Under the hood
No user-facing change: this was a variable rename only, not a wording change
What
This update touched the code behind the Design tool's write-denial message, but only renamed an internal variable. The message itself, which explains what to do when writing without a plan_token in plan mode, reads exactly as it did before.
Why
Nothing changes for anyone using Claude Code here; the underlying refusal behavior and its explanation stay the same as previously described.
