What
Two tools now carry a short whenToUse hint for Claude:
The plan-approval tool: use it, rather than starting on edits, when about to write code for a task that is not simple, so you approve the approach first.
The list-secrets tool: it returns only ids, labels, dates and status, never secret values.
Why
When tools are not all shown to Claude up front and it has to search for them, these hints help it pick the right one. In practice Claude is more likely to ask you to approve a plan before larger changes.
