I'm a Computer Science master's student at the University of Hong Kong, currently interning at Ant Group. I previously interned at Cybopal and Kuaishou. I'm interested in building and evaluating AI agents, particularly agent harnesses, tool use, and how agents can improve through feedback. I also build open-source projects and contribute to projects I find interesting.

 Compare agent Skills, rules, and MCP setups with paired A/B tests. Track task quality, trigger behavior, and token cost with replayable results and budget controls. Available on npm. |
 A testbed for evaluating agents on Chinese tool-use tasks where actions change the environment. It simulates state and failures, grades both outcomes and action sequences, and explores small-model training and execution. |
