## What it does

The skill generates JSON payloads for the Sent v3 `POST /v3/templates` endpoint. It does not use the Meta Cloud API `components[]` array. The request puts message data inside a `definition` object with a channel-neutral `multiChannel` body limited to 1,024 characters.

Placeholders require explicit typing and sample values, such as `{{0:variable}}`. Naked placeholders like `{{1}}` are rejected. Sent allows up to 10 buttons total, capped at 2 URLs, 1 phone number, 1 voice call, and 1 copy-code action. Authentication templates use `definition.authenticationConfig` with code expirations between 1 and 90 minutes.

Before review submission, the skill checks payloads with `python scripts/lint_waba_template.py template.json`. Relying on Meta Cloud API examples will break the build because Sent enforces its own contract. Using `sandbox: true` allows safe validation without touching live provider state.

```bash
npx skills add sentdm/sent-plugin --skill waba-template-author -a claude-code
```

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

### Codex

## When to use it
- build valid POST /v3/templates request payloads for Sent
- enforce character limits and button constraints for WhatsApp
- classify messaging copy into UTILITY or MARKETING categories
- configure one-time passcode expiration with authenticationConfig
- validate template JSON against the local linter script

## Example prompts
- Create a utility WhatsApp template payload for order shipping updates in Sent v3
- Validate template.json using scripts/lint_waba_template.py and fix placeholder errors
- Generate an authentication template with a copy-code button and a 10-minute code expiration

# WhatsApp Template Author

Use this skill to turn a messaging intent into a valid body for `POST /v3/templates`, review it for WhatsApp policy risk, and explain the resulting lifecycle. Sent's template request is not Meta's Cloud API `components[]` shape.

## Source precedence

When official sources disagree:

1. Use the live Sent v3 OpenAPI for paths, request fields, and response shapes.
2. Use the most specific current Sent guide for lifecycle and policy semantics.
3. Preserve unknown provider values instead of forcing them into a closed enum.

The canonical references are the Sent template-definition guide, the v3 OpenAPI, and the webhook events reference. Do not use snapshot-era v2 examples.

## Authoring workflow

### 1. Establish intent and category

Collect the business event, recipient expectation, requested action, language, channel overrides, and realistic sample values. Choose:

- `UTILITY` for a specific non-promotional transaction, account, or service event.
- `MARKETING` for promotions, offers, re-engagement, product discovery, or mixed promotional content.
- `AUTHENTICATION` for one-time verification codes and supported authentication flows.

If content mixes utility and promotion, classify it as marketing or split it. See [references/waba-template-categories.md](references/waba-template-categories.md).

### 2. Build the Sent create request

`POST /v3/templates` accepts these top-level fields:

| Field | Requirement |
| --- | --- |
| `definition` | Required. Contains `header`, `body`, `footer`, `buttons`, optional `definitionVersion`, and optional `authenticationConfig`. |
| `category` | Optional: `UTILITY`, `MARKETING`, or `AUTHENTICATION`; omit for detection only when ambiguity is acceptable. |
| `language` | Optional locale such as `en_US`. |
| `creation_source` | Optional source string; `from-api` is the documented default. |
| `submit_for_review` | Optional Boolean; default `false`. Draft and validate before review. |
| `sandbox` | Optional Boolean for validation without side effects. |

Do not put `name`, `channels`, `body`, `header`, `buttons`, or `components` at the request root. `name` exists on update/response surfaces, not on the current create request.

```json
{
  "category": "UTILITY",
  "language": "en_US",
  "definition": {
    "header": null,
    "body": {
