Use MASC Browser tools to read or operate Firefox/Zen tabs, inspect images, and verify requested web actions. Use for Browser Lane work and session, selector, or browser connection failures.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Browser Lane: Firefox / Zen 브라우저의 실제 상태를 읽고 요청된 작업을 수행한다. 도구가 성공했다는 사실과 사용자가 요청한 결과가 만들어졌다는 사실을 구분한다. ## TUI 관측을 이어받기 운영자가 Browser Lane의 `y`로 복사한 관측을 주면, 먼저 그 안의 `lane`·`clientId`· `tabId`·`url`과 요청을 함께 읽는다. 복사된 당시의 관측을 설명하는 요청이고 충분한 `text`가 있으면 그 시점의 자료로 답한다. 현재 상태·변경 여부·최신 내용 요청이면 복사된 text만으로 답하지 않고 같은 탭·범위를 재관측한다. 같은 탭을 다시 찾기 위해 BrowserTabs부터 반복하지 않는다. 더 읽어야 하면 전달받은 범위에서 이어간다. `documentId`·`nodeId`는 선택 요소, `scope`는 관측의 읽기 범위다. 요청 의도에 따라 고른다. | 복사된 view | 요청 | BrowserRead | |---|---|---| | content | 같은 범위 더 읽기 | mode=scene, 기존 scope 객체 유지 | | regions | 선택 영역 본문 읽기 | mode=scene, 선택 documentId/nodeId 쌍을 새 scope로 지정 | | regions | 영역 목록 갱신 | mode=regions, 기존 scope 객체 유지 | 기존 scope가 null이거나 없으면 생략한다. regions의 선택 영역 참조는 scope=null이어도 존재한다. content의 임의 텍스트·버튼을 영역 scope로 승격하지 않는다. - `expectedUrl`·`scope`·`navigationSource`는 최상위 문서의 `mode=scene` 또는 `mode=regions` 읽기에서만 지원된다. 이 읽기에서는 받은 `url`을 expectedUrl로 쓴다. text/elements/screenshot/frames/dialog/downloads 및 `framePath`로 프레임 내부를 읽을 때는 이 세 필드를 넣지 않는다. expectedUrl을 넣으면 `expectedUrl supports top-document scene or regions only`로 거절한다. 반환 스키마에 URL이 있는 관측만 받은 URL과 대조하고, 제공된 탭·문맥·범위를 확인한다. …

How to install
mdr add jeong-sik/masc/browser-lanes@sha256:6e3ea26f00a79eeeThe line at the top of this page pins the label git:20260912.08b62d1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
