ADL: A Declarative Language for Agent-Based Chatbots (2504.14787v1)

Abstract: There are numerous agent frameworks capable of creating and orchestrating agents to address complex tasks. However, these frameworks are often too complicated for customer service professionals, who may not have much programming experience but still need an easy way to create chatbots with rich business logic. In this work, we introduce ADL, a Declarative Language for Agent-Based Chatbots. ADL simplifies chatbot development by using natural language programming at its core, making it easier for a broad audience to customize and build task-oriented chatbots. It includes four types of agents and supports integration with custom functions, tool use, and third-party agents. ADL abstracts away implementation details, offering a declarative way to define agents and their interactions, which could ease prompt engineering, testing and debugging. MICA, a multi-agent system designed to interpret and execute ADL programs, has been developed and is now available as an open-source project at https://github.com/Mica-labs/MICA. Its user documentation can be found at https://mica-labs.github.io/.
