# Add DeltaChat Channel The adapter drives the `@deltachat/stdio-rpc-server` JSON-RPC subprocess directly — pure Node.js against the DeltaChat core library. Messages are delivered over email with Autocrypt/OpenPGP encryption. ## Install ### 1. Copy the adapter and its registration test Fetch the `channels` branch from the configured remote that carries it, then overwrite the skill-owned files with the canonical registry copies: ```nc:copy from-branch:channels src/channels/deltachat.ts src/channels/deltachat-registration.test.ts ``` ### 2. Append the self-registration import Append to `src/channels/index.ts` (skip if already present): ```nc:append to:src/channels/index.ts import './deltachat.js'; ``` ### 3. Install the adapter package (pinned) ```nc:dep @deltachat/stdio-rpc-server@2.49.0 ``` ### 4. Build and validate ```nc:run effect:build pnpm run build ``` ```nc:run effect:test pnpm exec vitest run src/channels/deltachat-registration.test.ts ``` Both must be clean before proceeding. `deltachat-registration.test.ts` is the one integration test: it imports the real channel barrel and asserts the registry contains `deltachat`. It goes red if the `import './deltachat.js';` line is deleted or drifts, if the barrel fails to evaluate (so the channel genuinely would not register), or if `@deltachat/stdio-rpc-server` isn't installed (the import throws) — so it also implicitly verifies the dependency from step 4. Importing is safe: deltachat instantiates the rpc client on...
