What
When Claude Code replaces certain words coming from a hook (a user command that runs at set points), it adds a message to the output. Previously that message was one of two. It now depends on the tool involved:
One specific tool gets its own message.
The plan-approval tool gets its own message.
Tools in a particular group get another message.
All other tools get a default message.
Why
The model gets guidance text that is more specific to the tool in use.
