Add Signal Channel (add-signal)

Wires a Signal messaging channel into NanoClaw using a native signal-cli adapter and phone device-linking.

What it does

Automates adding Signal support to a NanoClaw assistant. It installs signal-cli if missing, copies a native adapter (Node.js builtins only — no Chat SDK bridge) plus its registration test into src/channels/, appends a single self-registration import to the channel barrel, pins the qrcode dependency, then builds and runs the registration test.

The credential step is a device link, not a bot API: signal-cli prints an sgnl://linkdevice… URL and a terminal QR, you scan it from the phone that already runs Signal, and that number becomes the assistant's identity. An alternative path (captcha → SMS/voice verification → profile name) is documented for those who want a dedicated number.

The doc also spells out supported features (markdown → Signal text styles, quoted replies, DM typing indicators, Note to Self inbound routing, voice-message detection) and unsupported ones (outbound attachments, edits/deletes, reactions), plus a long troubleshooting section.

Who it's for

  • NanoClaw users who want their assistant reachable over Signal
  • Privacy-minded operators who prefer Signal to Telegram or Slack
  • Developers comfortable with terminals, pnpm, launchd/systemd and SQLite queries

Note: this skill assumes the NanoClaw repo layout (setup/ scripts, the ncl CLI, data/v2.db) — it will not work standalone.

Examples

  1. Personal assistant: after linking, message your own Note to Self chat to ask the agent for reminders or lookups.
  2. Small team group: add the Signal number to a group, send a message, then run ncl wirings create --messaging-group-id mg-… --agent-group-id ag-… to bind it to an agent group.
  3. Debugging silence: check grep "Signal channel connected" logs/nanoclaw.log, and when senders are dropped as not_member, grant access with ncl users create + ncl roles grant.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the .claude/skills/add-signal folder from the GitHub repo nanocoai/nanoclaw into my ~/.claude/skills/add-signal/.
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 /tmp/nanoclaw && mkdir -p ~/.claude/skills && cp -r /tmp/nanoclaw/.claude/skills/add-signal ~/.claude/skills/

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

  1. Open a terminal and clone the repository: git clone https://github.com/nanocoai/nanoclaw.git
  2. Enter the project folder: cd nanoclaw
  3. Copy the skill into your user skills directory: mkdir -p ~/.claude/skills && cp -r .claude/skills/add-signal ~/.claude/skills/
  4. Make sure signal-cli can be installed (Homebrew on macOS, native release binary on Linux) — the skill's setup/install-signal-cli.sh handles this for you.
  5. Start Claude Code from the NanoClaw project root and ask: "Add the Signal channel."
  6. When the QR appears, open Signal on your phone → Settings → Linked Devices → Link New Device and scan it (the link expires in ~3 minutes).
  7. Once the linked number is saved to SIGNAL_ACCOUNT, restart the service, send any message from your Signal app, then wire the resulting group with /init-first-agent or /manage-channels.
