## Overview

DeepSeek for Visual Studio is an IDE-native AI coding assistant. The main workflow starts in the chat panel, builds conversation context, routes work through cooperating agents and tools, calls a configured model provider, and presents results or reviewed code changes in Visual Studio. Separate branches support inline editing and Ghost Text completion. The README documents broader MCP, Skills, memory, multimodal, search, and build capabilities; links for these are shown at subsystem level where source excerpts do not establish finer wiring.

Main entry points: [`Services/Agents/AgentFactory.cs`](https://github.com/zmy15/deepseek-for-visualstudio/blob/master/Services/Agents/AgentFactory.cs) (Agent orchestration), [`View/DeepSeekChatControl.xaml.cs`](https://github.com/zmy15/deepseek-for-visualstudio/blob/master/View/DeepSeekChatControl.xaml.cs) (Chat panel), [`Services/DeepSeekApiService.cs`](https://github.com/zmy15/deepseek-for-visualstudio/blob/master/Services/DeepSeekApiService.cs) (Chat API service), [`Services/BuiltInTools`](https://github.com/zmy15/deepseek-for-visualstudio/tree/master/Services/BuiltInTools) (IDE tools)
