+## `workspace:` protocol required
+
+If `"workspaceProtocol": "require"` is set in the `manypkg` config in the root `package.json`, all dependencies on internal packages are required to use the `workspace:` protocol.
+
+### Why it's a rule
+
+If you want to enforce the usage of the `workspace:` protocol.
+
+#### How it's fixed
+
+Dependencies are changed to `workspace:^`. Anything else is also allowed after the `workspace:` though.
