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 | $0.00051 | $0.01801 |
| Opus 5 | $0.00026 | $0.00901 |
| Sonnet 5 | $0.00010 | $0.00360 |
| Haiku 4.5 | $0.00005 | $0.00180 |
Grade B, and why
google-calendar scanned grade B with 1 finding 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 12d 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.

Google Calendar Sync
Overview
여러 Google 계정(회사, 개인 등)의 캘린더를 한 번에 조회하여 통합된 일정을 제공한다.
- 사전 인증된 refresh token 사용 (매번 로그인 불필요)
- Subagent 병렬 실행으로 빠른 조회
- 계정 간 일정 충돌 감지
트리거 조건
조회
- "오늘 일정", "이번 주 일정 알려줘"
- "캘린더 확인", "스케줄 뭐야"
- "다음 미팅", "내일 뭐 있어"
- "일정 충돌 확인해줘"
생성
- "새 일정 만들어줘", "미팅 추가해줘"
- "내일 3시에 회의 잡아줘"
- "다음 주 월요일 팀 미팅 생성"
수정
- "일정 시간 변경해줘", "미팅 시간 바꿔줘"
- "sync 미팅 14시 21분으로 변경"
- "회의 제목 수정해줘"
삭제
- "일정 삭제해줘", "미팅 취소해줘"
- "이벤트 지워줘"
사전 요구사항
1. Google Cloud 프로젝트 설정
- Google Cloud Console에서 프로젝트 생성
- Calendar API 활성화
- OAuth 2.0 Client ID 생성 (Desktop 유형)
credentials.json다운로드 →references/credentials.json에 저장
2. 계정별 인증 (최초 1회)
# 회사 계정
uv run python .claude/skills/google-calendar/scripts/setup_auth.py --account work
# 개인 계정
uv run python .claude/skills/google-calendar/scripts/setup_auth.py --account personal
브라우저에서 Google 로그인 → refresh token이 accounts/{name}.json에 저장됨
워크플로우
1. 등록된 계정 확인
ls .claude/skills/google-calendar/accounts/
# → work.json, personal.json
2. Subagent 병렬 실행
각 계정별로 Task 도구를 병렬로 호출:
# 병렬 실행 - 단일 메시지에 여러 Task 호출
Task(subagent_type="general-purpose", prompt="fetch calendar for work account")
Task(subagent_type="general-purpose", prompt="fetch calendar for personal account")
각 subagent는 다음을 실행:
uv run python .claude/skills/google-calendar/scripts/fetch_events.py \
--account {account_name} \
--days 7
3. 결과 통합
- 모든 계정의 이벤트를 시간순 정렬
- 동일 시간대 이벤트 = 충돌로 표시
- 계정별 색상/아이콘 구분
출력 형식
📅 2026-01-06 (월) 일정
[09:00-10:00] 🔵 팀 스탠드업 (work)

사용자: "이번 주 일정 알려줘"
1. accounts/ 폴더 확인
└── 등록된 계정: work, personal
2. Subagent 병렬 실행

└── Task: personal 계정 이벤트 조회
3. 결과 수집 (각 subagent 완료 대기)
├── work: 8개 이벤트
└── personal: 3개 이벤트
4. 통합 및 정렬
└── 11개 이벤트, 2건 충돌 감지
5. 출력

What ships with it
7 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.
