Creating high-quality technical content at scale is expensive and time-consuming. Manual article writing takes 3-5 hours per piece, and maintaining consistency across multiple writers is nearly impossible. This n8n workflow solves that problem by automating the entire process—from job posting input to publication-ready SEO article output—using Claude AI's advanced language capabilities.
You'll learn how to build an AI agent that takes job postings, demo scripts, and n8n workflow JSONs as inputs, then generates comprehensive technical articles following a strict editorial structure. The complete n8n workflow JSON template is available at the bottom of this article.
The Problem: Manual Technical Writing Doesn't Scale
Technical content creation faces three critical bottlenecks that prevent businesses from scaling their content operations effectively.
Current challenges:
- Writers spend 3-5 hours per article researching, structuring, and writing technical content
- Maintaining consistent tone, structure, and technical accuracy across multiple writers is nearly impossible
- Subject matter experts lack time to document their knowledge in educational formats
- Content agencies charge $500-2000 per technical article with 2-week turnaround times
Business impact:
- Time spent: 15-25 hours per week for a 5-article content calendar
- Cost: $2,500-10,000 monthly for outsourced technical writing
- Opportunity cost: Technical experts spending time writing instead of building
Manual processes also struggle with citation-worthy content. Articles need tables, specific technical details, and structured information that AI can retrieve—but human writers often skip these elements under deadline pressure.
The Solution Overview
This n8n workflow creates an AI-powered content generation system that converts raw technical inputs into publication-ready articles. The agent uses Claude 3.5 Sonnet with a 200,000 token context window to process job postings, n8n workflow JSONs, and demo scripts simultaneously.
The system implements a structured prompt that enforces editorial standards, ensuring every article follows a consistent 14-section format with tables, code blocks, and technical specifications. The workflow outputs clean markdown with frontmatter, ready for immediate publication in static site generators or CMS platforms.
What You'll Build
This workflow automates the complete article creation pipeline with specific capabilities designed for technical content at scale.
| Component | Technology | Purpose |
|---|---|---|
| Input Processing | Manual Trigger Node | Accepts job posting, workflow JSON, and demo script |
| AI Generation | Claude AI (Anthropic) | Generates 1,200-word structured articles |
| Prompt Engineering | System Prompt (200K tokens) | Enforces 14-section editorial structure |
| Output Formatting | Markdown with Frontmatter | Publication-ready content with SEO metadata |
| Quality Control | JSON Schema Validation | Ensures consistent article structure |
Key capabilities:
- Processes multiple input types: job descriptions, technical workflows, and video scripts
- Generates articles with exact technical specifications from n8n workflow JSON
- Creates citation-worthy content with tables, code blocks, and structured data
- Maintains authoritative tone with short sentences and active voice
- Outputs SEO-optimized content with title and meta description
- Includes 14 required H2 sections for comprehensive coverage
- Produces 1,200-word articles in 30-45 seconds
Prerequisites
Before starting, ensure you have:
- n8n instance (cloud or self-hosted version 1.0+)
- Anthropic API account with Claude access
- API key with sufficient credits ($5 minimum recommended)
- Basic understanding of prompt engineering concepts
- Text editor for customizing the system prompt
- Markdown preview tool for reviewing output
Technical requirements:
- n8n version 1.0 or higher (for updated AI nodes)
- Anthropic API access to Claude 3.5 Sonnet model
- Minimum 200,000 token context window support
Step 1: Set Up the Manual Trigger and Input Structure
The workflow begins with a Manual Trigger node that accepts three distinct text inputs: the job posting, n8n workflow JSON, and demo script or voiceover.
Configure the Manual Trigger node:
- Add a Manual Trigger node to your canvas
- This node requires no configuration—it simply initiates the workflow
- The trigger will accept data passed from the execution panel
Input structure:
The workflow expects three text fields in the execution:
job_posting: The complete job description or project requirementsworkflow_json: The full n8n workflow JSON exportdemo_script: Video voiceover or demonstration walkthrough text
Why this works:
Manual triggers give you complete control over when articles generate. You can batch multiple job postings, test different prompt variations, or integrate this workflow into larger automation sequences. The three-input structure ensures the AI has complete context—the business problem (job posting), the technical solution (workflow JSON), and the user experience (demo script).
