Unclear It is not clear who can use this toolkit, for example plugins or generated artifacts.
What
Claude Code includes a small toolkit for building interface pieces with JSX, a way of writing layouts that looks like HTML. Its Button now accepts a variant option set to "primary" or "secondary". Any other value is rejected with an error, and the error message listing a Button's allowed options now includes variant.
Why
This matters to anyone writing custom interface pieces with this toolkit: buttons can now be marked as the main action or a secondary one, and a misspelled variant fails loudly rather than being ignored.
