# 1. Navigate to project
cd C:\Users\timud\Documents\product-trend-automation

# 2. Check all services are running
docker ps --filter "name=product-trend"

# 3. Check logs to verify system health
docker logs product-trend-celery --tail 50
docker logs product-trend-backend --tail 50

# 4. Access the system

# Backend API: http://localhost:8000
# API Docs: http://localhost:8000/docs

What This System Does

Product Trend Automation System - An AI-powered platform that:

Discovers trending products from 7 sources (Amazon, TikTok, Reddit, etc.)
Analyzes products using 12 AI agents (11 Groq + 1 Perplexity)
Learns from discoveries via Perplexity feedback loop
Recommends products with APPROVE/REVIEW/REJECT decisions
Auto-posts to marketplaces (requires manual approval by default)

Key Innovation: Self-improving feedback loop where Perplexity discovers trending keywords, stores them, and TrendScanner uses them for future searches.

What Changed This Session

Session Goal

Add Perplexity as 12th agent + create feedback loop + enhance all agents with improved instructions.

Changes Made

1. Perplexity Integration

Files Created:

backend/services/trend_discovery/perplexity_discovery.py (318 lines)
- PerplexityTrendDiscovery class
- discover_trending_products() - Web search for trends
- update_trend_scanner_intel() - Feedback loop implementation
- _store_trending_keywords() - Database storage

Files Modified:

.env - Added PERPLEXITY_API_KEY=your_perplexity_api_key_here
backend/services/ai_analysis/agentic_system.py:
- Line 27: Added perplexity_api_key parameter
- Line 32: Added perplexity_url
- Line 55: Changed model from llama-3.1-sonar-large-128k-online to sonar
- Lines 800-1060: Added _run_perplexity_agent() method (260 lines)
- Enhanced all 12 agent prompts with ultra-clear instructions

2. Database Schema

File: backend/models/database.py Added: TrendingKeyword model (lines 115-143)

class TrendingKeyword(Base):
    __tablename__ = "trending_keywords"

    id = Column(Integer, primary_key=True)
    keyword = Column(String(200), unique=True, nullable=False)
    category = Column(String(200))
    trend_strength = Column(String(50))
    search_count = Column(Integer, default=1)
    last_seen = Column(DateTime)
    first_discovered = Column(DateTime)
    related_products = Column(JSON)
    source_urls = Column(JSON)
    expires_at = Column(DateTime)  # 30-day expiry
    created_at = Column(DateTime)
    updated_at = Column(DateTime)

Status: Table created successfully. 28 keywords currently stored.

3. Celery Tasks

File: backend/tasks/trend_tasks.py Added: perplexity_discovery_task() (lines 51-103)

Runs Perplexity web search
Stores discovered keywords
Returns: products_discovered, keywords_extracted, hot_categories

File: backend/tasks/celery_app.py Added: Perplexity schedule (lines 42-45)

'perplexity-discovery': {
    'task': 'tasks.trend_tasks.perplexity_discovery_task',
    'schedule': crontab(minute=0, hour='*/6'),  # Every 6 hours
},

4. TrendScanner Enhancement

File: backend/services/trend_discovery/trend_scanner.py Added:

Line 12: Import TrendingKeyword
Line 34: self.discovered_keywords = []
Line 63: Call to _load_discovered_keywords(db)
Lines 925-968: New methods:
- _load_discovered_keywords() - Loads from DB
- has_trending_keywords() - Matches products to keywords

Functionality: Scanner now loads Perplexity keywords and can prioritize matching products.

5. Agent Instruction Enhancement

File: backend/services/ai_analysis/agentic_system.py Enhanced all 12 agents with detailed format:

Before:

prompt = "Analyze this product and return a score."

After (example - Scanner Agent, ~200 lines):

prompt = f"""You are Dr. Sarah Chen, PhD, a Senior Product Analyst...

YOUR TASK - COMPREHENSIVE PRODUCT INTELLIGENCE:

**STEP 1: Category Precision** (Use marketplace taxonomy)
- Analyze product and map to exact marketplace category hierarchy
- Format: "Main > Sub > Micro > Ultra-Specific" (4 levels minimum)
- Examples:
  * Good: "Electronics > Audio > Headphones > True Wireless Earbuds"
  * Poor: "Electronics" (too broad)
- Think: Where would Amazon/eBay list this for maximum visibility?

**STEP 2: Keyword Research** (SEO & Marketplace Optimization)
[... continues with detailed methodology ...]

**QUALITY STANDARDS CHECKLIST:**
Before submitting, verify:
[COMPLETE] Category has 4 levels of specificity
[COMPLETE] Keywords are 8-12 actual search terms (not fluff)
[COMPLETE] Competitive advantage is specific (not generic)
[... etc ...]

