## What it does

This skill creates a Twilio Messaging Service, adds an SMS-capable phone number, and sends messages through `messaging_service_sid` instead of a fixed `from` number. Twilio can select a sender from the service pool. The setup covers sticky sender behavior, area-code matching, message validity, smart encoding, and MMS-to-SMS conversion.

It also covers scheduled delivery, branded link shortening with click tracking, the compliance toolkit, SMS pumping protection, and alerts. Examples use the Python or Node.js Twilio SDK, with service settings passed through the Twilio API. A Twilio account, an SMS-capable number, `TWILIO_ACCOUNT_SID`, and `TWILIO_AUTH_TOKEN` are required before setup can run.

Install the skill for Codex; the listed platforms are Codex and ChatGPT. Scheduled delivery needs `messagingServiceSid`, so a request that only supplies `from` does not use that flow.

## Install

### Codex (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill twilio-messaging-services -a codex
```

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

### Claude Code

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill twilio-messaging-services -a claude-code
```

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

### Cursor

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install openai/plugins twilio-messaging-services
```

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

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/openai/plugins --path plugins/twilio-developer-kit/skills/twilio-messaging-services
```

### Windsurf (Devin Desktop)

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

### Claude.ai

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

## When to use it
- create a Messaging Service for production sends
- add phone numbers to a sender pool
- match senders to recipients by area code
- schedule messages through the Twilio API
- configure SMS pumping protection

## Example prompts
- Create a Twilio Messaging Service and add the number `PNxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx` to its sender pool.
- Show Python code that sends notifications through `messagingServiceSid` and keeps the same sender for each recipient.
- Schedule a message, then cancel it using `SMxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx` if the delivery should not proceed.

  Create and configure Twilio Messaging Services for production messaging.
  Covers sender pools, geo-match, sticky sender, message scheduling,
  compliance toolkit, SMS pumping protection, link shortening, and
  intelligent alerts. Use this skill when setting up production-ready
  messaging infrastructure.
---

## Overview

A Messaging Service groups senders (phone numbers, short codes, toll-free numbers) with shared configuration. Send via `messagingServiceSid` instead of a specific `from` number — Twilio picks the best sender automatically.

**Use a Messaging Service for all production sends.** Beyond sender pools, it unlocks compliance toolkit, SMS pumping protection, link shortening, message scheduling, and intelligent alerts. For channel selection guidance, see `twilio-messaging-overview`.

---

## Prerequisites

- Twilio account with at least one SMS-capable phone number
  — New to Twilio? See `twilio-account-setup`
- Environment variables:
  - `TWILIO_ACCOUNT_SID`
  - `TWILIO_AUTH_TOKEN`
  — See `twilio-iam-auth-setup` for credential setup and best practices
- SDK: `pip install twilio` / `npm install twilio`

---

## Quickstart

**Python**
```python
import os
from twilio.rest import Client

client = Client(os.environ["TWILIO_ACCOUNT_SID"], os.environ["TWILIO_AUTH_TOKEN"])

# Step 1: Create the service
service = client.messaging.v1.services.create(
    friendly_name="Production Notifications Service"
)
print(service.sid)  # MGxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx — save as MESSAGING_SERVICE_SID

# Step 2: Add a phone number
client.messaging.v1 \
    .services(service.sid) \
    .phone_numbers \
    .create(phone_number_sid="PNxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")

# Step 3: Send via the service
message = client.messages.create(
    messaging_service_sid=service.sid,
    to="+15558675310",
    body="Your order has shipped."
)
print(message.sid)
```

**Node.js**
```node
const twilio = require("twilio");
const client = twilio(process.env.TWILIO_ACCOUNT_SID, process.env.TWILIO_AUTH_TOKEN);

// Step 1: Create the service
const service = await client.messaging.v1.services.create({
    friendlyName: "Production Notifications Service",
});
console.log(service.sid);

// Step 2: Add a phone number
await client.messaging.v1
    .services(service.sid)
    .phoneNumbers.create({ phoneNumberSid: "PNxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" });

// Step 3: Send via the service
const message = await client.messages.create({
    messagingServiceSid: service.sid,
    to: "+15558675310",
    body: "Your order has shipped.",
});
console.log(message.sid);
```

## Key Patterns

### Create Service with Webhooks and Features

**Python**
```python
service = client.messaging.v1.services.create(
    friendly_name="Marketing Campaigns",
    inbound_request_url="https://yourapp.com/sms/inbound",
    status_callback="https://yourapp.com/sms/status",
    sticky_sender=True,
````
