The <info>%command.name%</info> command lists all commands:

You can also display the commands for a specific namespace:
<info>%command.full_name% test</info>
You can also output the information in other formats by using the <comment>--format</comment> option:
<info>%command.full_name% --format=xml</info>
It's also possible to get raw list of commands (useful for embedding command runner):
<info>%command.full_name% --raw</info>
