To include these parameters in your assistant with common help strings etc., include them from common_args.yaml (-n, -g) or eclipse.yaml (-e) snippet:
args: name: snippet: common_args
When creating snippets/Python commands, they should operate under the assumption that current working directory is the project directory (not one dir up or anywhere else). It is the duty of assistant to switch to that directory. The benefit of this approach is that you just cd once in assistant and then call all the snippets/commands, otherwise you’d have to put 2x`cd` in every snippet/command.
