## What it does

This skill plans operational boundaries in Sent v3 before provisioning begins. It defines tenant isolation boundaries. The skill outlines whether contacts and TCR templates are inherited or shared, and structures payloads for `POST /v3/profiles`. Live MCP actions belong in `sent-profile-provisioning`, leaving this skill focused on structural architecture.

Sent v3 separates credential boundaries strictly. An organization API key can act for a child profile via the `x-profile-id` header while drawing from the shared organization rate limit. Conversely, a profile-specific API key isolates credentials and limits: sending `x-profile-id` with it causes a 403 error. The legacy `x-sender-id` header is rejected.

Webhook events omit internal tenant identifiers. Because of that, you must store and map the returned `message_id` and inbound phone numbers to your tenant IDs locally. Inferring ownership from `account_id` alone fails because multiple tenant profiles live under one organization.

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add sentdm/sent-plugin --skill sender-profile-architect -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add sentdm/sent-plugin --skill sender-profile-architect -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add sentdm/sent-plugin --skill sender-profile-architect -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/sender-profile-architect/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

# Sender Profile Architect

A Sender Profile is the operational boundary for tenant identity, channel configuration, inherited resources, billing, and credentials. Use this skill before provisioning when a poor boundary would mix brands, compliance posture, rate-limit impact, or webhook ownership.

For live MCP profile lifecycle operations use `sent-profile-provisioning`; for market requirements use `sent-compliance`. MCP selects an acting profile with optional `profileId` on ordinary account tools for organization grants only. `sender_profiles.*` tools operate on target `id` and reject acting `profileId`. REST headers below are not MCP arguments.

## Recommended tenancy model

When tenants require isolation, recommend one Sent organization with one Sender Profile per tenant. A shared profile is appropriate only when the tenants genuinely share one brand, sender resources, compliance posture, billing/rate-limit expectations, and operational blast radius.

Do not recommend pooled-by-default architecture. Make the isolation decision explicit using [references/multi-tenancy-patterns.md](references/multi-tenancy-patterns.md).

## Authentication patterns

Sent v3 supports both:

| Pattern | Headers | Blast radius |
| --- | --- | --- |
| Profile-specific API key | `x-api-key` | Profile-scoped credentials and rate-limit context. Do not add `x-profile-id`. |
| Organization API key acting for a child | `x-api-key` plus `x-profile-id: <profile UUID>` | Organization credential can reach permitted child profiles; rate limits remain in the organization pool. |

Only organization keys may send `x-profile-id`. A profile key that sends it receives `403`. A profile outside the organization returns `404`. `X-Profile-Id` can be echoed in scoped responses.

`x-sender-id` is legacy v1/v2 terminology only. Do not use it for v3 authentication or routing.

Choose profile keys when tenant-level credential isolation and revocation are primary. Choose organization-key scoping for centrally controlled integrations that can protect a broader credential and deliberately accept a shared organization rate-limit pool.

## Profile creation model

Create with `POST /v3/profiles`. `name` is required. Current optional areas include:

- identity: `icon`, `description`, `short_name`;
```
