Minds: Scripts and non-agentic models as subagents

Is there a reason why we can only use agentic models as subagents in Minds? 

Non agentics as subagents (ex: characters as TTRPG players)
For example,
- If I want a tool to do conversation history delimiation detecting custom tags that aren’t standardised xml, a tiny LLM could do that.
- If I want to crate a DM campaign with independants characters who can react to the universe like players would, a GLM woudl be great.

Scripts or some mean to make new Agentic Tools (ex: dice throws)
- I’m thinking bout uses like a D24 thrower, or a custom dice thrower (using the current datetime as a seed to ensure randomness and the calculator ot parse that into a dice result).
