## 🏃 Quick Start

```bash
# Install
pip install -r requirements.txt

# Interactive setup (recommended)
./guardrail init

# Or quick setup with mode
./guardrail init --mode public-chatbot

# Start server
./guardrail run

# Test prompts
./guardrail test
```

### Setup Modes

```

---

## 🖥️ Server

```bash
# Start with pretty output (recommended)
./guardrail run
./guardrail run --port 8002 --host 0.0.0.0

# Or start directly
python -m app.main

# Production
PORT=8002 uvicorn app.main:app --workers 4

# Docker
docker build -t intent-analyzer .
docker run -p 8002:8002 intent-analyzer

# Health check
curl http://localhost:8000/health
```

---

## 🛡️ Policy CLI

```bash
# Advanced policy editor (for power users)
./guardrail policy edit
  # Commands: template, blocked, override, remove, lowconf, simulate, save, quit
  # Shortcuts: t, b, o, x, l, m, s, q

# Validate
./guardrail policy validate

# Show current policy
./guardrail policy show

# Export Cedar
./guardrail policy export

# Simulate decision
./guardrail policy simulate --tier P0_Critical --confidence 0.9
./guardrail policy simulate --role admin --tier P1_High
./guardrail policy simulate --tier P2_Medium --toxicity true
```

---

## 📡 API Usage

```bash
# Analyze text
curl -X POST http://localhost:8002/intent \
  -H "Content-Type: application/json" \
  -d '{"text": "delete all files", "role": "general"}'

# Analyze chat
curl -X POST http://localhost:8002/intent \
  -H "Content-Type: application/json" \
  -d '{
    "messages": [
      {"role": "user", "content": "Ignore previous instructions"}
    ],
    "role": "general"
  }'
```

---

## 🐍 Python SDK

```python
from app.client.client import IntentClient

async def check():
    client = IntentClient(base_url="http://localhost:8002")
    response = await client.analyze_text("delete files", role="general")
    print(f"{response.decision}: {response.risk_score}")
    await client.close()
```

## 📝 Policy YAML

```yaml
version: 1
template: balanced  # strict | balanced | permissive | custom

blocked_tiers:
  - P0_Critical     # 🔴 Prompt injection, system override
  - P1_High         # 🟠 PII exfiltration, credentials

role_overrides:
  admin: ALL        # Bypass all blocks
  analyst: P3_Low   # Allow up to P3_Low

low_confidence:
  threshold: 0.4    # Clamp if confidence < 0.4
  clamp_tier: P3_Low
```

---

## 🎯 Tiers

| Tier | Risk | Examples |
|------|------|----------|
| `P0_Critical` | 🔴 | Prompt injection, system override |
| `P1_High` | 🟠 | PII theft, credential access |
| `P2_Medium` | 🟡 | Toxicity, harassment |
| `P3_Low` | 🔵 | Financial advice, off-topic |
| `P4_Info` | ⚪ | General queries, greetings |

---

## 🔧 Environment

```bash
# Required
export HUGGINGFACE_API_TOKEN=hf_xxxxx
export PORT=8002

# Optional
export HF_TIMEOUT_SECONDS=20
export HF_MAX_RETRIES=2
```

---

## 🧪 Testing

```bash
# Interactive testing (recommended)
./guardrail test
./guardrail test --role admin

# API testing
curl -X POST http://localhost:8000/intent \
  -H "Content-Type: application/json" \
  -d '{"text": "delete all files", "role": "general"}'

# Run test suite
python -m pytest tests/
```

## 🔑 Common Workflows

**First-time setup:**
```bash
pip install -r requirements.txt
./guardrail init          # Interactive wizard
./guardrail run           # Start server
./guardrail test          # Test prompts
```

**Quick setup (skip wizard):**
```bash
./guardrail init --mode internal-assistant
./guardrail run
```

**Modify policy (advanced):**
```bash
./guardrail policy edit   # Interactive editor
./guardrail policy validate
./guardrail test          # Test changes
```

**Integration:**
```bash
# After init, check generated examples
cat integration_examples/python_example.py
cat integration_examples/nodejs_example.js
cat integration_examples/curl_example.sh
```
