## What it does

The skill equips coding agents with syntax for managing Twilio infrastructure via terminal commands. It details profile creation, regional edge routing, purchasing phone numbers, sending SMS, and transmitting emails with SendGrid attachments. It also covers official plugins like `@twilio-labs/plugin-serverless` for function deployments and `@twilio-labs/plugin-watch` for live event streams.

Local webhook debugging requires extra tooling because the CLI rejects `localhost` endpoints outright. A tunneling service like ngrok must be installed independently to receive webhook callbacks on a local port.

Commands fetching message or call records cap output at 50 entries unless overridden by `--limit`. The API timeout is fixed at 30 seconds, so prolonged background tasks might fail silently.

## Install

### Codex (native platform)

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

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

### Claude Code

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

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

### Cursor

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install openai/plugins twilio-cli-reference
```

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

### Gemini CLI

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

### Windsurf (Devin Desktop)

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

### 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/openai/plugins/tree/HEAD/plugins/twilio-developer-kit/skills/twilio-cli-reference/SKILL.md

## When to use it
- Provision phone numbers and set SMS or voice webhook URLs
- Send SMS messages and SendGrid emails directly from terminal
- Deploy Twilio Functions and Assets with the serverless plugin
- Monitor live debugger alerts and calls using `@twilio-labs/plugin-watch`

## Example prompts
- Search for available local numbers with area code 415 and purchase one
- Send an SMS to +14155556789 using Twilio CLI
- Initialize a blank Twilio serverless project and start it locally

  Twilio CLI reference for managing Twilio resources from the terminal.
  Covers installation, credential profiles, phone number provisioning,
  sending SMS and email, webhook configuration, local development with
  a tunneling service, debugging with watch and logs, serverless deployment, and
  plugin ecosystem. Use when the developer asks to "just do it",
  "set this up", "run a command", mentions "CLI", "command line", or
  "terminal", or when an AI agent can execute a task directly instead
  of writing application code.

## Overview

The Twilio CLI lets you manage Twilio resources, send messages, configure webhooks, and deploy serverless functions directly from the terminal. AI coding agents can use CLI commands to provision resources and test integrations without writing application code.

**Install:**

| Platform | Command |
|----------|---------|
| macOS | `brew tap twilio/brew && brew install twilio` |
| Windows | `scoop bucket add twilio-scoop https://github.com/twilio/scoop-twilio-cli && scoop install twilio-cli` |
| Linux (apt) | See `twilio-cli/getting-started/install` for repo setup, then `apt install twilio` |
| npm | `npm install -g twilio-cli` |

**Update:** `brew upgrade twilio` / `scoop update twilio-cli` / `npm install -g twilio-cli@latest`

## Authentication & Profiles

```bash
# First-time login — creates a local API key stored as a profile
twilio login

# Named profiles for multiple accounts
twilio profiles:create --account-sid ACxxx --auth-token xxx --profile staging
# Avoid --auth-token as a plain argument — it will be stored in shell history. Use TWILIO_AUTH_TOKEN env var instead.
twilio profiles:list
twilio profiles:use staging

# Run a single command against a different profile
twilio api:core:messages:list -p production

# Subaccount access
twilio api:core:messages:list --account-sid ACxxx_SUBACCOUNT
```

**Credential priority:** explicit `-p`/`--account-sid` flag > env vars (`TWILIO_ACCOUNT_SID`, `TWILIO_AUTH_TOKEN`) > active profile.

---

## Phone Numbers

```bash
# Search available numbers (US local, area code 415)
twilio api:core:available-phone-numbers:local:list --country-code US --area-code 415

# Purchase a number
twilio api:core:incoming-phone-numbers:create --phone-number "+14155551234"

# List owned numbers
twilio phone-numbers:list

# Set webhooks on a number
twilio phone-numbers:update +14155551234 \
  --sms-url "https://example.com/sms" \
  --voice-url "https://example.com/voice"
```

---

## Send SMS

```bash
twilio api:core:messages:create \
  --from "+14155551234" \
  --to "+14155556789" \
  --body "Your order has shipped."

# List recent messages
twilio api:core:messages:list --to "+14155556789" --limit 10
```

---

## Send Email (SendGrid)

Requires `SENDGRID_API_KEY` environment variable.

```bash
# Configure defaults
twilio email:set --from "noreply@example.com" --subject "Default Subject"

# Send email
twilio email:send \
  --to "user@example.com" \
  --subject "Invoice attached" \
  --text "Please find your invoice." \
  --attachment ./invoice.pdf

# Pipe output as email body
ps aux | twilio email:send --to "ops@example.com" --subject "Process list"
```
