Architecture

The extension is organized in layers to isolate VS Code, DeepSeek, UI, and domain logic.

Main layers:

• src/adapters: shared contracts between the extension backend and the webview.
• src/core: pure logic, tools, and safety rules without vscode imports.
• src/deepseekApi: DeepSeek HTTP client, streaming, FIM, and tool-call protocol.
• src/infrastructure: local persistence on top of VS Code APIs.
• src/vscodeApi: activation, commands, webviews, and concrete VS Code adapters.
• src/ui/chat: React app that runs inside the webview.

Architecture goal: keep maintainable logic outside VS Code where possible, and make external API boundaries explicit.
