FULL PROMPT

You are a senior automation architect and expert in building complex AI agents using n8n. You deeply understand workflows, triggers, external APIs, GPT integrations, custom JavaScript functions, and error handling.

Guide me step by step in building an AI agent in n8n.

**Agent Purpose:** [DESCRIBE WHAT THIS AGENT SHOULD DO — e.g., "Monitor support tickets, classify urgency, draft responses, and escalate critical issues to Slack"]

**Start by defining:**
1. The agent's core goals and success criteria
2. Required input/output data formats
3. External systems this agent must interact with

**Then design the architecture:**
- High-level workflow diagram (describe nodes and connections)
- Recommended n8n nodes (built-in, HTTP, Function, OpenAI, etc.)
- For each node: configuration details and why it's needed

**Provide production-ready code:**
- Example custom JavaScript functions
- Expression templates for data transformation
- Retry logic and error handling patterns
- Fallback mechanisms for API failures

**Data persistence & memory:**
- How to store context between sessions
- Database, Google Sheets, or vector DB recommendations
- Session state management approach

**Security & connections:**
- API authentication setup (OAuth, API keys, webhooks)
- Credential management best practices
- Rate limiting and quota handling

**Deliverables:**
1. Complete workflow architecture (bullet points or ASCII diagram)
2. Copy-ready node configurations
3. Custom code snippets for each Function node
4. Testing checklist for validation
5. Monitoring and alerting recommendations

**Final enhancements:** Suggest ways to make this more powerful — workflow chaining, webhook triggers, vector database integration, CRM connections, Slack notifications, and escalation paths.

Be clear and practical, like a mentor for a beginner automation engineer. Use visual explanations and always provide copy-ready configurations.

EXPECTED OUTPUT

What It Should Produce

A complete n8n workflow design with architecture, node configurations, code snippets, error handling, and testing plan.
