AGENTS.md 反过度设计：不为理论风险扩复杂度
Dave Kiss 点赞 opencode 的 AGENTS.md 规则：加复杂度前先讲清失败模式与成本，征得用户同意。
This is such a banger rule in @opencode's AGENTS.md "Before adding complexity for a speculative or vanishingly unlikely race or security edge case, explain the concrete failure mode, likelihood, and complexity cost to the user and get their buy-in. Do not silently expand scope for theoretical robustness."
