Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.02080 |
| Opus 5 | $0.00000 | $0.01040 |
| Sonnet 5 | $0.00000 | $0.00416 |
| Haiku 4.5 | $0.00000 | $0.00208 |
Grade A, and why
b3os-mac-app-shell scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
b3os-mac-app-shell
웹앱을 Apple 네이티브 셸(.app)로 래핑하는 팀 표준 레시피. 별도 골격 저장소를 참조하며 코드를 복제하지 않는다 — 이 스킬은 "언제·어떻게·무엇을 조심"의 운영 지식이고, 실제 구현·빌드 스크립트는 골격에 있다.
★선행 조건 — 골격 저장소는 이 저장소에 들어있지 않다.★ 정본 골격은 b3rys 내부 비공개 저장소
mac-iphone-shell(SwiftUI multi-platform 라이브러리 + HostApp 패턴)이다. 접근 권한이 있는 팀원이 따로 clone해야 하고, 아래 절차와 references의 경로는 본인이 clone한 위치를 가리킨다(이 문서에서는$SHELL_SKELETON으로 쓴다). 접근 권한이 없으면 이 스킬의 빌드 절차는 실행할 수 없다 — "검증된 함정"·"검증 절차" 절의 운영 지식만 참고 자료로 쓴다.owner / 업데이트 책임자: agent A, developer (둘이 함께 유지·리뷰)
언제 쓰는가
- 이미 있는 웹 대시보드/웹툴을 설치 가능한 Mac 앱(.app) 으로 내보내고 싶을 때 (예: b3os 대시보드 →
b3os.app) - "맥앱으로 래핑한 티 안 나게, 라이트/다크 seamless, 창이 네이티브처럼" 요구
- iPhone 동반 앱(같은 골격, read-only/동일 셸)도 필요할 때
- ❌ 쓰지 않는 경우: 네이티브 UI가 본질인 앱(웹뷰가 아니라 SwiftUI 화면이 주). 그건 골격 없이 일반 SwiftUI로.
전제 · 요구사항 (이게 없으면 이 스킬은 못 쓴다)
- macOS Sonoma 14+ (골격 deployment target). Xcode 16.2+ (
xcodebuild -version). Swift toolchain 포함. - 배포(외부 공개)하려면 Apple Developer 계정 + Developer ID Application 인증서. 로컬/팀 테스트는 ad-hoc만으로 가능(서명 안 됨).
- 이 스킬은 macOS 빌드 환경 전용 — Windows/Linux에선
.app빌드 불가(셸 컨셉만 참고). - 핀(검증된 조합): macOS 14 / Xcode 16.2 / 골격
mac-iphone-shell최신 main. 더 높은 버전은 빌드 후 §검증 통과 시 사용.
입력값 (앱마다 정하는 것)
| 값 | 무엇 | 어디서 설정 |
|---|---|---|
| webURL | 셸이 로드할 웹 주소 | AppShellSettings.defaultWebURL (기본 http://localhost:7878/team) + 런타임 UserDefaults 키 AppShell.webURL로 덮어쓰기 가능 |
| app name | .app 표시 이름 |
골격의 $SHELL_SKELETON/scripts/package-macos-app.sh의 APP_NAME (예: b3os.app) / Xcode HostApp 프로젝트명 |
| product name | 빌드 산출 바이너리 | 같은 스크립트 PRODUCT_NAME (예: B3rysMacApp) |
| bundle id | 번들 식별자 | Xcode HostApp 프로젝트 (Signing & Capabilities) |
| WKAppBoundDomains | 셸이 이동 가능한 도메인 화이트리스트 | HostApp Info.plist (보안: limitsNavigationsToAppBoundDomains=true와 한 세트) |
절차 (요약 — 상세는 골격 저장소의 docs/QuickStart.md "30분")
- 골격 라이브러리 가져오기 — 내부 비공개 저장소를
$SHELL_SKELETON으로 clone하거나 SPM 의존성으로 추가 - Xcode에서 App 프로젝트(HostApp) 생성 → AppShell 라이브러리 추가
- App entry를
AppShellRootView(셸)로 교체,webURL·환경 주입 Info.plist:WKAppBoundDomains+ 환경 도메인 설정- Capabilities (서명용 — Apple Developer 계정)
- 빌드·실행:
swift build/ Xcode Run - 배포용
.app패키징:$SHELL_SKELETON/scripts/package-macos-app.sh→.build/<APP_NAME>(테스트=ad-hoc 서명, 배포=notarize)
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

b3os-mac-app-shell is a skill published in the GitHub repository b3rys/b3rys-team-os (12 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 2,080 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
