### 导出副本边界与技能别名

迁移、安装、修复和经验回写只作用于当前加载的目标宿主技能副本。原 Codex 技能/MCP、下载的源码和 `original-skills` 均为来源材料，不因执行本副本而写入；只有用户另行明确要求配置 Codex 产品本身时，才按该产品流程处理指定目标。脚本需要安装目录或状态目录时，显式提供目标路径；不得从 `CODEX_HOME` 隐式推断写入位置。

跨技能名称可能沿用源库别名。先查 [技能别名表](../../skill-aliases.json)，优先选择同来源、同插件的条目，再使用其 `id` 调用或读取对应入口；不得假定旧 `$skill`、`superpowers:skill` 名称在新宿主直接注册。不能确定目标时先核对，不替换真实产品命令或 Shell 环境变量。

## 跨宿主使用约定

本副本供支持 Agent Skills 的客户端使用。先检查当前宿主实际提供的工具、权限和已连接服务，再执行正文工作流。原文中的宿主工具标识是能力参考；只有实际发现该工具时才可调用，其他宿主应使用经核验的等价 MCP、CLI 或 API。没有等价能力的步骤必须报告不可用，不能虚构调用或完成状态。

技能资源以本技能目录为基准；输出写入当前项目中用户指定的位置。通过技能名称或自然语言触发，具体快捷命令由宿主决定。涉及真实产品、模型 API、协议字段和官方网址的名称保持原意。授权、审批、隐私和工具范围限制在迁移后仍然有效；不得为兼容而扩大权限。具体依赖与迁移说明见同目录 `PORTABILITY.md`。

## Overview

A WhatsApp sender is a phone number registered with WhatsApp Business through Twilio. Registration goes through a lifecycle of statuses before becoming `ONLINE`. Sandbox testing does not require a registered sender — see `twilio-whatsapp-send-message`.

---

## Prerequisites

- Upgraded Twilio account (trial accounts cannot register production senders)
  — See `twilio-account-setup` for signup and upgrade steps
- A phone number capable of receiving SMS or voice verification
- Number must not already be registered with WhatsApp
- 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: Initiate registration
sender = client.messaging.v2.channels.senders.create(
    sender_id="whatsapp:+15017122661",
    verification_method="sms"
)
print(sender.sid)     # XExxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
print(sender.status)  # CREATING

# Step 2: Submit the OTP Twilio sends to the number
sender = client.messaging.v2.channels.senders(sender.sid).update(
    verification_code="123456"
)
print(sender.status)  # ONLINE (may pass through TWILIO_REVIEW first)
```

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

// Step 1: Initiate registration
const sender = await client.messaging.v2.channels.senders.create({
    senderId: "whatsapp:+15017122661",
    verificationMethod: "sms",
});
console.log(sender.sid, sender.status);

// Step 2: Submit the OTP
const verified = await client.messaging.v2.channels.senders(sender.sid).update({
    verificationCode: "123456",
});
console.log(verified.status);
```

## Sender Lifecycle Statuses

| Status | Meaning |
|--------|---------|
| `CREATING` | Registration initiated |
| `PENDING_VERIFICATION` | Awaiting OTP submission |
| `VERIFYING` | OTP being validated |
| `TWILIO_REVIEW` | Under Twilio/Meta review |
| `ONLINE` | Active and ready to send |
| `OFFLINE` | Inactive — check `offlineReasons` |
| `DRAFT` | Incomplete registration |

## Key Patterns

### Set Business Profile

**Python**
```python
sender = client.messaging.v2.channels.senders(SENDER_SID).update(
    profile_name="Acme Support",
    profile_about="Official support channel for Acme Corp",
    profile_address="123 Main St, San Francisco, CA",
    profile_vertical="PROFESSIONAL_SERVICES",
    profile_logo_url="https://acme.com/logo.png",
    profile_websites=["https://acme.com"]
)
```

**Node.js**
```node
const sender = await client.messaging.v2.channels.senders(SENDER_SID).update({
    profileName: "Acme Support",
    profileAbout: "Official support channel for Acme Corp",
    profileAddress: "123 Main St, San Francisco, CA",
    profileVertical: "PROFESSIONAL_SERVICES",
    profileLogoUrl: "https://acme.com/logo.png",
    profileWebsites: ["https://acme.com"],
});
```

### Configure Webhooks

**Python**
```python
sender = client.messaging.v2.channels.senders(SENDER_SID).update(
    callback_url="https://yourapp.com/whatsapp/inbound",
    callback_method="POST",
    status_callback_url="https://yourapp.com/whatsapp/status"
)
```

**Node.js**
```node
await client.messaging.v2.channels.senders(SENDER_SID).update({
    callbackUrl: "https://yourapp.com/whatsapp/inbound",
    callbackMethod: "POST",
    statusCallbackUrl: "https://yourapp.com/whatsapp/status",
});
```

### Retrieve and List Senders

**Python**
```python
sender = client.messaging.v2.channels.senders(SENDER_SID).fetch()
print(sender.status)

for s in client.messaging.v2.channels.senders.list():
    print(s.sid, s.status)
```

**Node.js**
```node
const sender = await client.messaging.v2.channels.senders(SENDER_SID).fetch();
const senders = await client.messaging.v2.channels.senders.list();
senders.forEach(s => console.log(s.sid, s.status));
```

If a sender is `OFFLINE`, check the `offlineReasons` array in the response (e.g. code `63020` means business hasn't accepted Twilio's Meta invitation).

### Migrate an Existing WhatsApp Number

If a number is already registered on WhatsApp (personal or business):
1. Check: `https://wa.me/<PHONE_NUMBER>?text=hi`
2. Delete the existing WhatsApp account on the device, or disable 2FA on the competing platform
3. Proceed with registration above

### ISV / Tech Provider Flow

Register senders under a client's WhatsApp Business Account (WABA):

**Python**
```python
sender = client.messaging.v2.channels.senders.create(
    sender_id="whatsapp:+15017122661",
    waba_id="client-waba-id"
)
```

**Node.js**
```node
const sender = await client.messaging.v2.channels.senders.create({
    senderId: "whatsapp:+15017122661",
    wabaId: "client-waba-id",
});
```

The client must accept Twilio's invitation in their Meta Business Manager.

---

## CANNOT

- **Cannot register a phone number to multiple WABAs** — Each number belongs to one WABA at a time
- **Cannot exceed 2 senders without Meta Business Verification** — Unverified accounts are limited to 2
- **Cannot exceed 20 senders without exception** — Verified Meta Business Manager: max 20 (50 with exception request)
- **Cannot verify phone number only via SMS** — Voice verification is available if SMS cannot be received

---

## Next Steps

- **Send WhatsApp messages with this sender:** `twilio-whatsapp-send-message`
- **Create message templates:** `twilio-content-template-builder`
- **Send WhatsApp OTPs:** `twilio-verify-send-otp`
