0.1.15

Introducing Debug Mode, an interactive debugging feature that lets you pause LLM requests before they're sent to the model. With debug mode enabled, you can inspect the full request payload, edit messages, parameters, and tool schemas in real time, then continue execution with your modifications—all without changing your application code.

Debug Mode in action

Debug mode is perfect for debugging agent prompts, verifying model selection, inspecting tool schemas, and tuning parameters on the fly. Simply enable the breakpoint toggle in the Traces view, and every outgoing LLM request will pause for inspection and editing.

With debug mode you can:

  • Inspect the model, messages, parameters, and tool schemas
  • Continue with the original request
  • Modify the request and send your edited version instead

Learn more in the Debug Mode documentation.
