials (Optional): If you plan to expand the workflow to publish to X.
  • Gmail Credentials (Optional): If you plan to expand the workflow to send emails.
  • LinkedIn Credentials (Optional): If you plan to expand the workflow to publish to LinkedIn.

Setup/Usage

  1. Import the workflow: Download the JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Set up your Telegram Bot credentials.
    • Configure your OpenAI API Key for the "OpenAI Chat Model" node.
    • Set up your SerpAPI Key for the "SerpAPI (Google Search)" node.
    • (Optional) Configure credentials for Google Drive, Google Docs, Facebook Graph API, X, Gmail, and LinkedIn if you intend to extend the workflow for publishing or storage.
  3. Activate the Workflow: Enable the workflow in your n8n instance.
  4. Initiate with a Chat Message: Send a chat message to your configured Telegram bot to trigger the workflow and begin the prompt composition process.
  5. Review in Telegram: Monitor your Telegram chat for the generated system prompt and respond with "yes" or "no" for approval.
  6. Extend the Workflow: Connect the "No Operation, do nothing" nodes (after the "If" node) to your desired content generation and publishing nodes (e.g., Facebook, X, Google Docs) to complete your social media content factory.

Auto-reply & create Linear tickets from Gmail with GPT-5, gotoHuman & human review

This workflow automatically classifies every new email from your linked mailbox, drafts a personalized reply, and creates Linear tickets for bugs or feature requests. It uses a human-in-the-loop with gotoHuman and continuously improves itself by learning from approved examples. How it works The workflow triggers on every new email from your linked mailbox. Self-learning Email Classifier: an AI model categorizes the email into defined categories (e.g., Bug Report, Feature Request, Sales Opportunity, etc.). It fetches previously approved classification examples from gotoHuman to refine decisions. Self-learning Email Writer: the AI drafts a reply to the email. It learns over time by using previously approved replies from gotoHuman, with per-classification context to tailor tone and style (e.g., different style for sales vs. bug reports). Human Review in gotoHuman: review the classification and the drafted reply. Drafts can be edited or retried. Approved values are used to train the self-learning agents. Send approved Reply: the approved response is sent as a reply to the email thread. Create ticket: if the classification is Bug or Feature Request, a ticket is created by another AI agent in Linear. Human Review in gotoHuman: How to set up Most importantly, install the gotoHuman node before importing this template! (Just add the node to a blank canvas before importing) Set up credentials for gotoHuman, OpenAI, your email provider (e.g. Gmail), and Linear. In gotoHuman, select and create the pre-built review template "Support email agent" or import the ID: 6fzuCJlFYJtlu9mGYcVT. Select this template in the gotoHuman node. In the "gotoHuman: Fetch approved examples" http nodes you need to add your formId. It is the ID of the review template that you just created/imported in gotoHuman. Requirements gotoHuman (human supervision, memory for self-learning) OpenAI (classification, drafting) Gmail or your preferred email provider (for email trigger+replies) Linear (ticketing) How to customize Expand or refine the categories used by the classifier. Update the prompt to reflect your own taxonomy. Filter fetched training data from gotoHuman by reviewer so the writer adapts to their personalized tone and preferences. Add more context to the AI email writer (calendar events, FAQs, product docs) to improve reply quality.
