# HKIA Content Aggregation & Competitive Intelligence System

## Project Overview
Complete content aggregation system that scrapes 6 sources (WordPress, MailChimp RSS, Podcast RSS, YouTube, Instagram, HVACRSchool), converts to markdown, and runs twice daily with incremental updates. TikTok scraper disabled due to technical issues.

**NEW: Phase 3 Competitive Intelligence Analysis** - Advanced competitive intelligence system for tracking 5 HVACR competitors with AI-powered analysis and strategic insights.

## Architecture

### Core Content Aggregation
- **Base Pattern**: Abstract scraper class (`BaseScraper`) with common interface
- **State Management**: JSON-based incremental update tracking in `data/.state/`
- **Parallel Processing**: All 6 active sources run in parallel via `ContentOrchestrator`
- **Output Format**: `hkia_[source]_[timestamp].md`
- **Archive System**: Previous files archived to timestamped directories in `data/markdown_archives/`
- **Media Downloads**: Images/thumbnails saved to `data/media/[source]/`
- **NAS Sync**: Automated rsync to `/mnt/nas/hkia/`

### ✅ Competitive Intelligence (Phase 3) - **PRODUCTION READY**
- **Engine**: `CompetitiveIntelligenceAggregator` extending base `IntelligenceAggregator`
- **AI Analysis**: Claude Haiku API integration for cost-effective content analysis  
- **Performance**: High-throughput async processing with 8-semaphore concurrency control
- **Competitors Tracked**: HVACR School, AC Service Tech, Refrigeration Mentor, Love2HVAC, HVAC TV
- **Analytics**: Market positioning, content gap analysis, engagement comparison, strategic insights
- **Output**: JSON reports with competitive metadata and strategic recommendations
- **Status**: ✅ **All critical issues fixed, ready for production deployment**

## Key Implementation Details

### Instagram Scraper (`src/instagram_scraper.py`)
- Uses `instaloader` with session persistence
- Aggressive rate limiting: 15-30 second delays, extended breaks every 5 requests
- Session file: `instagram_session_hkia1.session`
- Authentication: Username `hkia1`, password `I22W5YlbRl7x`

### ~~TikTok Scraper~~ ❌ **DISABLED**
- **Status**: Disabled in orchestrator due to technical issues
- **Reason**: GUI requirements incompatible with automated deployment
- **Code**: Still available in `src/tiktok_scraper_advanced.py` but not active

### YouTube Scraper (`src/youtube_hybrid_scraper.py`)
- **Hybrid Approach**: YouTube Data API v3 for metadata + yt-dlp for transcripts
- Channel: `@HVACKnowItAll` (38,400+ subscribers, 447 videos)
- **API Integration**: Rich metadata extraction with efficient quota usage (3 units per video)
- **Authentication**: Firefox cookie extraction + PO token support via `YouTubePOTokenHandler`
- ❌ **Transcript Status**: DISABLED due to YouTube platform restrictions (Aug 2025)
  - Error: "The following content is not available on this app"
  - **PO Token Implementation**: Complete but blocked by YouTube platform restrictions
  - **179 videos identified** with captions available but currently inaccessible
  - Will automatically resume transcript extraction when platform restrictions are lifted

### RSS Scrapers
- **MailChimp**: `https://us10.campaign-archive.com/feed?u=d1a98c3e62003104038942e21&id=2205dbf985`
- **Podcast**: `https://feeds.libsyn.com/568690/spotify`

### WordPress Scraper (`src/wordpress_scraper.py`)
- Direct API access to `hvacknowitall.com`
- Fetches blog posts with full content

### HVACRSchool Scraper (`src/hvacrschool_scraper.py`)
- Web scraping of technical articles from `hvacrschool.com`
- Enhanced content cleaning with duplicate removal
- Handles complex HTML structures and embedded media

## Technical Stack
- **Python**: 3.11+ with UV package manager
- **Key Dependencies**: 
  - `instaloader` (Instagram)
  - `scrapling[all]` (TikTok anti-bot)
  - `yt-dlp` (YouTube)
  - `feedparser` (RSS)
  - `markdownify` (HTML conversion)
- **Testing**: pytest with comprehensive mocking

