PR Summary

Low Risk
Low risk UI behavior change limited to Home resource-open handling; removes an implicit sidebar toggle so layout state should no longer change unexpectedly when artifacts open.

Overview
Stops automatically collapsing the workspace sidebar when a mothership resource/artifact opens from chat.

handleResourceEvent in home.tsx now only expands the resource panel (if collapsed) and no longer reads/toggles useSidebarStore, preventing side effects on sidebar state.

Greptile Summary

This is a minimal, focused bug fix that removes the unintended side-effect of auto-collapsing the left sidebar whenever a new artifact (resource) was opened in the mothership chat panel.

Changes made:

• Removed the two-line block inside handleResourceEvent that called useSidebarStore.getState() and conditionally called toggleCollapsed() to collapse the sidebar.
• Removed the now-unused useSidebarStore import.

The remaining behavior of handleResourceEvent is preserved: if the resource panel is currently collapsed, it expands it (setIsResourceCollapsed(false)) and triggers the slide-in animation (startAnimatingIn()). The sidebar state is simply no longer touched during this flow.

Confidence Score: 5/5

• Safe to merge — the change is a clean removal of an undesired side effect with no risk of regressions.
• The diff removes exactly two lines of unintended behavior and one no-longer-needed import. The surrounding code remains functionally complete and correct. There is no new logic introduced, no shared state mismanagement, and no risk of breaking adjacent functionality.
• No files require special attention.

Important Files Changed

Filename	Overview
apps/sim/app/workspace/[workspaceId]/home/home.tsx	Removes two lines from handleResourceEvent that were collapsing the sidebar whenever an artifact opened, and cleans up the now-unused useSidebarStore import. The remaining logic (expanding the resource panel and triggering the slide-in animation) is intact and correct.
