+## File
+- games/_template/README.md
+
+## Add
+- required import patterns (src/shared, src/engine)
+- forbid relative climbing (../../)

+## Constraints

+## Import Rules
+
+Use direct project-root relative imports for shared and engine modules:
+
+```js
+import { sanitizeText } from "src/shared/utils/stringUtils.js";
+import { createEngineLoop } from "src/engine/core/createEngineLoop.js";
+```
+
+Do not use relative climbing imports like `../../` inside games code.
