+- 메시지 내부 액션 바와 Cowork/Code 실행 배너를 더 `claw-code`처럼 보조 레이어로 낮췄습니다. 메시지 액션은 텍스트 버튼 대신 작은 아이콘 버튼 중심으로 바꾸고, 실행 배너는 여백·폰트·토큰 배지·파일 경로 표시를 한 단계 더 얇게 줄여 본문보다 덜 튀게 정리했습니다.

 - `document_plan` 후속 실행 분기를 `claw-code` 기준으로 다시 보강했습니다. 이제 문서 플래너 출력에서 body 골격과 즉시 실행 지시를 깨진 문자열 비교에 의존하지 않고 안정적으로 추출해, `html_create / document_assemble / docx_create / markdown_create` 후속 호출 유도가 실제로 이어집니다.
 - 코워크 문서형 작업은 설정이 `planMode=off`여도 내부적으로 `always` 플랜 경로를 타도록 보정했습니다. 그래서 문서/보고서/제안서 요청은 먼저 계획을 세우고, 그 계획을 바탕으로 실제 문서 생성 단계까지 이어가도록 정리했습니다.

 - Document update: 2026-04-05 16:55 (KST) - Simplified AX Agent message rows and sidebar conversation items toward the `claw-code` reading model. Message bubbles now use tighter padding/radius/meta text, and conversation rows now prefer lightweight running/failure summary text over heavier success/failure badge cards.
 - Document update: 2026-04-05 17:03 (KST) - Reworked the AX Agent UI skeleton further toward `claw-code`: sidebar width and row heights were tightened, the collapsed icon rail and sidebar header were flattened, status strips were reduced, and the composer shell/input chrome was made slimmer and less card-like.
 - Document update: 2026-04-05 17:03 (KST) - Re-tuned responsive width calculation for the new shell so the message axis now scales up to `880` and the composer up to `820`, keeping both aligned on the same center line as the window narrows or expands.
+- Document update: 2026-04-05 17:12 (KST) - Reduced message action chrome and event-banner density further toward `claw-code`. Message actions now use compact icon-only buttons, and Cowork/Code event banners use tighter margins, smaller metadata, and lighter file-path summaries so execution status stays subordinate to the main transcript.
 - Document update: 2026-04-05 16:02 (KST) - Fixed the Cowork document execution handoff around `document_plan`. The loop no longer depends on broken localized marker strings to detect the scaffold/body block or the immediate-next-step hint; it now extracts body markers robustly and resolves the correct follow-up tool (`html_create`, `document_assemble`, `docx_create`, `markdown_create`) before re-prompting the model.
 - Document update: 2026-04-05 16:02 (KST) - Added `ResolveEffectivePlanMode(...)` so Cowork document/content tasks automatically use the `always` plan path even when the persisted plan mode is `off`. This brings Cowork closer to the `claw-code` expectation of plan-first execution for document-heavy work.
 - Document update: 2026-04-05 16:02 (KST) - Strengthened `BuildCoworkSystemPrompt()` so document/report/proposal/manual requests must produce an execution plan first and are not considered complete until a real output file path has been created or updated.
