I think the real value here isn’t “planning vs not planning,” it’s forcing the model to surface its assumptions before they harden into code.
LLMs don’t usually fail at syntax. They fail at invisible assumptions about architecture, constraints, invariants, etc. A written plan becomes a debugging surface for those assumptions.
