What
In auto mode, a classifier (a separate check) reviews Claude's actions against your permission rules. Those rules now pass through a size limit before they reach the check. When rules are dropped to fit, Claude Code records how many allow, deny and ask rules were dropped.
Why
If you have a lot of permission rules, the auto mode check may not see all of them.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
Whether rules were already being dropped before, or only the record of it is new, is not settled.
