**Category:** improvement
**User Impact:** Users can create, discover, and import agents from one
consistent Add agent dialog.
**Problem:** Agent creation, discovery, and import were split across a
dropdown and separate dialogs, making the Add agent flow fragmented. The
existing E2E suite also continued targeting the deleted dropdown after
the flows were unified.
**Solution:** Route the new-agent card directly into a unified dialog
with dedicated Create, catalog, and Import navigation, then update the
affected E2E coverage to exercise that interface and its current empty
state.
