Title
Agentic Debugging using Time Travel
Abstract
Everyone knows that debugging the code is twice as hard as writing it. A person can’t be a great programmer without being great at debugging, and neither can an AI coding agent. Time travel debugging is a technique that has grown in both capabilities and popularity recently (Undo, rr, Microsoft’s TTD among others). This talk includes:
- Demos of what it is and how it can work for you.
- Details some of how this apparently magic technology actually is implemented (including the different approaches).
- How the technology can make AI much better at debugging: whether debugging code written by AI or pre-existing code.
