+- AX Agent 채팅/코워크/코드 공통 입력창 우측 상단의 `프리셋` 선택 버튼을 제거해 composer 상단을 더 단순하게 정리했습니다.
+- 파일 첨부 버튼을 기존보다 약 1.5배 키우고, 전송 버튼도 같은 기준의 정사각 크기로 맞췄습니다. 두 버튼의 아이콘은 모두 상하좌우 중앙 정렬로 보정했습니다.

 - AX Agent 사용자 메시지 하단 메타 행 레이아웃을 정리해, 시간 표시와 복사/편집 액션 버튼이 같은 위치에 겹쳐 보이던 문제를 수정했습니다.
 - 사용자 메시지 하단 바는 이제 전용 컬럼을 나눠 시간과 액션이 항상 분리되어 보이며, hover 상태와 무관하게 메타 행이 안정적으로 유지됩니다.

 # AX Copilot - 媛쒕컻 臾몄꽌
 
+- Document update: 2026-04-06 15:12 (KST) - Simplified the shared AX Agent composer by removing the top-right preset selector from Chat/Cowork/Code. Increased the attach button by roughly 1.5x, matched the send button to the same square footprint, and re-centered both icons for a cleaner balanced action row.
 - Document update: 2026-04-06 15:04 (KST) - Fixed the AX Agent user-message footer row overlap. Sent-time metadata and copy/edit actions no longer share the same overlay cell and now render in dedicated columns so hover actions cannot collide with the timestamp.
 - Document update: 2026-04-06 09:27 (KST) - Re-framed the remaining `claw-code` parity work into three explicit tracks: user-facing UI/UX quality, LLM/task-handling quality, and maintainability/extensibility structure. This separates visible polish from runtime truth and from architectural cleanup.
 - Document update: 2026-04-06 09:27 (KST) - Captured the new track plan in `docs/claw-code-parity-plan.md` with reference files, AX apply targets, completion criteria, quality criteria, and recommended execution order so future work can be prioritized more deliberately.
