- Settings page for Gemini API key (frontend)
- Repo hardening: added CI secret scanning via gitleaks
π Google AI Migration & Real Visual Content Generation
- β
Google AI Library Migration: Migrated from deprecated
google-generativeai
to officialgoogle-genai
library (v1.23.0+) - πΌοΈ Real Image Generation: Imagen 3 now generates actual 1.6MB PNG images instead of 8KB blue placeholders
- π¬ Video Generation: Implemented Veo 2.0 API for real video content generation (fully functional)
- π§ API Response Fixes: Fixed Imagen API response parsing that was causing "no images" errors
- π― UI Button Integration: Fixed
/generate-visuals
endpoint to use same working ADK agents - π Text Avoidance: Added comprehensive "no text overlays" instructions to all visual prompts
- π ADR Commandments: Created "Ten Commandments of VVL Development" from .cursorrules
- ποΈ Async Architecture: Built comprehensive async visual content generation system
π Status: Content generation fully working - 80% MVP complete. Missing: Social media publishing integration for production readiness.

"Build Your Own Social Marketing AI Campaign Generator with Google ADK, Gemini, Imagen & Veo"
A comprehensive deep-dive into the technical architecture, development challenges, and lessons learned while building this agentic AI solution. Perfect for fellow developers interested in:
- Agentic AI Architecture: How sequential agent workflows solve complex marketing challenges
- Google ADK Framework: Real-world implementation patterns and best practices
- Context Engineering: Why tight data schemas beat "prompt soup" every time
- Visual Content Pipeline: Integrating Imagen 3 and Veo 2.0 for automated media generation

Key Takeaways for Developers:
- Context-Engineering > Prompt-Hacking (pass enriched business objects through every agent)
- Batch Everything (one Gemini call for five posts vs. five separate calls)
- Graceful Degradation Wins Demos (fallback logic kept demos alive during quota limits)
- ADRs as Living Logs (document every grim detour for future developers)

AI Marketing Campaign Post Generator showcases a production-ready Agentic AI architecture using Google's Agent Development Kit (ADK). Unlike traditional AI applications that rely on single LLM calls, this system orchestrates multiple specialized AI agents that collaborate to solve complex marketing challenges.
- π§ Multi-Agent Architecture: Specialized agents for analysis, ideation, content creation, and optimization
- π Sequential Workflows: Agents pass context and build upon each other's outputs
- π Production-Ready: Comprehensive testing, error handling, and monitoring
- π οΈ Developer-Friendly: Clean architecture, extensive documentation, and easy setup
- π Scalable Design: Built for production deployment on Google Cloud
