Do you work with text data for your job or research? We’d love to talk to you!. We're running a paid user study at CMU to understand how people explore and visualize text data while programming—and to gather feedback on our new open-source visualization tool. Details below 👇.

AGDebugger is built on top of the awesome #AutoGen agent framework and this research was done while I was at Microsoft Research this past summer alongside @bansalg_ , @vykthur, @adamfourney, @jack_gerrits, @ekzhu, and @SaleemaAmershi.

Results from our user study reveal how developers leverage AGDebugger to make sense of agent behavior and modify agent messages to steer them towards different outcomes.

Introducing AGDebugger—a new interactive tool that enables developers to send new instructions to agents, step through each agent response, and reset agents to earlier points in a workflow after a failure.

Excited to share our #CHI2025 paper: "Interactive Debugging and Steering of Multi-Agent AI Systems"!. As 🤖 AI agent teams 🤖 powered by LLMs take on complex tasks, debugging and steering these agents becomes crucial. How can developers better understand AI agent behavior?

AutoProfiler lets you explore the distribution of each column, number of nulls, and summary statistics all without having to write extra code. You can even export the profiling charts as altair code for further editing!. See more at our github repo:
