T5-R5 in five minutes
ReAct interleaves a written reason and an action.
The paper is Yao and co-authors, 2022.
The reason is not automatically true. It is text.
The action still goes through your tool and your cap.
You can store the reason in the trace so a reviewer can see it.
A reason that says 'the note contains a date' must be checked against the note. The sentence is not the check.
