Add Resend Email Channel

Connect NanoClaw to email via Resend for async email conversations.

Install

NanoClaw doesn't ship channels in trunk. This skill copies the Resend adapter in from the channels branch.

Pre-flight (idempotent)

Skip to Credentials if all of these are already in place:

• src/channels/resend.ts exists
• src/channels/resend-registration.test.ts exists
• src/channels/index.ts contains import './resend.js';
• @resend/chat-sdk-adapter is listed in package.json dependencies

Otherwise continue. Every step below is safe to re-run.

1. Fetch the channels branch

git fetch origin channels

2. Copy the adapter and its registration test

git show origin/channels:src/channels/resend.ts                 > src/channels/resend.ts
git show origin/channels:src/channels/resend-registration.test.ts > src/channels/resend-registration.test.ts

3. Append the self-registration import

Append to src/channels/index.ts (skip if the line is already present):

import './resend.js';

4. Install the adapter package (pinned)

pnpm install @resend/[email protected]

5. Build and validate

pnpm run build
pnpm exec vitest run src/channels/resend-registration.test.ts

Both must be clean before proceeding. resend-registration.test.ts is the one integration test: it imports the real channel barrel and asserts the registry contains resend. It goes red if the import './resend.js'; 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 implicitly verifies the dependency from step 4. The adapter also calls core's createChatSdkBridge(...); that typed core-API consumption is guarded by pnpm run build.

Credentials

1. Go to resend.com and create an account.
2. Add and verify your sending domain.
3. Go to API Keys and create a new key.
4. Set up a webhook:

• Go to Webhooks > Add webhook.
• URL: https://your-domain/webhook/resend.
• Events: select email.received.
• Copy the signing secret.

Configure environment

Add to .env:

RESEND_API_KEY=re_...
[email protected]
RESEND_FROM_NAME=NanoClaw
RESEND_WEBHOOK_SECRET=your-webhook-secret

Sync to container: mkdir -p data/env && cp .env data/env/env

Next Steps

If you're in the middle of /setup, return to the setup flow now.

Otherwise, run /manage-channels to wire this channel to an agent group.

Channel Info

• type: resend
• terminology: Resend handles email. Each email thread (identified by subject/In-Reply-To headers) is a separate conversation. The "from address" is the bot's identity.
• how-to-find-id: The platform ID is the from email address (e.g. [email protected]). Each sender's email thread becomes its own conversation.
• supports-threads: yes (via email threading headers -- replies to the same thread stay together)
• typical-use: Async communication -- email conversations with longer response expectations
• default-isolation: Same agent group if you want your agent to handle email alongside other channels. Separate agent group if email contains sensitive correspondence that shouldn't be accessible from other channels.
