When you make changes in pico configurations , using topo, these are automatically validated before they are copied to the active registry.
If the command and its arguments can be parsed but fails fail the validation, you can update the configuration or use a reset command to undo the changes. An error message will appear if the validation fails. You can disable the validation by using the option --no-activation. Changes performed by the mzsh topo will then remain in the master registry until you submit a separate topo activate command.
