What it does

Google Calendar is an agent skill from greatSumini/cc-system. gogcli를 사용하여 Google Calendar 일정을 조회, 검색, 생성, 수정, 삭제하는 skill. "일정 확인해줘", "캘린더 보여줘", "오늘 일정", "이번주 일정", "미팅 잡아줘", "일정 추가", "calendar events", "일정 생성", "스케줄 확인", "빈 시간 확인", "일정 삭제" 등 Google Calendar 관련 요청에 트리거된다.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/gog-calendar-commands.md`).

It sits in Productivity & Automation. It works with Google Calendar. The licence is MIT.

When your agent uses it

  • Productivity & Automation work in your project

Example prompts

  • “calendar events”
  • “/google-calendar”

Workflow steps

What it can do on your machine

Read from SKILL.md and the folder at commit 172bdd4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • console.cloud.google.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Google Calendar loads about 1.1k tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 56 tokens; SKILL.md has 357 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~56
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
gogcli를 사용하여 Google Calendar 일정을 조회, 검색, 생성, 수정, 삭제하는 skill. "일정 확인해줘", "캘린더 보여줘", "오늘 일정", "이번주 일정", "미팅 잡아줘", "일정 추가", "calendar events", "일정 생성", "스케줄 확인", "빈 시간 확인", "일정 삭제" 등 Google Calendar 관련 요청에 트리거된다.

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
bash
which gog

명령이 실패하면 사용자에게 설치를 안내한다:

gogcli 설치 안내

bash
brew install gogcli

설치 완료 후 다시 시도해주세요.

설치가 확인되면 다음 단계로 진행한다.

2. 인증 확인
bash
gog auth list

계정이 없으면 OAuth 설정을 안내한다:

Google Calendar 인증 설정 가이드

  1. Google Cloud Console에서 프로젝트 생성
  2. Google Calendar API 활성화
  3. OAuth 동의 화면 설정 → 테스트 사용자 추가
  4. OAuth 클라이언트 생성 → "Desktop app" → JSON 다운로드
  5. 터미널에서 아래 명령 실행:
bash
gog auth credentials ~/Downloads/client_secret_....json
gog auth add <your-email@gmail.com> --services calendar

브라우저가 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.

캘린더 목록 조회
bash
gog calendar calendars --json
오늘 일정
bash
gog calendar events primary --today --json
이번주 일정
bash
gog calendar events primary --week --json
N일간 일정
bash
gog calendar events primary --days <N> --json
특정 기간 일정
bash
gog calendar events primary --from <시작일> --to <종료일> --json
  • 상대 날짜 지원: --from today --to friday
  • ISO 8601: --from 2026-04-01T00:00:00Z --to 2026-04-08T00:00:00Z
모든 캘린더의 일정
bash
gog calendar events --all --today --json
일정 검색
bash
gog calendar search "<키워드>" --today --json
gog calendar search "<키워드>" --days <N> --json

검색 기본 범위: 30일 전 ~ 90일 후 (--from/--to로 조정 가능)

일정 생성
bash
gog calendar create primary \
  --summary "<일정 제목>" \
  --from <시작시간> \
  --to <종료시간> \
  [--attendees "alice@example.com,bob@example.com"] \
  [--location "<장소>"] \
  [--send-updates all]

종일 일정:

bash
gog calendar create primary \
  --summary "<일정 제목>" \
  --from 2026-04-15 \
  --to 2026-04-16 \
  --all-day

반복 일정:

bash
gog calendar create primary \
  --summary "<일정 제목>" \
  --from <시작시간> \
  --to <종료시간> \
  --rrule "RRULE:FREQ=WEEKLY;COUNT=4"
일정 수정
bash
gog calendar update primary <eventId> \
  --summary "<수정된 제목>" \
  --from <새 시작시간> \
  --to <새 종료시간>

참석자 추가 (기존 유지):

bash
gog calendar update primary <eventId> \
  --add-attendee "newperson@example.com"
일정 삭제
bash
gog calendar delete primary <eventId> --force

참석자에게 알림 전송:

bash
gog calendar delete primary <eventId> --send-updates all --force
초대 응답
bash
gog calendar respond primary <eventId> --status accepted
gog calendar respond primary <eventId> --status declined
gog calendar respond primary <eventId> --status tentative
빈 시간 확인 (Free/Busy)
bash
gog calendar freebusy --calendars "primary" \
  --from <시작시간> \
  --to <종료시간> \
  --json
일정 충돌 확인
bash
gog calendar conflicts --all --today --json

4. 쓰기 작업 확인

일정 생성, 수정, 삭제 전에 반드시 사용자에게 아래 내용을 확인받는다:

  • 생성: 제목, 시간, 참석자, 장소
  • 수정: 변경 항목과 변경 내용
  • 삭제: 삭제 대상 일정 제목과 시간
5. 결과 출력

JSON 결과를 파싱하여 사용자에게 읽기 좋게 정리한다:

  • 일정 목록: 날짜, 시간, 제목, 장소를 테이블 형태로
  • 일정 상세: 제목, 시간, 참석자, 장소, 설명 등
  • 생성/수정 결과: 성공 여부와 이벤트 ID

Invariants

  • 조회 명령에는 항상 --json 플래그를 붙여 파싱 가능한 출력을 얻는다
  • 일정 생성/수정/삭제는 실행 전 반드시 사용자에게 내용을 확인받는다
  • 캘린더 ID를 지정하지 않으면 primary를 기본값으로 사용한다
  • gogcli 미설치 또는 미인증 상태에서는 명령을 실행하지 않고 설정 안내를 진행한다
  • OAuth 자격증명은 gogcli 자체 keyring에 저장된다 — skill 디렉토리에 저장하지 않는다
  • GOG_ACCOUNT 환경변수가 설정되어 있으면 우선 사용한다
  • 시간은 사용자의 로컬 타임존 기준으로 표시한다

주의사항

  • --send-updates all을 명시하지 않으면 참석자에게 알림이 가지 않는다.
  • 반복 일정 수정 시 단일 인스턴스만 변경할지, 전체를 변경할지 확인한다.
  • GOG_TIMEZONE 환경변수로 기본 출력 타임존을 설정할 수 있다 (예: Asia/Seoul).