## Deployment Strategy

from src.content_analysis.competitive.competitive_aggregator import CompetitiveIntelligenceAggregator
from pathlib import Path
import asyncio

async def main():
    aggregator = CompetitiveIntelligenceAggregator(Path('data'), Path('logs'))
    
    # Process competitive content for all competitors
    results = {}
    competitors = ['hvacrschool', 'ac_service_tech', 'refrigeration_mentor', 'love2hvac', 'hvac_tv']
    
    for competitor in competitors:
        print(f'Processing {competitor}...')
        results[competitor] = await aggregator.process_competitive_content(competitor, 'backlog')
        print(f'Processed {len(results[competitor])} items for {competitor}')
    
    print(f'Total competitive analysis completed: {sum(len(r) for r in results.values())} items')

asyncio.run(main())
"

# Generate competitive intelligence reports
uv run python -c "
from src.content_analysis.competitive.competitive_reporter import CompetitiveReportGenerator
from pathlib import Path

reporter = CompetitiveReportGenerator(Path('data'), Path('logs'))
reports = reporter.generate_comprehensive_reports(['hvacrschool', 'ac_service_tech'])
print(f'Generated {len(reports)} competitive intelligence reports')
"

# Export competitive analysis results
ls -la data/competitive_intelligence/reports/
cat data/competitive_intelligence/reports/competitive_summary_*.json
```

### Production Operations
```bash
# Service management (✅ ACTIVE SERVICES)
sudo systemctl status hkia-scraper.timer
sudo systemctl status hkia-scraper-nas.timer

ls -la data/markdown_current/
ls -la data/media/[source]/
```

## Critical Notes

1. **✅ TikTok Scraper**: DISABLED - No longer blocks deployment or requires GUI access
2. **Instagram Rate Limiting**: 100 requests/hour with exponential backoff
3. **YouTube Transcript Status**: DISABLED in production due to platform restrictions (Aug 2025)
   - Complete PO token implementation but blocked by YouTube platform changes
   - 179 videos identified with captions but currently inaccessible
   - Hybrid scraper architecture ready to resume when restrictions are lifted
4. **State Files**: Located in `data/.state/` directory for incremental updates
5. **Archive Management**: Previous files automatically moved to timestamped archives in `data/markdown_archives/[source]/`
6. **Media Management**: Images/videos saved to `data/media/[source]/` with consistent naming
7. **Error Recovery**: All scrapers handle rate limits and network failures gracefully
8. **✅ Production Services**: Fully automated with systemd timers running twice daily
9. **Package Management**: Uses UV for fast Python package management (`uv run`, `uv sync`)

## YouTube Transcript Status (August 2025)

**Current Status**: ❌ **DISABLED** - Transcripts extraction disabled in production

**Implementation Status**:
- ✅ **Hybrid Scraper**: Complete (`src/youtube_hybrid_scraper.py`)
- ✅ **PO Token Handler**: Full implementation with environment variable support
- ✅ **Firefox Integration**: Cookie extraction and profile detection working
- ✅ **API Integration**: YouTube Data API v3 for efficient metadata extraction
- ❌ **Transcript Extraction**: Disabled due to YouTube platform restrictions

**Technical Details**:
- **179 videos identified** with captions available but currently inaccessible
- **PO Token**: Extracted and configured (`YOUTUBE_PO_TOKEN_MWEB_GVS` in .env)
- **Authentication**: Firefox cookies (147 extracted) + PO token support
- **Platform Error**: "The following content is not available on this app"

**Architecture**: True hybrid approach maintains efficiency:
- **Metadata**: YouTube Data API v3 (cheap, reliable, rich data)
- **Transcripts**: yt-dlp with authentication (currently blocked)
- **Fallback**: Gracefully continues without transcripts

**Future**: Will automatically resume transcript extraction when platform restrictions are resolved.
