What it costs to keep this loaded
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 | $0.00097 | $0.01626 |
| Opus 5 | $0.00048 | $0.00813 |
| Sonnet 5 | $0.00019 | $0.00325 |
| Haiku 4.5 | $0.00010 | $0.00163 |
Grade A, and why
google-calendar 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 8d 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.

Google Calendar — gogcli 기반 일정 조회/생성/관리
gogcli(gog) CLI를 사용하여 Google Calendar 일정을 조회, 검색, 생성, 수정, 삭제한다.
디렉토리 구조
google-calendar/
├── SKILL.md
└── references/
└── gog-calendar-commands.md # 주요 명령어 레퍼런스
스크립트 없이 gog CLI를 직접 실행한다.
플로우
1. gogcli 설치 확인
which gog
명령이 실패하면 사용자에게 설치를 안내한다:
gogcli 설치 안내
brew install gogcli설치 완료 후 다시 시도해주세요.
설치가 확인되면 다음 단계로 진행한다.
2. 인증 확인
gog auth list
계정이 없으면 OAuth 설정을 안내한다:
Google Calendar 인증 설정 가이드
- Google Cloud Console에서 프로젝트 생성
- Google Calendar API 활성화
- OAuth 동의 화면 설정 → 테스트 사용자 추가
- OAuth 클라이언트 생성 → "Desktop app" → JSON 다운로드
- 터미널에서 아래 명령 실행:
gog auth credentials ~/Downloads/client_secret_....json gog auth add <[email protected]> --services calendar브라우저가 열리면 Google 계정으로 로그인하여 권한을 허용해주세요.
인증이 확인되면 GOG_ACCOUNT 환경변수 또는 --account 플래그로 계정을 지정한다.
3. 요청 분류 및 실행
사용자 요청을 아래 중 하나로 분류하여 실행한다. 캘린더 ID는 기본적으로 primary를 사용한다.

What ships with it
1 file 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.
- 8d ago First seen · 227 lines · 97 tokens per session scan A b46da8538a12
google-calendar is a skill published in the GitHub repository greatSumini/cc-system (436 stars, last pushed 2mo ago), licensed MIT. It adds 97 tokens to every session and 1,626 once invoked, about $0.0005 per session on Opus 5. 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.
