 # Project Rules
 
-- This project is split into `Mirserver` (server) and `client` (client).
-- Files under `Mirserver` use GB2312/GBK encoding. Read and write them with the server encoding preserved; do not silently convert them to UTF-8.
-- Files under `client` use UTF-8 encoding. Read and write them as UTF-8.
-- When changing mirrored server/client logic, keep each side in its own encoding and verify Chinese text after edits.
-- Before processing server-side code, call MCP tool: mcp_996_new_server
-- Before processing client-side code, call MCP tool: mcp_996_client
+## 编码规范（强制执行）
+- **服务端文件（Mirserver/目录下）：必须使用 GB2312/GBK 编码**
+  - 读取时必须按 GB2312/GBK 解析
+  - 写入时必须保持 GB2312/GBK 编码，绝不允许转换为 UTF-8
+  - 包括但不限于：.lua、.txt、.ini 等所有服务端文件
+- **客户端文件（client/目录下）：必须使用 UTF-8 编码**
+  - 读取和写入都使用 UTF-8 编码
+- 修改服务端/客户端逻辑时，严格保持各自的编码，编辑后必须验证中文文本正确显示
+
+## MCP工具调用
+- 处理服务端代码前，调用 MCP 工具：mcp_996_new_server
+- 处理客户端代码前，调用 MCP 工具：mcp_996_client
