# Binding-Constraint Thesis
|
||
|
||
> Agent 在真实世界中的可靠性瓶颈不在模型本身，而在包裹模型的基础设施——Agent Execution Harness。基础设施质量，而非模型能力，设定了 Agent 可靠性的天花板。
|
||
|
||
## 三大证据链
|
||
|
||
1. **工程演进证据**：从 Prompt → Context → Harness Engineering 的三阶段演进表明，约束瓶颈随工程成熟度逐步上移
|
||
2. **跨层综合证据**：[[cost-quality-speed-trilemma]]、[[capability-control-tradeoff]]、[[harness-coupling-problem]] 三者都无法在单层内解决
|
||
3. **开放问题证据**：五大开放问题的核心都是 harness 层面而非模型层面的问题
|
||
|
||
## 关键实验
|
||
|
||
- Bölük (2026a)：仅改变 harness 格式（不改变模型），15 个 LLM 的编程能力同时提升
|
||
- Anthropic (2026a)：基础设施设置在可测量地改变 benchmark 分数
