I've recently adoped pi at work and its been a treat. I think just starting with the base agent and installing (or creating) plugins as the need arises is best. If you really want some plugins to start with pi-subagents and the rpiv collection are what I'd recommend.
Thanks - I think I more need to work on the prompting.. possibly. IIRC I was struggling with local operations as basic as finding files/reading files/correlating classes in the same folder.
