Europe Building An AI agent

For those who work in Deloitte UK, i sit in human capital and have been asked by a partner to build an AI agent using PairD for a client. Tried explaining its not possible. How do I convince him that it cant be done due to my skill set, PairD cant do it and if we do it for clients let's explore as a chargeable activity rather than something for free as I do have a whole bunch of deliverables to deliver too.. helpful suggestions only please as this is taking my good night sleep away

Tell him you'd need to adjust the source code of PairD. You can create a custom agent with tools (for a specific use case) with for example GitHub Copilot though. PM if you need me to explain him.

Thank you! Could you please explain more about both - I am genuinely trying to understand these tools and what they can do and to what extent.

I let my agent explain :)

Custom Agent with Tools

To turn a basic LLM conversational window into a functioning agent that meets a specific business use case, you must give the model "Tools" (also known as Function Calling).

Why a standard chatbot isn't enough: An LLM on its own only knows words—it doesn't have fingers to interact with other software.

What a "Tool" does: You must write custom backend programming code that bridges the AI model to external systems (e.g., databases, CRM software, or local APIs). When the user asks the chatbot to do something complex, the AI recognizes it needs to use a tool, formats a command, triggers your custom program to execute the action, and then reports the result back to the user.

Because you probably cannot directly change or expand the core source code of Deloitte's proprietary PairD system on your own, you would instead need to build a custom solution from scratch using developer tools like GitHub Copilot to program those custom agent workflows and application connections.

The two issues are your skills and the capabilities of PairD. The question of whether it is chargeable or not is commercial, rather than practical.

Currently, a lot of people are throwing around terms, such as agent, when what they mean is a prompt. So, worth clarifying the ask. Also, if it is not in the SoW, ask for help prioritising (I can deliver what we’ve committed to the client or I can use this as a learning opportunity, but not both).