**EXCELLENT EXAMPLE:**
{
  "category": "Home & Kitchen > Kitchen & Dining > Coffee, Tea & Espresso > Coffee Makers > Drip Coffee Machines",
  "keywords": ["programmable coffee maker", "12 cup drip brewer", ...]
}

**POOR EXAMPLE:**
{
  "category": "Kitchen",  // X Too broad
  "keywords": ["best coffee maker", "great brewer"]  // X Generic fluff
}
"""

Enhanced Agents:

Scanner: 200 lines
Trend: 230 lines
Research: 260 lines
Perplexity: 260 lines
Coordinator: 140 lines
Specialists (8 agents): 40-80 lines each

Total: ~1800+ lines of ultra-detailed agent instructions

Testing Results

Test 1: Perplexity Discovery [SUCCESS]

# Command run:
docker exec product-trend-celery celery -A tasks.celery_app call tasks.trend_tasks.perplexity_discovery_task

# Result:
[COMPLETE] Discovery complete!
[STATS] Found 7 trending products
[STATS] Found 28 trending keywords
[STORAGE] Stored 28 keywords in database
[UPDATE] System intelligence updated

Keywords discovered:

skin repair patches, kojic acid serum, TikTok perfume
nail bloom effect, Sweetcrispy chair, boucle chair
microneedle patches, nail art gel, textured chair
print on demand phone case, shockproof case
Topicals Faded Serum, affordable perfume
[... 15 more]

Test 2: TrendScanner Feedback Loop [SUCCESS]

# Command run:
docker exec product-trend-celery celery -A tasks.celery_app call tasks.trend_tasks.scan_trends_task

# Result:
[FEEDBACK LOOP] Loaded 20 trending keywords from Perplexity:
   1. skin repair patches
   2. kojic acid serum
   [... 18 more]
[INFO] Scanner will prioritize products matching these keywords

[SCAN SUMMARY]:
   Sources Scanned: 7
   Products Discovered: 53
   Products Accepted: 53
   Products Created: 0 (all duplicates of existing)

Test 3: 12-Agent Analysis [SUCCESS]

# Command run:
docker exec product-trend-celery celery -A tasks.celery_app call tasks.analysis_tasks.analyze_single_product --args='[399]'

# Product: Ergonomic Split Mechanical Keyboard

# Result (17.48s total):
[COMPLETE] Scanner: Category mapping, keywords extracted
[COMPLETE] Trend: Trend analysis complete
[COMPLETE] Research: Financial analysis complete
[COMPLETE] Quality: 85/100
[COMPLETE] Pricing: $149.99
[COMPLETE] Viral: 72/100
[COMPLETE] Competition: medium
[COMPLETE] Supply Chain: 35 days lead time
[COMPLETE] Psychology: 75/100 fit
[COMPLETE] Data Science: rising trend 90%
[COMPLETE] Perplexity: Web search (model corrected, now working)
[COMPLETE] Coordinator: Synthesis (hit rate limit - using fallback)

Note: Coordinator hit Groq rate limit (429 error). This is normal for free tier during testing. System gracefully falls back to merging agent data without coordinator synthesis.

Key Technical Details

Perplexity API

Endpoint: https://api.perplexity.ai/chat/completions
Model: sonar (was llama-3.1-sonar-large-128k-online - FIXED)
Auth: Bearer token in header
Rate Limit: Free tier - 5 requests/minute
Response Time: ~40 seconds per discovery run

Groq API

Endpoint: https://api.groq.com/openai/v1/chat/completions
Models Used:
- Qwen3 32B (qwen/qwen3-32b) - Coordinator, Trend, Research
- Llama-3.3 70B (llama-3.3-70b-versatile) - Scanner
- Llama-3.1 8B (llama-3.1-8b-instant) - 8 specialist agents
Rate Limit: Free tier - 14,400 requests/day
Current Usage: ~100-200 requests/day (97% headroom)
Delay Between Calls: 0.8s (rate-limit friendly)

Database Connection

# PostgreSQL connection (inside Docker)
DATABASE_URL=postgresql://postgres:postgres@postgres:5432/product_trends

# From host machine
DATABASE_URL=postgresql://postgres:postgres@localhost:5432/product_trends

Celery Configuration

Broker: Redis (redis://redis:6379/0)
Backend: Redis (same)
Serializer: JSON
Timezone: UTC
Workers: 32 (prefork)

Known Issues & Limitations

1. Groq Rate Limits (Free Tier)

Issue: Coordinator occasionally hits 429 Too Many Requests during heavy testing. Impact: Low - System uses fallback merge when this happens. Mitigation:

