…mplates prefillChips → promptTemplates, PrefillChip → PromptTemplate, and the template's nested starters → completions. The thing is a fill-in-the-blank prompt stem; "template" states the incomplete-by-design contract (click ≠ send) where "prefill chips" named the mechanism and the widget shape. The completions rename also removes the second meaning of "starters" (welcome starters send on click; template completions append to the draft). The API merged after 0.13.0 was published, so nothing has shipped with the old names — no consumer breaks. Internal component and DOM class names (WelcomePrefillChips, openui-agent-prefill-chip*) keep describing the chip UI itself.

WelcomeScreen.tsxasking for a better prop name — landing it now because the API merged after react-ui 0.13.0 was published, so the old names have never shipped and the rename is free. After the next release it would be a breaking change.Rename