Step 2: Build the System Prompt with Editorial Structure
The Claude AI node uses a comprehensive system prompt that enforces the entire editorial structure. This prompt is the workflow's intelligence—it defines tone, format, and content requirements.
Configure the Claude AI node:
- Add an "OpenAI Model" node (works with Anthropic API)
- Select "Claude 3.5 Sonnet" as the model
- Set max tokens to 200,000 for full context window
- Temperature: 0.3 (lower for consistency, higher for creativity)
System prompt structure:
You are an expert technical writer specializing in workflow automation and n8n implementations. Your task is to convert n8n Upwork job postings and demo videos into comprehensive, educational articles that teach readers how to build the solution themselves.
## Writing Principles
Tone & Style:
- Authoritative and confident
- Educational, not promotional
- Short, punchy sentences
- Active voice, addressing the reader directly ("you")
- Technical precision without jargon overload
The prompt continues with 14 required H2 sections, each with specific formatting requirements, content guidelines, and example structures.
Critical prompt components:
- Token budget:
<budget:token_budget>200000</budget:token_budget>ensures full context usage - Output format: JSON object with title, meta_description, and body fields
- Section templates: Each H2 includes exact formatting with tables, code blocks, or checklists
- Content guidelines: Explicit "Do" and "Don't" lists prevent generic content
Why this approach:
System prompts act as persistent instructions that shape every response. By encoding the entire editorial structure in the prompt, you eliminate the need for post-processing or manual editing. The AI becomes a specialized technical writer that follows your exact style guide.
Variables to customize:
target_length: Adjust from 1,200 words for different content depthstemperature: Lower (0.1-0.3) for technical accuracy, higher (0.5-0.7) for creative variationssection_requirements: Add or remove H2 sections based on your content needs
Step 3: Process Inputs and Generate Articles
The Claude AI node receives the three inputs and system prompt, then generates the complete article in a single API call.
Node configuration:
{
"model": "claude-3-5-sonnet-20241022",
"maxTokens": 200000,
"options": {
"temperature": 0.3,
"topP": 1
},
"messages": [
{
"role": "user",
"content": "Create a comprehensive technical article teaching how to build this n8n agent.
## Job Posting
**Title:** {{ $json.job_posting_title }}
**Description:** {{ $json.job_posting }}
## N8N Workflow JSON
{{ $json.workflow_json }}
## Demo Script/Voiceover
{{ $json.demo_script }}"
}
]
}
Execution flow:
- Manual trigger fires with three text inputs
- Claude AI node receives inputs via n8n expressions
- System prompt enforces 14-section structure
- AI processes all context (job + JSON + script) simultaneously
- Output returns as JSON with title, meta_description, and body
- Average processing time: 30-45 seconds
Why this works:
Claude's 200,000 token context window can process the entire job posting, a complex n8n workflow JSON (often 5,000-15,000 tokens), and a demo script simultaneously. This holistic context ensures the article accurately describes the technical implementation while matching the business language from the job posting.
The single API call approach is more reliable than multi-step generation. You avoid context loss between steps and ensure the article maintains consistent tone throughout all 14 sections.
Workflow Architecture Overview
This workflow consists of 2 nodes organized into a simple linear flow:
- Input collection (Node 1): Manual trigger accepts three text fields
- AI generation (Node 2): Claude processes inputs and generates article
Execution flow:
- Trigger: Manual execution from n8n interface
- Average run time: 30-45 seconds depending on input length
- Key dependencies: Anthropic API credentials configured in n8n
Critical nodes:
- Manual Trigger: Provides flexible input method for batch processing
- Claude AI (OpenAI Model node): Handles entire article generation with 200K token context
- System Prompt: Embedded in AI node, enforces all editorial standards
The workflow's simplicity is intentional. By consolidating all logic into the system prompt, you avoid complex branching, data transformation, or post-processing nodes. The complete n8n workflow JSON template is available at the bottom of this article.
