From delivery to training: How to turn AI programming collaboration into a Coding Mentor data closed loop

The real organizational value of AI programming assistants is not just to increase delivery speed, but to precipitate trainable, evaluable, and reusable mentor signals in every requirement disassembly, code generation, review and revision, test verification, and online review. This article reconstructs the closed-loop framework of AI training, AI-assisted product engineering delivery, high-quality SFT data precipitation, and model evaluation.

Agent Harness 3/25/2026

Agent Harness is not a supporting role, but the most underrated main battleground of AI engineering in 2026

What really determines the upper limit of an agent is often not the model itself, but the harness organized around the model. This article is based on LangChain's disassembly of the agent harness, extending my complete understanding of file systems, code execution, context management, verification closed loops and long-term task endurance. It also explains why the focus of AI engineering competition in 2026 is shifting from 'model capabilities' to 'working system design'.
