What happened
Weaviate's developers used Patronus AI's Percival to debug and optimize an orchestrating AI agent that coordinates a query agent and a transformation agent, including long-running asynchronous data transformations. Percival analyzed agent traces and suggested prompt fixes for task ambiguity and tool-usage confusion.
Summary written by usedby from the source page, in English. The figures are those of Patronus AI and Weaviate, not ours.
The "Generate Insights" feature in Percival allowed the team to quickly understand complex agent traces that would have otherwise required hours of manual log analysis.
It is an extremely helpful and interesting tool for building Agent systems. I think the best compliment that I can give as a developer is that this really made me feel empowered to test out a new idea.
