Set up Vercel AI SDK infrastructure

🛠️ Set up Vercel AI SDK Infrastructure

Overview

Establish the foundation for AI-powered conversations with streaming responses, tool calling, and provider-agnostic architecture.

---

Goals

• Unified AI interface supporting multiple providers (OpenAI, Anthropic, Google)
• Streaming responses for natural conversation feel
• Tool calling framework for actions (meetings, breathing exercises, etc.)
• TypeScript-first implementation for React Native compatibility

---

Technical Requirements

Dependencies

npm install ai @ai-sdk/openai @ai-sdk/anthropic
npm install react-native-ai-sdk  # or equivalent RN wrapper

Core Components

Component	Purpose
AI Provider Config	Switch between OpenAI/Anthropic based on cost/performance
Streaming Handler	Manage real-time response streams
Tool Registry	Define available actions (findMeeting, startBreathing, etc.)
Context Manager	Maintain conversation history

---

Implementation Tasks

• Install and configure Vercel AI SDK
• Set up AI provider configuration (env-based switching)
• Implement streaming response handling
• Create tool calling framework
• Set up mem0 integration (Implement mem0 user memory system #423)
• Configure context management
• Add error handling and fallbacks
• Write unit tests for AI interactions

---

Acceptance Criteria

• AI responses stream in real-time
• Tool calls execute correctly (test with mock tools)
• Provider switching works without code changes
• Failed AI calls gracefully degrade
• Unit tests cover >80% of AI module

---

Technical Notes

• Use environment variables for API keys (never commit keys)
• Implement request/response logging for debugging
• Consider rate limiting and cost monitoring
• Set up A/B testing framework for model comparison
