## What it does

The skill lays out Twilio workflows: sending and receiving SMS, notification templates, two-factor authentication through the Verify API, outbound calls and an IVR menu. Inside are YAML configs and JavaScript examples, from building a message and looking up a number to sending it and handling the delivery status. Templates cover order confirmation, shipping updates, appointment reminders and verification codes.

A separate block handles two-way messaging: a welcome after opt-in, replies to `HELP`, `STATUS` and `TRACK`, opt-out on `STOP` and resubscribe on `START`. Bulk campaigns get audience filters, scheduling, batch size and a delivery report. The voice side includes TwiML scripts with call recording and keypad routing.

The skill talks to the `communication-mcp` MCP server with the `twilio_send_sms`, `twilio_voice_call`, `twilio_lookup` and `twilio_verify` tools. So you need that server running and Twilio credentials: a sender number or messaging service SID, plus a service SID for Verify. None of the flows start without them, so check access before wiring this into a production path.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add claude-office-skills/skills --skill twilio-sms-automation -a claude-code
```
```bash
npx skills add claude-office-skills/skills --skill twilio-sms -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add claude-office-skills/skills --skill twilio-sms -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add claude-office-skills/skills --skill twilio-sms -a cursor
```

2. **Manually: put the files in place**

# Twilio SMS Automation

Comprehensive skill for automating SMS, voice, and verification workflows with Twilio.

## Core Workflows

### 1. SMS Messaging Flow

```
SMS AUTOMATION FLOW:

│    Trigger      │
│  (Event/API)    │
└────────┬────────┘
         ▼

└─────────────────┘
```

### 2. Message Configuration

```yaml
sms_config:
  sender:
    phone_number: "+1234567890"
    messaging_service_sid: "MG..."  # For higher throughput
    
  defaults:
    status_callback: "https://api.example.com/sms/status"
    validity_period: 14400  # 4 hours
    
  rate_limiting:
    messages_per_second: 10
    daily_limit_per_recipient: 5
    
  compliance:
    opt_out_keywords: ["STOP", "UNSUBSCRIBE", "CANCEL"]
    opt_in_required: true
    quiet_hours:
      start: "21:00"
      end: "09:00"
      timezone: "America/New_York"
```

## Message Templates

### Notification Templates

```yaml
