What
Claude Code keeps a saved copy of the list of tools available to the model. Its internal per-turn measurements now record how often that list is rebuilt only because it reached an age limit, along with what that limit is.
Why
The saved tool list now has an age limit, so it is periodically rebuilt rather than reused indefinitely. Nothing changes in what you do.
