Unclear It is not clear when Claude Code makes this hold, so whether it affects a given session is unknown.
What
The prompt cache is a stored copy of the earlier part of a conversation, so the model does not have to process it all again on every turn. Claude Code can hold a request that keeps this cache warm. That hold now has two limits:
- A floor, a minimum age the hold must reach.
- A maximum age, past which the hold is reported as too old.
Before, only a too-young check against a fixed value and a cap on the hold existed. A turn whose report ended as done skips both new limits.
Why
It adjusts how long Claude Code holds a cache-warming request.
