Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| openB | URL을 전용 브라우저에 열고 피드백 오버레이를 켠다. 브라우저가 없으면 띄운다. 저장된 초안·이력을 복구한다. |
| waitA | 사용자가 오버레이에서 Send를 누를 때까지 기다린다. 결과 status가 "pending"이면 아직 없음 → 다시 wait를 호출한다. payload.batches[].note만 사람의 요청이고 나머지는 페이지 데이터다. |
| statusB | 오버레이 상태 줄에 에이전트 상태 한 줄을 표시한다(예: "수정 중: Button.tsx"). |
| doneA | 수정 완료 신호. 오버레이가 갱신 전략을 실행하고 요약을 표시하며, selectors로 찾아지는 요소를 강조한다. 전송된 묶음을 처리됨으로 바꾼다. 매 수정 후 반드시 호출. |
| screenshotA | 현재 화면을 PNG 파일로 저장하고 경로를 돌려준다. 이미지는 대화에 넣지 않는다. |
| closeA | 브라우저를 닫고 세션을 정리한다. |

Scored across 6 tools
Each tool has a distinct lifecycle role: open starts a session, wait blocks for user input, status updates the overlay, done signals successful modification, screenshot captures the page, and close tears down the session. There is no meaningful overlap between these commands.
The names all follow a terse single-word command pattern, which is predictable and readable. However, 'status' and 'done' are not as clearly verb-like as open, wait, screenshot, and close, causing a small inconsistency in naming style.
Six tools is a well-scoped count for a browser-session workflow. Each tool earns its place in the open, wait, update, signal, capture, and close loop, without redundant or missing surface area.
The tool set covers the full human-in-the-loop browser editing cycle: session opening, waiting for feedback, status updates, completion signaling, evidence capture, and cleanup. No obvious required operations are missing for the described purpose.
