- The configuration panel reads as two labelled sections instead of two anonymous three-column
grids. Connection holds Model, API Key, Base URL and Extra Headers; Generation holds
Thinking Level, Thinking Summary, Tool Choice, Trace ID, and then System Prompt and Tools across
two columns each. Both sections share one
1 / 2 / 4column grid, so each row fills out rather than trailing off. start_playground_server/startPlaygroundServerdefaultAGENTHUB_DEBUGto1. The playground exists to show what a model and its endpoint actually send, so unknown stream output raises there instead of being skipped; anAGENTHUB_DEBUGalready in the environment still wins.
