Under the hood
Prompt suggestions can now reuse a precomputed 'turn brief' instead of always making a fresh model call
What
When generating a suggested next prompt in SDK or print mode, Claude Code now first checks for a precomputed 'turn brief' - a short summary produced as part of a turn's post-turn classification. If that precomputed brief matches the current turn, it's used directly as the suggestion instead of triggering a new generation request to the model.
Why
This can make prompt suggestions appear faster and avoids an extra model call when a suitable summary is already available.
