Agent-Reg: Building an Open Agent Registry for A2A Protocol

Introduction During these scorching August days, I took the opportunity to thoroughly read Google’s A2A protocol specification and try to understand how to use its concepts to design an enterprise Agent architecture, possibly free from technological or platform constraints. What is A2A? The Agent2Agent (A2A) Protocol is an open standard designed and publicly shared by Google to facilitate communication and collaboration among AI agents. The standardization of AI interoperability model is a topic that has been discussed since the very first moments when we started talking about Agents, and there are several reasons for this:...

Beyond RAG: How to Effectively Analyze an Excel File Using an LLM

Abstract As AI developers, we’re always looking for ways to make data more accessible and queryable through natural language. While Retrieval-Augmented Generation (RAG) has revolutionized how we interact with unstructired textual documents, it falls short when dealing with structured data. The RAG approach is so powerful that users or even early stage AI developers may fall in the illusion that it can be applied to any kind of data, including structured data like Excel files....

Policy Puppetry Prompt Injection

Policy Puppetry Prompt Injection A few days ago, I experimented with some Jailbreaking techniques, which I share in the repo. I started from a HiddenLayer article published a few weeks ago, where the research team described a rather creative and ingenious jailbreaking technique to bypass safety guardrails and the alignment of frontier models. The technique appears to be universal and applicable with a single prompt to multiple models, capable of revealing typically unsafe content or even portions of the native system prompt....

Langchain pt. 2 - Data Analysis through Agents

Intro In the previous article I gave a very brief overview of LangChain, describing its main concepts with some examples with unstructured data in pdf format. Following the same approach, in this article we will give a brief introduction to Agents and proceed by trying to answer an ambitious question: leveraging these new AI tools, can we carry out data analysis on our DB without any knowledge of SQL nor of the data model, simply starting from a text prompt in natural language?...
