You'll notice
Checking your usage limit can now be answered from a recent cached value instead of a network request
What
Before checking how much of your usage limit you've used, Claude Code now first looks at a recently cached local snapshot. If that snapshot is less than 60 seconds old and no newer usage information has come in since, it answers from that cached value and skips calling the server entirely, logging a message noting how old the snapshot was.
Why
This avoids unnecessary network requests when the usage information is already known to be fresh, making usage checks faster and lighter without affecting accuracy.
