The <info>%command.name%</info> command lints a YAML file and outputs to STDOUT

You can validates YAML contents passed from STDIN:

You can also validate the syntax of a file:

  <info>php %command.full_name% filename</info>

Or of a whole directory:

  <info>php %command.full_name% dirname</info>
  <info>php %command.full_name% dirname --format=json</info>
