From a9174a8bb45cf302a2af773504d3716018dfa435 Mon Sep 17 00:00:00 2001 From: Roo Code Date: Tue, 29 Jul 2025 17:19:38 +0000 Subject: [PATCH] fix: integrate Gemini grounding sources into assistant message - Modified streaming logic to append grounding sources to the last text chunk instead of yielding as separate message - Added tracking of content yielding to ensure sources only appear when content exists - Added comprehensive test coverage for grounding functionality including edge cases - Fixes issue where grounding sources appeared as separate message bubbles Fixes #6372 ---
