## What it does

The skill lets an agent work with Calendly through the Membrane CLI. It can inspect organization members, users, scheduled events, invitees, event types, and available time slots. Listed actions also cover event cancellation, one-time scheduling links, and webhook subscriptions for invitee-related events.

The workflow uses a Calendly connection, an intent-based action search, and an action run with JSON parameters. When a listed action does not fit, the skill supports sending a request to the Calendly API through Membrane’s proxy. Network access and a valid Membrane account are required, with the Free tier supported. Without them, the Calendly connection will not work.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add membranedev/application-skills --skill calendly -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/calendly/SKILL.md

## When to use it
- retrieve the authenticated Calendly user
- find open slots for an event type
- list scheduled events and their invitees
- cancel a scheduled Calendly event
- create a webhook subscription for invitee events

## Example prompts
- Connect Calendly and list open time slots for the selected event type during a given date range.
- Show scheduled Calendly events together with their invitees.
- Create a Calendly webhook subscription for `invitee.created` and `invitee.canceled`.

# Calendly

Calendly is a scheduling automation tool that eliminates the back-and-forth of finding meeting times. It allows users to share availability and let others book appointments directly into their calendar. Sales teams and customer success managers commonly use it to schedule demos and meetings.

Official docs: https://developer.calendly.com/

## Calendly Overview

- **Event**
  - **Invitee**
- **User**
- **Scheduling Link**

Use action names and parameters as needed.

## Working with Calendly

This skill uses the Membrane CLI to interact with Calendly. 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 Calendly

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

```bash
membrane connection ensure "https://calendly.com/" --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**.

#### 1b. Wait for the connection to be ready

If the connection is in `BUILDING` state, poll until it's ready:

```bash
npx @membranehq/cli connection get <id> --wait --json
```

The `--wait` flag long-polls (up to `--timeout` seconds, default 30) until the state changes. Keep polling until `state` is no longer `BUILDING`.

The resulting state tells you what to do next:

- **`READY`** — connection is fully set up. Skip to **Step 2**.
- **`CLIENT_ACTION_REQUIRED`** — the user or agent needs to do something. The `clientAction` object describes the required action:
  - `clientAction.type` — the kind of action needed:
