detection for Gemini grounding responses with citations - Prevent consecutive mistake count increment when grounding is used - Fix infinite loop issue when Gemini provides search results - Add comprehensive test coverage for grounding detection Fixes #6503 --- src/core/task/Task.ts | 16 +- .../__tests__/Task.gemini-grounding.spec.ts | 248 ++++++++++++++++++ 2 files changed, 263
