Agentic Workflows

The Power of Tools in AI

Tools bridge static language models and real-world execution, turning conversational agents into autonomous digital workers.

What is an AI Tool?

In a multi-agentic workflow, a Tool is a defined capability granted to an AI model so it can interact with external systems, retrieve information, or perform state-changing actions.

It is an API endpoint, script, or function wrapped in a schema.
The LLM decides when and how to call it based on the user's prompt.
It breaks the LLM out of its knowledge-cutoff isolation.
