What
When you resume a session, Claude Code reads through its saved transcript. It now records about 15 more measurements of that scan, such as how many rows it read and how many bytes it went through. A separate report, made when idle tool uses are cleared, now also counts tool uses since you returned.
Why
This gives more detail for measuring how fast sessions resume.
