## What it does

This skill walks you through US A2P SMS registration on 10-digit long codes in Sent. It keeps two things apart on purpose: the compliance evidence packet and the exact API request. They use different schemas and different validators.

Two scripts do the checking. `python scripts/validate_10dlc_packet.py evidence.json` validates the evidence packet, which uses snake_case fields and the internal version `sent-10dlc-evidence/v1`. `python scripts/validate_campaign_payload.py campaign.json` validates the campaign request, written in camelCase with a `campaign` wrapper. Reference files cover use-case classification and rejection remediation.

There is no standalone brand path in the current v3 API. You create the brand inside `POST /v3/profiles` with the `brand` field and `inherit_tcr_brand: false`. Inherited campaigns are read-only, and a profile cannot supply `brand` while brand inheritance is on. Before preparing evidence here, the skill points you to `sent-compliance` for current field requirements and the exact SMS setup call. Never put real consumer data in fixtures or samples.

## When to use it
- build a consent evidence packet for 10DLC registration
- validate a campaign request before sending it to Sent
- decide between brand inheritance and a dedicated campaign
- work out why TCR rejected a campaign and fix it
- pick the right use case and sample messages for your traffic

## Example prompts
- Help me prepare the 10DLC registration for our brand in Sent
- Validate my evidence packet: `python scripts/validate_10dlc_packet.py evidence.json`
- Build the campaign request for ACCOUNT_NOTIFICATION and run it in sandbox

# SMS 10DLC Registration

Use this skill for US A2P SMS over 10-digit long codes. Separate the compliance evidence packet from the exact Sent API request; they have different schemas and validators.

For current field and document requirements or an exact SMS setup call, use `sent-compliance` before preparing the registration evidence here. Its plan creates a new Sender Profile and does not manage campaigns on an existing profile.

## Current Sent resource model

There is no standalone brand CRUD path in the current v3 API.

- Create a dedicated brand inside `POST /v3/profiles` using `brand` and `inherit_tcr_brand: false`.
- List/create campaigns with `GET|POST /v3/profiles/{profileId}/campaigns`.
- Update/delete with `PUT|DELETE /v3/profiles/{profileId}/campaigns/{campaignId}`.

Reject guidance that reintroduces a free-standing brand path.

## Choose inheritance deliberately

| Brand | Campaign | Settings |
| --- | --- | --- |
| Inherit both | Organization brand and campaign | `inherit_tcr_brand: true`, `inherit_tcr_campaign: true` |
| Inherit brand, own campaign | Shared legal brand with tenant-specific traffic | brand true, campaign false |
| Own both | Dedicated tenant/business | both false and supply `brand` during profile creation |

Inherited campaigns are read-only. A profile cannot supply `brand` while brand inheritance is true.

## Two validation layers

### Evidence readiness packet

The private packet uses the explicit internal version `sent-10dlc-evidence/v1` and snake_case evidence fields. It is not an API payload.

```bash
python scripts/validate_10dlc_packet.py evidence.json
```

Collect legal identity, public website/policy links, consent proof, message flow, opt-in/opt-out/help responses and keywords, use cases, and realistic samples. See [references/10dlc-evidence-checklist.md](references/10dlc-evidence-checklist.md).

### Sent campaign request

The API request uses exact camelCase and a `campaign` wrapper:

<!-- sent-campaign-request -->
```json
{
  "campaign": {
    "name": "Acme account notifications",
    "description": "Account and delivery notifications for opted-in customers.",
    "type": "App",
    "useCases": [
      {
````

The third-party file has ended. Everything between the 0a573b91a993c715 tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
