What
A hook is a script you set up to run at certain points while Claude Code works. When an agent's run is resumed, a hook can only refuse that run. Claude Code now tells you when other fields a hook returned were ignored for this reason.
Why
If you write hooks, you get an explicit explanation instead of your fields being silently dropped.
