Why Use Claude/ChatGPT to Build Prompts?

Writing system prompts manually often results in a lack of detail. AI like Claude can automatically add critical elements such as personality, communication guidelines, and error handling, making your agent significantly more stable.

Plain Language First Tip

Don't stress over formal prompt structures at the start. Focus on 'what the agent needs to do' in everyday language, then let a more powerful LLM handle the technical structuring.

Baseline Agent Description

Target: Claude
Here's what I want my Santa's helper agent to do. It will receive some details from a kid about their interests. It's then going to use its find toys tool to find the top three relevant toys. The kid will then give feedback about those toys, whether they're good or whether more should be suggested. And finally, it should use its send wish list tool to send the wish list of the kid to the parent or whoever is shopping for Christmas.
Step by Step

How to Generate a Professional System Prompt Using Claude

  1. Open the AI Agent editor in N8N or your preferred platform.
  2. Click on the agent's name to change it to something more specific (e.g., 'Santa's Helper AI Agent') for easier reference.
  3. Locate the 'System Instruction' or 'System Prompt' section within the AI Agent configuration.
  4. Avoid writing complex system messages manually directly into that box.
  5. Draft your agent's objective in plain language first. Include: the agent's role, the inputs it will receive, the tools it needs to use, and the desired final output.
  6. Copy that plain language text.
  7. Open your preferred AI Chat tool (Claude, ChatGPT, or Gemini).
  8. Paste your description and instruct the AI to transform it into a 'detailed system prompt'.
  9. Review the AI-generated output to ensure it covers: Role & Personality, Core Workflow (Step-by-step), Tool Instructions, Communication Guidelines, and Error Handling.
  10. Copy the resulting system prompt generated by the AI.
  11. Return to your AI Agent platform (like N8N) and paste the full prompt into the 'System Message' or 'System Prompt' field.
  12. Click 'Save' or save your changes before starting the testing phase.
