Minimal embedded gateway + @harness example.
Example: Minimal
Overview
Smallest working example using auto_instrument() with OpenAI and LangGraph. Zero decorator — governance applied via runtime patching.
Why It Matters
Proves auto-instrumentation works with minimal code before integrating into a larger app.
Prerequisites
pip install "agentrust-sdk[embedded]" openai langgraphStep-by-Step Guide
cd examples/
python minimal.pyKey code pattern:
from agentrust_sdk import auto_instrument, embed_gateway
embed_gateway()
auto_instrument()
# existing OpenAI/LangGraph code runs unchangedExamples
Source: examples/minimal.py
Best Practices
- Run with embedded gateway first (no API key needed)
- Verify with
agentrust audit tail
Common Mistakes
- Importing openai before
auto_instrument()
