# AISA — Agentic AI Systems Architecture

---

## Overview

AISA (Agentic AI Systems Architecture) is a system-level reference architecture
for the design, deployment, evaluation, and governance of agentic AI systems.

It frames agentic AI as an end-to-end system problem, addressing the
architectural challenges introduced by autonomous, tool-using,
and long-horizon AI behavior.

---

## Motivation

As large language models evolve into persistent and goal-directed agents,
key challenges increasingly arise at the system level, including:

- Fragmented agent architectures
- Brittle orchestration and tool usage
- Limited observability and evaluation
- Unclear governance and accountability

AISA introduces a unified architectural model that integrates reasoning,
infrastructure, evaluation, deployment, and governance.

---

## Architectural Model

AISA decomposes agentic AI systems into seven high-level layers:

1. **LLM Foundation** — language understanding and reasoning  
2. **Tool & Environment** — controlled external actions  
3. **Cognitive Agent** — planning, goals, and memory  
4. **Agentic Infrastructure** — orchestration and coordination  
5. **Evaluation & Feedback** — continuous behavioral assurance  
6. **Development & Deployment** — lifecycle management  
7. **Governance, Ethics & Policy** — system-wide constraints  

This separation of concerns enables predictable behavior,
continuous evaluation, and enforceable governance.

---

## System Perspective

AISA treats agentic AI systems as composed, multi-layered systems
whose behavior emerges from interactions across reasoning,
execution, infrastructure, and policy layers.

This perspective supports system-level analysis and comparison
across different agentic designs.

---

## Contributions

This work:

- Proposes a unified layered reference architecture for agentic AI systems  
- Clarifies responsibilities and boundaries across system components  
- Elevates evaluation, operations, and governance to first-class concerns  
- Provides a shared vocabulary for research and practice  

---

## Intended Use

AISA is intended for:

- Research on agentic and autonomous AI systems  
- Design of production-grade agent architectures  
- Evaluation and comparison of agentic behaviors  
- Governance and risk analysis of deployed AI systems  

The framework applies to both single-agent and multi-agent systems.
