# Improve AI agent system prompts with GPT-4o and receive optimized version by email
This automation helps developers and teams working with AI agents to quickly optimize system prompts based on real behavior and user feedback. A simple form captures input, which is then processed by a LangChain agent using GPT-4o to generate an improved prompt, delivered directly to email in a structured format.
## Who it´s for
- AI agent developers who regularly tune system prompts.
- ML engineers analyzing and adjusting agent behavior.
- Teams automating AI improvement through feedback loops.
- Product managers of AI systems using manual tuning phases.
## What the automation does
- User submits agent details and performance feedback via a form.
- Data is sent via HTTP webhook to n8n.
- A LangChain agent powered by GPT-4o analyzes the current prompt and generates an optimized version.
- Output is structured using JSON Schema Parser.
- Result is sent via email (Gmail) as an HTML message with clear side-by-side comparison of old and new prompts.
## What´s included
- Ready-to-use n8n workflow.
- Trigger logic for form_submit via webhook.
- Integrations with OpenAI API and Gmail.
- Basic text instructions for setup and adaptation.
## Requirements for setup
- n8n instance (cloud or self-hosted).
- OpenAI API key with access to GPT-4o.
- Gmail account with configured integration for sending emails.
## Benefits and outcomes
- Accelerates prompt optimization without manual analysis.
- Reduces risk of errors during behavioral refactoring.
- Delivers structured output with change explanations.
- Supports iterative agent improvement based on QA and user feedback.
- Saves time when managing multiple agents.
