+## Claude Text Editor Tool Mode
+
+Avante leverages [Claude Text Editor Tool](https://docs.anthropic.com/en/docs/build-with-claude/tool-use/text-editor-tool) to provide a more elegant code editing experience. You can now enable this feature by setting `enable_claude_text_editor_tool_mode` to `true` in the `behaviour` configuration:
+
+```lua
+{
+  behaviour = {
+    enable_claude_text_editor_tool_mode = true,
+  },
+}
+```
+
+> [!NOTE]
+> To enable **Claude Text Editor Tool Mode**, you must use the `claude-3-5-sonnet-*` or `claude-3-7-sonnet-*` model with the `claude` provider! This feature is not supported by any other models!

 ## Custom prompts
 
 By default, `avante.nvim` provides three different modes to interact with: `planning`, `editing`, and `suggesting`, followed with three different prompts per mode.
