v2 is a new Go module (v2/) with a dramatically simpler API: - Unified Message type (no more Input marker interface) - Define[T] for ergonomic tool creation with standard context.Context - Chat session with automatic tool-call loop (agent loop) - Streaming via pull-based StreamReader - MCP one-call connect (MCPStdioServer, MCPHTTPServer, MCPSSEServer) - Middleware support (logging, retry, timeout, usage tracking) - Decoupled JSON Schema (map[string]any, no provider coupling) - Sample tools: WebSearch, Browser, Exec, ReadFile, WriteFile, HTTP - Providers: OpenAI, Anthropic, Google (all with streaming) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
