\begin{chatuser}
Find the repo's largest file and check the weather API.
\end{chatuser}

\begin{chatthinking}[Reasoning][paragraph]
This reasoning trace uses paragraph mode instead of stepped bullets: it
reads as ordinary upright prose, which is easier to skim for a longer
chain of thought than italic arrow-prefixed steps. The user can choose
whichever mode fits the length and style of a given trace.
