.claude/skills/add-signal/SKILL.md

add-signal is a skill for Claude Code from thmtz/nanoclaw-fleet. It costs 22 tokens per session (1,408 once invoked), scanned A, original, MIT.

A Signal messaging integration for NanoClaw that connects through signal-cli, a command-line program for sending and receiving Signal messages.

In plain words
What is it for?
Use it to add Signal as a messaging channel, including the adapter, registration, credentials, and tests.
Why use it?
It lets NanoClaw communicate through Signal without relying on a separate chat service or extra package dependencies.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

add-signal scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

No npm packages to install — the adapter uses only Node.js builtins (`node:net`, `node:child_process`, `node:fs`).

How it starts

The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Add Signal Channel

Adds Signal messaging support via a native adapter that speaks JSON-RPC to a signal-cli TCP daemon. No Chat SDK bridge, no npm deps — only Node.js builtins.

Prerequisites

signal-cli installed and a Signal account linked:

  • macOS: brew install signal-cli
  • Linux: download from GitHub releases
  • Link your account: signal-cli -a +1YOURNUMBER link (follow the QR instructions)

Install

NanoClaw doesn't ship channels in trunk. This skill copies the Signal adapter and its tests in from the channels branch.

Pre-flight (idempotent)

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

  • src/channels/signal.ts and src/channels/signal.test.ts both exist
  • src/channels/index.ts contains import './signal.js';

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

1. Fetch the channels branch

git fetch origin channels

2. Copy the adapter and tests

git show origin/channels:src/channels/signal.ts      > src/channels/signal.ts
git show origin/channels:src/channels/signal.test.ts > src/channels/signal.test.ts

3. Append the self-registration import

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

import './signal.js';

4. Build

pnpm run build

No npm packages to install — the adapter uses only Node.js builtins (node:net, node:child_process, node:fs).

Credentials

Add to .env:

SIGNAL_ACCOUNT=+1YOURNUMBER

Optional settings

# TCP daemon host and port (default: 127.0.0.1:7583)
SIGNAL_TCP_HOST=127.0.0.1
SIGNAL_TCP_PORT=7583

# Path to the signal-cli binary (default: resolved on PATH)
SIGNAL_CLI_PATH=/usr/local/bin/signal-cli

# Whether NanoClaw manages the daemon lifecycle (default: true).
# Set to false if you run signal-cli daemon externally.
SIGNAL_MANAGE_DAEMON=true

# signal-cli data directory (default: ~/.local/share/signal-cli)
SIGNAL_DATA_DIR=~/.local/share/signal-cli

What ships with it

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
