@xsser_w: Lu Qi is still amazing. A year ago he told me to work on sandbox/container security, and I didn't realize what he meant. Now looking back... I was so stupid. He had many far-sighted ideas, many of which have been validated now. Damn. Looking at it now, the core of making a harness is sandbox and validation. In the sandbox, you can see all trajectories and boundary explorations.
Summary
The author praises Lu Qi for his insights on sandbox/container security from a year ago, which have since been validated, emphasizing the core role of sandboxes in observing reward hacking.

Lu Qi is still too brilliant. A year ago, he told me to work on sandbox/container security, and I didn’t grasp what he meant. Now looking back… I was such an idiot 😀. He had so much foresight, and much of it is now validated. Good grief 😀.
Looking at it now, the core of building a harness is sandboxing and verification. Inside the sandbox, you can see every trace and boundary probe, and observe the entire reward hacking process.

@vintcessun: What troubles security teams most is too many false positives in the vulnerability discovery process and lack of closed-loop fix verification. Anthropic's reference implementation directly breaks the entire process into an auditable seven-stage pipeline. The core design is not about stacking features, but building a verification chain—each finding must go through independent sandbox reproduction, deduplication, scoring, and finally the patch must also pass regression testing...
Anthropic has released an open-source reference implementation for vulnerability discovery and remediation, building a verification chain with a seven-stage pipeline based on Claude, aimed at reducing false positives and ensuring closed-loop fix verification.

Using Pi Durable as a starting point, the article breaks down the evolution of the Agent Harness architecture: decoupling the persistence system, agent loop, and execution environment to enable lossless state recovery, codemode tool calls, and server/client separation. It also proposes a scalable architecture for a long-running Harness, with the goal of reducing hardware resource consumption by an order of magnitude.
