# Add Resend Email Channel

Connect NanoClaw to email via Resend for async email conversations. NanoClaw
doesn't ship channels in trunk, this skill copies the Resend adapter in from the
`channels` branch.

The mechanical steps under **Apply** carry `nc:` directive fences: an agent reads
the prose and applies them, and a parser can apply them deterministically from
the same document. Every directive is idempotent, so the whole skill is safe to
re-run; anything a parser can't apply falls back to the prose beside it.

## Apply

### 1. Copy the adapter

Fetch the `channels` branch and copy the Resend adapter into `src/channels/`
(overwrite, the branch is canonical):

```nc:copy from-branch:channels
src/channels/resend.ts
src/channels/resend-registration.test.ts
```

### 2. Register the adapter

Append the self-registration import to the channel barrel (skipped if the line
is already present). This one line is the skill's only reach-in into core:

```nc:append to:src/channels/index.ts
import './resend.js';
```

### 3. Install the adapter package

Pinned to an exact version, the supply-chain policy rejects ranges and `latest`:

```nc:dep
@resend/chat-sdk-adapter@0.3.0
```

### 4. Build and validate

Build guards the typed `createChatSdkBridge(...)` core call and proves the
dependency is installed (the adapter imports `@resend/chat-sdk-adapter`; if it
isn't installed the barrel throws). End-to-end email delivery against a real
domain is verified manually once the service runs.

```nc:run effect:build
pnpm run build
```
```nc:run effect:test
pnpm exec vitest run src/channels/resend-registration.test.ts
```

`resend-registration.test.ts` imports the real channel barrel and asserts the
registry contains `resend`. It goes red if the import line is deleted or drifts,
if the barrel fails to evaluate, or if `@resend/chat-sdk-adapter` isn't installed
(the import throws), so it also covers the dependency from step 3.
