+# Kimi K2 Provider Architecture
+
+This document describes the `KimiK2Provider` used by the extension to automate the Kimi K2 chat interface.
+
+---
+
+## 🧩 Overview
+
+`KimiK2Provider` is modeled after the existing AI Studio and ChatGPT providers. It sends messages and captures responses from `k2.kimi.ai` using DOM based monitoring by default with an optional debugger fallback.
+
+---
+
+## ⚙️ Configurable Options
+
+```js
+this.captureMethod = 'dom'; // or 'debugger'
+this.debuggerUrlPattern = '*k2.kimi.ai/api/chat*';
+this.includeThinkingInMessage = false;
+```
+
+---
+
+## 📌 DOM Selectors
+
+- Input field: `textarea, div[contenteditable="true"]`
+- Send button: `button[type="submit"], button.send-btn`
+- Response blocks: `.message.ai, .chat-message.ai`
+- Typing indicator: `.typing, .loading`
+
+---
+
+## ✅ Summary
+
+The provider offers a lightweight integration with Kimi K2 using the same structure as the other providers. It can capture responses via DOM observation or via Chrome debugger when configured.
