You can find code examples to all commonly needed operations in the script repository - see how to adjust brush parameters [here](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html#create-keyboard-shortcut-for-toggling-sphere-brush-for-paint-and-erase-effects). List of all built-in Segment Editor effect parameters is available [here](https://slicer.readthedocs.io/en/latest/developer_guide/modules/segmenteditor.html#effect-parameters).
