Unclear What the 'reading budget' controls or limits is not stated in the finding.
What
Hooks (custom scripts that can run at points in Claude Code's workflow) are invoked with a new budget accessor available to their execution context, both in normal runs and in .catch error handlers. Separately, Claude Code now detects when a hook produced no downstream calls at all (and wasn't an error handler or a 'hop' handler) and records timing information for that case.
Why
This is internal bookkeeping that gives Claude Code more visibility into hook behavior, particularly hooks that run but never pass control onward, without changing what a hook author needs to do.
