Learn how to implement your first AI agents with the help of RubyLLM. Define a chat interface with access to a set of SERP tools that LLM models can use in their work.

RubyFlow's platform is a resource for Ruby developers, offering insights into Ruby programming language, Ruby on Rails framework, and Ruby-related tools. Through articles, tutorials, and community discussions, RubyFlow offers insights into building web applications with Ruby and Rails. Developers can learn about Ruby gems, Rails conventions, and best practices in Ruby development to write clean and maintainable code.

RubyLLM enables building AI agents in Ruby on Rails by combining LLM chat with custom tools. The tutorial walks through defining tools as Ruby classes (e.g., LookupProduct and SearchGoogleShopping via SerpApi), wiring them into a chat with `with_tools`, and wrapping everything into a reusable agent class inheriting from RubyLLM::Agent. A PriceMonitorAgent example demonstrates how agents can autonomously query internal product data and live Google Shopping results to answer complex pricing questions. Debugging tool calls is covered via chat message inspection and SerpApi's Search Inspector.
