美中实验室论文提出 AgentBug-Smith，将智能体框架 bug 转为可运行测试

Self-improving AI agents will need to fix their own code. And this paper from top US+China labs, shows coding agents miss most such bugs but improve with lessons from past fixes. that real bugs in agent harnesses, can be automatically turned into a growing set of runnable tests. An agent's own code is everything around the model: tool calls, memory, and prompts. Its bugs depend on live model calls, which makes them hard to recreate and test. So the researchers built AgentBug-Smith, which turns real GitHub bug reports into runnable tests. The result is a 200-bug benchmark that keeps growing. The best of 3 coding agents fixed just 9% of those bugs, versus about 40% reported on regular software bugs. A short guide of lessons from past fixes lifted an agent from 1 to 6 correct fixes on 79 unseen bugs. Before trusting a coding agent with your agent's code, try it on bugs you've already fixed.
