Omni provides a number of built-in commands. Those are available from anywhere omni can be called, and will be called from the current working directory.
Those commands take precedence over any custom commands, makefile commands or configuration commands, it is thus not possible to override them. However, you can still write "subcommands" for those, that would be called when the specific subcommand is being called.
