Across 2,700 runs with Kimi K3 at three thinking-effort levels, stripping a full specification down to a user story increased token spend by 29.7%, while no prompt change affected run-to-run variance at all (arXiv 2608.25399). Sensitivity is strongly task-dependent, ranging 13% to 115%, so the payoff from writing a fuller spec swings by an order of magnitude across a backlog. The authors fit a predictor that prices the whole distribution of spec styles and effort settings for an unseen task from a single cheap probe, landing within 36%.
