 """
 Example: langchain_messages() against a Claude model with extended thinking turned on.
 
-With thinking on, Anthropic returns ``content`` as a list of blocks — a ``thinking`` block followed
-by a ``text`` block — instead of a plain string. A handler that only reads string content reports
-an empty response for these runs while the tokens are still spent, so this example fails loudly
-when no text comes back.
+Point this at a flag whose ``model.parameters`` enable thinking (and whose ``max_tokens``
+exceeds the thinking budget). Anthropic then returns ``content`` as a list of blocks — a
+``thinking`` block followed by a ``text`` block — instead of a plain string. A handler that
+only reads string content reports an empty response for these runs while the tokens are still
+spent, so this example fails loudly when no text comes back.
 
 Anthropic omits thinking from the turn that follows a tool result, so give this a prompt the model
 can answer on its own — a run that goes through the tool loop ends on a plain string and never
