+Too see what tsc is seeing (say when it is trying to type-check `@/utils`), use
+`yarn workspace @/utils tsc --showConfig`.
+
+Similarly, to verify what ESLint is trying to do, use `yarn workspace @/utils
+eslint --debug .`

+If the issue is in VSCode, open the output window of the corresponding plugin,
+it might be telling us what's going wrong there. In particular, when changing
+the settings here, you might need to "Developer: Reload Window" in VSCode to get
+it to pick up the changes.
