+reject-globalThis-modification
+==============================
+
+Reject any modification to ``globalThis`` inside the system modules.
+
+``globalThis`` is the shared global inside the system modules, and modification
+on it is visible from all modules, and it shouldn't be done unless it's really
+necessary.
+
+Examples of incorrect code for this rule:
+-----------------------------------------
+
+.. code-block:: js
+
+    globalThis.foo = 10;
+    Object.defineProperty(globalThis, "bar", { value: 20});
+    ChromeUtils.defineESModuleGetters(globalThis, {
+      AppConstants: "resource://gre/modules/AppConstants.sys.mjs",
+    });
