[RavenclawDev 253] Re: checking if an agent has been restarted

[Antoine Raux]

Udhay (and everyone),

The difference is that the custom StartOver function gets called by the
StartOver library agent, i.e. anytime a user says "START OVER" or something
equivalent. To get the same behavior "manually", you'd have to create an
agent that gets triggered on such user input, i.e. you'd have to duplicate
the generic StartOver library agent. It's precisely in an attempt to keep
the StartOver behavior as generic (i.e. task-independent and reusable) as
possible that we designed this customizable StartOver function thing.

Hope this clarifies things...

A small clarification.

What is the difference between reopening all the agents except Welcome
prompt at the end and the method you just described?
