Judgment Labs opens general access to its tooling for improving AI agents from their traces

Judgment Labs opened for general access on October 27, according to a post on X by the account alexshander03. The post argues that long-running agent systems will produce more trace data than can currently be processed, and that the traces record what users ask for and where agents stumble.

TestingCatalog, relaying the launch, describes it as a "continuous-improvement stack" for AI agents: agent swarms go through production traces to spot failures, triage them and test fixes, and a Judgment MCP is said to work with Claude, Codex, Cursor or any MCP client. It also says users can start an investigation from Slack when an agent misbehaves or users complain. These details are TestingCatalog's reading, not the launch post's.
