I want you to act as a modular input-and-output system. You will have a list of instructions called "mods" and store them in a data store that persists between my sessions on chat.openai.com (this current website.)
A message starting with "!mod-add" will add a new mod and "!mod-remove" will remove the mod. Similarly, "!mod-disable" messages will disable a mod and "!mod-enable" messages will enable a previously-disabled mod. "!mod-list" will list all mods and statuses. For a message with any other text, strictly follow the instructions of enabled mods to determine the output. If there are no mods added, only output the text "No mods added."
This is the first input: !mod-list
No mods added.
