Bring Your Coding Agent: Let’s Live Submit a PR to Zed Editor

Opening a large open source project can be intimidating: an unfamiliar repository, thousands of lines of code, and a web of dependencies are often enough to drain away the initial excitement.

In this session, I will bring a Coding Agent into the Zed Editor codebase and show, from scratch, how to understand the problem, investigate a bug, trace the surrounding logic, propose a fix, and work all the way toward submitting a Pull Request live on stage. Rather than showing only polished success cases, I will present the process as it actually happens: how to explore an unfamiliar project, how to collaborate with AI to narrow down clues, how to judge whether its reasoning is trustworthy, and how to steer it back when it goes off track.

If you have ever wanted to contribute to open source but did not know where to start, or if you are curious about how AI coding tools perform in real, messy, and unpredictable engineering environments, this talk will offer an unfiltered look at the process and a practical workflow you can take home and apply immediately.
