 ### TypeScript compilation steps
 - If the `#runTasks/getTaskOutput` tool is available, check the `VS Code - Build` watch task output for compilation errors. This task runs `Core - Build` and `Ext - Build` to incrementally compile VS Code TypeScript sources and built-in extensions. Start the task if it's not already running in the background.
 - If the tool is not available (e.g. in CLI environments) and you only changed code under `src/`, run `npm run compile-check-ts-native` after making changes to type-check the main VS Code sources (it validates `./src/tsconfig.json`).
-- If you changed built-in extensions under `extensions/` and the tool is not available, run the corresponding gulp task `gulp compile-extensions` instead so that TypeScript errors in extensions are also reported.
+- If you changed built-in extensions under `extensions/` and the tool is not available, run the corresponding gulp task `npm run gulp compile-extensions` instead so that TypeScript errors in extensions are also reported.
 - For TypeScript changes in the `build` folder, you can simply run `npm run typecheck` in the `build` folder.
