Newbie here: how much of creating agents are portable from one AI platform to another? Do they mostly have the same concepts but differ slightly in implementation? Or something else?
Most agent frameworks implement a ReAct (Reflect->Act) pattern in the form of a loop that "reasons" until a "final_answer" has been found.
Most framworks also implement some form of session cache (scratchpad), tool use, and thought logging/tracing.
While most implementations are similar they are not easily transferable.
