“It’s the Architecture, Stupid” — Why Prompt Engineering Won’t Fix Agents

Sounds like you’ve gone deep — persistence, token efficiency over time, and autonomous end-to-end execution are all hard problems, so respect for tackling the full stack. A few of those resonate directly with what ORCA addresses: persistence of cognitive state, modular composition, and reducing redundant computation across sessions. We may be solving overlapping problems from different angles. Is your project open source? or do you have a link for me to check? I would be intrested in comparing approaches and see if they fit or if they are compatible.
