Google Calendar + Tasks Access

Quick start

Create a Google Cloud OAuth client (Desktop app) and save the credentials JSON to
```
~/.config/google-calendar/credentials.json
```
.

Install dependencies (venv recommended):

bash

python3 -m venv ~/.config/google-calendar/venv
~/.config/google-calendar/venv/bin/pip install -r <skill_dir>/scripts/requirements.txt

Authenticate and store a token:

Calendar only:
- ```
<skill_dir>/scripts/gcal-auth
```

Tasks only:

<skill_dir>/scripts/gcal-auth --scopes https://www.googleapis.com/auth/tasks

Calendar + Tasks (single token):

<skill_dir>/scripts/gcal-auth --scopes https://www.googleapis.com/auth/calendar https://www.googleapis.com/auth/tasks

Call the API:
- ```
<skill_dir>/scripts/gcal list-calendars
```

Credentials and tokens

Credentials are expected at

~/.config/google-calendar/credentials.json

by default.

Tokens are stored at
```
~/.config/google-calendar/token.json
```
by default.
Use
```
--token
```
or
```
GCAL_TOKEN_PATH
```
to switch accounts or isolate environments.

Date/time rules

Use RFC3339 for timed events (e.g.,
```
2026-01-22T10:00:00-08:00
```
).
Use
```
YYYY-MM-DD
```
for all-day events and set
```
end
```
to the next day (exclusive).
Set
```
--time-zone
```
when the datetime has no offset.

Advanced usage

Use

call

to hit any Calendar API endpoint:

<skill_dir>/scripts/gcal call GET /users/me/calendarList

<skill_dir>/scripts/gcal call POST /calendars/primary/events --body-file /path/to/event.json

Use
```
--body-file
```
or
```
--body
```
(JSON string) for complex payloads (attendees, recurrence, conferenceData).
Run multiple accounts by using different token files with
```

Safety

Confirm intent before creating, updating, or deleting events.
Keep OAuth credentials and token files out of git.
