What
Three built-in tools now come with a short note telling the model when to use them:
The task checklist tool, which tracks the steps of a task
The worktree tool, which works with separate working copies of a project
The plan-mode exit tool, which ends plan mode
For example, the plan-mode exit tool's note says that when Claude is in plan mode, the plan is ready, and it is about to ask whether to proceed, it should use this tool rather than asking a question.
Why
These notes may change when Claude reaches for these tools, such as finishing a plan with the plan-mode exit tool instead of asking you in plain text.
