Architecture

Overview

Agent Mill uses a frontend-backend separated microservice architecture.

Layer	Technology
Backend	Python 3.11+ / FastAPI / SQLAlchemy 2.0 (async)
Frontend	Vue 3 / TypeScript / Vite / Pinia / Element Plus
Database	MySQL 8.0
Vector Search	ZVec (Alibaba, Rust kernel, embedded)
AI SDK	Claude Agent SDK (Anthropic) + OpenAI SDK

Streaming Architecture

Two streaming paths produce identical SSE events:

Anthropic Path:    Claude Agent SDK native SSE
                   → meta → thinking → text → tool_use → tool_result → file → ui → error → done

OpenAI Path:       Custom tool_calls multi-turn loop
                   → same SSE event protocol
