# google-calendar

This skill gives your agent access to Google Calendar: it books events, checks free slots, reads and edits calendars. Handy when scheduling happens from the terminal.

## What it does

Everything runs through the Membrane CLI, which handles Google sign-in and token refresh for you. Install it with `npm install -g @membranehq/cli@latest`, then run `membrane login --tenant --clientName=<agentType>`. On a headless machine the command prints an authorization URL; once the user finishes in the browser, close the loop with `membrane login complete <code>`.

A connection is created with `membrane connection ensure "https://calendar.google.com/calendar" --json`. While the state reads `BUILDING`, poll it with `npx @membranehq/cli connection get <id> --wait --json` until it turns `READY`. Actions are then found by intent: `membrane action list --connectionId=CONNECTION_ID --intent "QUERY" --limit 10 --json`, and executed with `membrane action run <actionId> --connectionId=CONNECTION_ID --json`.

Ready-made actions cover `query-free-busy`, `create-event`, `quick-add-event`, `update-event`, `list-events` and calendar management. When nothing fits, requests go straight to the Google Calendar API through the proxy: `membrane request CONNECTION_ID /path/to/endpoint`. A Membrane account and network access are required, so an air-gapped setup with no outbound traffic will not work.

## Requirements
- Works with: Google Workspace

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add membranedev/application-skills --skill google-calendar -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/google-calendar/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/google-calendar/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add membranedev/application-skills --skill google-calendar -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/google-calendar/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add membranedev/application-skills --skill google-calendar -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/google-calendar/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install membranedev/application-skills google-calendar
```

2. **Manually: put the files in place**
- File: `.github/skills/google-calendar/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add membranedev/application-skills --skill google-calendar -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/membranedev/application-skills --path skills/google-calendar
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/google-calendar/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add membranedev/application-skills --skill google-calendar -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/membranedev/application-skills/tree/HEAD/skills/google-calendar/SKILL.md

## When to use it
- book an event from a plain text line
- find open slots for a meeting
- reschedule or cancel a meeting
- pull events for a date range
- set up a separate calendar for a project

## Example prompts
- Create an event called “Team sync” tomorrow at 3pm on my calendar
- Show me when I'm free on Thursday afternoon
- Move the `client-call` meeting one hour later

# Google Calendar

Google Calendar is a time-management and scheduling application. It allows users to create and track events, set reminders, and share calendars with others. It's widely used by individuals, teams, and organizations to organize their schedules and coordinate activities.

Official docs: https://developers.google.com/calendar

## Google Calendar Overview

- **Calendar**
  - **Event**
- **Settings**

## Working with Google Calendar

This skill uses the Membrane CLI to interact with Google Calendar. Membrane handles authentication and credentials refresh automatically — so you can focus on the integration logic rather than auth plumbing.

### Install the CLI

Install the Membrane CLI so you can run `membrane` from the terminal:

```bash
npm install -g @membranehq/cli@latest
```

### Authentication

```bash
membrane login --tenant --clientName=<agentType>
```

This will either open a browser for authentication or print an authorization URL to the console, depending on whether interactive mode is available.

**Headless environments:** The command will print an authorization URL. Ask the user to open it in a browser. When they see a code after completing login, finish with:

```bash
membrane login complete <code>
```

Add `--json` to any command for machine-readable JSON output.

**Agent Types** : claude, openclaw, codex, warp, windsurf, etc. Those will be used to adjust tooling to be used best with your harness

### Connecting to Google Calendar

Use `membrane connection ensure` to find or create a connection by app URL or domain:

```bash
membrane connection ensure "https://calendar.google.com/calendar" --json
```
The user completes authentication in the browser. The output contains the new connection id.

This is the fastest way to get a connection. The URL is normalized to a domain and matched against known apps. If no app is found, one is created and a connector is built automatically.

If the returned connection has `state: "READY"`, skip to **Step 2**.
