Teaching Coding Agents to do Spreadsheets - Nuno Campos, Witan Labs

Summary

The main theme is training coding agents to effectively master spreadsheets, a task more challenging than expected due to their visual and inferential nature. Key subjects include breaking down tasks into agents, comparing different architectures, and the evolution of accuracy from 50% to 92% on a financial analysis benchmark. The practical takeaway is that while initial approaches like multi-agent systems can seem promising for error reduction, rigid architectures and context flow limitations can lead to dead ends, emphasizing the need for adaptable and context-aware solutions.
