Run a real-time AI phone agent using Twilio, Deepgram, and ElevenLabs. Handles incoming calls, transcribes audio, generates responses via LLM, and speaks back via streaming TTS. Use when user wants to: (1) Test voice AI capabilities, (2) Handle phone calls programmatically, (3) Build a conversational voice bot.

What this skill does


# Phone Agent Skill

Runs a local FastAPI server that acts as a real-time voice bridge.

## Architecture

```
Twilio (Phone) <--> WebSocket (Audio) <--> [Local Server] <--> Deepgram (STT)
                                                  |
                                                  +--> OpenAI (LLM)
                                                  +--> ElevenLabs (TTS)
```

## Prerequisites

1.  **Twilio Account**: Phone number + TwiML App.
2.  **Deepgram API Key**: For fast speech-to-text.
3.  **OpenAI API Key**: For the conversation logic.
4.  **ElevenLabs API Key**: For realistic text-to-speech.
5.  **Ngrok** (or similar): To expose your local port 8080 to Twilio.

## Setup

1.  **Install Dependencies**:
    ```bash
    pip install -r scripts/requirements.txt
    ```

2.  **Set Environment Variables** (in `~/.moltbot/.env`, `~/.clawdbot/.env`, or export):
    ```bash
    export DEEPGRAM_API_KEY="your_key"
    export OPENAI_API_KEY="your_key"
    export ELEVENLABS_API_KEY="your_key"
    export TWILIO_ACCOUNT_SID="your_sid"
    export TWILIO_AUTH_TOKEN="your_token"
    export PORT=8080
    ```

3.  **Start the Server**:
    ```bash
    python3 scripts/server.py
    ```

4.  **Expose to Internet**:
    ```bash
    ngrok http 8080
    ```

5.  **Configure Twilio**:
    - Go to your Phone Number settings.
    - Set "Voice & Fax" -> "A Call Comes In" to **Webhook**.
    - URL: `https://<your-ngrok-url>.ngrok.io/incoming`
    - Method: `POST`

## Usage

Call your Twilio number. The agent should answer, transcribe your speech, think, and reply in a natural voice.

## Customization

- **System Prompt**: Edit `SYSTEM_PROMPT` in `scripts/server.py` to change the persona.
- **Voice**: Change `ELEVENLABS_VOICE_ID` to use different voices.
- **Model**: Switch `gpt-4o-mini` to `gpt-4` for smarter (but slower) responses.

watch

Included

Watch a video (URL or local path). Downloads with yt-dlp, extracts auto-scaled frames with ffmpeg, pulls the transcript from captions (or Whisper API fallback), and hands the result to Claude so it can answer questions about what's in the video.

physical-ai-defect-image-generation

Included

Use when the user wants to orchestrate defect image generation, run associated setup, or handle outputs on OSMO. The Day 0 path handles cold-start with USD-to-ROI, image-edit augmentation, and AnomalyGen to create initial PCBA datasets. The Day 1 path performs inference and labeling on real images. This skill helps with first-time asset setup, creation of finetuning checkpoints, and configuring deployment.

accelint-react-best-practices

Included

React performance optimization and best practices. ALWAYS use this skill when working with any React code - writing components, hooks, JSX; refactoring; optimizing re-renders, memoization, state management; reviewing for performance; fixing hydration mismatches; debugging infinite re-renders, stale closures, input focus loss, animations restarting; preventing remounting; implementing transitions, lazy initialization, effect dependencies. Even simple React tasks benefit from these patterns. Covers React 19+ (useEffectEvent, Activity, ref props). Triggers - useEffect, useState, useMemo, useCallback, memo, inline components, nested components, components inside components, re-render, performance, hydration, SSR, Next.js, useDeferredValue, combined hooks.

humanizer

Included

Humanize AI-generated text by detecting and removing patterns typical of LLM output. Rewrites text to sound natural, specific, and human. Uses 28 pattern detectors, 560+ AI vocabulary terms across 3 tiers, and statistical analysis (burstiness, type-token ratio, readability) for comprehensive detection. Use when asked to humanize text, de-AI writing, make content sound more natural/human, review writing for AI patterns, score text for AI detection, or improve AI-generated drafts. Covers content, language, style, communication, and filler categories.

generating-mermaid-diagrams

Included

Salesforce architecture diagrams using Mermaid with ASCII fallback. Use this skill when generating text-based diagrams for Salesforce architecture, OAuth flows, ERDs, integration sequences, or Agentforce structure. TRIGGER when: user says "diagram", "visualize", "ERD", or asks for sequence diagrams, flowcharts, class diagrams, or architecture visualizations in Mermaid. DO NOT TRIGGER when: user wants PNG/SVG image output (use generating-visual-diagrams), or asks about non-Salesforce systems.
