Agent harness or deterministic routing? Reddit debates the right AI architecture for SaaS
Odd_Phone_5660 · reddit · 2026-11-14
A Reddit user asks for honest, personal takes on whether SaaS systems should be built as an agent harness (orchestrating agents that talk to each other to execute actions) or as a deterministic routing system that uses AI only for specific inner steps. The poster explicitly rejects the "it depends on the use case" answer and wants a concrete bet. The thread frames a core agent-engineering trade-off between controllability/debuggability and flexibility.
