  - Services: ⏳ Will call all 6 microservices in sequence
  - Purpose: 🎯 Core automation pipeline

🎯 IMMEDIATE NEXT STEPS (EXACT ACTIONS NEEDED)
CURRENT TASK: Complete Webhook Trigger Setup
Step 1: Configure Webhook Trigger (Now)
In n8n "Development Pipeline - Main" workflow:

1. Delete current Manual Trigger node
2. Add "Webhook" trigger node
3. Configure:
   - HTTP Method: POST
   - Path: /generate
   - Accept JSON payload with:
     * projectName (string)
     * requirements (string)  
     * techStack (string)
Step 2: Add First Service Call (Next 15 minutes)
After Webhook:
1. Add HTTP Request node
2. Configure for Requirement Processor:
   - Method: POST
   - URL: http://pipeline_requirement_processor:8001/api/v1/process
   - Body: JSON with webhook data
Step 3: Chain All Services (Next 30 minutes)
Build complete service chain:
Webhook → Requirement Processor → Tech Stack Selector → 
Architecture Designer → Code Generator → Test Generator → 
Deployment Manager → Final Response
Test Data for Development:
json{
  "projectName": "My Blog App",
  "requirements": "A simple blog with user authentication and post creation",
  "techStack": "React + Node.js"
}
