# Clawfinger — OpenClaw Voice Gateway Plugin

> **Requires**: [Trac-Systems/clawfinger](https://github.com/Trac-Systems/clawfinger) — the local voice gateway and Android phone app. Install and run the gateway before using this plugin.

OpenClaw plugin that gives agents full control over the Clawfinger local voice gateway and its active phone calls.

## What It Does

- **Call control**: Dial outbound calls, hang up, inject spoken messages into live calls
- **LLM takeover**: Replace the gateway's local LLM with agent-driven responses in real time
- **Context injection**: Push knowledge into the LLM context so the phone assistant has facts you provide
- **Instruction management**: Set system prompts at global, session, or one-shot turn scope
- **Call policy**: Read and update greetings, auto-answer, caller filtering, max duration
- **Observation**: Query session state, conversation history, and gateway health

## Dependencies

- **Gateway**: A running Clawfinger voice gateway (`app.py` on `127.0.0.1:8996`)
- **Node**: `@sinclair/typebox` (install via `npm install` in plugin directory)
- **Phone**: Android phone with the PhoneBridge app, connected via ADB reverse port forwarding

## Configuration

In `~/.openclaw/openclaw.json`:

```json
