Core trick

Voice intake builds a structured request, live web search validates providers, and a confirmation gate precedes any outreach.

Description

Delegate is a voice-first agent that acts on your behalf in real-world tasks. After a short conversational intake, it searches for relevant providers, validates them using live web data, and reaches out with consistent questions (simulated for demo). It then returns a clear summary highlighting tradeoffs and uncertainty so the user can decide confidently. Delegate emphasizes delegation with control — nothing happens without confirmation, and the agent never makes decisions for the user.

# Voice Practice Agent

**Cartesia x Anthropic Voice Agents Hackathon (Notion)** — AI voice agent that role-plays the other person in difficult conversations so you can practice before the real thing.

- **Expressive:** Cartesia TTS for natural, emotionally varied replies.
- **Advanced reasoning:** Claude for in-character dialogue and conversation memory.
- **Optional:** Notion (scenarios/memory), Exa (real-world context).

## Quick start

1. **Claim credits** (see [IMPLEMENTATION_GUIDE.md](./IMPLEMENTATION_GUIDE.md) Phase 0).
2. Create a `.env` in `backend/` with: `CARTESIA_API_KEY`, `ANTHROPIC_API_KEY`. For execution (provider search after confirm): `EXA_API_KEY` (see `.env.example`).
3. Backend: `cd backend && pip install -r requirements.txt && uvicorn app.main:app --reload`
4. Frontend: `cd frontend && npm install && npm run dev`
5. Open the app and pick a scenario → speak → hear the other person reply.

## How to check it

### 1. Set up keys
```bash
cd backend
cp .env.example .env
# Edit .env and set CARTESIA_API_KEY and ANTHROPIC_API_KEY
```

### 2. Start the backend
```bash
cd backend
pip install -r requirements.txt   # if you haven’t yet
uvicorn app.main:app --reload
```
Run the backend with `uvicorn app.main:app --reload --port 8009` (or another port). The frontend uses `http://localhost:8009` in `frontend/src/main.js` — change `API` there if your backend uses a different port.

### 3. Start the frontend
```bash
cd frontend
npm ins
