Description
An agent step that came back with no tool call and no text failed the whole message with
empty_content, even when the answer had already been written in an earlier step — the check only looked at the text streamed in the current step. It now checks the answer accumulated on the agent message, and when there is genuinely nothing anywhere it re-runs the step once with tool use disabled to force a final answer before erroring.Tests
Existing agent-loop unit tests pass; validated against a production trace where the answer was written in step 1 and step 2 came back empty.
Risk
Low — the forced re-call only happens on a step that would otherwise have failed.
