Contextual Engineering Patterns: Architecting Adaptable AI Agents
Reference implementations for the architectural patterns defined in the book "Contextual Engineering: Architecting Adaptable AI Agents for the Real World" by Tobi Lekan Adeosun.
π Overview
Standard AI agents are designed for the "Abundance Baseline" of Silicon Valleyβperfect internet, unlimited power, and institutional trust. When deployed in the Global South, these agents fail due to the "Agentic Gap" between their reasoning capabilities and environmental realities.
This repository contains the Python reference implementations for the three core adaptation layers introduced in the book:
- Infrastructure Adapter: Handling offline states and compute scarcity.
- Cultural Adapter: Managing semantic drift and high-context communication.
- Safety Adapter: Enforcing constitutional guardrails and Human-in-the-Loop (HITL) workflows.
β‘ Quick Start (Hybrid Router)
How to use the Infrastructure Adapter to route traffic based on connectivity:
from src.infrastructure.inference_router import HybridRouter
# Initialize router with cost/latency preferences
router = HybridRouter(preference="economy", offline_fallback=True)
# The router automatically checks network status (N(t))
model_choice = router.select_model(
prompt="Summarize this contract",
complexity_score=0.85
)
print(f"Routing to: {model_choice}")
# Output: "Llama-3-8B-Local" (if offline) or "GPT-4o" (if online)
## π Repository Structure
The code is organized by the "Adapter Layer" it serves, matching the chapters of the manuscript.
