Smart agents that know when to think hard versus react fast

Game-playing agents need to balance expensive reasoning with quick reactions across thousands of steps. SPIKE splits control into two: a Strategic Controller that plans and analyzes failures, and a Reactive Controller that executes fast under strict token limits. An Event Trigger watches for failures, progress stalls, and repeated actions to decide when reasoning is worth the cost. On StarDojo, this cuts token consumption by 55% while improving success rates by 38.5% relative to baselines.
