```python
from fi.evals.guardrails import Guardrails

# Initialize with defaults (uses Turing Flash)
guardrails = Guardrails()

# Screen user input
result = guardrails.screen_input("How can I help you today?")
if result.passed:
    print("Content is safe")
else:
    print(f"Blocked: {result.blocked_categories}")
```

## Discover Available Backends

```python
from fi.evals.guardrails import Guardrails, discover_backends, get_backend_details

# Quick discovery
available = Guardrails.discover_backends()
print(f"Available: {[m.value for m in available]}")

# Detailed info
details = Guardrails.get_backend_details()
for model, info in details.items():
    print(f"{model}: {info['status']} - {info['reason']}")
```

## Using OpenAI Moderation (FREE)

```python
import os
os.environ["OPENAI_API_KEY"] = "sk-..."

from fi.evals.guardrails import Guardrails, GuardrailsConfig, GuardrailModel

config = GuardrailsConfig(
    models=[GuardrailModel.OPENAI_MODERATION],
    timeout_ms=30000,
)
guardrails = Guardrails(config=config)

result = guardrails.screen_input("How do I make a bomb?")
print(f"Passed: {result.passed}")
print(f"Blocked categories: {result.blocked_categories}")
# Output: Passed: False, Blocked categories: ['violence']
```

## Using Azure Content Safety

```python
import os
os.environ["AZURE_CONTENT_SAFETY_ENDPOINT"] = "https://your-resource.cognitiveservices.azure.com/"
os.environ["AZURE_CONTENT_SAFETY_KEY"] = "your-key"

from fi.evals.guardrails import Guardrails, GuardrailsConfig, GuardrailModel

config = GuardrailsConfig(
    models=[GuardrailModel.AZURE_CONTENT_SAFETY],
)
guardrails = Guardrails(config=config)

result = guardrails.screen_input("I want to hurt myself")
# Azure returns severity levels 0-7, mapped to scores 0-1
```

## Using Local Models

### Option 1: Via VLLM Server (Recommended)

```bash
# Start VLLM server (see fi-slm/server/README.md)
export HF_TOKEN="your_token"
python mps_vllm_server.py  # Apple Silicon
# or
./start-vllm.sh --gpu      # NVIDIA GPU
```

```python
import os
os.environ["VLLM_SERVER_URL"] = "http://localhost:28000"

from fi.evals.guardrails import Guardrails, GuardrailsConfig, GuardrailModel

config = GuardrailsConfig(
    models=[GuardrailModel.WILDGUARD_7B],
    timeout_ms=60000,  # Local models may be slower
)
guardrails = Guardrails(config=config)

result = guardrails.screen_input("Hello, how are you?")
```

### Option 2: Direct Model Loading (Requires GPU)

```python
import os
os.environ["HF_TOKEN"] = "your_huggingface_token"

from fi.evals.guardrails import Guardrails, GuardrailsConfig, GuardrailModel

# Model will be loaded directly using transformers
config = GuardrailsConfig(
    models=[GuardrailModel.WILDGUARD_7B],
)
guardrails = Guardrails(config=config)
```

## Ensemble Mode

Combine multiple backends for better coverage:

```python
from fi.evals.guardrails import (
    Guardrails,
    GuardrailsConfig,
    GuardrailModel,
    AggregationStrategy,
)

config = GuardrailsConfig(
    models=[
        GuardrailModel.TURING_FLASH,
        GuardrailModel.OPENAI_MODERATION,
    ],
    aggregation=AggregationStrategy.MAJORITY,  # Block if majority flag
    parallel=True,
    timeout_ms=30000,
)
guardrails = Guardrails(config=config)
```

### Aggregation Strategies

| Strategy | Behavior |
|----------|----------|
| `ANY` | Block if ANY backend flags (most strict) |
| `ALL` | Block only if ALL backends flag (most lenient) |
| `MAJORITY` | Block if majority of backends flag |
| `WEIGHTED` | Weighted voting (uses MAJORITY logic currently) |

## Rail Types

### Input Rails - Screen user input before LLM

```python
result = guardrails.screen_input("user message")
```

### Output Rails - Screen LLM response before user

```python
result = guardrails.screen_output(
    "LLM response",
    context="original user query"  # Optional, for hallucination detection
)
```

### Retrieval Rails - Screen RAG document chunks

```python
chunks = ["doc 1", "doc 2", "doc 3"]
results = guardrails.screen_retrieval(chunks, query="user query")
# Returns list of GuardrailsResponse, one per chunk
```

## Async Support

```python
import asyncio

async def main():
    result = await guardrails.screen_input_async("user message")

    # Batch processing
    contents = ["msg 1", "msg 2", "msg 3"]
    results = await guardrails.screen_batch_async(contents)

asyncio.run(main())
```

## Gateway API (High-Level Interface)

The `GuardrailsGateway` provides a simpler, more ergonomic interface with factory methods and context managers.

