🧩 Agent Cards

A Documentation Standard for Operational AI Agents

---

🧠 Overview

Agent Cards provide a lightweight, structured standard for documenting AI agents — covering their behavioral attributes, memory design, tool integrations, communication protocols, and governance metadata.

This work extends the model-centric transparency artifacts (Model Cards, FactSheets) into the agentic AI era, supporting reproducibility, comparability, and governance of autonomous and multi-agent systems.

📘 Accepted at: MICAI 2025 Workshops
