Add Gemini-powered auto-posting script with OpenAI fallback for sports content automation

[Copilot]

Implements modular Python automation for GLOBAL SPORTS WATCH that processes contributor RSS feeds, generates AI-optimized summaries via Gemini Flash (with OpenAI fallback), and applies tier-based XML overlays for Ko-fi monetization.

Core Implementation

auto_post.py (554 lines, 7 classes)

• GeminiClient / OpenAIClient - Dual AI providers with automatic failover on incomplete output (validates len(summary) > MIN_SUMMARY_LENGTH)
• RSSParser - Extracts posts and Ko-fi tier metadata (free/bronze/silver/gold) from feed tags
• XMLTemplateGenerator - Generates tier-specific overlays with watermark/ad settings per TIER_CONFIG
• AuditLogger - JSON logging to publishing_audit.json for monetization attribution

Tier-based monetization matrix:

TIER_CONFIG = {
    'free':   {'overlay': 'basic',    'watermark': True,  'ads_enabled': True,  'priority': 4},
    'bronze': {'overlay': 'standard', 'watermark': True,  'ads_enabled': True,  'priority': 3},
    'silver': {'overlay': 'premium',  'watermark': False, 'ads_enabled': False, 'priority': 2},
    'gold':   {'overlay': 'elite',    'watermark': False, 'ads_enabled': False, 'priority': 1}
}

Configuration & Automation

• GitHub Secrets integration - Loads GEMINI_API_KEY, OPENAI_API_KEY, RSS_FEED_URL via environment
• .github/workflows/auto-post.yml - Scheduled execution every 6 hours with artifact upload
• Configurable limits - MAX_RSS_ENTRIES env var controls batch size (default: 10)

Testing & Documentation

• test_auto_post.py - 6 validation categories (dependencies, imports, class instantiation, XML generation)
• docs/AUTO_POST_GUIDE.md - Technical reference with GitHub Actions setup
• docs/REVENUE_STRATEGY.md - Monetization analysis ($500-7k/month potential, 2500%+ ROI)
• QUICK_START.md - 5-minute setup workflow

Example Usage

from auto_post import AutoPoster, APIConfig

config = APIConfig()  # Loads from environment
poster = AutoPoster(config)
poster.process_posts()  # Fetches RSS, generates summaries, creates XML overlays

Output artifacts:

• overlay_{tier}_{timestamp}.xml - Tier-specific templates
• publishing_audit.json - Structured action log with monetization flags
• auto_post_audit.log - Console output

Security

• CodeQL: 0 vulnerabilities
• GitHub Actions permissions scoped to contents: read
• No hardcoded credentials (all via os.getenv)

<issue_title>Gemini-Powered Auto-Posting Script with OpenAI Fallback</issue_title>
<issue_description>Scaffold a modular auto_post.py script for GLOBAL SPORTS WATCH that:

• Loads Gemini API key securely via GitHub Secrets
• Parses RSS feed for contributor-submitted sports content
• Applies XML overlay templates based on Ko-fi tier
• Uses Gemini Flash for branded summaries and thumbnails
• Falls back to OpenAI if Gemini fails or returns incomplete output
• Logs publishing actions for audit tracking and monetization flags

This module supports contributor empowerment, tier-based publishing logic, and automated syndication across RSS, Ko-fi, and external channels.

<agent_instructions>Act as a business builder and conversion-focused growth engineer.

Primary Goal:
Turn this website into a revenue-generating asset as quickly as possible using affiliate marketing and automation.

Monetization Strategy:

• Design the site to drive clicks and sign-ups for affiliate offers (priority: high-commission, high-intent offers).
• Place affiliate links above the fold and within high-conversion sections (hero, comparison tables, CTAs).
• Optimize copy for buyer and action intent, not generic information.

Website Implementation:

• Add clear landing sections that explain the value in simple language.
• Build trust elements (benefits, FAQs, social proof placeholders, risk disclaimers).
• Create conversion-focused layouts: product cards, feature comparisons, and strong call-to-action buttons.
• Ensure fast load speed and mobile-first design.

Traffic & Growth:

• Structure pages for SEO targeting long-tail, high-intent keywords.
• Prepare the site for easy content scaling (blog posts, reviews, comparisons).
• Add basic analytics or tracking hooks for clicks and conversions.

Automation:

• Automate repetitive content or layout patterns.
• Make it easy to add new affiliate offers without redesigning the site.
• Keep maintenance minimal and costs near zero.

Decision Rules:

• Prioritize revenue impact over visual perfection.
• Avoid features that don’t directly support conversions.
• Explain how each change contributes to making money.

Deliverables:

• Open a pull request with production-ready changes.
• Include a brief revenue strategy summary in the PR description.
• List next monetization steps after deployment.

Constraints:

• No paid tools or services.
• No policy violations or misleading claims.
• Keep implementation simple, scalable, and compliant.</agent_instructions>