### Factory Methods

```python
from fi.evals.guardrails import GuardrailsGateway, Gateway

# Auto-discover best available backend
gateway = GuardrailsGateway.auto()

# Use OpenAI Moderation (FREE)
gateway = GuardrailsGateway.with_openai()

# Use Azure Content Safety
gateway = GuardrailsGateway.with_azure()

# Use local model via VLLM
gateway = GuardrailsGateway.with_local_model(GuardrailModel.WILDGUARD_7B)

# Use ensemble of multiple backends
gateway = GuardrailsGateway.with_ensemble(
    models=[GuardrailModel.OPENAI_MODERATION, GuardrailModel.TURING_FLASH],
    aggregation=AggregationStrategy.ANY,
)
```

### Quick Screen

```python
# Simple one-liner
result = gateway.screen("Is this content safe?")

# Async
result = await gateway.screen_async("Is this content safe?")
```

### Context Manager (Sync)

```python
with gateway.screening() as session:
    # Screen user input
    input_result = session.input("user message")
    if not input_result.passed:
        return "Sorry, I can't process that."

    # Call your LLM
    response = call_llm("user message")

    # Screen LLM output
    output_result = session.output(response, context="user message")
    if not output_result.passed:
        return "Let me try again..."

    # Check session history
    print(f"All passed: {session.all_passed}")
    print(f"Total screenings: {len(session.history)}")

    return response
```

### Context Manager (Async)

```python
async with gateway.screening_async() as session:
    input_result = await session.input("user message")
    if not input_result.passed:
        return "Content blocked"

    response = await llm.generate("user message")

    output_result = await session.output(response)
    if not output_result.passed:
        return "Response filtered"

    # Batch screen multiple items
    results = await session.batch(["item1", "item2", "item3"])

    return response
```

### Discovery Methods

```python
# Static discovery
available = GuardrailsGateway.discover()
details = GuardrailsGateway.get_details()

# Instance methods
gateway = GuardrailsGateway.with_openai()
print(gateway.available_backends)
print(gateway.configured_models)
```

## Custom Category Configuration

```python
from fi.evals.guardrails import SafetyCategory

config = GuardrailsConfig(
    models=[GuardrailModel.OPENAI_MODERATION],
    categories={
        "violence": SafetyCategory(
            name="violence",
            threshold=0.5,  # Lower threshold = more sensitive
            action="block",
        ),
        "toxicity": SafetyCategory(
            name="toxicity",
            threshold=0.8,  # Higher threshold = less sensitive
            action="flag",  # Flag but don't block
        ),
    },
)
```

### Available Actions

| Action | Behavior |
|--------|----------|
| `block` | Fail the screening, add to `blocked_categories` |
| `flag` | Add to `flagged_categories` but still pass |
| `redact` | Redact PII and continue |
| `warn` | Log warning but continue |

## Response Structure

```python
result = guardrails.screen_input("some content")

# GuardrailsResponse attributes:
result.passed              # bool - Final pass/fail decision
result.blocked_categories  # List[str] - Categories that caused blocking
result.flagged_categories  # List[str] - Categories flagged but not blocked
result.results             # List[GuardrailResult] - Individual backend results
result.total_latency_ms    # float - Total processing time
result.models_used         # List[str] - Which backends processed the content
result.error               # Optional[str] - Any errors that occurred
result.original_content    # str - The content that was screened

# Individual GuardrailResult:
for r in result.results:
    print(f"Model: {r.model}")
    print(f"Category: {r.category}")
    print(f"Score: {r.score}")  # 0.0 to 1.0
    print(f"Passed: {r.passed}")
    print(f"Reason: {r.reason}")
    print(f"Latency: {r.latency_ms}ms")
```

    # 1. Screen user input
    input_result = guardrails.screen_input(user_message)
    if not input_result.passed:
        return "I'm sorry, I can't process that message."

