Gulp script messes up git repository (?)

Question

Is there any probability a simple gulp script (running under laravel installation) messed up my git repository?
Without any visible reason (no add, no commit, only file editing) at one point all files in git repository folder is marked to add.
"git status" return me all files and folders are deleted, and to re add it all.

this is the gulp script:

gulp.task('foorwatch', function() {
    gulp.watch([config.SASS_SRC])
        .on("change", function(file) {
            gulp.src(file.path, { sourcemaps: true })
                .pipe(plumber())
                .pipe(sourcemaps.init())
                .pipe(changed(config.SASS_SRC, {hasChanged: changed.compareLastModifiedTime}))
                .pipe(sass())
                .pipe(minifycss())
                .pipe(sourcemaps.write('maps'))
                .pipe(gulp.dest(config.CSS_DEST))
        });
});

elixir(function(mix) {
    mix.task('foorwatch')
        .browserSync({proxy: config.PROXY});
});

If not, what can cause a behaviour like this?

I'm using OSX with VSC and zsh as terminal shell.
The repository is on a ssh mounted folder and all git commands are executed via ssh connected terminal.

Thanks
