Multi-Agent Gift Recommendation Engine Powered by Google ADK & Gemini

GiftAdvisor is a sophisticated gift recommendation system that utilizes Google's Agent Development Kit (ADK) and the Gemini model to provide personalized gift suggestions based on a recipient's profile. The system is built with three specialized AI agents that work together in a multi-agent pipeline.

The Profile Analyzer Agent is responsible for extracting core interests, lifestyle dimensions, and anti-preferences from the user's input. This agent uses the LlmAgent component from ADK and the Gemini model to understand the recipient's description, occasion, and relationship, then saves this structured analysis in session state.

Next, the Idea Finder Agent generates 6-10 candidate gift ideas across various categories, such as experiential, practical, consumable, and sentimental items. The agent also attaches realistic estimated market prices for each idea and saves the candidate gifts in session state.

Finally, the Budget Filter Agent evaluates the candidate gifts against the user's budget limit. It eliminates any items that exceed the budget and replaces them with budget-friendly alternatives. The agent then ranks the final recommendations into budget tiers and provides specific buying advice. The final report is saved in session state.

The entire system is deployed on Google Cloud Run, which allows for cost-effective scaling to zero instances when idle. The system uses a modern Glassmorphism UI, with a dark mode interface, preset profiles, an interactive budget slider, and live pipeline stage tracking. Additionally, users can export the recommendations in various formats, including Markdown, JSON, Clipboard, or PDF.
