[Feature Request]: `carryover` as an optional argument

[xwyzsn]

Is your feature request related to a problem? Please describe.

I would like to be able to customize which agents carry context information.

Describe the solution you'd like

Making "carryover" an optional parameter might be better, as it provides flexibility, allowing users to choose whether to retain context.