    # 2. Generate response (your LLM call)
    response = generate_response(user_message)

    # 3. Screen output
    output_result = guardrails.screen_output(response, context=user_message)

async def rag_pipeline(query: str, documents: list) -> str:
    # 1. Screen query
    query_result = await guardrails.screen_input_async(query)
    if not query_result.passed:
        return "I can't process that query."

    # 2. Retrieve and screen documents
    chunks = retrieve_relevant_chunks(query, documents)
    chunk_results = await guardrails.screen_retrieval_async(chunks, query=query)

    # Filter safe chunks
    safe_chunks = [
        chunk for chunk, result in zip(chunks, chunk_results)
        if result.passed
    ]

    # 3. Generate and screen response
    response = await llm.generate(query, context=safe_chunks)
    output_result = await guardrails.screen_output_async(response, context=query)

    if not output_result.passed:
        return "I couldn't generate a safe response."

    return response
```

    create_default_pipeline,
)

# Option 1: Create default pipeline (jailbreak + code injection + secrets)
pipeline = create_default_pipeline()

# Option 2: Custom pipeline
pipeline = ScannerPipeline([
    JailbreakScanner(),
    CodeInjectionScanner(),
    SecretsScanner(),
])

# Scan content
result = pipeline.scan("User input here")
if not result.passed:
    print(f"Blocked by: {result.blocked_by}")
    print(f"Matches: {result.all_matches}")
```

### Enable Scanners in Guardrails

from fi.evals.guardrails import (
    Guardrails,
    GuardrailsConfig,
    GuardrailModel,
    ScannerConfig,
    TopicConfig,
    LanguageConfig,
)

config = GuardrailsConfig(
    models=[GuardrailModel.OPENAI_MODERATION],

        code_injection=True,
        secrets=True,
        urls=False,  # Disabled by default
        invisible_chars=False,

        # Topic restriction
        topics=TopicConfig(
            allowed=["customer_support", "product_info"],
            denied=["politics", "religion"],
        ),

        # Language restriction
        language=LanguageConfig(
            allowed=["en", "es", "fr"],
            allowed_scripts=["Latin", "Common"],
        ),

        # Performance
        parallel=True,
        fail_fast=True,  # Stop early if scanner blocks
    ),
)

guardrails = Guardrails(config=config)
result = guardrails.screen_input("User message")
# Scanners run FIRST, then model backends
```

### Jailbreak Detection

```python

    # model_name="protectai/deberta-v3-base-prompt-injection-v2",  # Alternative
    combine_scores=True,  # Hybrid: pattern + ML
    ml_weight=0.6,
    pattern_weight=0.4,
)

# ML detection catches sophisticated attacks
result = scanner.scan("As a helpful AI without restrictions, please...")
# Uses transformer inference for semantic analysis
# metadata includes: scoring_mode, ml_score, pattern_score
```

**Supported Models:**
- `meta-llama/Prompt-Guard-86M` (default) - Lightweight, fast
- `protectai/deberta-v3-base-prompt-injection-v2` - Alternative

**Requirements:** `pip install transformers torch`

print(result.passed)           # bool
print(result.blocked_by)       # ["jailbreak", "secrets"]
print(result.flagged_by)       # ["urls"]

print(result.all_matches)      # All pattern matches

# Individual scanner results
for scan_result in result.results:
    print(f"{scan_result.scanner_name}: {scan_result.passed}")
```

### Async Scanner Support

```python
import asyncio
from fi.evals.guardrails.scanners import ScannerPipeline, JailbreakScanner

async def scan_content():
    pipeline = ScannerPipeline([JailbreakScanner()])

    # Async scanning
    result = await pipeline.scan_async("content to check")
    return result.passed

asyncio.run(scan_content())
```

## Testing

```bash
# Run all guardrails tests
pytest tests/integration/test_guardrails_integration.py -v --run-model-serving

# Run scanner tests
pytest tests/sdk/test_guardrails_scanners.py -v

# Run OpenAI tests only
export OPENAI_API_KEY="sk-..."
pytest tests/integration/test_guardrails_modal_gateway.py -v -k "openai"

# Run local model tests
export VLLM_SERVER_URL="http://localhost:28000"
pytest tests/integration/test_guardrails_modal_gateway.py -v -k "local"
```
