About

DSPy Guardrails is a comprehensive suite of AI guardrails built with DSPy. Each guardrail is implemented as a self-contained module that can be used to test and validate different types of content moderation and security checks.

• Modular design — Each guardrail type is implemented as a separate, self-contained module
• Programmatic testing — Run guardrails directly in Python for fast iteration
• Comprehensive coverage — Covers major content moderation and security scenarios
• DSPy integration — Leverages DSPy's programmatic prompting for consistent, reliable results
• Type safety — Full type hints and dataclass definitions for robust implementations

Quick Start

Install

Install dspy-guardrails with uv (recommended)

uv add dspy-guardrails

Install with pip (alternative)

pip install dspy-guardrails

Usage

Basic Usage

import dspy
from dspy_guardrails import guardrail

# Configure DSPy (required)
lm = dspy.LM("openrouter/google/gemini-2.5-flash-preview-09-2025")
guardrail.configure(lm=lm)

# Create and run guardrails
topic_guardrail = guardrail.Topic(topic_scopes=["AI", "Machine Learning"])
result = guardrail.Run(topic_guardrail, "I want to learn about neural networks")
print(f"Allowed: {result.is_allowed}")  # True

Multiple Guardrails

Assumes guardrail.configure(lm=lm) has already been called.

all_guardrails = [
    guardrail.Topic(topic_scopes=["AI"]),
    guardrail.Nsfw(),
    guardrail.Pii(),
]
result = guardrail.Run(all_guardrails, "Safe AI content")
print(f"All passed: {result.is_allowed}")  # True

Early Return

Stop execution on the first failing guardrail.

guardrails = [guardrail.Topic(topic_scopes=["AI"]), guardrail.Nsfw()]
result = guardrail.Run(guardrails, "Risky content", early_return=True)
print(result.is_allowed)

For more examples and patterns, see the complete quickstart guide and guardrail types.

Development

Code Quality

This project uses several tools to maintain code quality:

• Ruff: Linting and formatting
• isort: Import sorting
• pytest: Testing framework

Available commands:

# Run all quality checks
uv run poe clean

# Individual checks
uv run poe lint          # Ruff linting
uv run poe format        # Ruff formatting
uv run poe sort          # Import sorting

Testing

Run tests using pytest:

# Run all tests
uv run pytest

# Run specific test
uv run pytest path/to/test.py::test_name