0.8s delay between agent calls
Fallback logic in place
For production: Upgrade to paid tier or implement smarter queuing

2. Perplexity Model Name Confusion

Issue: Model was initially llama-3.1-sonar-large-128k-online (invalid). Fix Applied: Changed to sonar in both files:

[COMPLETE] backend/services/trend_discovery/perplexity_discovery.py (line 24)
[COMPLETE] backend/services/ai_analysis/agentic_system.py (line 55) Status: RESOLVED

3. Frontend Crash (Previous Session)

Issue: Frontend crashed due to missing routes. Fix Applied: Added placeholder routes. Status: RESOLVED Current Status: Frontend accessible at http://localhost:3000

4. Platform APIs Not Configured

Issue: Amazon, eBay, TikTok Shop APIs not set up (empty in .env). Impact: Cannot auto-post to marketplaces (manual approval required anyway). Next Step: User needs to obtain API credentials from each platform. Compliance: REQUIRE_MANUAL_APPROVAL=True prevents unauthorized posting.

5. HuggingFace Inference API Deprecated

Issue: HF deprecated text generation in July 2025. Fix Applied: All agents now use Groq (100% free). Status: RESOLVED (Previous session)

How to Verify Everything Works

Quick Health Check

# 1. Check all containers running
docker ps --filter "name=product-trend"
# Should show 6 containers: frontend, backend, celery, celery-beat, db, redis

# 2. Check backend health
curl http://localhost:8000/health
# Should return: {"status":"healthy"}

# 3. Check database connection
docker exec product-trend-backend python -c "from models.database import SessionLocal; db = SessionLocal(); print('DB Connected:', db.execute('SELECT 1').scalar() == 1); db.close()"
# Should print: DB Connected: True

# 4. Check trending keywords
docker exec product-trend-backend python -c "from models.database import SessionLocal, TrendingKeyword; db = SessionLocal(); count = db.query(TrendingKeyword).count(); print(f'Keywords stored: {count}'); db.close()"
# Should print: Keywords stored: 28 (or similar)

# 5. Check Celery workers
docker exec product-trend-celery celery -A tasks.celery_app inspect active
# Should show worker status and active tasks

# 6. Check scheduled tasks
docker exec product-trend-celery-beat celery -A tasks.celery_app inspect scheduled
# Should show upcoming scheduled tasks

Test Perplexity Discovery

# Trigger manual discovery
docker exec product-trend-celery celery -A tasks.celery_app call tasks.trend_tasks.perplexity_discovery_task

# Check logs for results
docker logs product-trend-celery --tail 100 | grep "PERPLEXITY DISCOVERY" -A 20

# Verify keywords stored
docker exec product-trend-backend python -c "from models.database import SessionLocal, TrendingKeyword; from datetime import datetime; db = SessionLocal(); keywords = db.query(TrendingKeyword).filter(TrendingKeyword.expires_at > datetime.utcnow()).all(); print(f'Active keywords: {len(keywords)}'); [print(f'  - {kw.keyword}') for kw in keywords[:10]]; db.close()"

Test Trend Scanner with Feedback Loop

# Run trend scan
docker exec product-trend-celery celery -A tasks.celery_app call tasks.trend_tasks.scan_trends_task

# Check logs for feedback loop
docker logs product-trend-celery --tail 200 | grep "FEEDBACK LOOP" -A 15

# Should see:
# [FEEDBACK LOOP] Loaded 20 trending keywords from Perplexity:

Test 12-Agent Analysis

# Get a product ID
docker exec product-trend-backend python -c "from models.database import SessionLocal, Product; db = SessionLocal(); p = db.query(Product).order_by(Product.id.desc()).first(); print(f'Testing product {p.id}: {p.title[:50]}'); db.close()"

# Run analysis (replace 399 with actual product ID)
docker exec product-trend-celery celery -A tasks.celery_app call tasks.analysis_tasks.analyze_single_product --args='[399]'

# Check logs
docker logs product-trend-celery --tail 150

# Should see all 12 agents execute:
# - Quality Officer, Pricing Director, Viral Specialist, etc.
# - Perplexity Web Search
# - Coordinator synthesis

Common Operations

Database Operations

# Access PostgreSQL shell
docker exec -it product-trend-db psql -U postgres -d product_trends

# Useful queries:
SELECT COUNT(*) FROM products;
SELECT COUNT(*) FROM trending_keywords;
SELECT * FROM trending_keywords ORDER BY search_count DESC LIMIT 10;
SELECT id, title, status FROM products ORDER BY id DESC LIMIT 10;

Run Python Code in Backend Container

docker exec product-trend-backend python -c "
from models.database import SessionLocal, Product, TrendingKeyword
db = SessionLocal()

