TRIZ Agent System

A sophisticated multi-agent orchestration system implementing TRIZ (Theory of Inventive Problem Solving) methodology with Gemini-style streaming architecture.

🚀 System Status: OPERATIONAL

✅ Working Features

• Multi-Agent Orchestration: Gemini-style async streaming with 5 specialized agents
• Chat Interface: Real-time web UI with Server-Sent Events
• REST APIs: Chat (streaming/non-streaming), Search, Problems management
• Vector Search: 79.6% accuracy using local Ollama embeddings
• Database: PostgreSQL with 16 comprehensive models via Prisma ORM

🎯 Quick Start

Prerequisites

• PostgreSQL 14+
• Node.js 18+
• Ollama (for local embeddings)
• Gemini API key

Installation & Setup

# 1. Clone repository
git clone <repository-url>
cd triz-agent-project

# 2. Install dependencies
npm install

# 3. Configure environment
cp .env.example .env
# Edit .env and add your GEMINI_API_KEY

# 4. Setup database
npx prisma generate
npx prisma db push

# 5. Start Ollama
ollama serve
ollama pull nomic-embed-text

# 6. Seed TRIZ principles
node scripts/seed-principles.js

# 7. Start application
npm run dev

Access the application at: http://localhost:5173

🤖 TRIZ Agents

1. Problem Analysis Agent - Extracts constraints and requirements
2. Contradiction Identifier - Identifies technical/physical contradictions
3. Solution Generator - Generates solutions using TRIZ principles
4. Principle Applicator - Applies specific TRIZ principles
5. Evaluation Agent - Evaluates and ranks solutions

📡 API Endpoints

Chat API

# Non-streaming
curl -X POST http://localhost:5173/api/chat \
  -H "Content-Type: application/json" \
  -d '{"message": "What is TRIZ?", "streaming": false}'

# Streaming (Server-Sent Events)
curl -X POST http://localhost:5173/api/chat \
  -H "Content-Type: application/json" \
  -d '{"message": "Explain segmentation principle", "streaming": true}'

Search API

curl -X POST http://localhost:5173/api/search \
  -H "Content-Type: application/json" \
  -d '{"query": "segmentation", "type": "principles"}'

Problems API

# Create problem
curl -X POST http://localhost:5173/api/problems \
  -H "Content-Type: application/json" \
  -d '{
    "title": "Weight Reduction Challenge",
    "description": "Reduce component weight by 30%",
    "industry": "Aerospace"
  }'

# List problems
curl http://localhost:5173/api/problems

🛠️ Technology Stack

• Frontend: SvelteKit, TypeScript, Tailwind CSS
• Backend: Node.js, Prisma ORM

📂 Project Organization

• /src - Source code
• /prisma - Database schema
• /scripts - Utility scripts
• /tests - Test files
