Walkthrough

The arrow icon in the Thinking component was changed from an upward-pointing to a downward-pointing arrow in both the import and template. Additionally, the changeExpand function was refactored for more concise conditional logic, with no changes to exported or public entities.

Changes

File	Change Summary
packages/core/src/components/Thinking/...	Replaced ArrowUpBold with ArrowDownBold icon and condensed a conditional in changeExpand function.

Poem

Downward arrows now appear,
To signal change is drawing near.
A function trimmed, concise and neat,
Makes rabbit code feel quite complete.
With every tweak and tiny fix—
The codebase hops, and never sticks!

43-43: Address the linting rule conflict.

The formatting change conflicts with the ESLint rule antfu/if-newline which expects a newline after the if statement. Consider either reverting to the multi-line format or updating the linting configuration if this style is preferred.

-  if (props.disabled) return;
+  if (props.disabled)
+    return;

8-8: LGTM! Icon import updated correctly.

The change from ArrowUpBold to ArrowDownBold aligns with the PR objective to improve the expand/collapse icon accuracy.

---

129-129: Excellent UX improvement!

The icon change to ArrowDownBold properly implements the expand/collapse state indication. With the expanded CSS class (line 125), this creates intuitive behavior where:

• Collapsed state: down arrow (▼) indicates "click to expand down"
• Expanded state: rotated up arrow (▲) indicates "click to collapse up"

This directly addresses the PR objective of fixing icon direction accuracy.
