## What the story says

Snorkel AI uses Portkey to trace and debug its multi-agent evaluation systems that validate expert-generated labels. Portkey shows every agent, sub-agent, and tool call as a nested tree, and lets the team compare good and bad traces side by side.

Summary written by usedby from the source page, in English. The figures are those of Portkey and Snorkel AI, not ours.

> With Portkey, the team could finally see what was happening inside their agents. Every call, every sub-agent, every tool invocation appeared as a nested tree, no more reconstructing execution paths from scattered logs.

- **20%**: “20% accuracy boost in agent evaluations by catching and fixing edge cases that were previously invisible in aggregate metrics.”

> Prior to Portkey, Snorkel debugged LLM applications with a fragmented patchwork of logs in s3, DB queries, and manual visualization. The clean Portkey UI allows us to identify, debug, and rebuild agents with confidence.

> With Portkey, every agent, sub-agent, and tool call is visible in one hierarchy — you can see how decisions branch and converge. Seeing the full execution tree in one view completely changed how we debug
