Tool

A disclosure for what the model is doing — a tool call or a step of reasoning. The row is telemetry, not a key: a quiet debossed strip with a status chip; the result opens in the well below. Reasoning is the same shape for chain-of-thought.

Found 3 matches for “spring config”.

Notes

status is one of pending, running, done, or error — it maps onto the AI SDK's tool-part states without depending on them.
Expanding eases the panel height (the one thing seamui animates with a duration, like opacity) and snaps instantly under reduced motion; the status Spinner carries its own reduced-motion pulse.
The trigger presses with depth.pressed — dogfooded via buttonVariants and a motion render, since Collapsible owns the trigger's ref.
Built on Base UI Collapsible: the trigger exposes aria-expanded and the panel is properly associated. The status chip is a polite live region, so a state change is announced without re-reading the whole row.

Press feedback, reduced motion, and haptics follow the global policy — see Motion and Haptics.
