Agent Efficiency Is Token Efficiency: Good Test Suites Cut Costly Rework, Say XState Author
DavidKPiano · x · 2026-10-08
poteto frames agent engineering as a token-efficiency problem: agents that can't verify their own work produce bugs and rework, which costs more tokens and upsets customers.
DavidKPiano adds that time-to-result can be improved deterministically: invest in a high-quality test suite, or use libraries like XState and EffectTS to enforce business-logic invariants. His key point: your codebase is a form of memory and an input to agents.
