Prompt template overrides

[parzival418]

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

I am modifying core templates from different providers to alter the style of thinking for my agent and control all aspects of its prompting.

Describe the solution you'd like

Override prompt templates in the character file for all prompts (twitter generation, search, interaction, etc)

Describe alternatives you've considered

Diverging (which would suck).

Merged, can add template overrides into character files
