I study how coding agents can be trained, evaluated, and trusted on real software projects.

Alan Zeng

I’m a second-year M.S. student in Computer Science at Fudan University, working on LLMs for code and AI for software engineering.

I’m interested in how coding agents can be trained, evaluated, and trusted on real software projects. That means going beyond passing tests: respecting a project’s design constraints, and learning from the design knowledge buried in code review history.

Outside research I build small developer tools and AI-powered utilities for my own workflow. Most of them are on GitHub.

Passingthetestsisnotthewholestory.

Coding agents now resolve real issues, and we mostly judge them by whether the tests pass. My research measures what pass rates miss: whether a patch respects the design of the project it lands in.

    Does Pass Rate Tell the Whole Story? Evaluating Design Constraint Compliance in LLM-based Issue Resolution

    Kai Yu, Zhenhao Zhou, Junhao Zeng, Ying Wang, Xueying Du, Zhiqiang Yuan, Junwei Liu, Ziyu Zhou, Yujia Wang, Chong Wang*, Xin Peng*

    SWE-Shield, a benchmark for whether agent patches respect a project’s design constraints. Test pass rates substantially overestimate patch quality.
