This code seems to be duplicated across your project.

                if (false === $self->io->isVerbose()) return;

Please always use braces to surround the code block of IF statements.

It is generally a best practice to always use braces with control structures.

                    if (!$hasOutput) {

            if ($this->cli->execute($command, $outputter, $this->cwd) <> 0) {

$outputter is of type object<Closure>, but the function expects a object<Webcreate\Util\Closure>|string|array|null.

It seems like you are loosely comparing $this->cli->execute($command, $outputter, $this->cwd) of type integer|null to 0; this is ambiguous as not only 0 == 0 is true, but null == 0 is true, too. Consider using a strict comparison ===.
