Set up and send emails via a user-provided Resend account (BYO email provider).

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

## Overview

Send emails through the user's own Resend account. The user provides their Resend API key and you send via their domain.

## Setup

### Step 0: Check Existing Configuration

Before starting, check whether Resend is already configured:

```bash
bun skills/resend-setup/scripts/check-config.ts
```

The script outputs JSON: `{ "configured": boolean, "hasApiKey": boolean, "hasWebhookSecret": boolean, "details": string }`.

- If `configured` is `true` — Resend is already set up. Offer to verify the connection or reconfigure.
- If `configured` is `false` — continue to Step 1.

### Step 1: Store the API Key

Run the store script to securely collect the API key:

```bash
bun skills/resend-setup/scripts/store-api-key.ts
```

The script opens a secure credential prompt, stores the key with the correct injection templates, and exits. If it exits 0, the key is stored. Exit code **130** means the user cancelled the prompt — nothing was stored; that's a valid choice, not an error, so ask whether they'd like to try again rather than treating it as a failure. Any other non-zero exit is a real failure. **Never ask for the key in chat.**

### Step 2: Detect the Domain

How to install

The exact contents, by fingerprint

mdr add vargasjr-dev/mycadet-temp/resend-setup@sha256:72e66a0ac9752cfe

The line at the top of this page pins the label git:20261007.cbfc397, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