Key Configuration Details
The Claude AI node requires specific settings to generate high-quality technical content consistently.
Anthropic API Integration
Required fields:
- API Key: Your Anthropic API key from console.anthropic.com
- Model:
claude-3-5-sonnet-20241022(latest version) - Max Tokens: 200,000 (full context window)
- Temperature: 0.3 (balance between creativity and consistency)
Common issues:
- Using older Claude models → Results in shorter context windows (100K tokens)
- Temperature above 0.5 → Produces inconsistent article structures
- Max tokens below 100,000 → Truncates long workflow JSONs in context
System prompt customization:
The system prompt lives in the "System Message" field of the OpenAI Model node. Key sections to customize:
<budget:token_budget>200000</budget:token_budget>
This XML tag tells Claude to use its full context window. Without it, the model may truncate long inputs.
Output format enforcement:
The prompt explicitly requires JSON output:
Return ONLY the JSON object. Do not include:
- Any explanations before or after
- Any meta-commentary
- Any instructions
This prevents the AI from adding conversational text around the article, ensuring clean output for automated publishing.
Why this approach:
Embedding all editorial logic in the system prompt creates a self-contained article generator. You can modify tone, structure, or requirements by editing the prompt—no workflow changes needed. This separation of concerns makes the system maintainable and scalable.
Testing & Validation
Test the workflow with progressively complex inputs to verify output quality and consistency.
Test sequence:
- Simple test: Use a short job posting (2-3 paragraphs), minimal workflow JSON (10-20 nodes), and brief demo script
- Review output structure: Verify all 14 H2 sections appear with correct formatting
- Check technical accuracy: Compare workflow JSON details against article descriptions
- Validate tables: Ensure tables render correctly with proper markdown syntax
- Test edge cases: Very long workflow JSONs (10,000+ tokens), missing demo scripts, vague job postings
Common issues and fixes:
| Issue | Cause | Solution |
|---|---|---|
| Missing H2 sections | Temperature too high | Reduce to 0.2-0.3 |
| Generic content | Insufficient input context | Add more detail to job posting and demo script |
| Truncated output | Max tokens too low | Increase to 200,000 |
| Inconsistent tone | System prompt not specific enough | Add more "Do/Don't" examples |
Quality checklist:
- Article includes all 14 required H2 sections
- Tables format correctly in markdown preview
- Code blocks use proper syntax highlighting
- Technical details match workflow JSON exactly
- Tone remains authoritative and educational throughout
- Meta description under 155 characters
- Article length approximately 1,200 words
Deployment Considerations
Moving this workflow to production requires attention to API costs, error handling, and content review processes.
Production Deployment Checklist
| Area | Requirement | Why It Matters |
|---|---|---|
| API Costs | Monitor token usage per article | Claude charges per input/output token; 1,200-word articles cost $0.50-2.00 |
| Error Handling | Add Error Trigger node after Claude AI | Catches API failures, rate limits, or malformed outputs |
| Content Review | Manual approval step before publishing | AI-generated content needs human verification for brand voice |
| Version Control | Save system prompt in Git | Track prompt iterations and their impact on output quality |
| Rate Limiting | Add Wait node for batch processing | Anthropic enforces rate limits; space out multiple executions |
Monitoring recommendations:
Set up n8n's built-in execution logging to track:
- Average token usage per article (input + output)
- API failure rates and error types
- Generation time trends (watch for slowdowns)
- Output length consistency (should stay near 1,200 words)
Error handling strategy:
Add an Error Trigger node connected to the Claude AI node:
{
"errorWorkflow": "notify-admin-on-failure",
"continueOnFail": false,
"retryOnFail": true,
"maxTries": 3,
"waitBetweenTries": 5000
}
This configuration retries failed API calls three times with 5-second delays, then triggers an admin notification workflow if all attempts fail.