# Your code here
products = db.query(Product).count()
keywords = db.query(TrendingKeyword).count()
print(f'Products: {products}, Keywords: {keywords}')

db.close()
"

Trigger Tasks Manually

# Trend scan
docker exec product-trend-celery celery -A tasks.celery_app call tasks.trend_tasks.scan_trends_task

# Analyze all pending products
docker exec product-trend-celery celery -A tasks.celery_app call tasks.analysis_tasks.analyze_pending_products_task

Next Steps & Roadmap

Immediate Next Steps

Monitor Perplexity Discovery:
- Check logs after 6 hours to see automatic discovery
- Verify keywords are being used by TrendScanner
- Track keyword lifecycle (emerging → hot → fading)
Test Platform Integration:
- Obtain Amazon SP-API credentials
- Obtain eBay developer credentials
- Obtain TikTok Shop API access
- Test posting to one platform
Frontend Development:
- Build product review dashboard
- Add keyword analytics view
- Create approval workflow UI
- Display agent analysis results

Enhancement Ideas

1. Keyword-Based Scoring Boost

# In TrendScanner._save_product()
if self.has_trending_keywords(product_data["title"], product_data.get("description", "")):
    product_data["trend_score"] += 10  # Boost products matching Perplexity discoveries

2. Perplexity On-Demand Search

# New API endpoint
@app.post("/api/discover/{category}")
async def discover_category(category: str):
    """User-triggered Perplexity search for specific category"""
    discovery = PerplexityTrendDiscovery()
    results = await discovery.discover_trending_products(category)
    return results

3. Keyword Analytics Dashboard

Show top performing keywords
Track conversion rates (keyword → product → approved)
Identify profitable patterns
Visualize keyword lifecycle

4. Multi-Source Keyword Validation

# Validate Perplexity keywords against Google Trends
# Filter out false positives
# Score keywords by multi-source agreement

5. Smart Product Matching

# When keyword found, search marketplaces for exact products
# Example: "skin repair patches" → search Amazon for exact matches
# Auto-import product data from marketplaces

Performance Optimizations

Agent Parallelization:
- Current: Sequential (0.8s delays for rate limits)
- Future: Parallel with smarter rate limiting
- Potential: 10x faster analysis
Caching Layer:
- Cache Perplexity results for 6 hours
- Cache agent analyses for duplicate products
- Reduce API calls by 50%
Database Indexing:
- Add index on trending_keywords.keyword
- Add index on products.trend_score
- Faster queries for matching

Troubleshooting Guide

Issue: Services won't start

# Check Docker
docker --version
docker-compose --version

# Check if ports are in use
netstat -ano | findstr :3000
netstat -ano | findstr :8000
netstat -ano | findstr :5432

# Restart Docker
# Windows: Right-click Docker Desktop → Restart
# Or: docker-compose down && docker-compose up -d

Issue: Database connection failed

# Check PostgreSQL container
docker logs product-trend-db

# Check if table exists
docker exec product-trend-db psql -U postgres -d product_trends -c "\dt"

# Reinitialize database
docker exec product-trend-backend python -c "from models.database import init_db; init_db()"

Issue: Perplexity API errors

# Check API key
docker exec product-trend-backend python -c "import os; from dotenv import load_dotenv; load_dotenv(); print('Key:', os.getenv('PERPLEXITY_API_KEY')[:20]+'...')"

# Test API directly
curl -X POST https://api.perplexity.ai/chat/completions \
  -H "Authorization: Bearer YOUR_KEY_HERE" \
  -H "Content-Type: application/json" \
  -d '{"model":"sonar","messages":[{"role":"user","content":"test"}]}'

# Check logs for error details
docker logs product-trend-celery | grep "Perplexity" -A 5

Issue: Groq rate limit errors

# This is expected on free tier during heavy testing
# Solutions:
# 1. Wait 1 minute between test runs
# 2. Increase delay in agentic_system.py (line ~98): await asyncio.sleep(1.5)
# 3. Use fallback (already implemented)
# 4. Upgrade to paid tier ($0.27/1M tokens)

Issue: Celery tasks not running

# Check Celery worker
docker logs product-trend-celery

# Check Celery beat
docker logs product-trend-celery-beat

# Check if tasks are registered
docker exec product-trend-celery celery -A tasks.celery_app inspect registered

# Restart Celery
docker restart product-trend-celery product-trend-celery-beat

Issue: Frontend not loading

# Check frontend logs
docker logs product-trend-frontend

# Check if port 3000 is accessible
curl http://localhost:3000

# Rebuild frontend
docker-compose up -d --build product-trend-frontend
