I have been using Pi most of this year. Just one problem that's going to make me move to deepseek harness: no subagent support. I am using tintinweb/pi-subagents and it works, but always wondering if there is a better option. It doesn't seem to work right with Herdr's agent status.
I have a plugin for rotating between providers as quota gets used up by altering the model used by the tintiweb subagents. https://github.com/gregwebs/pi-quota-dispatcher
