Add DeltaChat Channel

Installs and wires a native DeltaChat (email-based, end-to-end encrypted) messaging channel into a NanoClaw deployment.

What it does

Adds a native channel adapter that drives the @deltachat/stdio-rpc-server JSON-RPC subprocess directly — no Chat SDK bridge. Messages travel over ordinary email with Autocrypt/OpenPGP encryption.

The skill walks through:

  • An idempotent pre-flight check, then pulling the adapter and its registration test from the channels branch
  • Appending the self-registration import to src/channels/index.ts and installing the pinned package
  • Building and running the vitest registration test that proves the channel is in the registry
  • .env credentials: email, app password, IMAP/SMTP hosts, ports and security modes (SSL/TLS, STARTTLS, plain)
  • DM bootstrap via the stable invite link and QR SVG (DeltaChat requires a SecureJoin handshake), plus group wiring with /manage-channels or ncl wirings create
  • A log-grep troubleshooting section covering missing credentials, wrong ports, stale lock files, and unresponsive agents

Who it's for

  • Operators self-hosting NanoClaw who want another messaging channel
  • Teams that prefer a decentralised, E2E-encrypted email transport over centralised chat platforms
  • Intermediate-to-advanced users comfortable with systemd/launchd, pnpm and SQLite queries

Examples

  1. "Add the DeltaChat channel" — the skill copies the adapter, installs the pinned dependency, builds and runs the registration test.
  2. Service is up but no chats exist — grep the log for the invite link, open dc-account/invite-qr.svg, and scan it from the DeltaChat app.
  3. Your provider only offers implicit TLS SMTP — set DC_SMTP_SECURITY=1 and DC_SMTP_PORT=465, then restart the unit.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the .claude/skills/add-deltachat folder from the GitHub repo nanocoai/nanoclaw into my ~/.claude/skills/add-deltachat/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/nanocoai/nanoclaw.git && mkdir -p ~/.claude/skills && cp -r nanoclaw/.claude/skills/add-deltachat ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and create the skills folder: mkdir -p ~/.claude/skills
  2. Clone the repository: git clone https://github.com/nanocoai/nanoclaw.git
  3. Copy the skill into place: cp -r nanoclaw/.claude/skills/add-deltachat ~/.claude/skills/
  4. Restart Claude Code and confirm add-deltachat appears in your skill list.
  5. Change into your own NanoClaw project root and start Claude Code there — the skill only makes sense inside that repo.
  6. Prepare a dedicated email account with an app password, and check compatibility at https://providers.delta.chat/ first.
  7. Ask Claude to "add the DeltaChat channel"; it will fetch the adapter, install the dependency, build and run the registration test.
  8. Fill in DC_EMAIL, DC_PASSWORD and the IMAP/SMTP host and port values in .env, restart the service, then use the invite link from the logs to start your first chat.
